Hello
I have an issue with my wifi, it's not reliable. There is no problem with my laptop, or any other devices on my network, but my NanoPi Neo is disconneted after a few hours. It can stay alive for an half a day, and after it become unreachable.
As I have no other connection to my NanoPi it's a bit hard to establish what appens. But if I unplug the USB Wifi dungle, and replugged it the link come back.
Doing a ping to the NanoPi, I see regular "Request timeout for icmp_seq" - every 20, 50 or 100 request, it depends - and sometime the request time is abnormally huge: serveral seconds.
The config has bee done with nmtui, the name has been left as proposed (wlx00b819aa5f7). It's a static IP, Gateway is y router, and the DNS server has been input manually based on my router data.
iwconfig output:
