Hi, the early Gen1 VodaTV has a reputation of mysteriously dropping connection, the fact that you can access Netflix or YouTube at the time indicates its unlikely to be a problem with your network, but a known issue with the VodaTV.
After the RWC I understand the VodaTV Gen1 will get a firmware upgrade to bring it up to date with the Gen2 model, this fix's these issues.

Edit: One final note, I personally would run a mile than use an Asus router.
it's perfectly fine when you don't use the smart features or try to reboot the router ;p
