Since getting my lovely new iPhone 3G I’ve only been able to connect to my apartment’s Linksys WAG54G V.3 using 802.11b. It steadfastly refused to talk in “mixed” or “G-Only” mode when WPA-PSK encryption was turned on.
A little snooping behind the scenes, using the Organizer in Xcode to read the iPhone’s log, revealed that the poor little fella was having a problem with a “timeout waiting for authentication response” when connecting to the wireless LAN.
A little Googling and reading of anguished forum posts lead me to the solution. I just needed to upgrade the Firmware on the Linksys to v1.00.46.
Now my iPhone can enjoy the benefits of 802.11G. Success!
Perhaps this firmware upgrade will also fix my ADSL2+ signal strength issue too. Time to test…
