Galaxy Tab 'forgets' to reconnect to wifi?

I've notice a slight issue with my Tab. Sometimes, when it's been left sleeping for a while it 'forgets' to go back to wifi and stays on 3G connectivity, even though I'm sitting right next to the wlan router. If I check the wifi settings, the network is listed as 'out of range'. If I turn off wifi and then back on again, it connects without any trouble.
Has anyone else noticed this behaviour?

This is most certainly a router issue. The simplest fix is to reserve ip up for the tab and use fixed up settings.
I do this with all my LAN devices anyway because it adds a little security, as well as better interconnectivity.
But really you should investigate the router.

Somehow I doubt that. I'm using DD-WRT running on the classic LinkSys WRT54G, a combo that is widely famed for it reliability. I also have the router set up to serve a fixed IP to the Galaxy Tab, determined by the MAC address of the Tabs wireless interface.
I'm also running quite a few other wifi devices with the router, including three other android devices (G1, milestone, nook), and none of them show the same behavior.

I see... how many of your other devices use a dual band revision n radio? In my experience this can be a headache, even for custom firmware.

None, as far as I know. I'm not entirely sure about my wifes Motorola Milestone, but I'm pretty sure the G1 and the nook use bog standard 802.11g. I think you're right that this might be the problem. Any ideas how to improve that? It's not really a problem, just a slight blemish on the otherwise awesome experience.

This is well known android behavior making wi-fi sleep to preserver battery.
There are some mods to keep it on when sleeping.

Yes, and there's nothing wrong with that. I certainly don't want wifi on all the time, I just want it to reconnect when it wakes up.

Ill look into your router tomorrow, but atm I'd say there wont be much you can do other than force g only on the router. This will stop the tab from sending crc/ plcp overhead on both bands. Crazy as it sounds, the tabs radio is actually interfering with itself in this scenario.

I just replaced my HTC HD2 with the Samsung Galaxy Tab and have the exact same problem. The HD easily picked up my work and home WiFi when I moved between them, but the Tab 'forgets' to reconnect after standby.

I'm having this problem too. Every morning I need to turn off the wifi, then immediately turn it back on, before it will reconnect. This is with an Asus WL520GC running DD-WRT.

Yes, seems to be a router/device compatibility issue.
My tab works fine in my uni network (and it has quite a few dark spots), all of my friend's networks but it intermittingly fails to reconnect to my home wlan. I have a sky router (sagem actually).

I have seen this on various routers before and encountered it again last night.
There is a discussion on the cause here:
http://forum.xda-developers.com/showthread.php?t=839367&highlight=connect+wifi&page=3
It is due to the lease expiring from the access point and the device requesting the old IP with first sending a discovery message.
One work around - not the best - is to reboot the router. Then the Tab seems able to connect. Also I think if you connect ofter to the router you might not see this as the device will ask for a new lease.
Another - from the above referenced post - is to create a DHCP reservation for the Tab. This will ensure it gets the same IP address every time. I made this change to my router - so we will see.
Hope this helps.

Samsung Galaxy tab won't connect to WEP wireless
I am trying to get my Galaxy tab to connect to my HTC HD2 that is set up as a wi-fi hotspot.
My galaxy tab will connect to all WPA/WP2 networks but not the WEP. Please help.

mine does the same on a SMC Gateway (SMC8014WN) aswell as a D-Link Router (DIR-665)

I am going nuts here because of the same problem. Tab worked flawlessly for the last 4 months, found any router and had no wifi problems until recently. I have a D-Link DGL-4500 gaming router, and my dsl modem router also has a wifi connection. I suspect from the new firmware. Mine is a Euro model. I dont know why I upgraded from JK5 to JMG stock firmware, and wifi issues started. D-link's logs reports that it receives a deauth from the device and the connection ends... and never revives. Sometimes it happens 3-4 times in an hour, sometimes it stays connected for hours. I tried everything, static IP, delete dhcp list, etc. I have reset the device twice to factory defaults. Even then it disconnected the first minute I turned it on and set the wifi. So it should be a firmware issue. I realize that the wifi signal is also weaker now compared to the previous firmware. Congrats SAMSUNG! The Tab is consuming my data plan even when I am home. And I wonder how wifi only Tab is going to handle this problem. DOES ANYONE KNOW IF WE CAN DOWNGRADE FROM JMG?? Help is appreciated.

my tab does the same thing (so does my x10). But when I open my browser, or anything that needs wifi, it reconnects automatically, however the browser usually needs to be refreshed (retry).

exactly the same behaviour. Every morning, I'm connected to my router but nothing works. Turn-OFF->ON and it works again

I should have noticed Roto's entering line. See: http://forum.xda-developers.com/showthread.php?t=939360.
Since JMG has wifi isuues, I jumped onto JMI !

