This morning I plugged it into the ethernet, which goes through the hub to the router to the cable modem, and always just "works." Then I turned on the power and waited for it to boot, First thing I did was to run the link command to copy the DNS addresses from /etc/resolv.conf to the copy in chroot, because otherwise I wouldn't able to go anywhere with Firefox. Then I launched Sylpheed to check e-mail, using the "Get All" button on the toolbar (I have three accounts set up in Sylpheed). It happily went to two of the servers, but said that the connection failed on one of them. Note that Sylpheed is running in 64-bit world, so it should not need the link command to go anywhere. Puzzled, I swiveled my chair around and tried it with Pegasus on the Windows desktop. No problem getting to that account.

Using the Windows computer I pinged some of the places that the laptop couldn't find, then pinged the IP address from the laptop, and the laptop could find the server. So it's a DNS issue. And throughout, the Windows desktop could go anywhere. I don't get this. Somehow the laptop is not getting the DNS server entries from the network, but I know little about how these things work. It just seems to me that it should work 100% or not at all. It's acting like my house wiring when one side of the incoming lines is down -- half the circuits work and the other half are dead.

And I seriously need this computer for at least another day and a half until finals are over, 'cause it's got everything on it. It's all backed up, but I don't have time to rebuild things until Friday. Someone please tell me the problem is simple!
