Wireless Not Listing Access Points

Hi Guys,
Had my Desire a week now and loving it, but have a small by very frustrating problem. Sometimes and I have yet been able to reproduce this consistantly, the conneciton swaps to data from Wi-Fi while asleep, when I wake it up the phone works fine and uses the data connection but wont re-connect to the wireless.
In settings it list no avalable wireless networks, if I turn the wireless on and off it says its connecting to my network for a second and then gives up and says not in range, there are 5 other networks that should be in range and it list none of them. I have tried an app from the market that scans wireless and it has the same problem nothing is listed as seen. If I set airplane mode on and off the wireless jumps back into life lists all networks and connects back to mine. This has happened twice at home (uses WPA/PSK) and once at work (uses WEP).
As I said I cant reproduce this all the time and its fine to use the data connection but dont know why I have to airplane mode in order to get it back, do you guys think its a hardware or software problem am I rebooting the wireless hardware when I toggle airplane mode but not when I turn just wireless on/off? Should I try factory reset or send it back for repair? Has anyone else ever seen this?
Edit:- Sleep policy is Never.
Thanks for any advice.
Dan.
BTW- Stock T-Mobile ROM, not rooted.

Try a factory reset first and see how it goes from there

[SOLVED] WiFi not working properly? 3G/4G stays on due "My Account" App

So when i am home i have my WiFi on, which means my 4g is off. Now when the WiFi is on, i can not receive or send pictures. Also cant use the web or do anything like that but just send and receive text/calls.. and reason to this? maybe i have certain settings on that i don't know about? If i remember right, my wifi worked properly a few days ago.. but i cant remember exaclty. Help please? Thanks

no one knows?

Power cycle your router?

I've been having a different wifi issue. at home I have only edge coverage but I have petty good cable internet so obviously I want to use my wifi but for some reason the phone connects to wifi yet still uses the mobile network unless I turn off mobile data. My wifi sleep policy is set to never btw. Any ideas?

Also if I turn off mobile data while connected to wifi then turn it on while still connected it stays on wifi fine. Its like the mobile radio is preventing the wifi connection from fully initializing or something

Same issue!

I am having the same issue. I have to go into airplane mode, then turn on wifi to actually be able to use it... otherwise seems to default to mobile radio...

I have the same issue..this is what i do to work around it though:
1. Go to Settings>Wireless and Networks>Mobile Networks
2. Uncheck packet data, and then check it again.
Once i do this, my wifi works again, let me know if it works for you.

yes, does seem to work, but agree it's frustrating.... Hope they fix this soon.

Got this from the battery thread. This actually fixes the wifi issue on my SG2
The program is called Llama and can be downloaded from the market. I deleted all the default events and just added these 2. Hope this helps for all of you with this issue.

-- Add action: Toggle Mobile Data (off)
- Add another event called WiFi Disconnected
-- Add condition: WiFi Disconnected (any network)
-- Add action: WiFi Sleep Policy (sleeps when screen turns off)
-- Add action: Toggle Mobile Data (on)

Try freezing "my account". It toggles data even with WiFi is on. Try it and let me know.

Actually saw this tread and had Llama installed with these 2 profiles added and was till getting this issue... Going to try Freezing My Account to see if that helps... I know it helped with my wifi issues on my G2x.
Update: Nothing seems to work now. Can't have Wifi and cell radio on at the same time... can get calls but nothing else...

I've seen it occasionally as well. I haven't needed to reboot though. It usually recovers after I toggle WiFi on and off and mess with some other things.

I notice the same issue and I also toggle wifi on and off to get it to work back again.

Same here. I have to toggle wifi on/off and sometimes reconnect through wifi settings to get it back.

Recently I have noticed that the wifi on my phone stops working randomly...even though it says it's connected. Usually I can solve this problem by rebooting; should I return the device?

Yes, either return or warranty exchange for a new one, I have not noticed this issue with my device at all.

I've been having the same issue and it definitely causes excessive battery drain. Sometimes toggling wifi off then on works. Other times it requires toggling mobile data off then on.
I had it happen just now and tried freezing 'my account' in titanium backup as suggested and my 4g indicator immediately turned off. Sweet! It seems that 'my account' is the culprit!
Edit: I really wish this topic wasn't merged...I think there were a couple 'wifi problem' threads talking about different issues. To clarify, my problem was that while on wifi my 4G indicator would sometimes turn on and consume more battery and (sometimes) force all data to use 4G instead of wifi. Really annoying!

