Modem not getting desired speed

Modem not getting desired speed

Hi

For a few months I ve been struggling with Comcast cause my Netgear C6900 modem is not getting even closer to 150 Mbps, which is the plan we are paying for. Today a tech guy came to check the wiring and ended up doing a whole new wiring. He then did some testing with my router and one of Comcast's and we were getting good speed. After half an hour, speed dropped down to usual again, between 30 and 50 Mpbs down. I was hoping the new wiring would solve the issue, but now, I dont know what else to do.

Can anybody explain what seems to be the problem ?

PS: I made sure this modem is Comcast compatible before buying it

If you haven't already, please post your equipment details (make/model of your modem/gateway/router) and a screenshot of your signal levels and your error/event log. Thank you!

Your signal levels aren't too bad, but your event log confirms your connection issues. 

 

I've asked an employee to check the headend server for real-time and historical signal reports from your modem. They can also check your local node/plant for any degradation or error reports. You can expect a reply in this thread.

FYI

The modem sometimes, very rarely, gauges speeds over 100 Mbps
