Thank you for the reply. I think N network in the university is OK. Because, old computer connected it without any problem. The windows system can also connect it. From the output of wpa_supplicant, the authentication part works well. I've tried to use the latest drive from realtek. The firmware distribute is exactly the same as that in Ubuntu 11.04. But this will make core dump. I will try some other distributions. But the driver and the kernel are the same, so I don't think this will make any difference.
What kind of 802.11n network is your university running? What is the maximum data rate in Mbps? Are they using a 20 or 40 MHz bandwidth? Please have your network administrators give you that information so that I can try to duplicate the results. With my setup here, I have connected using the 2.4 GHz band with rates up to 130 Mbps. My setup uses WPA2-PSK, not EAP, but authentication does not seem to be your problem.
Every driver contains information about its authors. Use the 'modinfo rtl8192ce' command to get that information. Any reports of problems with a given driver should be sent to those listed authors with a Cc to the appropriate mailing list. I read the linux-wireless mailing list, thus I saw your posting, but my Chinese colleagues do not.
I received a new driver version from Realtek yesterday. I am still going through it to port the changes to the kernel driver. It is possible that your problem may have been found and fixed, but until you report what exact network conditions you have, I will not be able to confirm that.
