I get ridiculously slow wi-Fi speeds with my iphone, slower than EDGE connection.
Settting 802.11b on router fixes the problem (http://forums.whirlpool.net.au/forum...4812#r16154812) but i have the Airport Extreme and there isnt any option to disable it.

Is there a way to disable 802.11g on iPhone (to have only 802.11b)
