so far so good for me since upgrading last night. I already had to stop myself from turning cell data off and wifi on from it becoming a habit from doing that the past 4 months!
will update once more after a week or so.

I never noticed this because I never use WiFi since AT&T is faster than my home internet, but I'm having a little bit different of an issue. We all know that WP sucks in a lot of aspects compared to Symbian, and dare I say Android.. Yes, I compare it to them because those are the OS's I own alongside it. Anyway, we all know about the WiFi issue where it goes in and out when the screen gets shut off. The app "Keep Alive" is one I've found to fix this.
The main issue I have however is that my 900 seems to just forget my WiFi connections that I've already setup in the phone. Example: I set up my home WiFi and it connects just fine and works perfectly. Then I shut it off for 3 weeks, and never try using it again. I come back to it, try to connect to WiFi and although it's saved in my WiFi connections list, it prompts me for the password again. I enter it correctly and it tells me that it's wrong. Every time. I have to go into my router settings, re-enter the password, save it, and then try on the 900 again, at which point it connects finally. It makes absolutely no sense at all, because I have to do this every time. My Razr Maxx, N8, E72, XT860 have zero issues with this, but the Lumia 900 does.

I've never turned on ICS (even though I have reset my phone), and I never use cellular data connection (it is turned off from begining), I only want to use internet using my home wifi but the problem is same. I automatically gets disconnected from wifi and cannot browse any sites (though wifi settings show "connected" with 100% wifi signal strength). turning wifi off and then on again corrects the problem but after 15 to 20 mins of continuous browsing it happens again. Please help.

I turn off my wi-fi at work, because of the firewall--so I WANT to use my data plan, but the wi-fi doesn't turn off, and my phone is still blocked by the firewall! (Even though the wi-fi indicator says the Wi-Fi is off, even after clearing cookies, and even after a soft reset).
