Re: Network intermittently goes down constantly!

I'd look to the router and check its up/down times. Maybe it is retraining
frequently due to a bad config or a bad phone line.

Could be DNS issues I guess, but, "request timed out" really means that you
didn't receive a reply, not that your request was not sent. If you have
local/external DNS issues, you would probably have received a "could not
find host" type message.
