So I’ve done a deep dive into an issue I’m having and discovered Xfinity line upgrades for their 10G network are causing major issues for customer owned modems.
What I found is the same story posted online many times by different people all having the same exact issues. Xfinity will notify you they are UPGRADING the line so your service will be down. Then when the service goes back up you will only have half of your advertised speed (half was 600mbps for me). The basic breakdown I found is they are sending the signal on new frequencies after line upgrades. If the modem you are using isn’t approved for those frequencies BY XFINITY then your speed will drop. Apparently they are not approving the modems to receive the signals.
I tried 3 Arris S33’s & a Netgear nighthawk 2050 and got the same results. Xfinity wouldn’t even allow me to install the last 2 Arris saying it’s not compatible for me anymore. Today I noticed they added 2 Gig availability to my home (oddly not any of my neighbors). So I upgraded with their equipment. After a quick install and putting their equipment into bridge mode I’m getting full speed on ipv4. IPv6 is clearly capped at 1200 on this tier. Upload is at 120.
Hopefully this saves someone the hours I put in as it was frustrating.
