Consistenly suffering lower than advertised speeds on the line, had numerous issues previously, but connection looks to be more stable now;
Issue persists across Ethernet (1Gb) and Wifi (Wifi6 with Wifi6 device/router etc).
I've tried removing the Asus RT-AX88U and using the Virgin Hub as a router and no improvement either, so it's not a modem mode/3rd party router issue.
Quick sanity check that I'm using a 1Gb cable for the WAN connection on the AX88u

Network Log - There's a pile of RCS errors that stopped on the 27th when I performed a factory reset of the modem at the behest of Virgin's 2nd line support, I was suffering consistent packet loss prior to this, which has been happening on and off for 12 months now, along with the slow speeds, I was hoping resolving the RCS errors would improve my speeds, but no luck.

Hi ToeJam85
Thank you for bringing this to our attention
Sorry you have had to though
I am more than happy to take a look at this for you
I will need to send you a private message to pass security
If you can check the purple envelope top right of your screen that would be great
Regards

Thanks Gareth, I've replied

Those details were perfect ToeJam85
I have ran a quick check on your Hub and ca see we have a slight issue with both the up and downstream channels
To get this fixed we need to send out a Technician
I have booked the first appointment we have available
You can check and reschedule this appointment through your online account if you need to
You can also cancel it if the fault has gone
Can you please let me know how the visit goes

Hello ToeJam85
Sorry for the late reply
Just wanted to see how things are after the visit?

Hey Gareth,
Thanks for booking the visit, engineer attended, swapped out the splitters and then booked the network team to come out and look at the streetside infrastructure, they replaced a waterlogged junction box and things seem better, I did have a brief outage this evening with some packet loss (5-10 seconds) but no errors in the log.
I'll keep an eye on it for a few days and update, looking better though!

Hi ToeJam85,
Thank you for the update. Glad your engineer visit went well and all looks good 😄
Please do keep us posted
