Does anyone have any experience with 5GHz Wi-Fi? I'm contemplating buying an adapter AC for my PC but I'm not sure if it would be of much use given the range. My router is approximately 10-12 meters away from the PC. Windows claims that I am receiving 5 bars of signal on 2.4GHz but the speed is limited to 2.5mbs So as an alternative I'm considering an antenna instead.
Just for reference my router is a TP-Link Archer C7. Please no "Why don't you use a cable?" suggestions, if I could run a cable I would.
