wireless issues (intermittent)

anyone got weird intermittent wireless issues?
Every now on then, and then seemingly only on some apps, wireless network connectivity will come to a crawl and / or seemingly stop completely. Apps time out etc. but I know the network is fine as my flatmate's galaxy nexus / my laptop remain fine. The most common culprit is the play store. I turn off wireless and go on HSPA, wait a while, go back to wireless, all good.
Also, once I had to kill chrome beta to fix it.
What gives?

I am having some minor wifi issues too, but i think they are slightly different from wintermute's problem.
Both my wifes and my One X won't reconnect to our wifi after returning to the house. The only way I have been able to get them to re-connect is to reboot the router.
The One X's try to reconnect appear to, then instantly disconnect and just keep cycling. Turning the wifi off and on doesn't seem to help.
Our Asus transformer and the laptop don't seem to have any issues if taken out of wifi range and then moved back in.

Hi there's a few forum posts about this. A number of us has had this issue...the One X would not have good WiFi speeds, or would completely stop whereas all other WiFi enabled devices on the same network at the same time would be fine. A reboot of the router seems to fix this for most of us. Doesn't quite make sense why the One X would be affected by a wifi issue but not other devices, but seems to do the trick for most people. Its been 7 days now since I had my One X, and since rebooting the router, the wifi issues have not returned.

I'm a cisco tech in real life and trust me its not my wireless setup... proof is that all other droids work fine (my old nexus, atrix my flatmate's galaxy nexus etc.) unless there is some super esoteric setting that the HTC one requires
having said that I have rebooted my WAP a couple of times (in addition to tweaking my router a bit re: IOS firewall, some tcp-mss tweaks I was using etc.) and it does seem better. Still at a loss to understand why no other device has any issues except for this

I'm seeing wifi drop and reconnect all the time on my One X.
Signal strength isn't an issue, I'm sat 3m from the AP however their are lots of wifi networks in this building so could be an issue with interference...
I don't have any issues with my laptop or old Desire on this wifi..
I see the same issues at the office but again their are lots of wifi networks at that location too...

Hi there,
I had a problem with my HOX and my German Fritzbox Router...it would connect, but then not letting any data through...and then even disable the whole WiFi signal so that my laptop, ps3 and Samsung Tab did not get a connection anymore...reset of the Fritzbox was necessary....loads of HOX user reported the issue in a German forum, and one suggested to set the WLAN signal from b+g+n 2.4 to only b+g 2.4 and voila....problem has disappeared...price is that connex max at 54 Mbits now...but I can live with that...try it...maybe it solves some people's WiFi issues...until someone or HTC themselves figure out a working solution with a full wireless n support...

I am experiencing the same issues but with the one s, not the WIFI ones the actual network stops all of a sudden and usually within 1 minute comes back.
It happens about once a day.

The only real problem I have is with the WLAN stick which I use on my pc as hotspot. My Phone connects but after a few minutes I have to restart WLAN on phone so it works again. With the router at my parents home (Fritz-Box) I dont have this problem. I use connectify lite on my pc. With the built-in hotspot in windows 7 it just wont work out. Maybe someone else have this kind of issue and knows a solution.

I have the same problem at home and at work.
Disabling WiFi-N on the AP fixes the problem.
At the office we have Netgear WNAP210 and at home I have a Draytec Vigor 2710VDn

Can't quote xda app giving me invalid thread id error, but I have the same exact issue at work, the linksys wag120n router I use as wap, connected to a net gear router, most times when the phone disconnects, and only the hox, it takes down the internet for even those pcs connected directly to the net gear router, strangely I only need to reboot the linksys router to get things working again.... Weird.
I think the hox is doing something, like sending repeated dhcp requests (as in a bug on hox) and taking out the dhcp server. Although of course various routers would behave differently to this. My home network is fine. Not affected ever.

Galaxy Note 2 Wifi issue

This is pretty strange so I thought I'd check here with people.
I got my new Sprint Note 2 today. When I was at home it connected to my wifi network and worked fine. When I got to work I connected it to our wifi network and the internet won't work. If I turn off wifi internet comes back.
Here's the kicker, I have my old iPhone right next to it connected to the work wifi network and it is connected fine to the internet. This is definitely going through wifi as I no longer have a data plan on that phone.
I checked with our IT admin who said that there is no need to "accept" a device on our wifi network. He also rebooted the network for good measure. After both phones lost the network (from the reboot) and reconnected the same thing happened. No internet from my Note but internet works fine on the iPhone. Restarting my Note doesn't fix the problem.
Any ideas? Thanks.

