Starting a thread here as I was advised in this thread yesterday that I appear to have noise on downstream channel 13.
I upgraded from my rock-solid Vivid 200 recently (SH2ac) to Vivid 300 (SH3). My old SH2ac was in modem mode, with my Asus RT-N66U as router. Although all seemed fine in router mode (way over 300 meg when it was tested during the day on installation), performance hasn't been so good in modem mode - generally 20 meg or so.
Re: Speed and other issues since upgrade to Vivid 300
Nat, could you or someone in the Forum Team respond to that post please? It's been nearly 2 weeks since I posted and a week since any response; SNR on channel 13 down to 24.1 today and speed suffering as a result - noticeable buffering in streaming (Netflix).
