-- Red (VM SH2 AC Beta tester) Running on 200Mb VM service with SH2 AC in Modem Mode, with a ASUS RT-N66U router. With this setup I get Fantastic WIRED and WIRELESS Signals in my home. I dont work for VM. But I work in IT, and I know my tech. My advice is at your own risk.
I'm sorry to hear you couldn't connect to PSN on Saturday. Can you let me know if this is ongoing? There did seem to be a couple of different issues over the weekend, although it's not clear if anything is ongoing still.
If you could let me know I'll gladly look into things further if necessary.
