Gaming over WiFi can sometimes create problems, but usually the latency overhead is tiny, around 7ms, although that will go up a touch if other people are using wireless at the same time. On account of radio signals traveling at the speed of light, that overhead is merely the processing of the wireless signal, and that's trivial unless it is compounding other more serious latency issues. The VM hubs don't offer any QoS capability, but any decent third party mesh or router will, and that will keep wireless latency low.
But if you are having more extensive problems it is probably a broadband issue. Connect to the hub at http://192.168.0.1/ That should pull up the log in page for the hub. But don't log in, just click on the link "Check router status" That'll bring up a window with five tabs. Open the Downstream tab. Select all the text (Ctrl-A if using a keyboard), copy it (Ctrl-C), then paste it (Ctrl-V) into a reply here. Post that, do the same for the Upstream and Network log. You'll get an error message when you post the Network log, just click on "post" a second time.
Then we can check for any obvious problems with power, noise or error counts.
