Hi,
This does not seem to be the same as the other wifi issues posted here - I did check before posting.
I have a problem that my Nexus 7 is not scanning for networks unless I press WPS button in the wifi settings. If I choose scan, switch wifi off and back on, or if it drops out for some other reason, it does not refresh the list of access points (i.e. it only shows saved networks, but does not attempt to connect to them). As soon as I press the WPS button, it starts scanning, once the access point I want appears, I can press cancel, and I can connect. This started after a couple of owning the device.
The problem isn't that it's dropping the connection (thankfully this doesn't happen too often, but it's annoying when it does, as it doesn't re-connect - I have to go back and press WPS again), it just fails to scan for networks until I hit WPS. My router at home doesn't support WPS, so this seems absurd. It's not just at home either, any access point, be it in a cafe, bar or office, it won't find any networks until I attempt to connect via WPS, then it shows all access points in range. The scan option from the settings appears to do nothing.
This started happening on 4.1, I was hoping the upgrade to 4.2 would fix it, but I'm still getting exactly the same symptoms after the upgrade.
Thanks,
Scott.
I am experiencing the same exact issue. I only see access points if I first press the WPS button and then cancel. Did you ever find a solution?

Yes, I did. I noticed that, even after a factory reset and rooting, my old wifi networks were still there. I deleted all the saved networks and the issue stopped occurring. It's re-appeared once since there after attempting to join a network at once my client's offices, deleting this particular network resolved the issue again.
Hope this works for you as well.

I've noticed that my [rooted] Vibrant frequently has trouble connecting, or staying connected, to WiFi networks.
At first I thought it was specific to my Verizon Actiontec WiFi router, however I've also noticed this at my office, where we use Motorola routers, as well as a few other locations that I frequent.
It's still possible that its a site-specific problem, but, less likely as I'm seeing this in a few locations.
Symptoms:
I configure my phone to connect to X network.
It successfully connects and all it fine.
I get out of range, it no longer sees network X and disconnects.
Some time later I return to my previous location and expect that in N seconds/minutes the phone will automatically reconnect.
A considerable amount of time passes and I notice it's still not connected.
I check the wifi settings and it days connection unsuccessful.
I tap the network, click connect and it works.
I've also noticed this after connecting to a network and the phone goes to 'sleep' or into an idle state. When a wake it up, it doesn't always automatically reconnect.
Anyone else seen this?
Any suggestions?
Many thanks.
i've had that problem. i am not sure what it was because I was rooted and Ryaned. I got sick of all the stupid lil bugs and had to wipe format and unroot. Now that I am back to the original condition, theres this sense of comfort knowing if something buggy happens, it's not "my" fault.
Thanks for the reply.
I noticed this prior to rooting and 'Ryan'ing'.
The capacitive buttons don't work all that well from time to time - specifically the Home button so maybe I should just exchange it. I'll call TMO tomorrow to see what they say.
This is a first time for this issue for me; my Wifi is scanning, but not connecting.
The settings look fine, I re-inputted the network passkey just to make sure, but it just doesn't connect...it just says scanning, though my home network is in the list.
My laptop can connect just fine as you can tell, I'm posting from it.
Can someone help?
Tried rebooting your modem/router?
I have this a lot of times waking up after sleep (I have the WiFi set to turn-off when the screen goes off)
Turn off then on the WiFi (wait a few seconds in between) resolves it.
(there are apps in the market where you can do this with a simple button press)
Well...I did reboot the router but had to go to work before I checked but it has to be the router...
I can connect just fine at work...
thanks for the suggestions...I'm glad it's working.
Hi, I recently bought a 16Gb DVP on WinMo7 and for three weeks had no Wifi problems at all. It recently stopped finding my home WiFi router.It finds both neigbours routers but mine is missing from the list.
I then got an update notification for the Mango update which I competed. the router didn't return in my list of networks immediately but about two days after.
It has now dissapeared again but 'Mango' has the added 'Advanced' button to see 'known neworks'. My home router is in this lst but I cant access the settings or force any paring.
I've tried the obvious of turning it off and on. I've reset my router, reset my phone back to a clean boot of windos 7.5 (mango) and still no results for finding my router. All the other phones in the house and all laptops find it fine so I can only presume it is the DVP.
Details:
OS version - 7.10.7720.68
Firmware Version - 2250.1800.7720.219
Don't know if this helps.
Does anyone hav any idea why and what I can do to resolve it.
thanks
Jock
Try changing the SSID (name of your wireless network) to something else and see if your DVP can see it and make sure the SSID is not hidden.
Thanks, tried that last night. No luck I'm afraid.
On the router admin now and It's all as it should be fom my service provider settings.
I have a full signal of my neighbours router and just don't understand why it's chosen mine to not even find. When it appeared last time it was after turning the router off all night. I tried that again last night but it didn't appear this morning when I turned it back on.
Confused !!!
Jock
have you been able to connect to and maintain future connections to other wireless networks? if the same problems happens with other networks, I'd run a factory restore on your phone as it seems there might be a software issue. However if you can connect and then are able to re-establish a Wifi connection to other networks then I'm stumped!
I've just changed the SSID to something completely different and it's appeared and I'm now connected again.
All I can say is that it connects to the router for around a week and then the network dissapears.
Short of changing the name every 7-10 days I can't really see another resolve.
In answer to your other question, I haven't really used it on other networks.
I'll see how it goes with this new name.
Thanks for all your help and suggestions
Jock
After reading other posts, this might be an issue with the .219 firmware that you are on. Just keep checking for updates. You could try a hard reset of the phone and then a reboot of the router
Also make sure your router is set to either B or G mode. Check my post here: http://forum.xda-developers.com/showthread.php?t=1324949
Thanks, I did a hard reset when it first went off, still found nothing when it re-booted. I'll keep an eye out for the firmware update.
Thanks again.
My phone just started doing this as well. Very frustrating as I cant download large updates and I dont want to exceed my data cap. I am totally fed up with this phone!
Fixed. Called Dell. Long press network name. Press delete. Press network name when it shows again. Reenter password. Works!
I have seen lots of issues concerning wifi but I haven't seen a thread with the same issues I have been experiencing.
When I turn on the phone I see all the local wifi networks and I can successfully connect to them. After a period of time (appears to be random) I lose connection. When I go to the wifi settings I don't see any of the local networks. In fact I can stand next to the router and it won't show up in the list of networks.
I have tried turning the wifi on/off but that doesn't have any affect. The only solution is to restart my phone i.e. rinse and repeat.
I have factory-reset my phone and didn't install from backup but that hasn't made any difference.
Has anyone seen this behaviour and do they have a solution?
Brother wish I knew why the wifi was such a mess but I can't get any answers either.
Same here, after endless search no wifi is found. Connection comes after restart only for minutes, but not always.

