Request Remote Adjustment: G36 Signal Levels Out of Spec
I’m using an Arris G36 on Xfinity and my download speeds are lower than expected. My modem’s current signal levels are here:

According to Arris, the recommended ranges for the G36 are here:

I am in full bridge mode, so my router is not affecting these levels. It looks like my downstream/upstream QAM levels are out of spec, which is likely causing the speed issues.
I already have a tech visit scheduled for Oct 30, but I would prefer this to be handled remotely if possible. Please confirm if a remote adjustment can be done and cancel the scheduled appointment if so.
Thank you for checking this and confirming next steps.

They can't be adjusted remotely. They are ok. And whether in bridge mode or not can not affect the RF / DOCSIS WAN side of the device. Something else is going on. Is there a separate router in the mix here ? Are you testing via WiFi or hard-wired Ethernet ? What speeds are you subscribed to ? What speeds are you getting ?

Hi there and welcome to Comcast @Bosswinner. Thank you so much for reaching out to us regarding your internet speeds concerns. Have you tried to test your connecting connecting directly to the modem via Ethernet and bypassing the router?
