imageUsers Reporting Wi-Fi Connectivity Issues after Upgrading to iPhone OS 3.0

Based on this long Apple Discussion thread, it looks like many iPhone users are facing Wi-Fi connectivity issues after upgrading to iPhone OS 3.0. They are reporting that after upgrading to iPhone OS 3.0, their iPhone either cannot maintain a Wi-Fi connection or it doesn't download data once it is...

    iPhone 3GS OS 3.0 - I've noticed that my reception of wifi is much much weaker and on relatively rare occasions i can stand still near my router and the signal can fluctuate from one bar to full signal randomly, but as for the complete lack in connectivity and/or network activity and reduced speeds, I'm not experiencing that.

    I've read somewhere else, when I first read about this issue, that putting the phone in the freezer for a bit can improve wifi experiences. I'm not speaking from first hand knowledge however. I'm hesitant to try this out for myself.

    Yeah I read about it as a solution in the discussion thread but it sounded
    stranger than the problem at hand :)

    Maybe you can try it if the above solutions don't work.

    Did any of these potential fixes work:

    - Turn Wi-Fi off then on in Settings.
    - “Forget” the currently configured connection and allow it to
    reconfigure.
    - Switch the router to WPA2.
    - Remove all spaces from the WPA pass phrase.
    - Remove all security from the router until a stable connection is
    attained then reconfigure the security.

    My experience suggest that the 3.x OS has a real issue with "N" wide band Wi-Fi. I have a linksys WRT350N router and an ipod touch 2g. Before the upgrade to 3.0 on the ipod touch it had no issue connecting to my WRT350N in wide mode "N" after the upgrade it can not maintain a connection if the WRT350N is in wide "N" mode.

    I must now put the WRT350N into slower non wide mode, in order for my ipod touch 2g to connect, or for my 3Gs to connect! Also there seem to be an issue with the power save mode of operation, in that I must now reboot the wireless router every few days for the ipod touch or 3Gs to connect to the router and be able to download, data.

    I've 3x3G & 1x3Gs in the family, all on OS 3.0 (not 3.0.1), all jailbroken, one of the 3G's had wifi problem and I've sent it back to Movistar (live in Spain), will see if they fix it.

    Also have an old 2G where wifi been lost "forever", only way to get it to work is the freezer trick, i.e it seems to overheat somehow. Anyway its in the box of old mobile's nowadays.

    I had the same issue but solved it.

    Just reset your Network Settings(Settings-General-Reset). Now my phone works perfectly.

    I noticed this not too long ago as well. I can not keep a connection at all.

    So here is a quick fix.

    All I do is go into Settings, Select Airplane Mode and turn it on. Exit settings, then go back in and turn Airplane mode off...

    So far this has worked for me 100% and I get a connection right away. Although, its not a permanent fix, I will have to do this every time I lose connection.

    I have tried the other suggestions listed above and they did not work for me.

    Seems (for me and a lot of others on various discussion areas) this only happens when I have bluetooth turned on.

    My connection drops low or altogether when I have BT enabled and I access an app that uses the network.

    Disabling bluetooth immediately returns my wifi connection to 100%.

    With my phone, this is so obvious, I am in a routine where I enable BT if I need to use my headset and instinctively disable bluetooth after my call.

    I try to use mine at the YMCA and their system blocks it because when I open safari it automatically tries to go to apple.com/downloaditunes in the background. Ymca blocks it and kicks me off.
    any fixes?
