Modem losing internet connection throughout day
Several times per day I am losing internet connection briefly before the modem reconnects. ISP (wowway) says everything is ok on their end, so it must be either the modem or the actual physical conne...
Please post a copy and paste of the modems connection status page.
Have the ISP check the signal and line quality UP to the modem. Be sure the ISP provisions the modem correctly.
Be sure there are no coax cable line splitters in the between the modem and ISP service box.
Be sure your using good quality RG6 coax cable up to the modem.
Be sure to power OFF the modem for 1 minute them back ON.

Yes, Same issues starting around the same date June 10, 2021. Running perfect for a year before then. Xfinity firmware up to date V3.01.43 for Comcast. ISP contacted and completed proper provisioning - all ok on their end, yet continued dropped service and Cable Staus downstream bonded channels drops to much less (e.g.11) bonded pairs (seen status below in working condition). Downstream Channel was ~475000000. I did plenty of reboots. Interesting that my logs were showing DoS attacks only from June 10 - onward. Of course, Netgear community says all is normal with those.
FINALLY< I did a "factory reboot" from the Admin home of the Genie.
Current status from Cable Status menu is posted below and reflects all ok (for now).
Hope this fixes it? We'll see.
