[SOLVED] NanoPi Neo wireless connection

Post by Gord_W »

When trying to set up a wireless dongle on NanoPi Neo I ran into a few problems. I can't get the wireless working regardless of what I try. dietpi-config seems to have some issues too.

1. Netplug and iproute are not on dietpi by default. Therefore if you are trying to set up wifi and don't have an internet connection then nothing works.
2. When trying to activate the wifi through dietpi-config with ethernet internet connection, first time was to download Netplug an iproute then second try was to enable the connection. Then things stalled. ssh connection broken

I see that this is wlan0. See below wlan1 and wlan2 are also used.


3. Log back on. iwconfig says. The ESSID and password I entered earlier now gone.
root@nanopi:~# iwconfig
lo no wireless extensions.

tunl0 no wireless extensions.

wlan1 IEEE 802.11bgn ESSID:off/any

eth0 no wireless extensions.

Here it is now wlan1 that is being used.



4. 3rd try with dietpi config.
Ethernet : Available | Enabled | Connected │
│ Wifi : Available | Enabled | Disconnected

Going into wireless the SSID and Password entered earlier are there.

Try to set Country code. The currently set one is 00.
I live in Canada so tried CA

There was a message on the screen while it was setting the country code, but it was too fast to catch before the menu came back up

Why is there no country code setting for Manual IP Setup??

5. Forget country code and see what happens with apply wifi settings.

What is this above. Says it is renamed, but it is not.

Is there anything that I can update?

Hi Gordon,

Thanks for the report.

I have the same adapter and got the same results. Scanning wasn't working for me, so replaced kernel module with one from RPi, fixed that but all other issues still remain.

Non-functional wifi modules, unable to set country code, unstable WiFi: Seems to be a common issue on all ARMbian images that we use, at the moment.

I'll rebuild the NEO image today and re-test, hopefully the ARMbian devs have fixed those issues since then, if not, i'll create a ticket for these issues.

Gordon,

Appears ARMbian are aware of current WiFi issues on their images: https://github.com/igorpecovnik/lib/issues/558.

As we use ARMbian as the base for NanoPi NEO image (and therefore, their kernel, firmware and modules), I can only suggest you contact ARMbian and report your issues directly with them, as it is out of our hands at the moment.

Do you use the Ubuntu or Debian image for Dietpi?

Debian, built with ARMbian build tools.

I've sent you an email, but i'll also post here.

We have created a 4.9 kernel image, wifi appears to be working, can you please test the image and let us know results?

That fixes the wifi and i2c errors.

There is an issue with software installation that I have sent you a separate message.

I think that this thread can be closed.

Thanks,