[Q] Any Issues with WiFi

Loving the phone really, one thing i have noticed is when ever im downloading or uploading large files through my home WIFI after a short period the phone disconnects from the network and i have to reconnect manually. Any ideas is anyone else having the same issue. All my other devices are fine

Same thing here, but it reconnects itself - just losing the connection for 1-2 seconds. It happens sometimes even when browsing the web. Most likely some kind of software bug.

Had similar symptoms when playing with the phone at work`s WiFi (1st day of usage). On my home WiFi nothing wrong at all.

Make sure that keep WiFi on during sleep is always.
Or the WiFi will turn off the moment u turn the screen off

I found that WiFi is one of the most power draining things on phones. The best thing would be to switch to mobile data while sleeping and turn wifi off during that time.
That way you can still receive everything, but since you're sleeping you will barely use any data at all.
To bad the phone can't do that automatically.

I'm getting frequent wifi drops in my home (netgear router, wpa psk security) and its also affecting other devices in the house! Other wifi networks I've connected to seem to be fine, no issues whatsoever. Sometimes it'll say its connected, but no data, other times it will disconnect entirely.
This is a VERY strange problem and the fact that its affecting the wifi connection to other devices is even stranger.

Just an update on this, I returned my phone to P4U this morning as the wifi thing was annoying me and the phone has eaten 823mb of mobile data in one weekend even though i had mobile data turned off and connected to WIFI, The handset said i used 115mb and Voda said 823mb. not the only reason i returned it but it needed changing. So got my new handset up and running this afternoon and im set up and i been downloading all my files and apps with out any problems.
So looks like i had a dud phone first time around.

Getting the same problem too. All my other devices (Nexus7, Ipad, PC) can connect fine to my wireless home network (fibre). But when I start connecting my Xperia Z to the wireless network, after 5 mins, my Gateway will hang, and restart itself. Happens all the time without fail as long as I have my phone hooked up to the wireless network.
Anyone else facing this problem?? I'm kinda at a loss now on how to solve it. Tried adjusting settings on my wireless channel too but doesn't seem to help. Any help will be greatly appreciated!!!

Ok, so i reckon this could be an issue with not having a static I.P address. Gonna change it tonight when I get home and see if the problem is solved. It's either that or it may be trying to connect to a port thats used for something else? Have ports assigned for my Xbox ect. I'm not too knowledgeable about these things so any other suggestions are welcome. Not too many settings on the phone unfortunately so the problem has to be solved using the router I'd say.

I have static ip set up since the beginning, and I also have the problems. Only my problem seems to stem from 2.4 GHz/ 5 GHz (if this is even possible). 5 GHz is the preferred one, but this one seems to be out of range sometimes and it switches to mobile data. The 5 GHz is then out of range, while the 2.4 GHz is not. Very strange.

Ive found the Xperia Z has held on to a 5GHz Wi-Fi signal better than any other device I've used before, but the 2.4GHz can often disappear...
Very odd, although at home I am quite happy that 5GHz works better as there's far less interference from local neighbours. Perhaps that's causing the problem - in that the XZ isn't so well set up to cope with other routers on the same Wi-Fi channels??

The reach of my 2.4 GHz is at 75%, while 5 GHz is at 50%??? Strange.

I would always expect 2.4GHz to carry further, and so I am surprised by my experience too.
In my case, there's only 1 5GHz router visible other than mine, but countless 2.4GHz ones. Not sure why that would make the XZ drop (and sometimes even lose) the connection - but that's what seems to be happening.

Xperia Z no wi-fi without SIM
I have a different wi-fi issue with my Xperia Z. It does not connect to my home wi-fi when there is no SIM in the phone. It just says that the network is out of reach. When I pop in the SIM card, it connects automatically. Actually, all the hi-end Sony phones I tried recently do this (Ion, T and more). I've been looking for a solution here on the forum, but didn't find any helpful topic. But maybe I was looking wrong. Does anyone know, what to do?

