I've struggled to find anything on the web about my problem, so here goes!
I've just purchased an Asus PCE-AC68 Wireless NIC to use the 5Ghz capability of my Netgear DGND3700v2 router.
I have tried changing the channels between 36 and 44, and the speeds between 145mbps (also tested ch40 on this speed) and 300mbps, but can't get the thing to find the 5G SSID.
I jumped in the device properties, tried setting the 802.11n preable from auto to mixed mode, tried enabling beam forming, don't understand the rest so don't want to ruin anything, but it's still not finding the network.
I have two other 2.4Ghz networks running on the router, but can't see how they'd get in the way as there's separate setting sections for each of those.
Also updated the firmware on the router.
The router is physically one room away, the signal I guess either goes around or through a few cupboards.
I can't imagine setting up a 5G network can be so much harder than a 2.4G one?
Anyone with some experience with this stuff? The Asus site is crap for these issues and other forums are mentioning other settings like WiFI band disabling which doesn't seem to be an option I've got.