I have the same problem. Need help too.

Is the wi-fi sleep mode on?

Very odd. I've had no such problem at home,work or university

My network admin created a second wifi network to connect to (I guess our router supported it) and when I connected to the new one I got internet.
If it helps others try and solve the issue he tried pinging the IP address that my phone was using and said that he could only send information but not get anything back.

Try changing your wifi channel config in the router.

Hi, I've got the International version N7100 and experiencing weird wifi problem. I have tried to reset my wifi router and use static IP but it doesn't solve the problem. Btw, the problem is whenever I connect my Note 2 to wifi it would lose connection after a while then messes my router and connection of my PC to router as well. Never had this issue until I brought the Note 2 home a week ago. I had to restart my router and turn off my wifi on Note 2 for everything else to work. My iPad, iPhone and PC are all doing fine when Note 2's wifi is off.

I used to have terrible problems with my Virgin Superhub which all went away when I changed the security settings to WEP hexidecimal from WPA2-PSK (AES). Laptops and phones would have intermittent connections all the time which a reboot or channel change would sort out but only temporarily. Give it a whirl.

I've been experiencing the same problem. It's especially annoying when I try to download big size apps on Google Play ( > 1 gb) because it will stop any moment and i will have to re-download it over and over again. It never happens when I connect to school wifi but it just happens when I connect to my wifi at home. Weird. Nothing is wrong with my wifi at all because my other computer is always connected 24/7 without any problem.

I have a similar problem on Omega Ron v5.0 with latest Andrei kernel. The phone gets stuck sometimes in getting IP address part or have disconnects. It's annoying.

Afraid not.
I did that after other efforts failed but still have to go through same issue every now and then. This is not a permanent problem but something that occurs at least once a day for me.

Also having Wifi issues with GN2 from Sprint
I got the GN2 on it's release date (this past Thursday) through Sprint. Got it home got set up, connected...everything worked beautifully.
After a couple of hours, downloading apps etc. I noticed it had stalled. Turned off WiFI and used the network to finish. Turned back on WiFi and Voila, action again, but a few hours later it stalled.
I first made sure all of my settings were in agreement. No sleep mode or anything like that was enabled. No power saver either.
Couple hours goes by, WiFi connectivity stalls (even though it shows a full signal) I contacted TWC and made sure it wasn't the modem/router. I changed the wifi channel, tinked with the bandwidth... everything worked...an hour later it stalled. Called Sprint they said I had a dud, took it back, exchanged it, got the new one... SAME ISSUES. YEsterday I connected to my Church network HOPING it was an issue at home, but not so. After an hour on the network it stalled.
Contacted Samsung today and they have had no complaints according to them so i said I'm happy to be the first... If anyone finds a fix please let me know.
PD

Do you have any solution yet? I have the same issues with 2 different networks. I already contacted Samsung, but they only say I should do a reset of my device and read the setup instuctions for wifi. I'm still in contact with Samsung and hardly try to get a solution.
Stay tuned, I'll post any news I can get.

I'd prefer it to work with the stronger encryption of WPA2 rather than WEP.

OP: it will be great if you could add a poll to the thread as that way we can see whats the percentage of users are experiencing this issue,
Thanks

I had this issue with my S3, but never with the Note 2. What i did in that instance was reinstall the OS and that seemed to have fixed the issue. Hope this helps!

Same issue here. Connect wifi and I'm able to hold connection for as little as minutes at times. Turn back on 4G and I'm fine. If I re enable wifi straight after it works intermittently. This is true of both my home and office wifi. So I'm lead to believe it's the phone.

Hi,
Almost the same thing here. everytime I go out of my home and comeback the wifi network seems to work but no internet access. I have to stop and restart wifi then it works.
very strange issue. ok I have a work around but I'm going to open a ticket to Samsung.

Same issue - connects for about 30 seconds
I've tried on different routers. Other devices (iphone, ipad, S3, etc.) all work fine. Sees the wifi network. connects, then disconnects and TURNS OFF WIFI. I can't figure out how to go to service mode to see if this is a timer issue. I've tried on both G and N networks. using a verizon fios, actionteck router (and netgear). Also, will not remember the password credentials. tried router reboot and fidling, etc. Driving me nuts. any suggestions ???

WiFi not auto connecting

My Note II is not automatically connecting to my home network. Instead, it just tells me there is a network available and I have to manually connect it through the notification. On my Infuse, after first connection there was an option to have it auto connect every time after that, but the Note II apparently does not have an option to turn it on and off. I'm guessing it's just supposed to do it automatically no matter what? I've hit forget and re-entered the password in hopes that would help, but I still the same problem.
This is on a stock phone, btw.