Have you experienced this when connected to other access points/routers?
Try turning off "turn on wifi automatically" (just suggestion)
select another channel on your router
Is the network you are having trouble with "hidden"?

Thanks for the responses. I was having issues accessing public wifis and my own private one (not hidden). I changed channel on the router with no success.
I reached out to Essential and they were very helpful and have subsequently replaced the phone.
Mine is a bit curious, sometimes after reboot it shows no sim-card and switches after seconds wifi off.
Could it be a faulty antenna or something? At the moment it works normal.
Hey,
I recently got a used Lenovo A7600-F tablet from my office because they weren't using it anyways.
Everything seems to work perfectly fine - except the wifi connection.
Code:
Model: Lenovo A7600-F
Android: 4.4.2 (no further update available for that model)
Kernel: 3.4.67
Build: A7600F_A442_000_029_150401_ROW
Here is the thing:
I disable/enable wifi
I click my home network and enter the password
Nothing happens for ~2 seconds
"Failed to connect to network" (no "connecting" or similar)
To make sure my WPA2 security isn't the problem, I made an unprotected hotspot on my phone. Absolutely identical problem.
One thing I noticed: The tablet is able to find all the networks around me and updates their signal strength in the list without any problems. As soon as I try to connect to one, it takes around 2 seconds until it says "Failed to connect to network". If I then try again, the message pops up instantly with no delay for all networks. From that moment on, the list also stops updating and can't be refreshed until I turn my wifi off and on again.
I downloaded "Wifi Analyzer" and I can see all the networks' strength values moving. I can close the app, do something else or go to standby and come back to see the values still updating. But as soon as I try to connect to a network, it will give that error again, stop updating the list in the wifi section and Wifi Analyzer will not be able to find any more signals. If I close that app and bring it back up now, the list of networks will remain empty. Same with the networklist on the wifi settings. Turning wifi off and on again resets the whole thing.
In short: My tablet sees all networks around me and updates them, but gives an error ("Failed to connect to network") as soon as I try to connect. Then no more wifi updates until i disable/enable it again.
Factory reset did not help, I let the battery drain and charged it back up - no success! I also tried an app called "Wifi Ruler", which was mentioned to fix a similar problem in a post I found on another forum. Connecting through that has exactly the same effect.
Does anybody have an idea about what is going wrong and what else I could try to fix this?
