How issue presents itself: #1 Hi all, I do have trouble with my Asus Router seems one of the Lan port isn't working. The actual software version 34.386_46065-ge51f2dc. Any idea how I can come around that problem? I do have Zenwifi xt8 which is connected via LAN but continuously losing the network connection. Initial router setup detected that and took me straight into wireless network setup. I setup my 2.4 and 5GHz networks and I can connect the Internet through them with no issue. The problem is that I cannot connect via ethernet with any of my wired devices. My network is mostly wired, I only use wireless for devices that don't have an ethernet port. A long and trusted temporary Ethernet patch cable could help rule out your Ethernet cabling, which is naturally suspect. Disconnect all LAN ports before testing with the trusted cable. Are all router LAN connections listing as 1 Gbps, if they should? For me the issue was that I have enabled only access for the router, so it needed also the correct port number.
