Ive seen about 4-6 posts with seemingly similar issues. I also have the issue where you can not access the modem gui management page.i’ve been at the same location for 7yrs, had optimum residential cable, business cable, and now switched back to residential service for better price and 1gig service.

Sb8200 only getting 100mbps on a 1gbps plan

had a zfinity technician rule out the splitter, coax cable, and ethernet cable a possible cause, down to being the modem itself causing the problem. what could be the reason for this failure. also i am hard wired to it (no router in between). could it be a hardware failure on the inside of the pcb board? if so which component that i may de sauder and re sauder.

SB8200 wont stay connected with Xfinity provider

My provider uses Xfinity and they say that the modem has issues on their end they say it is connecting and then drops it over and over...the modem is pretty much brand new...I refuse to believe it is unable to push the small town providers 1 gig speeds I know it's not the WiFi router cuz Ethernet from modem straight to my laptop is still not connecting...anyone know what my issue may be? And yes it's been provisioned to the provider this issue just started tonight

sb8200 wont connect to router

My modem will not provide internet access to either of the two Wi-Fi routers I have tried. The lan cable works with my ps5 so I know internet is coming to the modem. I have netgear routers. I have reset all of them and turned off and turned on all of them. Any other ideas?