I think the obvious answer is put a SIM in there... and if that means getting any old SIM and cutting it to size, even if it's not registered on any network, then do that.
I wonder if it the phone is looking at the SIM to identify the country, and therefore what channels can be used? I say this because when I first used the phone (without SIM) I also had problems [router not showing up in a scan], and my router is on channel 13. I then put in a SIM and at some stage did another scan and it found my router.
Is your router perhaps on channel 11, 12 or 13?
I know it's a long shot, but who knows?

Interesting point, will try to investigate with the channels. And I may also try to dig out some inactive SIM, thanks for the tip... The only thing I found is, that the problem obviously appears only with the WPA2-PSK security. With WPA, its all a-OK...

If you look inside the build.prop
The wifi.channel is not assigned,maybe this can gives you an idea guys.

I called Moto and after dealing with their terrible level 1 support I got the following:
HERE ARE THE INSTRUCTIONS FOR DOING THE WIPE CACHE PARTITION:
This will remove any temporary files that may be causing the problem, but will not delete your files or settings.
1. With the phone powered off, press the VOL DOWN KEY for 2-3 seconds then POWER key then release.
2. The device will display different BOOT OPTIONS
3. Use the VOL DOWN Key to SCROLL to Recovery and VOL UP Key to select
Tip: If the device reboots, you may have waited to long to make a selection, you will need to begin the process again.
4. The device will display the Motorola logo and then the Android in distress ( logo with Exclamation mark)
5. Press and hold the VOL UP key for 10-15 seconds. While still holding the VOL UP key tap and release the POWER key
Tip: You can try this step, holding the phone in landscape. If you are stuck on step 6, try a force reboot by pressing the Power key and Vol Down key, and start the process again.
6. The device will display additional menu options (Text will appear in BLUE)
7. Use the VOL DOWN Key to scroll to wipe cache partition and the POWER Key to select this option
8. The device will then perform the partition wipe
9. The device will reboot and start the normal power up sequence
Ever since it hasn't had any problems, but it's only been a few hours as well.

The issues started happening again...turned off wifi and everything resynced perfectly...

If it doesn't work properly with a different router try exchanging it. Also have you gone into advanced WiFi settings and forced the moto x to 2.4 GHz? If give that a try.

The force to 2.4ghz actually made the problem occur a lot faster, any reason it might be due to the massive amount of wifi networks around? When I set to scan 5 ghz there was only one still open, I might go into my router and see if I can change the atenna settings.
EDIT: Turns out if I go to 5 ghz my computer can't connect, but I changed the channel to something less populated in the area to see if that helps.
DOUBLE EDIT: It appears to occur after I'm supposed to get a Facebook notification, at that point I don't get any more notifications....attempting to clear out facebook data and cache to see if that does anything

Hey guys I'm having a similar issue with my moto x on the 2.4ghz band. Speeds are very slow and sometimes cut out completely. Im getting a download speed of about 300kb/s on 2.4 both on auto channel and it doesn't rlly change once I change it manually to an open channel using WiFi analyzer app. My download speeds on 5ghz hit 4000kb/s even with a much lower signal strength.
YouTube and Netflix is unusable and growing the internet sucks. I usually just use the 4g network while at home cuz its a thousand times faster but I'd like this to be fixed regardless. Has anyone found a solution or explanation?

I'm having these issues too. Got the GSM Developer Edition on 11/29. It immediately updated to Kit Kat OTA so I'm not sure whether it had the issue prior to Kit Kat or not. This only happens on 2.4 ghz wifi and only with one of my routers at home, a Netgear WNDR3700v2 running OpenWrt Attitude Adjustment (I tried upgrading from Backfire to see if it would help, it did not). The other router is a Linksys WRT350N and when the phone is connected to that one the problem does not happen. Note, that there are 2 laptops, a Samsung Galaxy S2, and a Kindle Fire HDX that have zero problems with the WNDR3700. All can transfer data perfectly fine and at high speeds. Thus I do not think the router is bad. Have not checked work routers. 5 ghz wifi is totally fine and indeed very good with this phone.
For me, the problem is that the phone seems unable to receive data at high speed (over 1Mbps) on 2.4 ghz wifi in any area where the signal isn't perfect and sometimes even in the same room as the router (although usually it is fine there). Oddly in many cases when it has trouble receiving it can send data much faster. It almost seems like it might be some kind of interference as it is rather random.
At this point I'm wondering if the phone has a defective 2.4ghz subsystem, though that seem unlikely due to good transfer with the WRT350N, or if this is some kind of wifi tuning software bug in the phone.
Any info would be appreciated. Does anyone have this issue who did not have the issue on Jellybean? Am wondering if anything changed with wifi for the update? Note, I have tried clearing the cache in recovery as noted in another thread with no luck. Anyone have the WCNSS_qcom_cfg.ini file from Jellybean for this phone? Would rather not reflash just for 1 file.
Thanks.

