I just bought a new D-Link dir 865l, configured it, both 2.4 GHz and 5 GHz frequencies. But I have a small problem.
I am unable to see or connect to the 5GHz connection on laptops, if I don't plug in the Wireless AC Dualband Adapter. On a Macbook or an Ipad it is visible and I can connect to it, but not on laptops or other devices that have Windows or Android as OS.
I don't get it. Is this normal? Do you need the adapter to be able to use 5GHz connections?
