Hello PlayingMuted,
I had the same problem and found this thread.
Just wanted to let you know that i found a solution for that.
In my case i am using the app "create_ap" from: https://github.com/oblique/create_ap
which is basically just a script setting up your hostapd,dnsmasq and interfaces.
With this command from the doc it was not working:
sudo create_ap wlp3s0 enp2s0 MyAccessPoint
I could open and start the AP but i couldn't really connect to it because no device ever got any IP from my AP.
The solution was to start in N mode instead of G mode, which is default in hostapd.
Following command worked for me:
sudo create_ap --ieee80211n wlp3s0 enp2s0 MyAccessPoint
But i think you can basically just change your hostapd.conf file and use this arguments:
hw_mode=g
ieee80211n=1
ht_capab=[SHORT-GI-40][HT40+][HT40-][DSSS_CCK-40]
