*EDIMAX adapter sees my 2.4GHz network but not the 5GHz network. My internal adapter can see my 5GHz band as normal. Internal adapter is disabled when trying to use the EDIMAX. I have no idea where to go from here.
Try a lower channel such as 36,40,44,48 in the 5GHz range some client adapters have issues with the higher frequencies and they are also affected by the DFS / TPC and SRD protocols.