[Q] WiFi not working properly? 3G/4G stays on
My mobile data doesn't always turn off when wifi is on. Any ideas?

[Q] Ready to throw my GN against the wall. Wifi wont stay on!

Hi all, Im having a problem that is slowly driving me insane for the past 2 weeks. I surely cant be the only one. Anyway, I generally move between home and work daily, both have WIFI. When Im at home Im connected, all fine. I travel to work, WIFI isnt connected, again this is normal. I get into work and when I expect it be connected to WIFI it isnt, WIFI is off and I have to manually turn it back on to get it connected to WIFI again. Why do I have to do this? Why have all my other Android devices just worked normally and reconnect to known networks. Its soooo frustrating
Anyone have same problem or have a resolution?

What rom?What settings in phone wifi?

Both Stock rom, with and without the volume fix, and Modaco MCR4. Wifi settings are set as WIFI on even during sleep.
Is there some settings Im missing somewhere other than in Settings > Wireless & Netowrks > Wifi ??

Nope these are the settings.The strange thing for me is that your wifi turns off automatically

Try going to advanced WIFI settings and disable 'Avoid poor connections'

Yep. Try that. Only thing I can think of. My wifi was flaky with that setting on even 4 from my router. If that doesn't solve are you using any kind of task managing àpp?

I have posted this in other people's threads in regards to poor wifi reception. I recently purchased a 9250 through bell canada and have the same problem.
I have turned off the 'avoid poor connections' as well. It turns on and off on its own and can't get through a download of more then 5MB on wifi.
It will also reconnect on its own if I have left wifi turned on. I would say while WIFI is turned on I may actually be connected 30% of the time. This is 90% in 2 feet away from a router.

I'm having the same issue (wifi turning itself off) - noticed it the other day and just assume I'd caught the wi-fi button (I use extended controls). Happened again this morning and also just now as I got home.
I've not modded anything on my Nexus (4.0.1) - avoid poor connections has been disabled for a while.
I may test the theory, but betweek home and work is a wifi enabled bus journey, I never use it but it always tells me there's a wifi available. I might turn wifi notification off and see it if turns itself off before I get to work in the morning...

Left home with wifi on... Got to work and wifi was off? Wtf?
Could it be extended controls?

You are not the only one, it's happening to me in exactly the same scenario. Oddly enough it hasn't happened today.

i cant make out of your post thast the wifi on/off button turns of? or just the connection to the wifi adres?
i dont know about any sleep or auto turn of policy's as i didnt try it(i always turn off my wifi when travling)
but if its the last thing.
than the problem might not even be the GN.?
but the router it self.
even computer's and laptopt can have problems when the password is too long,or to different(hard characters like :';/.m,[email protected]#$%^&**(() ][ )
it might also be the MHZ setting,as the 20MHZ has wider range but can be disorted by machines like microwaves.
but the 40MHZ has lower range but wouldnt be disorted.
as there is also the channel option thats has been set wrong/or the pasword encryption. or any other router conflicting with the router you want to connect.
it might also be the router not liking your GN.(as my spica doesnt conect to my router at home,but all my other devices do.my router doesnt want to give a IP to my spica.)

It just happened to me again now, left the office whilst wifi was on and connected. Grabbed some lunch and returned (about 20 mins) and now my wifi button is set to off and I need to set it back to on.

Are there any policiys or settings for auto off?
you might also want to look into the power setting's,might be a power save feature.
And you are running stock? or??

Can't see any policy settings or any power save features. Running stock.

somehow I have fixed it. Problem is I don't know how.
Here is what I did in case anyone else needs help;
*From the 'My Vodafone' app, select wi-fi finder, in settings untick 'Enable BT Openzone'
*Settings, wi-fi, advanced, untick 'Network Notification', untick 'Avoid poor connections'
Not sure which of the above actually fixes it but my Wi-Fi has been on for about 1 1/2 days now.

Have you or when did you upgrade to 4.0.2? As the changelog mentions a wifi fixed. Only upgraded this morning so won't see if it has worked until I get home...

