[OP2] How to get Network to work again

[SkipperEarly]

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

pi@op3plus:~ $ ls /sys/class/net
eth0 lo wlan0 wlan9
pi@op3plus:~ $ ls /sys/class/net/eth0
addr_assign_type dev_id link_mode power
address dev_port mtu proto_down
addr_len dormant name_assign_type queues
broadcast duplex netdev_group speed
carrier flags operstate statistics
carrier_changes gro_flush_timeout phydev subsystem
carrier_down_count ifalias phys_port_id tx_queue_len
carrier_up_count ifindex phys_port_name type
device iflink phys_switch_id uevent
pi@op3plus:~ $ ls -l /sys/class/net/eth0
lrwxrwxrwx 1 root root 0 Nov 24 09:43 /sys/class/net/eth0 -> ../../devices/platform/soc/3f980000.usb/usb1/1-1/1-1.1/1-1.1.1/1-1.1.1:1.0/net/eth0
pi@op3plus:~ $ ls -l /sys/class/net/lo
lrwxrwxrwx 1 root root 0 Nov 24 09:43 /sys/class/net/lo -> ../../devices/virtual/net/lo
pi@op3plus:~ $ ls -l /sys/class/net/wlan0
lrwxrwxrwx 1 root root 0 Nov 24 09:43 /sys/class/net/wlan0 -> ../../devices/platform/soc/3f300000.mmcnr/mmc_host/mmc1/mmc1:0001/mmc1:0001:1/net/wlan0
pi@op3plus:~ $ ls -l /sys/class/net/wlan9
lrwxrwxrwx 1 root root 0 Nov 24 09:43 /sys/class/net/wlan9 -> ../../devices/platform/soc/3f980000.usb/usb1/1-1/1-1.2/1-1.2:1.0/net/wlan9
pi@op3plus:~ $

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.
