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.
