Does not work for me. WAN interface still flipping between up and down. You can also see it at the LED blinking.
Foris still says: WAN port has no link or it hasn’t been configured yet. Your internet connection probably won’t work.
I don’t understand what it even means for WAN to have link. Isn’t that like pulling and plugging the cable all the time? Is my cable defect? I don’t think so since I tried multiple.
I even turned on force link as described in the other thread.
Still everything the same.
Looking closely at the logread, I spotted
turris kresd[4101]: [priming] cannot resolve '.' NS, next priming query in 10 seconds
every time before the WAN interface goes down.
Could it be a DNS problem?