Maybe it's a problem with the router. Try resetting it also.

WiFi not auto-connecting (side-question: why would you NOT want to auto-connect?)
This is a huge problem for me as well, both at home and at work. It should be noted that my other devices (mostly iOS) don't have this issue so I'm not entirely convinced it's an issue at the router. If it IS an issue at the router what might it be? Maybe switching to a different channel would help? I'll certainly give it a shot.
I'm about to have a new router at home and will report back if that makes any difference.
(On a side note --> Strangely some of my searches have led to people asking about the opposite - I might be missing something but why would you WANT your WiFi NOT to connect or turn on? With a good connection available, shouldn't everyone want to connect? Saves battery and 4G data. I'm sincerely curious so if you know please do respond to this question as well. Maybe it has to do with privacy or battery life given an unstable connection or something.)

I got the same problem.
It started when I changed the wifi router (from Fritz!box to PKN Experia V8)
Now many times the device does not connect, but uses cell phone connection (meaning it uses the resources I pay for instead of my 'free' home wifi)
So, anyone who knows the solution, please tell me. I can only use Tasker to try to reconnect automatically, but it should not be needed!

[Q] Lost connection to Google all of a sudden.

And once again the problem has returned.
At first I wondered if it was a Google connection issue. Both connections would go grey. But I couldn't connect to anything. When I turn WiFi off, I'm able to connect to everything again with my mobile connection.
Running Cyanogenmod 10.1.2 on my AT&T GS3. Never had an issue like this before. Any ideas?

Really having trouble with this. Someone suggested WiFi fixer, it worked for all of 30 seconds and then WiFi stopped working again. I can't use my mobile connection for long because AT&T as we all know caps it like crazy.
Edit: Odd thing. An iPhone isn't connecting either. But the wireless computers in the house are. So maybe it's the router? It does appear to be the router. For now I think everyone can just ignore this.

I've posted similar questions with this phone, my old sprint Samsung epic 4g touch and my nexus 7, I did notice that it seems to be kernel dependant, some rom/kernel combinations cause the issue some don't.
Check to see if there is a firmware update for your router

[Q] Wifi issues

Hey guys,
So all of a sudden, my wifi is searching and not connecting in a campus setting. My Samsung Galaxy Note 10.1 2014 is still connected to the same wifi my Note 4 was. I have tried rebooting, removing battery, shutting off and on data and wifi, and airplane mode. Nothing reconnects it. Also tried forgetting all networks since there are 5 when searching for networks it finds and reconnecting to one, still no dice. It's been 4 hours, still can't reconnect. Any ideas?

Have you tried to forget the network and then ADD it with + Add Wi-Fi network? I actually had an issue playing with a Galaxy note 10.1 2012 edition, I turned my hotspot (sprint note 4) on and named it the same as our current network (was showing how open networks aren't always the network they say and anybody can create a Starbucks-Guest network.... I used starbucks-guest because I didn't want to put my schools on here). The tablet didn't see the network even after reboots, but when I added the network manually it connected right away. Also was this connecting to the same access points or different ones on the other side of campus?

Yep tried forgetting, re-adding the wifi spot and nothing.

I've been having wifi connection issues since day one of getting this phone.
Not sure if I have the same problem.
But at least once a day, it seems the phone can no longer make a connection to my wifi.
The only solution is to either just power off the phone and restart or do what Sprint asked me to do.
Sprint said to try and reset the network connection information by dialing ##72786#
The phone will power off and then restart do some background stuff and then power off again and restart.
Once that is done, all is fine.
I've never had this happen on any other of my Android devices. I even use a static IP with my phone setup.
And yes, I have tried just using the default of DHCP.
I had thought it was my router (Asus RT-AC68U) which transmits both 2.4ghz and 5ghz. I have both setup and I try to use 5ghz the most.
I did upgrade the router software because I was one version behind, but that did not fix anything.
Also, I had a Sprint femocell in my house (provided for free from Sprint) because I had bad signal issues years ago.. But because this phone uses LTE and now it seems the phone comes with built-in WiFi Calling. (Means instead of using the cellular network it will use my network and ISP to make Sprint calls, all voice and text messages come through normally, it's basically a built-in femocell).
I returned that, whoops still in the box, need to get that mailed out fast.
I'm not sure how widespread this issue is, but I suspect it's bigger that just the two of us here. And if I'm in the wrong thread, please let m know.
Thanks
