Title:
Network Adapter Realtek 8188ce doesn't work with PEAP mode under
802.11n
Status in “wpasupplicant” package in Ubuntu:
Confirmed
Bug description:
Binary package hint: wpasupplicant
MY university deployed 802.11n wireless LAN. However, my new T420
cannot connect to the network under ubuntu 11.04. I found the driver
for realtek 8188CE is rtl8192ce.ko, rtlwifi. I asked network
administrator to help me. They told me my wireless adapter didn't work
well with the 802.11n network. Is this because of the driver? The
following are the wpa_supplicant output. FYI
Ubuntu 2.6.38-8.42-generic 2.6.38.2
