And it also seems to be on the same network, although a slightly
different connection. Please review your connections to make sure the
settings are all how they should be, and that your network is indeed
giving out the IP you really are expecting when the connection doesn't
work. Everything else related to the BIOS is probably coincidental, and
if not, it's a kernel issue.
