I have a Buffalo WLI-UC-G301N Wireless USB dongle which works just fine when I boot my machine to Windows. However, using it with Linux (Mandirva One 2011.0, kernel 2.6.39.4-5.1-generic) via the rt2800usb driver, the connection speed starts out at about 1/10th of what I get under Windows, then after a while there's extremely high packet loss (as shown by
ping 10.0.0.1) and it just stops working altogether except in short bursts. As suggested
in this thread I tried turning off power management (
iwconfig wlan power off) and tried giving the
rt2800usb driver the
nohwcrypt parameter, but neither helped.
My
/etc/sysconfig/network-scripts/wlan1 file:
