I think it is their dchp.

I think it is possible they have some switches that can only handle so many mac addresses - so they can only give out so many IPs.

It can cause really funky problems when the address tables get full.
That's just what ***I** think. It is very rare but it happens, I've seen it happen. Depends on the switches, the older ones are more limited.

I had the same problem last month - I was down nearly all last month. I called repeatedly, I got bullshit answers. Then, every night - they go down around 2 am alot - I'd lose my connection AGAIN.

I would suspect my equipment too - and believe me - they were NO HELP with even trying to help me troubleshoot - insisting I was just a stupid customer that needed to recycle my modem...

I changed out ALL my equipment and basic cables except my modem - it wasn't any of that. I changed it back and got a refund on the new router "Sorry, I didn't need this after all."

I knew it was not network cards here, then mysteriously I was back up and fine again - and my DAD was down. Then HE had trouble on and off for 3 weeks, I know, because everytime HE lost his connection - he'd freak when an Outlook box would pop up and mistype his password.

My DAD is ok now - but last Sunday I get a call from MY SISTER - she switched to AT&T (she can!) because she [i]couldn't keep Comcast connected[/i]

No, something is up. It might not be what **I**think it might be, but something's up.
... once when I called I got a fairly intelligent sounding guy - he told me there were 12 people showing as being out on my loop. HE admitted they were having problems - but that it was NOT being shown as an outtage- this was all after the DNS problems that caused a lot of outtages stuff were all supposedly solved. My dad and sister are not in the same city.
