[It would require a different radio hardware. It's like saying what would it take to listen to FM radio stations from an AM radio = answer is: a new radio. - Dan]

We have been working with Apple on this, and they are working on a permanent resolution. So people who are having Wi-Fi problems may want to turn off their Bluetooth connection to see if that helps. Turning off Bluetooth definitely handles the issue when playing iSamurai over Wi-Fi (and turning off Wi-Fi handles the issue when playing over Bluetooth).

The problem keeps coming back on my iPhone 3G — at least once or twice a day. I’ve found that it is somehow cache related. I haven’t been able to keep any of my RSS reader apps installed (installing Byline in particular kills the wifi right away), and yet the problem still keeps coming back.

I’ve found that sometimes resetting the network settings, followed by a hard boot solves it, sometimes it’s as easy as clearing the browser cache and hard booting. Once I had to reset all settings to get it to come back. Definitely not happy.

From the behavior, I am thinking that Apple instituted some sort of hard limit on the caches directory or something and it’s not expiring / clearing correctly. Once it fills, the wifi driver can’t cache it’s network scans.

I’m going to reduce the size of my Mail’s IMAP folder to see if that resolves it. If mobilemail is also writing to that cache directory and if there is a hard limit on it’s size, that might explain why I am seeing it while so many others aren’t….

None of this helps:

Restting Network Settings (but it DID lose all my hotspot logins. great.)

Turning off BT (was never on)

Turning off Push

Standing 2 inches from the router

Using WiFi G only

Using a network with no other 2.4Gz devices within a mile!

Using many different brands and types of routers, Apple, non-Apple, and software base stations

Rebooting

Trying again and again and again

Half the time I can’t even see the network listed. When I can I can’t join. Ever. On ANY network. The device is near useless to me now. I could wait a month for 3.1…. or Apple could test better in the first place.
