[2008.9] Wifi very unreliable

Im also inclined to think its a hardware/driver problem and have
nothing to do with wpa_supplicant or any other highlevel stuff. I
fully understand if higher stuff is left to the community but i did
expect the kernel and low level stuff to work a bit better than now
when i bought the phone. It could ofcourse be just some phones thats
broken and most works well because of some faulty batch.

Does anyone know if work is happening on the kernel side of wifi or is
it an orphan right now needing more people?
