Wifi Troubleshooting - Galaxy Tab 7.7 General

My device was working perfectly fine today until suddenly it stopped being able to find any Wifi networks of any kind. It doesn't say there's any issue, it still scans, but it doesn't find anything at all. I'm searching on my uni campus, so I know that in any one place there's about 12 connections, and my phone has no issue finding them.
I've done a factory restore, but it didn't seem to help in any way. Is there anything anyone can suggest?
Edit:
Bluetooth still works, but I'm not sure if they're on the same chip in the 7.7

I just had similar issue with my home wifi,
Other devices works fine, and there's no problem connecting to other wifis..
I tried deleting the dhcp list via root explorer, tried wifi fix, rebooting couple of times but none worked..
Then i tried to reboot the router and surprisingly it works!
It's probably because the router is giving a static address that's different with the previously recorded in your tab.. But i'm not sure..
So if your tab still works in other wifis then chances are the router needs to be restarted..

No WiFi networks show up at -all-. I've got a completely blank list, even though there's plenty of connections available.

How I solved Wifi problem

Lately I have been reading many post related to Wifi problems in the HD. I had the same. Even I was very near my router I couldn't connect to the net and the signal was very weak.
So I entered my router configuration and I found a solution.
Before, for security options I had: WPA-PSK [TKIP] then I changed to WPA2-PSK [AES] (of course you also have to change your HD connection configuratoin), and now it works great¡¡¡¡
Now I have all the bars for the signal and I can connect very easily.
Hope it works for other people
I have a similar WiFi connectivity problem, but after reading of the poor service provided by most vendors and HTC itself, I will try to gather some more experience with the problem before I contact HTC or my vendor, and hopefully find a solution. Bellow is my experience so far:
I own an HTC Touch HD since January and have a similar problem, only it surfaced last week. Before I had only used the WiFi connectivity briefly. The problems started after I installed an AP on my house expressively for the new PDA. The node is fully open and set to B/G/N protocols.
After a couple days of medium (couple hours per day) use the WiFi connection suddenly quit, the device would try to connect (the top bar showing the WiFi connection animation continuously) and after a few moments gave up with a dialog box stating the current network settings were wrong (even thou they worked fine a few hours earlier).
I tried several hot and cold resets, but only solved the problem after flashing a new ROM; even then the same symptoms reappeared after a couple of days of regular use. Again no re-setting would cure the problem, and now not even flashing the ROM again would work. Nonetheless, some hours latter the WiFi would connect perfectly with the same nodes it refused to before, and in very short time.
I have witnessed this cycle twice and have yet not been able to find a trigger for it, but will keep my eyes open for any tell tale signs, and post any findings here.
I could add to the above mentioned problems.
i got a new hd just few days back.
The wifi worked great. But now it doesnt.
I have disabled wifi, so can start it whenever i require.
I click on wifi button to enable it.
Then open opera, try any website.
it will open fine.
For instance say my email at gmail.com
Now after that if i try to open anysites or even continue with my mail, it shows error saying connection not available.
One of the workaround is to go back to toggele wifi off and switched it on.
Not sure if anyone faces a similar issue.
I's been about a week since my last post and I have already witnessed a couple of cycles of WiFi connecting perfectly and then not connecting at all.
No matter the settings I try after it decides not to connect, it won't. Even to nodes it had connected perfectly and fast jus minutes before.
I thought re-flashing might help but so far has proven ineffective. Once I thought some part of the non-volitile memory was causing the problem since after I cleared the memory I could connect for a while.
Any thoughts anyone?
Same problems here.
For the last hour I have been reading 10ths of threads here concerning WiFi problems.
My HD's WiFi worked fine on my home and outside for about 2 months. Now it doesn't. It reports connection, but no program can use the internet. At best, it seems to be able to exchange some Kbytes the for just a few seconds after a connection is established. Then nothing. Connected but unusable.
Tried everything Internet/My Work/My ISP, WAP enabled/disabled, soft/hard reset, everything.
When connected through ActiveSync everything works fine, all programs see internet.
Has anybody taken their HD to the service? Has any HTC service worldwide identified the problem as hardware and solved it by replacing something?

I have just encountered a similar problem, but already used wpa/wpa2 with aes. Have tried a hard reset with no joy. My old HTC Touch has no probs connecting via wifi nor does my laptop so I would surmise that the prob is with the HD and not the router.
I am going to try flashing with the latest version of Duttys 6.1 rom and see what gives.
Edit: Tried flashing with new rom with no success. Take a look at this post.
http://forum.xda-developers.com/showpost.php?p=3769339&postcount=7
There are a couple of files to download but i only used the second ie this one.
http://forum.xda-developers.com/showpost.php?p=1363759&postcount=2
Now no problems and can connect via wifi no probs, ip address assigned by dhcp.
Try to go into WiFi settings and move the power slider to max performance. I need to do it here to access my router. This happened also with my HTC TyTN II, with any recent radio firmware. The original WM 6.0 ROM and it's radio work fine in low power mode, but the new ones appear connected but are always at 1 Mbps and there's no traffic until you move the slider to performance mode.
You go into WiFi settings and you configure manual IP and DNS so as router.
DNS is important.
Whit manual configuration, Wifi work always.
(sorry for my english)

This is not a solution. I didn 't buy the device to be able to connect to my home WiFi only. What about public hotspots? Or hotels? Or whatever outside your home?

