Arris SB8200 typically not getting above 265Mbps down

My average speed tests are running around 265Mbps down.  Occasionally I can get 365Mbps down.  When I talked with the tech he said to wait 24 hours and then call back.  If problems continued that Comcast would send someone out to troubleshoot.  I am in a newer housing community with a reputable builder (no really- and the house is less than 6 years old).

 

Any thoughts?

Is there a router / WiFi in the mix or with a direct connection to the modem ?

No Wifi. Hardline direct connect. Same issue regardless if I use my high end router or direct connect.

What do the modem's signal stats look like ? Try getting them here; http://192.168.100.1

Please post a screenshot of the *Downstream Power Level*, the *Upstream Power Level*, and the *SNR* (Signal to Noise Ratio) numbers.

27.8 Mbps - which I think is faster than what I had previously.

I'm going to try escalating your issue to the Comcast corporate employees that are available to the forums. You should expect a reply here in your topic. Good luck !

Hi, friedram - I can check if there are any issues with the signal levels/wiring that cause slow speed reports. Please send me a private message with your full name and the account holder's name as it's listed on the billing statement. Click on my name ComcastElla, then click Send a message.
