Hello, I have a problem with wi-fi on my iPhone 3G. While the phone normally joins my network (access point: Netgear WG602v3, firmware 1.2.5) and reports a good signal strength (3 bars), the connection is very slow. I have used tests like testmyiphone.com and the results are betweend 200 kb/s and 400 kb/s. Moreover, Youtube needs a very long time to buffer videos. My Macbook Pro is using the same access point without any of these problems. Now the interesting part: After setting the access point to 802.11b only, the iPhone works fine. As soon as I switch back to 802.11g only oder 802.11b/g combined the same problems occur. Things I have already tried: - Rebooting the iPhone - Rebooting the access point - Updating the iPhone to 2.0.1 - Updating the access point to the latest firmware (1.2.5) - Restoring the iPhone - Disabling wi-fi encryption - Various channels to avoid interference - Different RTS threshold and fragmentention length settings But nothing helped. In addition, I tested my iPhone at a local T-Mobile hotspot (I am from Germany). While I obviously couldn't change the access point settings, I did not get better results anyway.

Or is wi-fi working for you? Please let me know! Thanks for your help!
