Wi-Fi Disconnected~

Running CM3.6.5 and cannot get the wifi to work. When I turn it on after a few seconds it says "Disconnected" right underneath it.
On the wifi networks I try to connect to my home router but it doesn't do anything. the signal strength:excellent securitypen, i hit the connect button but nothing.
I've turned off and on the wifi with no luck. Been searching for help but can't find any. If this has happened to you and you've fixed it let me know how i can do this.
Thanks!~

Have you only had this problem on one network? At work, every few days I loose my connection to our Linksys. A coworker's iPhone also fails to connect, but another coworker's Dell laptop can connect fine. Watching logcat I can see it attempting to connect, then spitting out an authentication failure error.
Restarting the Linksys seems to solve the problem. Not sure what is special about the two phones that makes everything crap out.

the only wifi network i use is my home one right now. haven't thought about restarting it. gonna do it and hopefully that will be the fix i've overlooked ><

/slaps his forehead.....
restarted my router and that fixed the problem. for some reason i've never had to do this but now i know.
thanks for the post! wifi working now.

Glad that helped. I'm still a little stumped about why it's doing this, but it sounds like we have the same issue. Restarting the router is easy enough though.
Now at home, I have a Linksys running Tomato firmware, and it never boots either of the two G1s we have. So it's just the stock router firmware for me, and it only affects G1s and iPhones (or at least, it affects them and not a laptop with Intel wireless).

i am having the same issue. does anybody knows if its a rom problem? I am running cyanogen 4.3.1. in college, where my laptop can connect fine, the g1 can not, and has a very low signal level while laptop shows excellent.

[Q] Wi-Fi Woes

Ok I have a very iritating problem.
My captivate works amazing in all ways... except one. When I'm at home connected to Wifi, within a few mins of me putting the phone down, or even mid use, the wifi will just stop working. The icon still shows it to be connected however no apps are able to actually get internet. A quick pulldown of the quick access menu and tapping wifi off and back on again gets it going great... for another 5 mins. Then the same thing happens.
Its been like this ever since I got the phone, even after flashing different roms. Now i'm running a Linksys Wireless - N router - maybe they're not playing nice?
I dont think its a hardware fault because when I serve wifi, IE the captivate is an infrastructure mode access point for 3g, it stays on consistently and my laptop can tether for 2 hours or more.
Anyone know what might be causing this?
Thanks

When you have wifi on, go to menu settings and 'Wireless and network'. In Wi-Fi settings you can change the Wi-Fi timeout.

Try goin to settings->wireless and networks-> wifi settings (menu key)advanced and set the sleeping policy to never

I've done that...
i *Think* i've fixed it. I was using WPA2 IPK encryption or whatever.. Switched back to the 64 bit crappy WEP. Wifi was on all night and all morning with no cut out.
Might be just another linksys-is-crap situation.

HI, I figured I keep my wifi woes within a singe thread so.
I have an old D Link WBS 2310 router.
I recently got a message from AT&T that I'm near my data limit. This surprised me as my last cycle I barely got near 500mb. Since my bill isn't ready yet, I can't see exactly what it is I'm doing to use so much data.
TO be safe I figured I'd pull out my old router and set it up. After hours of hassle getting it to work on my new computer, I wasn't able to get my Captivate to hook up to it.
My laptop works fine. It gets a fast wifi signal, but my phone just says "Obtaining IP address" for a while and then gives up.
My phone gets wifi at work, at friends', at coffee shops - but not at home.
I've tried this with no encryption, WEP encryption and WPA2 encryption.
Each time my laptop would hook up to the wifi but my phone wouldn't.
I searched some other forums and found similar problems with HTC phones.
Some answers say that D Link sucks. But that answer applies to other brands as well.
Do I need "n" wifi, rather than "g"?
I don't want to buy another router only to find it still doesn't work.
Any help?

part of the IEEE 802.11n standard is backward compatibility with all previous 802.11 standards IIRC, so there should be no need to buy a new n device.
HOWEVER, i am also having issues with my wi-fi and my g capable router. i will meddle around with some phone and router settings to see if i can fix this, this is one area were i can actually be of some use on this forum

Hi. It turned out the wifi was broken on my captivate. I reset it to stock and it's all better. It had been working up to the previous day so I assumed that it was still working. The router goes down intermittently in general, so I've ordered a new one to see what's up.

Hi, I'm back! So after resetting the phone and getting wifi to actually connect (rather than being stuck searching for IP address), I'm now having the exact same problem is the OP. The OP seems to have solved this by switching to WEP. I tried this and it doesn't work. My timeout is set to never. Also, it's the same at home (I replaced my router) as well as at Starbucks and a friends house.
I'm connected, but can't download or sync. It works initially and then stops, and then comes back in briefly and then stops, all the while "connected." Sometimes I can fix it temporarily by turning off wifi and then turning it back on.
SO what's the deal? Is it a hardware problem? Is there some secret magic code?
edit: Just disabled encryption - same problem.

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] Anyone else having WiFi issues with their HTC One?

