My Asus laptop will only connect to my 2G wifi and not my 5G.. Why?
Wrong term, you’re thinking of 2.4ghz band & the 5ghz Band. You’ll have to make sure your laptop is 802.11g & 802.11n compatible, as it may just have a incompatibility with the 5ghz and asides from that I’d vote for a reconfiguration on the router and to double check alot of that stuff.
