I have a Samsung Galaxy S Vibrant device and a strange Wi-Fi connection problem.
It seems that the WiFi conneciton is being lost intermitently with no apparent reason. I ping the device, most of the time there is a 'Request timed out' and only sometimes a 'Reply from <address>'.
On the device side the connection behaves erratically as well, sometimes there is connection but most of the times there isn't. The strange thing is that under device's Settings->Wireless and network->wi-Fi settings the connection's status is "Connected" all of the time, signal strength is excellent, link speed is 54Mbps.
I had this issue on a native 2.1 Samsung Galaxy S Vibrant install, then decided to flash a custom 2.2 ROM hoping to end the mistery. The new custom ROM is an Axura21VE.zip and the WiFi connection problem is exaclty the same as before.
Does anyone have the same WIFi issue as I have? And yes, I did a search before posting this. In fact, I searched for several weeks and saw many SGS Wi-Fi problems being reported but either they are different or they are similar to mine with no solution. Since I need a stable Internet connection on the device for app development, next logical step would be looking at reverse USB tethering. Yet decided to post here before giving up on Wi-Fi.
For the record, the Wi-Fi acces point is under my control, i have a ASUS P5B-MX/WiFi i946GZ motherboard, windows XP sp3. I tried, I think,
every possible combination of Wi-Fi settings available. The only client device I have at home is SGS. At the office network, SGS is having the same
Wi-Fi issues, while a HTC Desire and many laptops don't.
here is what I just found out: if I do a constant ping form the device to google.com for example, then the conenciton is maintained all right. So, should I constantly ping something to maintain a decent connection? Is there a setting or something in Android OS I am missing?
I had this exact problem - changed my router and it works perfect now. Really weird and not an ideal solution but worked for me so far (touch wood!). Try playing about with your wifi config maybe, change encryption, channel etc. Good luck.
Hi, I'm having the same problem on my Galaxy S i9000 on Darkyy's v7.8. I never used to have this problem until I flashed the second to last release. The device says I'm connected to the network but I can't get any internet access. I tried reflashing my official firmware DXJPA, but I still no joy. I'm not really sure what to do.
YES... i have been searching for days. I feel I may have a similar issue. im connected, speed good, IP there.. no data, browser just hangs. seems to happen less in stock. (Rogers captivate, P10.1) also WiFi manager reads my WiFi channel off by 2!! so im set to use ch 9 on the router and WiFi manager on the captivate says its broadcasting on ch 7?? any ideas? ping to infinity??
side note: this happens on all routers and all roms. other galaxys on my network read proper ch... GF's Iphone see the right channel?? HELP..
I'm also having these problems, reposting my reply from another forum:
Just wanted to chime in that I am also having these problems with my samsung vibrant. Seems to only happen from my work router but happens very consistently. Wifi will work immediately after setting it up but after a short time period will stop working completely. It will say it is still on wifi but will in fact have no access to the local network or the internet. Stopping/restarting the wifi connection doesn't fix it. The router has to be manually 'forgotten' and then re-added for it to begin working again. (Update: sometimes this does not work either, in fact).
This is with a 2wire modem (standard issue by at&t) using WEP security in 802.11b/g mode.
Some people recommended switching from 201.11b/g to pure 201.11g. I tried this with no luck. It was also recommended to try to app 'wifi fixer'. This also did nothing to solve the problem. Given that it is my work router, I don't want to go changing the encryption and other crazy things as I'm not the only person using this router and it would break the connection for others.
MRSizzle in another thread (which xda isn't allowing my to link to) seemed to accurately describe the problem as such:
"It appears to be a driver issue with the Samsung base OS drivers in the phone. Possibly sleep policy is not operating correctly and the wifi radio is being disabled by the hardware and is not being controlled correctly by the software so the WiFI icon still appeers to indicate the phone is connected. Also the wifi signal is not being correctly reported. the signal appears to be attenuated more than it really is."
This description would line up with the OP's reports that repeated pinging will keep the connection alive.

ASK DARKY its his rom and will know more .