For what it's worth I have this same Netgear router and have had the same connectivity issues on both 4.2.2 and 4.4.
I did some reading today and found a couple possible fixes I plan on trying out. First one is to disable WMM. Secondly I found on the official netgear forums that they have had major issues (some of which you've described) with all firmwares ending in the .30s and went so far as to pull them from their download section.
My router was running firmware .36 and I successfully downgraded it to the latest stable firmware .12 that netgear now recommends.
Hopefully 1 of those 2 fixes improves the performance, at any rate I really think it's something with the router itself and not the moto x.

Thanks for letting me know this was also an issue on 4.2.2. Saves me the trouble of flashing back just to test.
I will be interested to know if your using official netgear 1.0.0.12 firmware fixes the issue for you. I haven't actually ever used the official firmware as I've run OpenWRT since I got the router a year or two ago. 10.03.1 had the issue, and it appears 12.09 does as well. I may try a trunk build at some point to see if that changes anything.
I had previously written that all was well on the 5 ghz band. This appears to not be 100% correct. Yesterday evening and this morning I found myself "connected" to the 5ghz band without actually having working internet. Toggle wifi on/off fixes it, but I shouldn't have to do it.
Not sure if this helps, but on the 2.4 ghz side things do work better on one side of the house vs the other. Also it seems that I can get a very fast connection at times and then it stumbles and gets stuck going under 1 Mbps. I still suspect either a defect or some kind of low level radio issues with the moto or the router regarding interference from neighboring wifi access points (there are a lot around me, single family houses on small lots). However, keep in mind no other device has these issues but the moto. In the rare instance I venture into a bad signal pocket the signal indicator goes down and speed slows or they lose connection vs the moto where it can show excellent signal and have no/nearly no connectivity.
I haven't tried it for long, but switching to wireless g mode vs ng may improve stability though I only briefly tried it. I did walk around part of my house checking the Mbps with the app "WiFi Speed Test" and while way slower than N mode it was far more stable. Even if this does work it is a definate downgrade in speed though.

Well its only been a day or two so it may be too early to tell, but so far my wifi seems much better after making those two fixes I mentioned above. This is on 2.4 band, the 5ghz band doesn't provide me enough signal strength to use all the time (router is too far from my bedroom).
The main issue I was having was my wifi signal would cut out even though it still showed a good connection. I could swipe down on the status bar and see no download arrow next to the wifi icon so I knew I wasn't receiving data. However a simple disconnect and reconnect to my wifi would fix the problem until it happened again. This seemed to be most common while watching YouTube videos, in fact it happened far too often which is why I went searching for a solution.
So as I mentioned things seem to be better for sure so far but I need to give it a week or so to see how much it is really helped, but so far I can't remember any wifi cutting out since I've made those two fixes.

It helps I think.
My understanding is that this is the level when the phone decides that wifi is too weak and it should switch to a data signal.
I don’t suffer from range issues – the SP has as good, if not better range than all the other wireless devices in my house. However connecting in the first place can be a right pain.
I had an xperia ray before and it also did what I’m about to describe (but connected more reliably) – in essence when wifi is ‘connecting’ the signal strength will go from excellent/good/fair to poor or even nothing. It fails to connect and I’m told there’s an authentication issue.
This tells me that either my router reduces its wifi signal, or my phone is less able to receive the signal during this stage. As my router is old (6/7 years), I’m inclined to think it’s the router – Sony probably test their devices on more recent hardware.
With these things in mind what this tweak does, is hold on to the wifi signal for longer before switching to a data connection, making connecting to wifi more likely.
In my case after applying this hack the signal still drops whilst ‘connecting/authenticating’ but connects more frequently, and the signal goes back up again once connection is made.
I must also say that wifi problems are not unique to Sony devices and having had a look elsewhere for a solution I discovered that many other phones, from a variety of manufacturers, have similar issues. One of the big US Universities even wrote reports about how the Android OS was at fault for overloading their wireless network with repeated DHCP requests.
Anyway before you apply the tweak try enabling ‘auto IP support’ in advanced wireless settings. Similarly it doesn’t make sense to have ‘avoid poor connections’ enabled.

