Recently my home network has been wigging out hardcore. Everything will be fine one second, and the next, i'm not able to connect to the internet. The actual network will be connectable, but forget trying to watch a show or check your email. It just recently happened while I was playing an online game, and after testing my connectivity I found out the there wasn't a definable DNS server. Is this an error on my end, or Xfinity's? I've restarted the moidem, checked the cables, and have had refresh signals sent from Xfinity but nothing seems to work.
Is this with a WiFi connection ? If so, for a test, does a computer hardwired directly to the router / gateway device with an ethernet cable have the same problem ?
