My Nexus 7 had no problem with wifi connections since I bought in right after they were first released. Last week, I bought a Virgin Broadband Mobile Hotspot to use while doing some traveling. (In some areas, it works a lot better than I expected.) The problem is that fairly frequently, the connection drops and I can't reconnect. When reselecting the device (or any other network) in the list of available wifi networks, I get an error message that reads "failed to connect to network." My only recourse is to reboot. A fast reboot is good enough, but I've done plenty of those and complete reboots.
Then, I can reconnect. That new connection may last ten minutes or many hours. But at some point, the connection will drop and I'll have to reboot to get another one.
I figured this must be related to the Virgin hardware, but when I got home yesterday, I discovered that this happened again with my router. In the 5 months I've had the Nexus 7, I've never had a problem connecting to my home router. So I "forgot" my remembered wifi networks and reestablished them. There are only two, my home router and the Virgin device. Didn't help. Right now, I don't have the Virgin device turned on, so maybe this will temporarily solve the problem. I'm not sure, yet.
One thing that seemed to help was that when driving and using the Google Navigation app, this seemed to be less of an issue. It's even possible that we never dropped a connection while navigation was active. When nav is active, the device doesn't sleep. So there may be some relation there. But plenty of connections were dropped while nav was off and the device was awake. In fact, most drops occur when I'm stationary, i.e., not in a moving car or walking around.
Another piece of info — our other Nexus 7, which also came along on the trip, doesn't seem to have this problem, but it didn't get used that much, so it may be that it would be there, we just didn't have the opportunity to see it happen.
Anyone seen anything like this and/or have any ideas about what to do about it? Why would I need to reboot to renew a connection?
I had a similar issue,it would see connections not connect automaticly and when trying to manually connect it would disappear.I shut off the autoscan for networks off and it works much better.
Hope this helps

Thanks. I'll play with that and see what happens.
The nexus 7 that I purchased for my wife last week is experiencing the similar issue. I can see many network in range but any connect I try to connect will return a message "failed to connect to network".
I found some submitted issues on the Android project thread, but none of them offered any solution.

I'll try this at some other places to make sure the problem persists and will probably return it.
Has anyone had any issues connecting to Wifi networks on their G2s? I got the verizon version on Saturday and haven't been able to get the phone working on 2 different wifi networks. I can connect to the wifi network just fine, but I can't access the internet at all. I can confirm that other devices are able to connect no problem.
Curious if anyone has some thoughts on how to potentially fix this. If not, will be heading back to Verizon to get a new one. Thanks in advance for the help.

I have the AT&T G2 version , it will connect to any wireless router but the connection will last 5 seconds then no internet, this is totally unacceptable I upgraded from the G-Pro and may go back as that never had this issue, I did read LG had a similar problem with the Nexus 4 and Optimus G
Mine works fine. I have a VZW G2 and an ATT G2 connected on the same router. It connects to both G and N networks.
No issues with my Verizon G2.

Did you try rebooting your router? I see this at home with the families iOS devices a lot, especially after heavy data traffic. I'll turn off the router for a couple hours or overnight and the next day all is well. Router is open, no encryption.

I have the exact same problem. It will sometimes transfer some data using browsers, but nothing on facebook, pandora, or the play store it will say connection lost or not data connection.
My wife has the same phone and it works no problem and also the laptop. Must be a dud wifi radio or something like that. Mine is going back to the store tomorrow.

