Uncorrectables on EVERY Channel / Slow Speed on Gig Connection

Hello,

 

I have a Gigabit connection and a Surfboard SB8200 modem. My router is a Netgear 7000P. I cannot get speeds above 380Mbps connected directly to the incoming ethernet line and it has been that way for months. When I first got the service 800+ was nornal. Numerous calls to customer service does nothing except them wanting to constantly reset my modem. I have attached the log that shows that every channel has uncorrectables. Any help with this would be greatly appreciated.

 

Thank You,

Steve

Hello,

I watched the video as advised and did everything that they advised. I waited a week and a half to see what the result would be and it is the same as before. All kinds of uncoorectables...

 

I have included the log as requested and the latest channel info.

 

Thank you for all of your help!

Are you still getting this ... I have similar issues resulting in Intermittant drops. But seem to be always the same time of day  9-11am   and 4-7pm  have same modem , and see the same large #of Uncorrectables.

 

Rebooting modem, factory reset, removing router from eqaution.. all have no effect .  Several calls to support but to no avail. no solution found. PLEASE HELP if you got this resolved .

 

Many thanks!!

 

PS .. also After Factory rest my modem event log  shows :
