Can you check whether the PostRS and T errors are building up with time - they shouldn't.

Your down power levels are all at the top of the range (+10 to -6 dBmV) which may not help - a VM person needs to look at the connection

I do not work for VM. My services: HD TV on VIP (+ Sky Sports & Movies & BT sport), x3 V6 boxes (1 wired, 2 on WiFi) Hub5 in modem mode with Apple Airport Extreme Router +2 Airport Express's & TP-Link Archer C64 WAP. On Volt 350Mbps, Talk Anytime Phone, x2 Mobile SIM only iPhones.

i just refreshed the router status and the first channel post re errors has changed

different from what they were before and for the T errors im guessing its the t1 t2 t3 t4? if so they have changed also

Hi @byson 

Thanks for posting and welcome to the community.

Apologies for any broadband issues.

You do need a tech visit as your downstream channels are out of spec (some now over 10). 

I'll send you a PM now to assist further.
