I'm on Comcast, Mont County MD. XP with SP2. Problem is on my desktop
that is connected (coax) to the wireless modem that services my
laptop.
I get occasional and very short service interruptions - IE will
suddenly ask if I want to dial up (it seemingly does not remember that
I say "never dial up a connection") and other apps will lose their
internet connection briefly.
This seems to be related to the fact that I installed a new SB5100
modem recently. The log there will show that:
>Started Unicast Maintenance Ranging - No Response received - T3 time-out
Looks like Comcast fails to respond in time.
Whats up? Anyone else have this? Is there a timeout setting?

First of all, you might want to go into Network Properties and actually
disable your dialup connection. Don't remove it, just disable it. You can
always enable it again if you want to use it, but your browser or other
programs won't be able to use it automatically if your cable connection goes
down.

Second, I belive that area is about to upgraded to Bedrock. I saw a post to
that effect in the DSLReports Comcast forum to that effect. Before this
happens, lease times are dropped down to 1 hour, which usually means that
you get those disconnects every couple of hours until the work is done. So
check your lease times and see if you got a message in one of your Comcast
email accounts about it.

Jim, this may not be an issue, but are you running it on a USB port?
I've found sometimes that USB ports occasionally flake out and won't
hold a connection, whereas Ethernet ports are generally rock solid. If
you're running a USB connection, try it over Ethernet.

If that still doesn't work, it's possible they should re-provision
your modem from their end. It might not have been done right the first
time.

No, it's ethernet. Was always good with the old RCA rented modem.

Thanks, I'll consider that.
