Hello! I'm experiencing some slugging upload speeds (supposed to be 20Mbps), and I'm seeing some T3 timeout and Unicast Ranging received Abort Response in the modem logs. Would someone have a nosey at my connection from VMs end and see if there's anything engineer-worthy. There were some issues in my area last week, but they've been fixed according to VM.
(The stats below are from the past week)
Channel Frequency (Hz) Power (dBmV) SNR (dB) Modulation Channel ID
Channel Locked Status RxMER (dB) Pre RS Errors Post RS Errors
Channel Frequency (Hz) Power (dBmV) Symbol Rate (ksps) Modulation Channel ID
Channel Channel Type T1 Timeouts T2 Timeouts T3 Timeouts T4 Timeouts

Upstream power levels are high with quite a few T3 Timeouts. You also have loads of downstream post RS errors particularly on channels 2 and 3. All of this may well slow your upload speed.
Check all of your cables and connections are tight and secure and look at the server status page on the website. Also try a 30 second pinhole reset of the hub.
You may well still need an engineer.

Ps BQM minimum latency looks high to me too at around 21-22 ms.

I did the pinhole reset and reattached the cable to the modem and my upload speed is back to 20mbps. If everything's ok tomorrow I'll stick it back into modem mode and fire up my own router. 👍

Thanks for posting - apologies for the delayed reply and the upload speed issue. You were affected by an SNR (signal to noise ratio) issue - that's all fixed. Everything does look good following a system check, let me know if you need further assistance.

On Saturday the 11th there was an "intermittent signal" issue in my area and you can see the start of it – at around 11:50 – in the BQM graph below. The 5/6 spikes are manual reboots of my modem and router, as there was nothing on the status line, and the connection test on the status page said everything was hunky-dory in my area. Note the increase in maximum latency.
The status phone line eventually reported the intermittent signal issue, and then on Monday it changed to a "we're upgrading the network in your area" message. This work was carried out during Tuesday morning and ended around 08:30. Things looked almost back to normal between 08:30 and 10:30, and I rebooted my modem to reset the RS error count. The reboots throughout the day in the graph below are just me wondering if my VM hub and/or TP-Link AX1500 had gone wonky...
So, below is the current graph. The wall of increased max latency is still present, but speeds seem to be ok. The modem reboot at 01:00 wasn't a manual reboot.
Upstream power levels seem to be on the higher end of things 51/50.3/50.3/48.8, so could that be the cause of the increase in max latency? After making this post I'm going to switch my Hub 3 back to router mode to take the TP-Link out of the equation.

Thank you for coming back to us about your ongoing issues with your slow upload speeds.
After running some checks on your account, I cannot see any issues in your area that could be responsible for impacting your speeds or connection.
I have checked on your power levels as well and that all look good on our end. After you've put the Hub back to Router Mode, I would advise to do a Hub reset to see if this can even out any leftover issues.
Let us know how you get on and if you need any further assistance.
