    TD-W8970 "no carrier"

    Model :

    Hardware Version :

    Firmware Version :

    ISP : [/COLOR]

    Region : Poland

    Model : TD-W8970

    Hardware Version : V3

    Firmware Version : 0.9.1 2.0 v0035.0 Build 160816 Rel.35740n

    ISP : Orange

    OS: Linux Manjaro

    Hi, I've recently bought a new router as above, because my old one had only one working LAN port (I need more of them). Now my LAN connection is awful, it constantly disconnects. I was googling for a solution for a few days now, and initially I thought it's a linux problem, but now I'm sure it's not a software problem, because when I switch it back to my old '1 LAN-port router' everything works perfectly. Log from my NetworkManager looks like this (a snippet, all day long it's a loop):

    Did you setup the TD-W8970 correctly and if there is a WAN IP address on its status page? How about the wireless connection or the LAn connection on another PC?
