[Q] Post ICS upgrade - won't connect to secured Wifi

[JDMpire]

This is a problems I'm having now with my GS2 and ICS(current is Bezke rom and Pure rom prior to that). Both of these ICS roms exhibit the same problem, it will see the wifi spot (its a Apple time machine and the connection uses WPA protection), it just won't connect to it.... EVER. The router is also just in the next room, so it has a perfect strong signal.

I did not have a problem before the ICS upgrade, it connected to the wifi spot just fine. As far as I'm concerned this is NOT a hardware problem but in software. I have had this issue with MANY MANY other high end android phones (I go through a lot), so much so that I got a 2nd router and run it open just for my android phones. I've tried utilities that "reset" the phone settings to help connect (not sure what that means, maybe like a DNS flush or ipconfig release/renew kind of deal...) but they never work.

Ive searched online for this issue and apparently thousands of others have had this same issue, but I don't remember seeing any talk of what exactly the problem is, or what to fix it (aside from flashing another rom). I would rather not be flashing every rom under the sun until I finally get it working, but I might just have to.

I really like this phone (I also have a 4S but don't use it because I like this Samsung so much) and plan on keeping this a while. Its a GT-I9100 BTW and not a carrier branded device, I have it on T-Mobile US.

I'm probably going to try the official Sammy rom next and see what happens. FWIW my last phone that had this problem was a Optimus 3D and it was running STOCK F/W and still would not connect. C'MON GOOGLE! WTF, This is a problem, can we PLEASE get it fixed

Can i take it that you have tried connecting with no security setup on the WiFi router first .

Same problem here. Just upgraded two S2's at work. Went thru the process to 2.3.4 and 2.3.5 and once in 4.0.3 neither of them worked using our cisco wifi. Remember having the same problem on the old HTC Hero, but the Desire and the Sensation (both 2.3.5 and 4.0.3) works fine, as do iPhones and some tablets.

Problem must lie within the S2 since we have loads of computers and other phones connected. Have tried static settings instead of dhcp but the setup on the phone is quite limited.

Same here

9.5-9.7 Resurrection ICS based on XXLPH/XXLPJ won't connect to wpa2 secured University wifi. I've tried the official XXLPQ by Samsung and everything works like a charm.

It installed the XXLPQ so that is a no go. Tried connecting to a htc sensation hotspot and that worked. They just don't want to connect to the Cisco.

Encryption requres screen lock

I'm on campus Wi-Fi a lot. apparently "credential storage" used on these enterprise networks can only be used when you have a screen lock pin code set up

Does that help?

trying to find a way around it myself, I dont want to have to type a pin in every time I pick up my phone when I'm sitting in my apartment streaming pandora.

Sorry I forgot to reply back, but I ended up "cheating" and getting another router SPECIFICALLY for my android devices that dont like wifi security. I got a coupon in the mail for a free wifi router (N too!), its pretty low end but hey, it works.

Sure thats not really fixing the issue with the phone, but Ive gotten to the point of so much frustration, if I try any further to fix the phone and fail I'll either end up destroying the thing, turning to drugs or both.

Sadly, that last sentence was not hyperbole, Im serious. HOWEVER the phone is working, so all is well here
