Hi Amanda,
I've rebooted the router and the modem several times, and I've double checked that both the router and my network settings are set to auto detect DNS.
It appears I'm having the most problems with sites using https (secure) pages (i.e. This site, Facebook, Basecamp, Solve360, etc). On my hosting server, I'll be able to access the sites that aren't secure, but the secure sites will timeout.
It also seems better today...I had to refresh this community site only 4 times before it loaded.
Thanks,
Robin
