I have two Linksys routers broadcasting a total of 4 SSIDs; 2 of which are 2.4GHz and the other 2 are 5GHz. My MacBook is located on the third floor of our house, about 10 feet away from the router on this level. It connects to the correct router, however it chooses the 2.4 GHz signal over the 5.0 GHz signal. Does anyone know of a way I cam force my MBP to connect to the 5GHz signal without giving the 5GHz signal its own SSID? Every other router in my neighborhood uses 2.4 GHz so there is quite a bit of interference. When I use the 5GHz signal, I get exactly the speed I pay for from my ISP, as opposed to about half of the speed when I'm connected to 2.4. Any insight is greatly appreciated!!