It does work for me

Thanks for the answers. I have been testing this fix and i can say it works for me. Where i had 1 weak signal now i have 2 or 1 but a steady one. Now i can move in my house without losing WiFi.
Remember that you can change -100 and test it with more (-300) but I supouse the battery will last less. Otherwise you can change to -90 or -95 if you think WiFi its enough good.

Very good. Saw significant improvement in the areas of the house that I had a problem with the connection before. C5303 on 12.0.A.1.257.
Thanks

Wifi problems or not? People without problems welcome :D

Hello all together,
I'm considering to buy this phone (actually for quite some time ). Apart from the OnePlus service (which should not be part of this thread right now) what bothers me most are the Wifi problems I am reading about.
Problem is, when reading throgh the internet, you never known whether all or only the people with problems are speaking up.
So maybe to lower mine and the doubts of others, people owning this phone could quickly post wether they do experience wifi problems or not.
Thanks in advance

My OP3T did have some major wifi issues when I first got it. Regardless of whether I connected it to my router's 2.4 Ghz or 5 Ghz bands, it would momentarily disconnect every few minutes and then reconnect within seconds. It wasn't a major issue for most tasks, though some games that required a constant internet connection did get interrupted. Oddly, the wifi worked flawlessly on my school's network, so I'm assuming the issue is router dependent.
Then OOS 4.0.3 was released a few weeks ago, and with it the "disable IPv6" option. I had read that IPv6 did cause some problems with older routers, but I couldn't force it off on mine. Enabling the disable option on the phone seems to have cured it of all its disconnect problems. It's working consistently now.

No problems at all.
Ever

Please report back. Would be interesting if this is some kind of definite fix

i have not used the Stock OOS Rom Was using this phone from like a month and running with custom roms tried many and i have not seen any wifi issues

I've had the one plus 3t since December and I have never had any wifi issues. I've used stock OOS and Los and wifi has always been great for me

Hello,
I'm having no problems with the WiFi, no problems at all. But I do have a problem with cellular data, it randomly turns off in the middle of a YouTube video or while browsing social media. I'm hoping they fix this in the future.
Cheers!

Wifi is pretty good... when you're sitting next to the router...
I get about 60mbits down when I'm next to the router and about 1mbit when I'm in my room. My oneplus one, my dads iPhone, my laptop and my shield tv do not have this issue.
It seems like the Wifi range is absolute crap which is really the only thing I don't like about this phone.

Thanks for the answers so far. Not as bad as I thought

I heard about the lack of speed but this is by far the slowest I read about

I just got my 3T two weeks ago. It came with Marshmellow and I immediately upgraded to OOS 4.0.3.
I am connected to a 5.GHz WiFi connection in my house and never had any problems.
I don't play games on my phone so I can't really test gaming.
I am Systemless Rooted with Magisk with a pass for SafatyNet, meaning I should be able to use mobile payments but I have yet to try.
I doubt the fact that I am rooted is making a difference in terms of my WiFi connectivity.
I can test my 2.4Ghz connection in the future. I have not done anything with IPv6 or modified anything in regards to my WiFi settings to make things better. I simply connected my phone to my 5GHz network and started downloaded apps and etc.
I hope this helps.

Didn't have any issues yet. The only thing I agree on is the poor WiFi range. I had exactly zero inhouse issues neither with my iPhone 6s plus nor with my nexus 6p. But with my oneplus, I loose connection in my kitchen, which is like 10 meters far from my router. Pretty afraid of this being persistent.

Same here

Thanks again for all the answers .
I think suppose there are definitely a lot of people without any problem concerning wifi connection drops.
The thing with the poor connection is definitely something but that I already knew.

No wifi issue for me.. Stock OOS 4.0.3 rooted

As far as I know it doesn't necessarily connected with the problems in the android device. My causing is using the same phone and as I remember he used to face some issues but later he found out that the phone works well, but he has issues in the wi-fi router he is using. To avoid this kind of problem I would like to recommend you to get acquainted with the following article 192.168.l.l login . Hope it will be helpful for you!
