And there we could not determine why ports 3 and 4 on that AVM box will not work, as in, no connection. @psherman was very engaged. We finally, abandoned it, with him asking I reflash back to the manufactures firmware and check that the ports work.
Well, I simply got an older yet similar AVM box, 7360, and installed the latest Openwrt firmware on that. And guess what; the exact same problem. Hardware ethernet ports 3 and 4 do not work, as in, plugging an ethernet cable in them gives no connection at all. But hardware lan ports 1 and 2 work.
I have not done ANY configuration to the router after the install. I simply installed openwrt, went to luci, clicked login and shut it down. As I now tried to get it online, when I plugged the cables into ports 3 and 4, I get no connection. But I do on ports 1 and 2.
So, can someone who knows more than I do please look into this. Perhaps it's a bug. This is the second such box with the exact same problem. If you want more detailed explanation, then please follow the thread I posted above.
Meanwhile, I need now to configure one of these hardware LAN ports (1 or 2) to get online. Help!, or same as with the other router on the link above?
See picture below, please. Even though we 'see' a connection on LAN hardware port 4, which is connected to an upstream router to the Internet, we get no Internet connection. As well, when that port is connected 'locally' to the computer, as noted earlier, no connection to the laptop. And the ports that work match; hardware number 1 matches to Vlan port 1.