Are you trying to use adblock by any chance? I was and it was causing the same issue you have. I uninstalled it and changed my proxy settings back to none and wifi is working great now.
Just received my LG G2 White brand new from T-Mobile about 2 hours ago. After many attempts to troubleshoot the issue it all failed. The problem is Wifi will connect to router and even work but after 30 seconds the connection goes down. The actual Wifi signal shows connected but no internet it gets stock. We tried resetting the phone and toggling with different features but still it did the same thing. T-Mobile is the worst they were trying to have me ship the phone back and leave me phone less for days. I complained and they are sending another one overnight but have charged me for the phone on my account. Mind you I've had months of bad service, after all I think I got a defective phone. I've read some other people having the same issue with other carriers. If I get another one with the same issue I'm jumping boat. If anyone knows of a work around let me know. I tried 2 different routers same issues connects then it randomly disconnects and stops downloading or transferring data.
Reset Phone - didn't work
Turned off mobile data - didn't work
Turned off wifi sleep - didn't work
I'm on Verizon. I have trouble with initial connection to wi-fi. It says obtaining IP address for a very long time. Even if I have a very strong signal. It takes about five minutes. It eventually connects and works fine. Then next time I try to connect to that router it works fine. It's only the first time I try to connect to a new router.
I just got this phone over the weekend and I was also having trouble connecting to my home wifi.
It would stay connected for 30 seconds or a couple of minutes then disconnect however the entire time the status under the Wi-Fi settings page says Connected even though I couldn't access the internet or the admin page of the router. Frustrating. If I turned off the mobile data, the wifi, the phone, the router, or some other unknown combination of events it would then reconnect again for another 30 seconds to a couple of minutes.
I called Verizon, they told me to take the phone back since I was within my 14 days. I did this and was optimistic. Then the new phone immediately experienced the same issue.
I did some more research, changed my router from 20 mhz channel width to auto 20/40 mhz. Not sure why it was set to just 20. I thought that would fix it. Nope.
I tried to set my phone to use a static IP, that didn't work either.
Then last night I tried the WPS Push Button option instead of using a password. This method worked and my phone stayed connected. I haven't had a chance to repeat my steps to verify it works again but wondering how other people are connecting, password, wps push button, wps pin? WPS is not my preferred option due to the security risks but just trying to track down what works and what doesn't.
I am able to connect at work just fine using a password.
I'm having a similar problem - my work network has no problem connecting while my home network almost never works with this phone (~25% of the time, other devices have no problem). Occasionally, resetting the phone or just turning on-and-off WiFi fixes the problem, but more often I just give up and use 4G. Anyway, if anyone finds a solution, please post! This is such a standard feature that should really work out of the box.
In case it helps, my home network uses "WPA/WPA2 PSK" security and my work connects to "802.1x EAP" security - also I'm not adverse to changing the security options if it fixes the problem.
Thanks! Nick
After reading more on this, I've decided this issue is router related not phone related.
I discovered my router reached end of life in April of this year is no longer receiving firmware updates. Newer versions of my router have received multiple updates since then.
I will be buying a new router. I report back on if it works.
I really don't think it is "router related" as all my other devices work as expected with my router. A new router may fix the problem, but I'm pretty sure the phone's WiFi is buggy and not the router..

In my situation it really appears to be how my router is handling the connection when I connect with a password since I can connect with limited security.
Does your router have a firmware update available for it? If so, have you applied it?
Received my new to me router yesterday with updated firmware as of 10/7/13.
My phone was connected for a few hours last night and I have not had any problems today. I'll report back if I start experiencing any issues but getting rid of my old, end of life router and replacing it with a newer router worked for me.
I did not buy a brand new router either. I went with a cradlepoint mbr95 which has been on the market for awhile and has already had a few firmware updates.
Check you wireless security settings
Had a similar issue to this and it seemingly was resolved when I moved the wireless router security over from WPA/WPA2 personal to WPA2 personal only. The phone found the WAP and connected right away. I tried to reproduce the behavior but alas I have not been able to do so. Perhaps this will help others.
hi guys
i found the problem
it happens just when you disable auto update in "settings>general>about phone>update center>software update>check automatically"
Hey all,
I've had my galaxy s5 since launch and just a couple days ago started to have a weird wifi issue. Whenever my phone wifi is turned on and connected, my home wifi significantly slows down. The moment I turn my phone wifi off, the home wifi speeds up again. This is not a router issue as the same problem occurs at my girlfriend's house and my friends house. Any ideas?
I have the very same issue and after talking to Apple Care because it seemed to be a router issue (Airport Extreme), I was told it was the antenna in the phone that was faulty. This never happened on my S4 or S3. I found an app that I made a shortcut to quickly turn the wifi off, then on, thus speeding things up. (WiFi Connection Fixer *ROOT* by ZEXTR.) I sure wish this issue would resolve itself on its own. Ever find anything?
This does not happen with my S5 and home router. So presumably it's some random conflict with your router settings.
It's impossible to more than speculate on a cause or solution though since you didn't provide any details. The best you can hope for is that someone has already experienced your situation, found a solution and reads this thread.
If you described your router configuration in depth, we'd have a lot more to go on. If possible, an ethereal session or router log at least would go a long way towards elucidating the situation.

