Well I've moved house (a massive tale of woe), took all my kit including the Superhub 3, same pfsense firewall I used before, unifi ac lite and all switches etc. Now getting what I can only describe as 'deadspots' on my connection for the whole household. They usually kick in every 15-30 minutes and last around 10-20 seconds - during which the internet connection doesn't respond at all. If I'm gaming (BF4) I get kicked off servers, if I don't get kicked off - the whole game just locks all movement for 10-20 seconds - I have the FPS monitor running, the game hasn't crashed, just waiting for network data. I did notice some issues when working from home too - my laptop on wifi had similar issues with remote connections via RMM to servers. Looks like its another call to Virgin. I've removed lots of redundant coax connections to various rooms, so now have a single entry point with a single cable to the cable mode (through an attenuator). Signal levels look fine, SNR and power levels on both the upstream and downstream look fine -complete pain the backside.
