I'm new here at the Armbian board. I operate a self made house automation based on a Raspberry using a self written PHP server and Homegear.
To have a better wireless connection to a differential temperature sensor, I built a Homegear Gateway based on a Nano Pi Neo with Armbian OS and a 868 MHz CC1101 module.
For the network connection I use a Realtek USB WLAN NIC (Realtek RTL8188EUS-Chipset). Most of the time the gateway works.
But around 2-3 times per week the gateway hangs and I cannot log on anymore. A hard restart by unplugging power is required.
The only indications I find are 2 dumps of the RTL8188EU driver in kern.log. Check the 2 dumps at the far end of the armbianmonitor output starting at 24.009211.
I already built & installed the 8188EU(S) driver from here and here by myself. But unfortunateley without success.
Anybody any idea whats going on with my gateway?
Thanks a lot for help.
Update: Just had another crash. Maybe someone sees the reason here.
Update: 19.09: Since I cannot create a new answer (what's the reason behind "You have reached the maximum number of posts you can make per day"?), I add it here.
I just ordered a new NIC with a Ralink 5370 Chipset . Should arrive on monday. I operate the gateway with LAN until then. I'll report how it works with the new NIC.
I don't understand why the download pages for boards where images are considered 'beta' link to outdated images but here you go: https://img.armbian.com/nanopiair/archive/
Nightly builds with 4.9 should be avoided by end users. I personally tested WiFi with the Air in an area where 2.4 Ghz band is close to unusable and after disabling PM (use google search link in my signature for 'h3consumption wifi') it was at least multiple times better compared to the usual USB Realtek crap (8192 and marketed as 300 Mbit capable). But as already said: if you run in trouble with 2.4 GHz and live in a city the 'environment' is most likely to blame and of course the try to use el cheapo WiFi crap that is on all these cheap SBC these days.