So I am still having this problem since day one. I have travelled through 3 countries and multiple cities and tried to use WIFI in at least 20+ different instances and the problem is the same.
It connects right away (really quickly actually) will stay connected for a bit then eventually loses connection.
I can't download any of the big packages for the games and so I can't play them. I won't use my data connection for anything over 100mb.
I got a message for an update yesterday. Updated the phone but I see no difference in the Android version number.
Anything happening with this?
I thought the update i was downloading was 4.0.2 but i guess it wasn't.
I am familar with updating and flashing from the galaxy s. But I want to use the phone completely stock for while.

I have just returned my nexus for a replacement. Lets see how it goes.
So far I have had the power shut off once while toggling the wifi widget (never happened on my other phone). And the wifi has disconnected twice. I have just done the update (not 4.0.2) and it seems to work a little better.

Called samsung yesterday after getting the replacement phone when it had the same issue (just as a reminder I have tried it on numerous routers/ap's) and they said they hadn't heard of the issue.
I said I was just calling to provide some feedback. They told me to return the phone yet again. I obviously believe I don't have a problem with the hardware at all. I figured if store let me return it, then why not.
Anyway onto my 3rd one today and the exact same problem.
I think that even though I am turning off "Avoid Poor Connections" it isn't actually turning that 'feature' off. Every so often and only if your watching the wifi settings it will say that it disconnected the wifi connection due to low signal.
Mind you all of this is 1' from my router while sitting at my computer. My galaxy S is sitting beside me and has maintained a wireless link to the router the entire time.

[Q] Wi-Fi Just Decided To Stop Working (Switches Off After 30 Seconds Or So) CM7

Hi All,
I am still lumbering on with an old HTC Desire running CM 7.07282011-Nightly and have had no real issues up until a couple of days ago.
Whilst in France (not that that make a lot of difference) the Wi-Fi access stopped working and the phone stopped being able to see any Wi-Fi networks. Basically, it switches itself off after around 30 seconds and cannot pick up any networks. In addiiton, the WiFi MAC address shows as unavailable although teathering via a WiFi hotspot works fine. I was switch between teather and normal Wi-Fi when the problem occurred.
If I go into Settings --> Wireless and Networks -->WiFi setting, then switch on the Wi-Fi, I get the "Turning on" message but then a Sorry warning saying "Application Settings (in process com.andriod.settings is not responding" and I can either "force a close" or "wait". If I wait, the Wi-Fi will simply switches itself off after about 30 seconds.
I did read in another post that this might be to do with the Wi-Fi sleep status but I tried all 3 options (from the menu in the Wi-Fi setting page) but that didn't do anything.
The issue appears to be that that phone has lost the Wi-Fi adaptors MAC address (says unavailable). However, I can still use Wireless Tethering and connect to to the phones WiFi hotspot. I think something has go screwy with the Wi-Fi tethering and Wi-Fi access (as I was switching between both when on my travels), but I need some help in trying to fix it.
Any Help Welcome
Chris

I tried updating to cm-7-20130301-NIGHTLY-bravo (whuch was the last release version), but still no joy.
Any help welcome

Well, after trying pretty much everything, I had to run a factory reset on the phone. Finally, my Wi-Fi is working again. Of course I now have the ball aching job of setting the phone up and re-installing all my apps again. Google restore is pretty rubbish
Looks like there must have been a config setting that got screwed somewhere. I did take a backup of the ROM and if anyone knows where this might be resolved, I wouldn't mind restoring.

5x lost data connection on Verizon

I have been using my 5x for a few weeks with no issues. I lost data connection today. I chatted with Verizon to see if it was on their end and they could not find anything. I have rebooted several times, removed and reinserted sim. I can make calls, just no data. Any suggestions before I do a factory reset??

I have issues with data all of the time. Usually it doesn't come back after a reboot if wifi is on. Toggling airplane mode brings it back.

I think it might be a bug where cellular data is turned off when Wifi is detected (which would explain why MMS on Verizon don't work if my Wifi is on). I've had the same problem and fixed it with the airplane trick too in the past but I've just noticed that in the Settings/Developer Options, there's a setting [Cellular data always active] which is "Off' by default. I'm wondering if this is the bug (Cellular data is turned off when the phone detects Wifi, probably to save battery, but is not turned back on when Wifi goes away...)
Anyway, I've set it to "On" and will test during the next few days and see if that helps!
