Do i need dual band? my phone doesn’t even pick up any networks in my (rural) area,
Titleist Vokey SM5 Wegdes, so the 2.4Ghz frequency should be pretty clear,
Titleist Fers MB 714, although people suggest 5Ghz for appliance interference purposes. 802.11 is the standard, but do i need N or G? what speed? what about gaming? (i occasionally play modern warfare online as well). I guess i am willing to spend a few extra bucks to future proof myself,
