HELP! Low Speeds on Gig1 HFC and high Post-RS Errors
Hello, I have GIG1 fibre HFC with the Hub 5 and I am not experiencing expected speeds both wired via Cat 6 and Wireless. Even on a Wi-Fi 6 Enabled device with a 1GB network adapter right next to the router I experience around 300MB - 350MB, and I occasionally do have dropouts on the network although none in the past day. This has got worse as compared to the 600MB I was previously receiving on the same device in the same location. I've taken a look at power levels and I believe these are fine based on Sephiroth's post (albeit this is outdated but I believe still true), however I am experiencing high Post-RS errors especially on Downstream channels 2 through 8 (where power levels are higher than the others), and channels 21 and 22. I am also seeing some MDD message timeouts. I was hoping someone could help me interpret the raw data to help me provide VM with a description of the issue so I can get this resolved via an Engineer if required sooner rather than later. Please see below information. Thanks in advance!
