Having weird issue with mobile hotspot:
1. Turn it On and it turns on fine
2. Connect using computer - connected fine
3. Can use it for around 30 seconds, then computer goes to limited access
4. Try turning it off - gives error
Any idea?
I thought it may be because I put custom kernel/Rom, etc but now I have reverted back to Indian KF3 Rom using Odin, still same issue.
I have tried it with both the wap.cingular APN and with the mmsc.cingular APN and still same.
I get that problem when I newly connect an android device to my laptop. Maybe you didn't define where the network is in Win7. It usually asks if it's home, work or public. Until you set that it usually shows limited access.

I get the exact same behaviour as you. I'm using the factory KF3 ROM, never rooted or installed custom ROMs.
Did you find a solution?
As someone else said have you both selected what sort of connection it is? (Home, Work, Public)
Has your phone got full, or near full charge? Has your phone got a good, solid internet connection?

Fresh flash of WM 6.5 over radio 3.42.50 on a Titan. Under Network Management, I've selected that "Programs that automatically connect to the internet should connect using:" My Work Network, since I don't have a data plan. I go to Wifi settings, select Add New, put in the ssid, click through the security settings (temporarily disabled for this test purpose). My network shows up as "Unavailable". (I'm standing right next to the router). I click "Connect", it says "Connecting" for a couple of seconds and then goes back to "Unavailable".
What should I check first? I'm at my wits end.
You shouldn't have to "add new", your ssid should be automatically discovered and displayed in the list of wifi networks.
Did you connect to a wifi with your phone before, or is it a first attempt ?
Yes, I'd been connecting just fine until a few weeks ago. In fact, the refusal to connect was what prompted me to flash the thing -- figured that starting over might help.
So, your wifi connection was working well, but suddenly, for some obscure reason, it stopped working. Therefore, you decided to reflash your phone, but it didn't help, still not working.
Is that correct ?
I know I sound like a complete doofus, but yes, that's basically it. The weirdest thing is that every once in a while it'll find a wireless network and connect. But the connection never lasts for more than a few minutes, and then when it's gone the network is "Unavailable". And to anticipate your next question: There doesn't seem to be any rhyme or reason for when it works. At this point I'm thinking I'll pick up a used Titan or Vogue on eBay and junk this thing.
Did you try a different rom ? Could be a faulty rom.
I've tried several different roms, yes.
this happens in some roms...
go2 wireless lan settings and then go2 power mode.change it to best perfomance frm best battery
Hi, I am trying to connect to my wifi, and my phone can see it. I even tried reinstalling my rom. However I still cannot use my wifi, even though my phone can see it. First it says it is available then when I press connect it goes to "connecting..." then it says unavailable and gets back to 1st stage. I was thinking maybe reinstall the radio? or it is in my modem?*
* I used it few days ago so doubt it the modem, because nothing changed...
I would still check the modem/router settings. I had the same problem and after a few days I realized I had MAC filter on. Or maybe check the encryption method if it's the same in both devices.

Well something changed!
If you have tried all the known routes (all settings checked and working?) and still no connection then a reset to default and then apply all necessary settings again should do the trick.
Bought my Galaxy yesterday and it works fine but on one point. Yesterday I was able to find the home network of my friend in his house. I could connect to the internet with that as well as through 3g. But later at my place it does not work with any home network. When I try Settings, Wireless and network, Wi-Fi settings and Wi-Fi, the phone turns on Wi-Fi and scans for some seconds and the leaves a message that says "Unable to scan networks".
Maybe I have switched on or off something accidentally as I am a new user on this phone? Anyone for help?
turn off the phone
then turn it back on
in another words, reboot your phone, seems like it got stuck in some WiFi bug
It does not seem to help. I even took out the battery. Still unable to to scan
you can try this
*2767*3855# WARNING! FACTORY DATA WIPE AND RESET as soon as you enter the last # use it only if you want to clean wipe your phone

I really don't want that as long as I also cannot backup the video in it. Have not got the Kies program to recognize the phone yet.
Maybe there is another way to set the scan possibility?

you don't need kies
see the last secret code?
It defaults to User space. I do not yet have any extra Micro SD card. Is it that what means with User space?
Tried that last command and do have at least one file of each in the folders, but the phone answers for each of them that the files are not ready? What else is there to be done?
Had same problem, tried factory reset... didn't solve it. any ideas? it can't get an ip address and it used to work
probably the next best thing is to use Odin to reflash the modem file to the phone
or a full flash to the latest firmware
Same problem appeared on my SGS. Boy this sucks. The wifi became "hard" to connect sometimes. Or I could connect but had no internet access. Then I disconnect and connect several times to have net access.
One hour ago the wifi died. I turn it on it says "Unable to search for networks" and shuts itself off.
WTF. I have to reflash!!!! Not good. Also I don't know what caused this. I'm on JM2 with One Click Lag fix 2.1
one thing is for sure, the STOCK rom has no problem with that
so it is either a Router thing, or a firmware specific problem

JM2 isn't a final release firmware. Realistically, if you want everything (well, other than GPS) to "just work", stick to official firmware.
Well, I for one, have only the the official firmware and it is the latest one what I have learned. Still the phone behaves as in my original post after just a couple of hours. Is this and other peoples beautiful Samsung Galaxy model not tested enough by Samsung? Has anyone more information than we have?

