After upgrading to cat6 Ethernet cable and Gigabit Ethernet switch, I am

The 1 Gbps link speed sounds correct, so what does "craps out" mean? Have
you tried another Ethernet cable? Cat5, Cat5e, and Cat6 are all easily able
to link up at 1Gbps. Have you tried another switch, or another PC?

Does "still having problems" imply that you had a networking issue before
you upgraded?


Yes all problems with Ethernet were there with Cat 5e cable and a
100Mbps swith. The OS reports loss of connection to DNS.

So it's only a DNS issue, or is it more than that? Which DNS server(s) are
you using? Have you tried using other servers?

Do you have any networking issues if you bypass DNS, either by using IP
addresses directly or by putting entries in your hosts file?

What I'm getting at is that if this is only a DNS issue, then it suddenly
becomes relatively trivial to resolve.

BTW, here are a few DNS servers that you can try.
- 4.2.2.2 to 4.2.2.6
- 8.8.8.8 or 8.8.4.4
- either of the OpenDNS servers

Better yet, download and run DNSbench or Namebench to find a fast server
near you.
