I have the same behavior with Videotron here in canada. a power off for 2-3 minutes does the trick everytime. On Sat, May 10, 2014 at 10:58 PM, Aaron C. de Bruyn wrote: > Good to know. > > Slightly OT, but why would they have ARP cache timeouts of four hours? > What benefit do you get with suc

Good to know. Slightly OT, but why would they have ARP cache timeouts of four hours? What benefit do you get with such high cache times as opposed to the obvious support calls you will get when equipment is swapped around? -A On Sat, May 10, 2014 at 7:55 PM, Moshe Katz wrote: > On Fri, May 9

You may want to make sure the DHCP server is disabled on the modem completely. I’ve noticed that caused issues in the past for me. The default user/pass is cusadmin/highspeed on those modems. On May 10, 2014, at 2:19, Aaron C. de Bruyn wrote: > Yeah--I figured it was related to the MAC address

I’m not running CARP but I am doing many things like yours on my Comcast Business account… I’ve never had that happen - and I think my modem only reboots when I lose power (it’s on the UPS but not on battery - by design). Which modem did they install? I suspect it’s a firmware “feature” of that
