Hi guys,

I am trying to use TP-Link dongle WN722N v3 as an access point . I am using Nano Pi Neo Core EMMC with expansion board running  Armbian Buster with Linux 5.3.9-sunxi . 

The device can detect wifi signals nearby as seen on nmtui in managed mode  . I followed the instructions on https://forum.odroid.com/viewtopic.php?f=52&t=25472&sid=84d2b8f1e7ad477e9907591eb7fb030d to configure as access point . 

However , I get an error every time like this . 

root@Cyborg:~# nmcli connection up HotSpot ifname wlx503eaaa2df7b
Error: Connection activation failed: Connection 'HotSpot' is not available on device wlx503eaaa2df7b because profile is not compatible with device (the device does not support Access Point mode)

Output of dmesg | tail -n 20 on inserting the dongle .

I know the dongle works  because I used it on a Nano Pi Duo running FriendlyARM's running Ubuntu Linux kernel version 4.14.0 . 

 

I am really confused . Is it a kernel issue ? My main intention is to use some GPIOs using Wiring Pi and run an apache webserver on it .  I want to use the dongle to serve HTML pages over a hotspot . Any help is appreciated .

It's a driver - from 3rd party hardware Armbian have no resources (time, people, money) to do anything about - issue. What you can do beside using better dongle? Blacklist existing driver and try to build some other from the internet. Everything in this regard is available on Armbian: compiler and headers.

Moving to general section since it has nothing to do with Nanopi H3.

You could better use official way - you have way more chance to success:

I think you will not see AP (while STA works normally) on this chip unless you fix the driver. IIIRC this function is simply broken / not done yet.

Hi Igor,

I tried using armbian-config . It downloaded hostapd and hostapd-realtek but it could not configure it as an access point .

Do you suggest any dongle for my application(low bandwidth , only for short distances , access-point) . I tried the 2$ Ralink adapter and TP-Link WN722N . 

This time maybe I'll buy something other than Realtek

For AP use Realtek 8811 / 8812 / 8814AU. They works the best!

This works if you driver works properly. If you don't use 2$ shit
