View Full Version : [ubuntu] Can't connect to "N" network

Router: Netgear WNDR3300 with DD-WRT installed.
Radio 0 is set to N only 20Mhz channel width wpa2(aes) ssid (BeleriandN)
Radio 1 is set to mixed B and G wpa2(aes) ssid(Beleriand)

Clients: Lenovo X200 with intel 5300
Homebuilt with ralink based pci card

Problem: Neither machine can connect to the routers "N" only radio when running ubuntu. I have a windowsxp partition on the machine with the ralink card and it connects at 135Mbps. Both machines can connect to the b/g radio fine. When i switch network manager to the "BeleriandN" ssid this is what happens on the desktop machine...
/var/log/wpa_supplicant.log:

Is there some ubuntu "N" mode that I have to enable somewhere?