Skyfire will connect to internet, NOTHING else on my phone will??

This is very odd. Suddenly today I'm getting connection errors (GPRS) on every program on my phone EXCEPT for Skyfire. Skyfire can connect and surf the net with no problem, but not one other app on my phone will connect to the net, and I've tried several browsers as well as apps that connect directly (i.e. YouTube, Google Maps, etc).
I'm on AT&T in the US (New Orleans, specifically). I've checked and triple-checked my Media Net connection settings, and nothing has changed that I can see since the last time I was able to use it successfully. I've soft-reset several times, to no avail. I don't know if this is an issue, but while I was using WiFiWMRouter yesterday, it crashed. But I used the "Reset All Settings" function of that which is a crash cleanup of sorts, and still no luck.
What else can I check? It would seem that if it were an AT&T issue, Skyfire wouldn't be able to connect either!
Weird, I have the exact same problem too. I probably wouldn't have known that Skyfire could connect until I saw your post. My problem began (I think) when I uninstalled WMWifiRouter last night. I haven't gotten a connection with any other app since then. I had a hell of a time uninstalling an old version or WMWR I had installed just so I could install the PAID version and now it is apparently causing problems even on uninstall...
To add to this - I've confirmed that devices connected with ICS can connect to the internet through the phone. So it seems to me that the problem is related to some wifi settings (maybe that WMWR sets up) that aren't being "released" when wifi is turned off/disconnected.
If I do a hard reset the connection seems fine. If I then restore a backup from right before the problem started the connection is okay, but only until I try wifi again. From then on it's borked until I restore the backup again... frustrating as hell.
FWIW - I think I pinned down what was going on with my phone. In my wifi settings something (probably WMWR or Phojo) had set a static IP when establishing an ad-hoc network and didn't revert to "obtain an IP address automatically" when I quit/uninstalled the program. I don't know why the IP address of the wifi network adapter affects my cellular data connection, but setting that to "obtain automatically" and turning wifi back off allowed my phone to connect again. So it seems like it was using that IP address regardless.

Can't connect to WiFi using Touch HD

Hi everyone.
First off, I know there are a million and one other threads.. believe me.. I have searched!
Basically my phone won't connect to my network. It was working fine earlier today. I've tried changing all the security settings in my router (turning off encryption for example). I've tried soft resetting and hard resetting the phone.
Nothing seems to be working. It finds the network fine, but it just says 'Connecting' then goes to 'Available' but it won't use the wifi connection.
Any ideas?
Thanks!
Have you tried connecting your device using a friends wifi router to see if this connect you
Nope. I forgot to add that I will try connecting to work's WiFi tomorrow!
Anything to try in the mean time?
Try these:
1) disable frame bursting
2) disable big packets and other methods of wifi speeding
3) force 11b
4) use WPA-PSK TKIP only
5) check if you have MAC or other access filtering
than let us know

1) Can't see any settings under my router.
2) Tried disabling gnitro (Belkin router), no difference.
3) No difference
4) Already on that.
5) Turned off.
It's so odd. Works fine with an N95.
I don't think it's anything to do with my router because like I said it worked fine earlier on in the day then suddenly stopped. The router settings hadn't changed.
Edit: I've tried turning the router security off altogether also. I really don't feel it's an issue with my router.
Tested the phone at work. It works fine.. so I don't have a clue why it's not working at home? Surely the router can't be incompatible with the phone.. especially considering it worked at one point.
Very weird! I got fed up with my router so decided to restore the factory defaults and start from scratch.. worked straight away! So I restored the settings back to exactly how they were before (using a backup file I made).. and it worked!
Just posting incase it happens to anyone else anyway.

Maybe uve tried this already but could be the fact that your home internet access point is listed as Work rather than internet, used to have an issue with mine cause of that.
I also have this problem.
Reset did not help.
Listed as internet or work did not help in both cases.
Real weird!!
I've got the same problem, all of a sudden my hd won't connect to my router.
I can connect to open networks (wi-fi hotspots etc) so i know the wifi in the phone is working ok and my partners diamond can connect ok to my router, so the router is obviously ok.
Have reset the router as well and haven't changed any settings on the phone.
Don't understand!!!!
as other users point out within other threads, it seems that Blackstone has a problem connecting to wifi networks when WPA Authentification is enabled
try to disable it. it worked for me and soem other guys
good luck!
I could connect to my router fine using my laptop.. but I still had to reset my router to the factory settings before it worked again on my Touch HD.. then I could enable WPA and everything back again. So try that!
i thought i had a similiar problem, mine wouldnt connect to wifi, kept switching itself off. figured this is normal when its connected to usb. unplug usb and it turns back on!

