No WIFI after update to 4.3 on 3Gs

[ntrolf]

After Updating to 4.3. Wi-fi Networks cannnot be found anymore. On the Wifi menu the circle is turning for a second, done! no other comments from the phone. Before updating everything was fine!!

Resetting the Phone and the network settings didn't solve the problem!!
Recovering the Software didnt solver the problem either!

Help is needed!

Restore as new, and set up as a new phone.

I'm experiencing a similar issue only my 3GS is on 4.3.1. I'll try the advice above tomorrow and report back.

Restore as new, and set up as a new phone.

I tried that several times, no luck....

Good news!! WIFI Works

Bad news!! as soon as I move away from the antenna, I loose connection immediately after apr. 10 feet (Thats why I never had a WIFI connection within the last 2 weeks. since I Updated to 4.3. / 4.3.1)

Still not satisfying!

Any suggestions?

Kind Regards N.

Strangely, my phone seems to be working now after several restarts.

My phone is doing this too - it is very annoying. Any one know any fixes?

I had a perfectly working iPhone 4, was bored so I clicked yes to the 4.3.2 update and now the wifi I use in the office has gone as well as several others. The only ones that show up are strong 3 bar ones, e.g if I project a wifi off my MBP it can connect. All the wifi spots it use to detect just before the update is now gone! WTF?

I'm dealing with similar problems with my WIFI. It seems to be a jailbreak problem, here is why.
I had to restore the phone to 4.3.3 and wifi would work with no problems at all, the phone will detect absolutely everything in the air. Once I jailbroke the phone, it will not detect anything.
any ideas?
