dual band N7260 in my HP is working well with 17.13.0.9 drivers dated 09/29/2014 so far. no issues. i didn't change any options; U-APSD support etc.
I have only connected to 2 different routers, both are Asus routers running Merlin software. well see what happens when i travel with it, last time was rough. I carry a couple USB wireless adapters with me.
