Problems with XDA app-somehow bad wifi

view story

http://forum.xda-developers.com – Hi, I've lived with this problem for a long time: Today I enabled wifi, connected, and XDA app took ages to load and said failed to connect to forum, but after turning on airplane mode then enable wifi it works perfectly! So, is it a problem in the kernel or radio? I'm using f3 aosp gingerbread with its kernel. Your reply is appreciated! :) Sent from my HTC Desire using xda app-developers app (HowTos)
