Ever since my downstream channel was moved from docsys 3.0 to 3.1 my speeds refuse to go over 250mbps down. I have the 300/30 package and would average over 400bps down. Using the arris docsys 3.1 modem
If so, I would factory reset the R6250. It sounds like it might be hacked and gave away your public IP address.
I think OP sees unusual activity of IPs trying to remotly connect to their computer when the modem is in place. I have been following(silently) their Reddit posts and I think some have pushed OP into thinking it could be a signal problem. Is there anyway to check that D3.1(OFDM) system in the area are working? Any tickets assigned to the node?
Yes I have a Mac mini hardwired. It still tops out at 250. Very odd
Heres a before and after 3.1 upgrade. Seems to be capped at 250. I was super excited for docsys3.1 too
