Error: unknown configuration item 'ieee80211ac'

[Jorge Magno]

Hello,

I was here trying to use "ac" mode, but the stations weren't communicating. So I ran "sudo hostapd mn****_ap1-wlan1.apconf" to check the problem and, I got the following error return:

Line 10: Hello,

Failed to set up interface with mn****_ap1-wlan1.apconf

Failed to initialize interface

I wanted to know the reason for the error, as I did not see anyone having a similar problem in the research I did. Besides, I didn't find any example of using the "ac" mode and, I didn't know what the problem was, after all, I installed the mininet-wifi a little over a week ago.

I'm sending the code also, in case you have any questions. However, this is a simple scenario.'

Which version of hostapd do you have?

The command "hostapd -v" returns me:

hostapd v2.10-devel-hostap_2_9-2326-gf18433760

I'm pretty sure you have a build that does not include the 80211ac
