Here's my setup: Hardware: Intel Wireless 7260, Driver: iwlwifi, Kernel version: 5.3.0-42-lowlatency, OS: Kubuntu 19.10
So whenever I try to create a WLAN AP using the A band, the operation fails.
After some searches I fount this page: https://vincent.bernat.ch/en/blog/2014-intel-7260-access-point
Basically it says I need another device, like an Atheros device.
Question: Has anyone succeeded in creating access points in the A band using a WLAN card for a laptop? Which model is the WLAN card? Also, if the firmware of the WLAN card is the issue, is it possible to modify it?
Any advice / help would be appreciated. Thanks in advance.
