[OP2] How to get Network to work again
#1
RP3b+ with Moitessier. Have suspicion that my internal wlan modul is not working anymore and added a wlanUSB. For the i/net and the headless mode I am currently connected by ethernet cable and switch/router.

can't really reproduce what all I tried to get the op wlan working again.
Have de&re-installed OPnetworking but now when starting OPnetworking I see just the hourglass for ca 10sec and nothing else (no network dialog openin
I add the iwconfig and ifconfig files, any other logs I should share to get help?

It seems an encoding issue. I think I can fix it on next update today or tomorrow.

Thanks sailoog for a great support - would wish commercial developers to be such responsive!
Will report back.

Try openplotter-network - 2.0.6-beta and report please

When you buy any proprietary software or hardware you are tied to the company and they know that. When you "buy" opensource stuff you are free to go, so I have to take care of you Wink

OK

If you take the USB wifi device it should work, try it.

But we need to know what produces this error. Plug in the USB wifi device again and type:
ls /sys/class/net
then try this for every value you get from the previous command:
ls -l /sys/class/net/eth0/
ls -l /sys/class/net/wlan0/
...
and send me the output.

have now made a further test : I changed also the usb-WIFI and now open-network does start
for infor see below:

I guess this confirms, that my onboard wlan is not functioning any more but I can configure a usb wlan.

had to change the xx.xx.xx.xx onboard to the ....usb (just a little remark - when changing the SSID and password info gets overwritten to the openplotter defaults - would be nice to keep the option to remain with previous setting)
Will try to understand why mac addresses are taken on left network panel and logical names in access point settings and how to match them.

Thanks sailoog, for your great help.