Fix? Maybe! (Nope...Issue back)
I THINK I might have found the fix for this weird issue. Go to Settings > WiFi > "Smart network switch" and UNcheck it. My speeds have stayed consistently high for the last two hours, where normally after only 5 minutes, they would drop from 40-50 Mbps down to 10-13 Mbps. Here's hoping!
Sorry...didn't fix it.
Another Fix That is Sticking
I turned data OFF on my SGS5 by using a widget called "Data Enabler" and WiFi speeds have been flying (45-50 Mpbs.) for over 3 hours. (Previously, WiFi speeds dropped to 5-7 Mpbs after 10-15 minutes. Obviously, when I leave home or work where WiFi is not available, I will enable data again. Hope this helps others.
As the title says, when I leave the house and come back it doesn't automatically connect to WiFi, anyone else have this problem?
I've changed the 2.4 and 5ghz to manual with no joy, its back to auto now.
Any other ideas?
Same problem here... :/ Using a Nexus 6p as well, when I get home it never connects, need to turn wifi off, and then back on to be able to connect...
No problem here with my work and home WiFi, both 2.4Ghz and 5Ghz.
I had that problem and fixed it by changing channels and going down from 40mhz to 20mhz. Not sure which made the difference but my 6p connects right away now whilst before I had to toggle the WiFi.

I also have an issue connecting my Nexus 6P to my corporate Wifi network - I am seeking the specific details, but all I know so far is that it's a CISCO Access Point. The Nexus 6 had no problems at all. A colleague did briefly get his 6P connected, but then it appeared to break (he's not sure, but suspects it was after the November security update). It continually tried to connect and then eventually says Authentication problem (despite trying all sensible options for Forgetting, rebooting, changing password, confirming it still works for Nexus 6 w/ new password etc etc)
I am seeing this same issue with all of the 5GHz networks i use. It connects just fine but i need to choose it in the pulldown settings...does not automatically connect anymore.
This is something that started happening out of nowhere. it was fine after the latest update at the beginning of november but now has this issue.
Maybe reflash the system and clear the cache may do the trick but need to try.
Wondering why this is not an issue being spoken about more here. I'm sure its more widespread than it would seem here...
This is happening to my Nexus 6p too. when the phone switches to data network it doesnt connect back to wifi, i have to manually toggle the wifi on phone to connect to my wifi.
I have tried this at my friends home too and it doesnt look like an issue with the router, my nexus 6 connects compeletly fine without any issues.
Also I have noticed wifi disconnect when the screen is closed intermittently?
Is this an hardware issue?
Here is another person having the same problems. I changed my phone but I'm having the same issue on the new phone. It doesn't matter which location my phone is. It happens on every location.

Had the same thing. Connected just fine until something suddenly changed and it wasn't working anymore. It worked on other access points of the same WLAN as well as my home WLAN. Yesterday I changed the DNS Hostname of my Nexus (because "android-[insert random number here]" makes no sense) and suddenly it works again. Could be a coincidence though...
I've seen this issue on 5ghz networks on an HTC one m7, a Samsung galaxy s6 , this device and my Samsung Galaxy tab 4. It would seem to me it's an android issue.
Count me as another one with the automatic connectivity not working. Running stock 6.0.1 on Nexus 6P
I got my nexus 4 off my brother as he recently got a new phone. I replaced the battery with a new one and all seemed to be going well.
Everything is stock, I have even tried flashing a few older stock builds LMY48M/T to try fix this. I currently have my sim card in an old phone while I am having issues with this nexus 4. I cannot remember if these issues also effected my phone sim network too. I cannot test this until the weekend. I could have damaged the antenna when replacing the battery.. but then when the wifi does eventually connect, it stays connected fine.
I am unsure if it is a problem with my Nexus 4, or my BT HH 4 router.
The issue with the wifi is my home connection says 'Saved' but it never connects instantly. However I could put my phone down and come back some time later and it would have managed to connect. As soon as I turn wifi off, and then on again it will just say 'Saved' and not connect. Once connected wifi works perfectly, excellent signal strength and link speed.
Things I have tried so far:
- 2.4ghz only, 5ghz only, and automatic
- Factory resets multiple times
- Forgetting the wifi network and re-adding password
- Going into recovery and wipe cache partition
- Restarting router
-
As for my BT HH 4, every other device in the house has no issue connecting, (shield k1 tablet, HTC desire S, TF101 tablet, laptops, chromecast all fine) it is just the Nexus 4. Maybe someone could reply who is also with BT and has a Home Hub 4. I cant see how it would be an issue with my router since everything else can connect fine. For this reason I would rather avoid changing settings.
Here are some things showing up when trying to connect my nexus 4 to the wifi from the Home Hub logs.
- Client associated - Client disassociated over and over
- IN: BLOCK [9] Packet invalid in connection (tcp reset attack is suspected:
- BLOCKED 3 more packets (because of Packet invalid in connection)
I have spent so much time searching around trying to fix this and got nowhere, so hopefully someone can help. Any posts I did manage to find were from years ago, I tried the suggestions anyway and still no luck.
