This is probably a very isolated issue, but I've got a couple brand-new ThinkPad T490s laptops with Intel 9560 WLAN cards in them. For whatever the reason, they have issues connecting to some of my 2802i/e APs using 802.11ac. I have to switch the cards to use 802.11n in order for them to utilize 5Ghz at all.
The weird part is that they'll connect to some of my 2802i APs using AC just fine, and not others, and I can't figure out why. Each of my APs are part of the same AP Group, and use the same RF Profiles. None of the other devices that we own with AC WLAN cards have any issues connecting using AC. The drivers for the Intel cards are up-to-date, and the APs are running 8.5.140. The laptops are running Win10 1903. Nothing in my logs seems to give me any indication of what could be going on.
I'm assuming that this is most likely a driver issue with the Intel cards, but before I give up on trying to make this work, I was curious if anyone else has run into this, or something similar. Is there anything in my controller config that could possibly cause this to occur that I should be looking at?