Anyone figure this out? I'm trying to use the Web Desktop app but can't because I can't even establish a connection with my phone!
Hi friends,
I have similar problem, but at first I easilly connected to Internet, but now I can connect to my WI-FI but no internet connection. I am not sure but maybe this has occur after updating to Android 2.2.
Any suggestion?
Thanks in advance.
explanation and apology
I was wrong in my assumption that it's an Android device problem. The problem was in the Asus motherboards embedded Wi-Fi access point. I bought a separate Wi-Fi router and now everything works like a charm.
Hi folks
Since I updated to JellyBean (JellyMod currently) I have an issue with my wifi connection.
It shows connected but i cant transfer any data (every app fails to establish a connection) until I turn off the wifi and turn it on again. then it ill work for some time and fails again after a not defined period of time.
I found a lot of threads regarding similiar problems but I did not find a solution yet (and for me having a rooted phone installing an app that that runs in background like wifi fixer is a workaround, not a fix
I already did a complete factory reset and fresh install of jellymod.
My router at home is a netgear wndr3700 with the latest dd-wrt. all my other devices work great.
I set the wifi of my i9070 to always on. also i installed auto wifi for location based wifi on/off-profiles.
all of this worked with gingerbread, never had problems...
any idea? seems like a lot of galaxy phones and even tabs are affected...
Thanks in advance!
Hi All, I've searched around and can't find threads that are exactly what I'm experience, so I'm hoping this is something the community can help with. I've been experiencing this problem since flashing CM11 a few months ago. My wifi has no problem searching and connecting, but intermittently while on wifi, I'll notice that I'll only send data and not receive it. Waiting 15-30 seconds will usually have it come back, or disabling/enabling will also fix it, but it's never consistent. I notice when the phone is plugged in, the wifi connection stays pretty good.
Just to clarify, I am not losing the wifi signal and the phone stays connected to the network. This happens in all kinds of wifi (whether home or work). Any help would be appreciated!

I dont know if its the same in CM11 but in stock rom you have some wifi options to reduce battery usage, maybe turning them off could help? If not you should make a nandroid baclup of your current setup and flash another rom temporarily to see if the issue persist. Btw are you using a stable build of CM11 or nightly builds? If you are using nightlty builds, you might want to try with a stable version.
Is this always happening when using routers of the same brand? I already had this kind of issue but it was with my One X not my M7. The only way I was able to use the wifi without making the routers hang (every d-link router) was to turn off the N band (5Ghz) and only use the 2.4 Ghz bands (a/b/g). Maybe it worth a try... but I never heard of this issue for the M7.

I tried the Wifi optimization option and it's the same performance. I'm using a stable build of CM11 and wanted to see if there's something I'm missing before flashing again.
I'ts a little bit difficult to tell which routers this happens with, as I can recall only having consistent wifi traffic once in the past 3-4 months. I've switched back and forth between 2.4ghz and 5ghz on my home router to the same issue as well.
Thanks for the suggestions...may just have to resort to a new ROM...
Has anybody had any problems with their WiFi not connecting? My device seems to fail to connect to wifi after a couple of days and just sits trying to connect. Toggling WiFi doesn't seem to resolve it, and I have to reboot the entire phone to get it back online.
No problem here.
Connects very quickly, never seen it fail to connect, even on my works dodgy BT homehub 3, which used to tie my old Z3 compact up in knots..
Yep.I thought that Snapdragon 835 cause this problem. Xi oami 6., ZTE z17 and Op5 had the same question with WI-FI connection.

I have a sd835 s8 and I haven't had any wifi issues whatsoever since launch. It's a sample size of 1, but I don't know if it's truly due to the sd835
I haven't had any WiFi issues. In fact my WiFi connections have improved using the XZ1 compact over the X performance (the X performance dropped its WiFi connections 3 times during my data transfer to the new phone)
I've had my XZ1c for about a week now (European model) and it connects to my home network (5G) normally. Signal strength is fine, although the galaxyS6 it replaced definitely had superior reception. I do have wifi issues, but only when already connected to the network. When the phone is asleep (screenlocked) it seems to lose an active connection. The wifi connection should be on at all times, even asleep. It will show the wifi symbol, but data apps don't load, and it will have lost the connection as remote for spotify connect (playing on my reciever). It will also switch to mobile data at random times with normal wifi signal strength (even though I toggled this function off in the developper settings).
I'm not sure if this is something that can be fixed through system updates. I haven't seen any forum posts with similar problems though, so I'll try to document what is actually happening before I contact Sony support.
I bought the US version and flashed the UK firmware to get the fingerprint reader to work. No issues whatsoever with this phone. No Wi-Fi issues, overheating, signal strength, battery, nothing. Everything works just perfectly.
Same issue here. Mine is Europe (NL) version. The upload and download speed can be very unstable. And especially when I take it a bit far way, even you see that it's connect to the wifi with full signal strength, it said internet is unavailable.
I'm not sure if this related to the system update of last weekend or not.
Further to my issue. My phone will drop wifi connection and repeatedly try and connect - it usually cannot see any other networks at the time. Restarting the wifi on the phone, or rebooting the access point do not help. Running a packet sniffer on the LAN shows no activity, which indicates the issue is to do with wireless handshaking.
The problem occurs every few days and the only way to resolve it is to reboot the phone, which fixes it instantly.
I contacted Sony and they told me to do a complete reset on the phone, this didn't work. I updated my findings and pointed out that it's seems to be a firmware compatibility issue. Of course, you only get to talk to first line, and as a reset didn't work, they want me to send it off for a warranty repair (which of course will be returned with "no fault found" as no doubt their wifi will be different enough for it not to have been picked up on day 1 testing).
I'm currently trying to gather a bit more information on the fault, e.g. does it only happen on my home wifi etc. I've disabled channel bonding but that didn't help, and I've not jiggled my DHCP settings after seeing plenty of posts describing wifi problems on Oreo for other phones.
It doesn't happen frequently enough and I don't have the time to delve deeply into the network to identify the cause.
One interesting thing was that it went funny at home, but it was working when I got to work. When I got home it still couldn't connect. So I suspect it's to do with a particular compatibility issue somewhere.
no problem here conecting to 5 and 2.4 wifis...

