The hardware network connection fails every few seconds or minutes. This really makes me frustrated!
The campus has just upgraded the network authentication by using 802.1X. We have to use an H3C client software to login the campus network, because they're using the Huawei-3Com routers. Every time I lose my network connection, I lose my login, and I have to logout explicitly after I fix the hardware connection problem and then try to re-login.
Before I get my network adapter fixed, I think I would not try to use any wireness connection, because the login procedure makes me feel that it's just a waste of time. If I want to use the Internet, I would like to find some place covered by wifi signal and use wireless connection, or maybe just use Opera mini in my phone and access the Internet via GPRS.
