SB6183 VPN drops, lots of uncorrectable errors

I have an ARRIS SB6183 modem and I have continued to have issues with my work VPN dropping.  Always at the worst times it seem.  I may have 10-20 reconnects a day.  This is not acceptable when you are working from home.

I have a wired ethernet connection.  I have tried 2 different routers;  One this I notice is that I have a high number of uncorrectable errors on the status page of the modem.

I power cycled my modem 5 days ago.  So the numbers you see here are for 5 days

    I'm just a customer but this most likely indicates noise ingress from the 900 MHz ISM band since your signal levels and SNRs are great but you have way too many errors in the 900-915 MHz range. If all of your interior cable connections are tight and all accessible cables have been replaced with brand new high quality RG6 cable, then you will need a Cox tech to fix the issue. Hopefully they will respond to you soon.