Hi
I used to have problem using any secure wireless connection. Then I realized that you need a personal certificate to use secure wireless networks. It uses certificate to encrypt connection between access point. I have access to a windows certificate server so I created a personal certificate with private key and import it to my mobile. Now I can login to any secure wireless network.

This may help, may not. Let me know

That solution doesn't seem to work for this problem.
Resetting the router does seem to work.
I don't get why resetting the router works.... other devices can still connect no problems before resetting, so it only seems to be aproblem with the hd.
It also sux when you are using a public router with this problem that you can't reset.
Connecting to Belkin router
Guys, I had the same problem as well. HTC touch HD used to connect to the router fine but after installing an update/upgrade it would pick the signal from the router but would not connect. (I was using WEP authentication at this time)
SOLUTION:
Go to belkin router configuration on the web.
Under security change the Securtiy Mode to WPA/WPA2-Personal(PSK)
Change authentication to WPA-PSK
Select Encryption to TKIP and enter your password.
GO to your HTC touch HD's WiFi setting and turn Wifi ON. Select your home network SSID and edit it using the information you used on the router i.e. WPA-PSK ; TKIP, enter your key/password and click next, next and finish.
Worked for me....hope it helps.
WIFI not connecting
That truly is extremly nasty.
I have the same issue - wifi found, correct password (WEP, WPA all settings) but no successful connection.
Took an old HTC 3xxx - runs immediately.
I can not reset the router - there are too many users, they will kill me then.
So I installed an Access point (Sparklan WX 7800A) to play with.
Notebooks (HP, MSI and ASUS) have successful internet access, also the old HTC 3xxx.
But still the HTC HD does not connect.
Tried "WIFI Monster" - shows the wifi, but does not connect.
(But it deletes all wifi entries easily - so you can set them up new)
Tried with NO security/password: same issue.
WEP, WPA (all kinds): no connection
There must be something to be changed in the registry - but I have no idea what & where.
Or is the wifi that useless ?????
Maybe someone can help
Ciao
Mike
I had the same problem. But the problem stopped when i connect my htc HD to my laptop and used activesync to connect to internet. After i disconnected it, open wifi and... works ok!!

WIFI issues

Hi Everyone,
I have a strange issue,
My wifi works, but today it won't recognize my work wifi even though it was connected to it on Friday.
I've tried everything I can think of to solve this issue, but the problem is only at work.
I just tried a free spot down the street and it connected to it no problem but it refuses to even acknowledge the fact that I have wifi at work...my laptop and and iphone are both connected, just the Nexus...
I've read os "similar" things happening to other people, but I would love to solve and know more about this if anyone has any info.
Thanks,
Lou
EDIT
I played around some more, and solved the problem.
I went to settings - wireless and networs - wifi settings - then the menu button, and went to advanced settings.
From here I went to regulatory domain and forced 14 channels and it seems to work now.
Hope this helps someone
L
Seems like they removed that option in the patch.
Cant find it anymore and my WiFi is not really working as it should any longer.. I get a connection speed of only 5mbps sitting very close to my AP. :-/
since update, my wifi is very fidgity. loses my house wifi all the time now. seems like every time the phone goes to sleep. my router is the schizz, so it shouldn't be because of lack of signal.

Wifi on Lolipop 5.0 G870A will not connect

For the last week or two I have been unable to connect my phone to wifi networks.
At first the problem would be that I was getting disconnected from any wifi network I joined, now I can't connect at all.
The wifi networks page sometimes (not always) does not detect a strong network even if I am standing a few feet away and the phone has previously connected and other APs are connected and working like my pc
If I try to connect then I get the "Connecting" status followed by "Saved,secured"
I have searched the internet looking for a fix to this and tried wiping the cache partition, forgetting the network, airplane mode toggling on and off, apps that wipe the known network list and some others including lastly a factory reset on the phone but nothing seems to remedy the issue.
From the wifi router I have tried using an unencrypted (open) connection
Now I think I may also be having problems with the bluetooth connecting in the car but I haven't had a chance to really investigate that one yet and it may or may not be related to the last factory reset.
My phone is not rooted.
Build no. LRX21T.G870AUCU2B0F3
kernel3.4.0-4443965

Can anyone offer any assistance to my current issue ?

I have just confirmed that the Bluetooth in my car is not detecting my phone when it scans (the phone bt is switch on and the visible box being checked) so that's both radios with similar issues.

Im having same issue with wifi... sm-g900r4
I just stumbled on a clue, while using an app called 'wifi cleaner' there is a feature allowing you connect to wifi networks within the app. I type in the password, authenticating is shown on the screen followed by "incorrect password".
I know the password to be correct..
Mmm

I was wondering if you ever got this issue fixed?
I thought I had but the problem comes back in a different way.
Sometimes wifi connects but only connects at 5 mbps.
Now wifi will not turn on at all. ( radio button is greyed in settings)
I did find a thread on xda where some Motorola users were having the wifi off issue and it was due to a missing system file which could be replaced on a rooted device. However I don't have root on my s5 g870a and it's not likely I can get it.
