I have a HP DV7T-6XXX CTO notebook running Windows 7 x64 that has the wifi card upgraded to the Intel Dual Band Wireless AC-7260 for the purpose of being able to connect to my Motorola SBG6782-AC Dual Band router. The latest drivers have been downloaded and installed from the Intel website. There is no problem connecting to the 2.4 Ghz network and the 5 Ghz network IS visible as an available network but, it will not connect to the internet on the 5 Ghz band. Pinging the router when "connected" on 5 Ghz confirms connection to the router.
I have tried restarting my router, removing all security settings from both the router and computer and have deleted the 2.4 Ghz connection and then set up a new 5 Ghz wireless connection and have also changed adapter settings to "Prefer 5 Ghz" -- all with the same results.
I have contacted Motorola Tech Support and, after almost an hour on the phone with them, the tech was stumped as well so, I'm hoping that someone on here will be able to tell me what I have overlooked. Any suggestions will be greatly appreciated. acC network problem
