I tried everything with ( tp-link archer c7 v2 ) to make the device recognize the wan ip if I changed from source net ( CPE modem ) without any solution till now and found many others in the forum have the same problem and nobody found a solution even with the trivial multiple releases of openwrt - It has no value in my opinion -
Hotplug not working during Interface Up/Down , I unplugged wan port and the device not recognize at all , even not recognize the new ip from the modem when I changed it .
I have about 30 diff-rent models of routers and always found openwrt fundamental defects in every model with every release
openwrt is unable to be like the original factory software.
Soon I will tell with confidence that openwrt is full of defects ( so
buggy OS in all versions till now )
Unfortunately, all its many releases have the same flaws in every device.
What is the benefit of the many versions in succession and without any fundamental repairs for defects in devices that work fluently with their original factory software .
Time wasting + frustration = openwrt
