Hello,
I experienced the same (trouble connecting to a WiFi Access Point), and some other strange behavior (unable to place telephone calls, several times) after updating my Nokia E-51 and restoring it's settings.
My work-around: Re-apply the firmware upgrade, but do not restore the phone settings by use of the Nokia PC Suite. Of course you can restore all other items, like contacts, messages, files, etc. automatically. However, apply all phone settings manually, including Access Point settings. Since I know my phone better now compared to the moment I just bought it, this only took me half an hour. Of course it is a bit of an annoyance, but I am glad that everything is working fine again!
I performed the upgrade because of some stability issues when using the phone in conjunction with the Parrot CK3100 car kit. I do not know whether these issues are resolved by this update.
What bothers me most (not to be solved by a firmware upgrade) is that after only just a couple of months of use a lot of fine dust has found its way between the LCD-screen and its glass cover. Do you guys experience the same problem? Please let me know!
