Subject: Re: working usb wifi card, that is still possible to buy
Hi!
So... these are my results of wifi testing. 802.11n driver currently
working on powerpc is rtl8712 -- staging -- EMTEC Wi350 ...
802.11 A+N card available is DLINK DWA-160, but carl9170 driver did
disconnect during tests of less than one hour...
