I searched the specifications and it says it supports 5ghz wifi, I entered the wifi information manually nth times yet it says it can't connect. it connects perfectly to 2.5ghz wifi. Does it support it or is Samsung just lying?.
When searching for the specifications by model number it's important to include the four characters before the "AU7000" and the four characters after it. Samsung makes multiple versions of the AU7000 so it's important to search by the complete model number as there can be variations in the specs.
