[Q] Fixing Wi-fi without reformatting?

Hey, in the last few weeks I've run into a very annoying bug on my phone. Wi-fi turns itself off after about 2 minutes. It doesn't actually "turn itself off" in the phone - and by that I mean that the wifi icon is still there, and I can see the signal strength, but the internet won't work.
In order to fix it, I have to turn the wifi off and then on again.
I've tried using the Wifi Fixer application, but it doesn't help. It can't seem to detect when I lose my internet connection.
I've also troubleshooted it, checking that it occurs on different routers/types of networks.
I'm sure it's a problem with my phone, but I dont really want to reformat my phone until Froyo comes (since I don't want to have to install all my apps twice).
Is there any solution to this? ;z
I'm on stock rom, JF3, with OCLF.
I have the same problem with my phone. My Wi-Fi at home works just fine, but when I go to my brother's house, I seem to occasionally lose internet connection even though it shows that it's still connected to the Wi-Fi. I have stock Bell ROM with OCLF by RyanZA. Oh, and to fix it I simply turn Wi-Fi off, and then on, and it starts working again.
Bump :x
Anyone have a solution?

Debugging phone connectivity

Hi guys,
I'm still working on figuring out the connectivity issues of my O2X. My problem has been that my data connectivity intermittently drops out, and fails to establish one and move out of WiFi range.
I have completely reset my phone to stock with the latest updates available in Norway. This is baseband 622, and version number 10c. The problem I am consistently having is that whenever I have stayed on one connection type (WiFi or 3G/edge) for any length of time and then switch, the phone fails to establish a connection through the other service. This means that whenever I have been home connected to my WiFi for awhile and move out, mobile data is not established. Similarly, when I get home, it does not automatically connect to my home WiFi network. In both cases the solution is to turn on and off WiFi mobile data (sometimes several times) to re-establish the connection.
If I quickly moved in and out a range of my WiFi, the switches between the two connections without any problems.
This is with everything stock. Is there any point in trying the other basebands? I have tried a few of them already, but without consistently good results.
The alternative solution is to send it in for repair, but they will only tested, figure out that they cannot locate the problem because they do not have the funds stay with the same connection long enough, flash the phone with the latest firmware, and send it back. After repeat this three times, I'm entitled to a refund or a new device, but it means that I will basically be without my phone for around six weeks.
Any and all solutions are greatly appreciated.
Edit: I guess a possible solution is just to use Tasker or something similar to reset mymobile data connection when I leave WiFi, and regularly reset WiFi when on mobile data.
I believe I have the same problem.
The 3G data connection would drop about every 10 minutes.
I got the phone a week ago and it too came with 10c firmware and 0622 baseband.
I believe that this is a hardware problem because I have flashed other firmware + baseband combos and yet this same problem still occurs.
I have sent the phone back for repairs yesterday. I hope that they can fix this problem.
Again, its probably baseband related....
Same for me here

[Q] Wifi dropped strangely

Hi all, I have been using ZR in 4.4.2 for half a month and everything was OK until today. My wifi connection is lost. The wifi network is shown in settings as excellent strength but when I try to connect, it just refuse and drop to a poor strength signal. That's not wifi router's problem because I am using the same wifi for my laptop and tablet. More weird is that I did try another wifi network, ZR connected and I could access Internet in some 30 seconds, then this wifi also dropped. I tried Wi-Fi Direct to send file to my laptop and it failed, too. I tried factory reset but the problem is still there. I have no idea, really. Do you guys have any suggestion? Thank you in advance.

Losing mobile data connection

Hi everyone, for some reason my Z3 compact keeps losing it's mobile data connection. Restarting the phone doesn't bring it back on and the only way I can find to get connection again is to change preferred network type from 4g to 3g then back again but as soon as I use a wifi connection again I get the same problem. I'm running the official Sony concept for M rom. thanks for any help you can give me.
in developer options there is a setting for "Cellular data always active", it might help, but the root cause is just that cell signal is too poor in your home area.
hope this helps.
