I updated to ICS yesterday. My wifi seems to be in trouble 
My sola gets connected to my wifi router but it doesn't uses my internet. It shows connected to wifi but neither the gmail, gtalk, chrome, stock brower or the play store can connect to internet. However, using gprs everything works fine. If I restart the router or the wifi setting or the sola itself it works but only for 5-10 seconds and again stops.
Everything worked fine on .184 firmware. I have already repaired my handset twice but it doesn't solve the issue. So I reset the router and configured it again but no luck.
Any other ideas? Any help? I really liked ICS till now and don't want to switch back to GB :smileysad:. Sony support, you there?

I finally made it to work by changing the channel and the mode of my router. Below are the settings I used and I don't care what made it work (channel or the mode). I am not going to change them back.
There is still one weird thing, when I changed the region of my router to India it stopped working on my sola so I again changed it back to United States and it started to work again.
My Current router settings: working with the 6.1.1.B.1.10 firmware, ICS 4.0.4
| Channel: | 1 | |
| Mode: | 11bg mixed | |
| Channel Width: | 20MHz | |
| Max Tx Rate: | 54Mbps | |
My earlier router settings: working with the 6.0.B.3.184 firmware, GB 2.3.7
| Channel: | auto | |
| Mode: | 11bgn mixed | |
| Channel Width: | 20MHz | |
| Max Tx Rate: | 65Mbps | |
does it work with other routers?

The .184 firmware worked awesome but since I upgraded to ICS its not working. 
I already repaired twice with SUS and once with PCC still no luck. 
I have no way to try with another router today, hopefully I can test it with some other router tomorrow.
I am considering debrading/rooting as the last option.
Any other possible solution that might help?
it might be that youre not on the right channel
sola doesnt support channels above 11
to check
simple
1. what is a channel? read what annorax and adrian says
http://uk.answers.yahoo.com/question/index?qid=20100130145407AA5zj45
2. to check out what channel you are on
3. configure wifi channel
Note: I highly recommend you call your wifi network provider to provide you a step-by-step guide over the phone (hopefully toll free) to adjust your channel. Its easy to do and the second link will help you alot. But just in case. You might want to call them and ask them to guide you step-by-step.
I highly doubt that debranding it's going to fix this issue
LIke I said it worked on GB, the earlier .184 firmware I had. Shouldn't that mean that it will will work after rooting/debranding?
Also, I tried to test it with another router today, it had an unsecure connection so I was able to connect and use the internet. It seemed to work fine with that router but I am still not sure if it really worked coz the connection kept breaking at times so it might be the breaking that kept the internet going (as I said reconnecting the phone/restarting the router or the phone/ restarting the wifi setting makes it work for some time)
I will try to get a real good working router and test if its the ICS or my router.
I tried to configure my router and check its settings. The channel has been set to auto in that, what should be the right one? I am willing to do any kind of tests without losing ICS 
I also tried to change some other configuration but that only killed my router and I had to reset it.