I agree thats Help me. or you can try upload update.zip (file to make root) on your device and flash that can help too.
Hi all! Thank you for your inputs to my problem. I have now got it working. For those who are interested how, I can tell you that I only did a simple Factory Reset command.
problem solved!
I had the same problem.
I was trying to configure a invisible ssid and by distraction I created a normal WPA 2 network, ending up with two networks with the same ssid (when I was turning off the wifi, it wouldn't go off at the first try, weird, )
Solution:
Edit the "/data/wifi/bcm_supp.conf" (with root permission) and eliminate the duplicated network, problem solved! At least in my case (no need for factory reset )

Creating a new topic, because the other one is tagged as solved, but it doesnt solve my problem however.
So my wifi is not working, it's connecting to any wifi hotspot but not sending data thru that, which ends in failing loading any pages on IE, cannot download any apps from market and so on...
Anyway this is what I tried so far:
1. Flashed to stock rogers (also tried different Tango roms)
2. Did hard reset procedure via hardware keys (Format all Yes)
3. Did hard reset procedure via About menu
4. Did hard reset procedure via Samsung Diagnosis code sequence
5. Logged to my wifi network, everything looks fine at this point.
6. Opened IE and entered google.com:
"We're having trouble connecting to this webpage" (sometimes no error message but white page with scrolling bars appearing on touch)
7. Tried to access my wifi router via IP address (192.168.1.1) - the same results like above
8. Tried to ping my Samsung Fous IP (192.168.1.18) from my PC with success
9. Disabled wifi network security on home wifi router, the Focus still not working
Additionaly tried a method that fix issues with wifi after using latest wp7 tools, but it didnt help at all.
When using my providers APN there is no problem with opening pages on IE etc., but it's not Wifi.... Internet is also working if I have USB cable plugged in, but again it's not wifi.
Cannot use warranty, the phone is from the USA and I'm in Europe... without any warranty service.
What else I can do, maybe there are some diagnosis codes that can actually help with real diagnosis on what happened with wifi on my phone?
Hello again (from the other thread). For completeness, add the following:
- current OS version
- did/not use WindowBreak
- when did the problem start (if you can identify an event and OS version/revision) - or you noticed
There might be a test for wireless in the "diagnosis codes"... Good luck!
After you use the diagnosis fix, it might take some time, mine didn't work immediately but after some time, it detected my home network. But it seems you are able to connect but internet does not work, this is certainly issue with router/DNS settings in your phone, because I have faced these problems in iPhone, it might wrongly mapped to unreachable ip, but never faced this issue in Windows Phone, you might try changing the default gateway/dns settings, you should also reset your modem/router, and try basic setup before WPA/WPA2 setup

Hi there
Currently using 7.10.8773.98, (MAGLDR 2.0) but tried different versions, even vanilla pre-mango ones, they didnt work well with wifi on my phone either. I checked it at friends home wifi, which is totaly different network and routers.
I never used WindowBreak, never had to because my phone was already unlocked long time ago with ChevronWP7 application.
Noticed the problem about 2 weeks ago, but I didnt use wifi too much, so it could started much earlier. Last installed application was WP7 Tools 0.8 alpha, and all I did back then was using some built-in tweaks (3G?) if there is any, cant remember to be honest but for sure I wasnt editing registry or anything like that, I just play some games from time to time, cant event tell why I installed it, maybe because I noticed there is a new version. I cant tell because I never paid attention to it especially with rare wifi usage at a time.
I have isolated the problem I guess, and it's not the phone's fault. Something wrong with the main access point (Mikrotik) at my place. This is weird because everything is working just not on Samsung Focus. I digged thru many options and couldnt find anything that blocked or stuff like that. Well took it to totaly different place and another wifi network, and guess what - it's connecting to wifi with data flow...
Anyway consider this topic as solved.
I tried searching and I have not found a solution yet. I'm running SHOstock-I with ktoonz kernel on android 4.4.2.
For some reason, my Wifi randomly disconnects from any currently connected wifi network. The first thing I try to do is to connect back to the wifi network (any available network), but it simply tries and says "Connection Failed". Next, I try to disable the wifi connectivity alltogether, but after I tap the toggle button it becomes "greyed-out" and I can't toggle it.. it just hangs. If I go back a step and then select wifi again, then I can try to disable it but the same thing just happens again.
If I reboot, then wifi works again.
Oddly enough, if I enable/disable teathering, then wifi starts to work again.
It seems I can't run Wifi for more than an hour without this issue happening. It seems to have just started doing this out of the blue. I suspect a full wipe would solve the issue but I'd rather not do that unless I have to. It usually takes me a while to get things back to normal after a wipe.
Any ideas?
Some solved the problem by unInstalling the Smart Wifi utility (for ATT and maybe other carriers too).

Thanks, but I don't have that app installed. I am positive this is not a router issue as well.
Everytime I wipe cache/delvik then the issue doesn't occur for a few days, which I think is odd. I also tried different kernels and the problem persisted.
Does anyone know if it's possible to confirm if this is a hardware issue? I doubt it...

It is a good idea to turn off any 'connection optimizer' or 'wifi optimizer' application or setting, in short anything that decides what connection is selected based on available connections should be turned off. The most probable reason for the problem is badly programmed software.
