This morning I've had intermittent broadband connectivity, which has made video calls impossible. I'm seeing an 'RCS Partial Service' error in the router log. I've tried rebooting the router, leaving it powered off for 10 minutes, but the error keeps coming back. I've also check the physical cable connections. Everything I've read in this forum indicates that it's a problem between the router and the outside world.
Here's my hub information:
Cable Modem StatusItem Status Comments
Acquired Downstream Channel (Hz)
Ranged Upstream Channel (Hz)
Downstream bonded channels
Channel Frequency (Hz) Power (dBmV) SNR (dB) Modulation Channel ID
The connections all seem good inside and outside the house. The router is in a networking cabinet so nothing should interfere with it. The service status says there are no issues in the area, and the equipment test came back all ok as well.
Which bit of the router log is telling you that there's interference?
By interference I think @Z92 means radio frequency noise. Your network log shows that your hub is losing upstream communication with VM's network gear (a "partial service" is where one or more channels have gone AWOL, can be up or down, but usually caused by the hub's upstream comms breaking down).
Then, if you look at your upstream data, all four channels are operating at 16QAM, when they should run at 64 QAM, which limits data throughput and indicates the hub is struggling to communicate, and your upstream power levels are all at the lower boundary of acceptable. So basically, the hub's whispering in a noisy pub. Over the other side of the bar, the VM network gear is saying back "I can't hear you", but all the hub is getting is "mmmfff...can't...mmmff...oooo".
This could be an area fault, or it could be specific to your line. As there's not much you can do beyond rebooting the hub I'll flag this for the forum staff to advise on some next steps, but that will take some hours as they're not a first line or real time response service. You could ring it in rather than wait, personally I'd rather have teeth pulled than deal with VM by phone.