I haven't gotten around to this yet. Do you still have wifi calling and volte available?

So far my wifi has been fine...
Mine is worst, i couldnt get it to connect at all but all my other device including xperia xa, xzp, laptop, Ps4 PS3, everything connect without any issue whatsoever, already excahnged once and still the same.
Think mine is struggling with either a single access point or VLANs. I need to dig further, but that requires buying a new AP - this phone is getting more and more expensive!
exactly same issue as Dashers describes with my XZ1c. I am not watching it closely, but it seems that it is hapenning after around 2 days online. Never happened before on same network with my previous Z3c, which had run months without restart and any problems whatsoever (till its display died

I have more or less the same issues, and a reboot always solves it. It happens with both routers form ASUS and Draytek.
Additionally I see issues with Spotify connect dropping or not being found on my Sonos (hardwired to LAN), but not so much to Chrome Cast Audio on the same network.
I don't have a problem connecting to wifi, but I seem to have a different issue. Even though wifi scanning is toggled off in settings, my phone still seems to be scanning according to Battery Historian. I think this is one of several things contributing to my high idle drain. Does anyone else have this problem?

Have you turned wifi scanning off ?
settings\Lock screen & security\Location\Scanning - turn wifi scanning off

Yes, wifi and BT scanning are both turned off in settings and have been since the beginning, but both seem to be happening anyway according to Google's Battery Historian tool. When I go back in to see if they've been toggled on by an app or something, they still appear to be off.

I have this exact problem. One second its 100% signal and is workin as expected. The other second it just drops and tries to reconnect like crazy. I have even had moments when i am unable to find my wifi after said disconnect. All my other devices is working like normal on my wifi. Using Asus n66u 5ghz.
I have been having the same issues as mentioned above with my XZ1 compact(european). My issues with dropping wifi signal seems to be happening when there are two different wifi signals to choose from. They are both on my local network. One is an extender due to the size of my house. When it can detect both signals, it can't make a decision on which one to choose. Once I remove a device(forget wifi device), it stays connected to the other with no problem. Since it isn't trying to compete with the other.
Has there been any improvement on this issue?
My wifi keeps dropping as well, it's getting to the point where I might return to Samsung unless it's fixed in a firmware update!

here does the wifi issue happen? just at home? on public wifis as well? work wifi? is your vpn turned on? thats a common thing that causes issues.

Same problem started to happen recently with my phone but only with 5GHz WiFi.
Getting the same problem with 5ghz as well, have to shut it off and then reconnect to the router. Their networking coding is a disgrace, tons of complaints about it all over the place and Samsung does nothing.... I can't return my device but if you're still within the period of being able to, I would if I were you. I absolutely hate this device and all its problems.
I"m having a similar issue. First I noticed that LTE would stop working until I rebooted. Then the wifi would glitch up the same way. I'm not sure if it's the switch from one to the other, or what the deal is. The worst part is it's not repeatable. It just seems to do it randomly.
I have encountered the same problem with wifi dropping. I went to wifi setting and forget network and reboot. Punch the password back. Its working fine now. By the way im using the latest s10+ firmware rooted
Hi guys,
I was faced to the same issue since I bought my S10e. DO not mind the solutions proposed on generic sites (thecellguide.com, thedroidguy.com), they're garbage, totally irrelevant (reboot your phone, erase your cache blabla).
I've tried several hypothesis to troubleshoot this issue (very inconsistent wifi connection with my TPLink 4G routeur MR600, disconnecting every minute or so). In fact, tens...
And the final word seems to be, as observed by other users: 5GHz. After disabeling the option on my routeur (switching all traffic to 2,4GHz) everything is fine. For now.
Good luck
Chris (Fr)
I've also had this issue on the S10E where the wifi would be connected but no internet. After a few minutes it would no longer see the wifi. 5ghz of course. 2.4 no problem. I noticed this happened right after login to Samsung account. Now that I'm logged out Samsung account wifi is all good. I'm on the oneui 2 Jan sec update.
I have the same problem with my girlfriend's Samsung S10, it keeps disconnecting from 5GHz. Just now I switched her to 2.4GHz to see if it solves the problem. All our other devices (HTC One M9, 2x laptops, raspbbery pi 3, chromecast, google home) have no problem with the WiFi on either band.
Samsung really has a problem with it's network code, I also had a problem at work with Cisco APs when an Apple device and the Samsung S10 where on the same network it would bring the whole network down. It was some multicast bug where the Apple would announce itself as the gateway only when an S10 was present.
It's happened to me but never until after the last update. I noticed yesterday I was connected with no internet.
