Hardy Heron kept dropping network connection (both wired and wireless)
Hi, I'm using Hardy Heron on a old Thinkpad T41.
This is a fresh install system and I noticed it kept dropping wireless connection. After google around, seems like this is a common problem? Then I switched to wired network, and turned out the same thing happens again. Looks like doesn't matter wired or wireless, it kept dropping itself from time to time.
After checking syslog, I found something interesting...it kept complain eth0 is invalid, then it said it found a better connection???
I found that extremely weird... :(
