Hello again -
I am (still, almost 6 months later) having trouble with intermittent drops from my modem, the Comcast ARRIS that I've been renting. I have exchanged the modem 4 times now, changed the coax cable, had 2 techs come out (both which replaced the wallplate and the wall cable) and spent numerous hours on the phone with tech support that do nothing but insist my modem is working fine.
The apparent problem seems to be the DHCP server being reset on and order of 10-15 times (on a good day) to over 100 times (on a bad day), rendering the internet more or less unusable. However, I would like to note, that yes, my internet does work fine whenever this problem is NOT happening.
I have a copy of my modem logs, as well as the SNR, US/DS, and if necessary, can post a tracert. While I cannot say with 100% certainty, this seems to happen daily from anywhere around 11am to 1pm, stablizing until around 8pm to 10pm, and then seems to drop whenever throughout the night. However, this does not happen every day, but, from the modem logs, these seem to be the relative times that this happens. I can also post multiple day router logs, but I have only included the ones from today.
