-Prior to my internet speed was great,like 1200-1400 Mbps Down and 200+ Mbps upload but after that it drastically dropped Not the Download it is the same or close to it but the upload now appears to max out around 64Mbps. Nothing has changed as far as my setup, my computer, my Ethernet cable. ( I run hardwired from my 2.5 Gbps Network card to the Xfinity 2.5 Gbps ethernet connection on the gateway.
As far as iRacing goes I am absolutely Steller there I have only had connection issues back when Xfinity woudl for some reason restart my gateway at like 03:15 sat morning about 45 min after my weekly NIS race would start, is early but have between 200-400 drivers racing at that time (In Different sessions of course)
After my 5th contact with Xfinity and basically explaining if this keeps happening I will have to end using their service and find something else. It was fixed right then never to happen again.
I noticed again when looking at the specs in the URL that something is not working correct in the gateway as my Ipv6 is not connected, my 4 Upstream channels only have 2 Showing as well as my 32 downstream channels are down a few as well and when I did a hard reboot then no upload channels were showing up and only 8 downstream ones.
To me that is obviously a issue with the Gateway or Xfinity Software.
