I have purchased the ASUS PCE-AC68 and it clearly says it picks up dual band wifi the 2.4 and the 5 GHz connection, but after i installed it it only picks up the 2.4 GHz connection, whereas my other devices they all can pick up the GHz connection, so clearly its not a router issue after i did some research someone suggested that i change the channel on my router, i tried that, now it can pick the the 5GHz connection but at very slow speed! the 2.4 GHz was faster than the 5GHz! I contacted ASUS they said most probably its a defected component and ask the seller to exchange the product, i did that and he gave a new one and i tried it at his store it worked perfectly and could easily pick up the 5GHz at his store but again the new one Can't pick the 5GHZ connection at my home, i contacted my internet provider they said its my PC issue and their router is working fine.
