I tried upgrading once more to 12.04 after it went live. I had tried both Beta 1 and Beta 2. The problem is that now I'm getting sporadic network connectivity. My computer is hooked up straight to my modem/router combo -- it is hardwired, so wireless can be thrown out of the question. My other devices (Computers, Phone, Tablets, etc) all are able to connect correctly and this is only happening with 12.04. 11.10 works like a charm.

Output for ifconfig -a is as follows:

Again, this is sporadic. It sometimes doesn't do this on startup, and sometimes does. It will work fine for 10 mins or so, then not work for hours, then work for hours. I'm not a network guy by any means so most of what I just posted is foreign to me - anyone have any suggestions as to what to check and what the RX-ERR and TX-ERR are?

Thanks!