Hey guys,
So I just got my brand-spanking new HTC One today. I upgraded from the Evo LTE, and I already love it.
But there's one thing that has been really frustrating to me for the few hours I've owned this phone... It has major WiFi issues.
My One can see the WiFi network, can connect to it, but wont give an internet connection! It's so frustrating!
My Evo LTE, being connected to the same WiFi network, connects to the internet with no problem at all.
A temporary fix is to turn off the WiFi radio, then turn it back on. As a result, I would connect to the internet for a minute or so, then it would disconnect from the internet (it's still connected to my WiFi network, and it recognizes it, and it gives no messages about the connection suggesting that something is wrong with my router/connection).
I changed the frequency bands, but they all have the same issue. I have enabled "Best Wi-Fi performance" and "Keep Wi-Fi on during sleep."
I've also reseted my router numerous times... No luck.
Is anyone else having this issue, or did I just get a lemon? Can anyone think of a possible solution?
Thanks!

no issues here with my one and my netgear r6300 ac router.

Wi-Fi has been fantastic for me on my one. My evo LTE if you remember had the issue of wi-fi just shutting off after the phone was asleep. That was fixed in an update but even after that was fixed my evoLTE would show it's connected but data would not work. So I would have to toggle it on & off. I also had an issue with my sense widget not working and getting stuck. I was really starting to dislike the evoLTE because of it since your notifications quit working if your wi-fi was not connected correctly. I put up with crappy wi-fi for almost a year, mainly because I knew if I took it into Sprint they would say everything works perfect I just didn't wanna deal with. I know it's extremely frustrating to not have your wi-fi work correctly. My advice see if you can get a hold of another HTC one to test side by side. If it's a hardware issue you should get it swapped. You could also try hard resetting. I use a a WRT54GL with tomato at home and a Asus N66U at work, both have performed awesome with my one.

I have _exactly_ the same issue with my One. I have no idea if it's a software or a hardware problem. Tried a hard reset just yet, but it didn't seem to make a difference.
Really frustrating indeed, since the One is not very good available in the Netherlands yet, so if I return it, I might have to wait a few weeks to get a new one. I've tried it with at least 6 completely different WiFi networks, but the problem occurs with every one of them.

Only issue I have had with the WiFi thus far is it doesn't seem to have the pickup up range compared to my other phones and tablets.

WiFi on mine is insanely crazy! Picks up signal way better than any other device I've ever owned. Might be the kernel I'm running. Try it out! Look in the original dev thread.

I've noticed this as well. Areas in my office where I could get a decent wifi signal with my 3D I am dropping wifi completely with the One.

Router brand/model? Firmware version? WEP/WPA/Open? 2.4Ghz, 5Ghz or dual band? Channel (more relevant on 2.4 than 5)?
Does your phone get a valid IP? Check on the phone itself then the router under DHCP (assuming normal configuration, IP should begin 192.168.*.*)
Can you ping any internal node (ie your router) or external node (ie google.com or the IP to google)?
If your router has WEP/WPA enabled, switch it to Open solely for testing the connection.

Had the exact same problem. Only thing that fixed it was switching my router encryption from WPA to WEP. Works like a charm now. Best of luck.

Same problem and my solution
I had the same problem. Finally I tried to reset the phone without putting all my google-account info back. Then the wifi works fine. After that a Added my google-account and can enjoy my new HTC one. The phone is really good!
Note that in this way I didn't get all my setting back from my google account (like access points), but at it is working!

OMG, you saved my life. This was it!

WiFi speeds slow when Bluetooth is on !!

I know this has been discussed with other devices, but I have yet to see a solution, so I'll post here and am willing to try anything to resolve this issue.
I have tried all I could think of, clearing cache out, checking for conflicting devices, tried uninstalling some apps I think my be the culprit, rebooting the device, the router, and the Modem etc..... The problem still occurs, I'm not sure if this started since the 5.1 update or prior, all I can say I only noticed it a few days ago, when I decided to do a Speedtest, I know I have done Speedtest before, and never noticed this issue.
Once I'm connected to WiFi and my Bluetooth is turned on, my WiFi speeds are slow and bounce from 2Mb's to 5 Mb's, and when I say bounces the speeds go up and down during the process. As soon as I turn Bluetooth off the speeds are back above the 30 Mb's.
I have tried many of the recommendations around, but have yet to find a solution, Is it a LP issue ?? any other device I have connected I have no issues, I even have a back up Huawei, on LP, and have no issues when BT is turned on. Heck, even my wife's 1st Gen Moto X has no issues. Since I only realized this recently, today when I get to work I will try it when I get to work and see if it does the same on WiFi there when BT is turned on.
Any suggestions would be great.

Yes, same result.

Well I can tell you it's either a rogue app, causing it, or LP 5.1, It did the same at work today, so I know it's not the router issue

Change your router channel to something manual, lock it to one frequency. You can check a less congested channel with "WiFi analyzer" by "farproc"
It's the best one I know at least.
Both WiFi and Bluetooth do channel hopping, I've had this happen a lot at work where there's a ton of wireless devices nearby.
My bluetooth mouse will start to lag on my laptop and things like that, I guess both devices are attempting to hop channels and end up doing it at the same time, to the same band over and over causing this issue.
Wifi will grind to a halt on any devices connected to your router because wifi isn't really designed to switch channels often.
If you can upgrade to 5Ghz that will definitely solve your problem, but you have to go with a high end router that has some proper TX output at 5G.

I can switch to5GHZ, but from what I recall the range drops if I do so, also can BT be assigned a channel also, I guess this would help resolve the issue if this is the cause ?? If BT still hops, it will simply be a matter of time when it hops on the channel my router is set to ??
