I had an intel 8260 wifi card on a gigabyte PCIE card for my desktop. Recently i was having issues where 5 ghz was not visible or not working. I replaced the card with a 9260 and i stgill have the same issue.
The weird thing here is I can see other 5 ghz networks and connect to it if i use a different router (Wifi + Modem) combo.
My primary AP is TP-Link EAP 225 and I cannot see the 5ghz broadcasted by these AP's. The 5 Ghz network from this ap is visible on my phone but not on my PC using intel 9260. I have done the following.
1. Deleted drivers and updated multiple times
2. Created a spearate 5ghz network, changed security settings to include no security.
3. Rebooted multiple times.
4. Reset the AP
Still no luck. I would appreaciate if there is any insight on this issue.
