Packet loss and uncorrectable codewords after a maintence

Ever since 8/13 Maintenance for my local area the packet loss has returned to haunt me while gaming and streaming videos. The uncorrectable codewords have been going up on a few channels and i reset the router to maybe resolve the issue since there might have been a security flaw or connection issue to my devices

I use Ethernet connected to the gateway (XB8)

tested new cables and i have had this problem in the past but the technician that came out said my house is "end of line" which makes it so tuning the downstream power levels back into spec is not possible and i have had 3 techs come out to check all in house connections and no flaws just the downstream power is out of spec but it has been fine until 8/13 hopefully others are experiencing the same issue as me
