I am attempting to get my internet to connect with the latest version of Open WRT. I previously had it working but had to do a factory reset due to the installation process stalling.
I am running OpenWrt 21.02.3 r16554-1d4dea6d4f / LuCI openwrt-21.02 branch git-22.083.69138-0a0ce2a.
It seems there is some setting that is preventing the modem from being recognized within the firmware. I am trying to get "luci-proto-wireguard" to install. Thanks.
Try restarting your modem and your router. You may need to restart your modem multiple times, but that often resolves the issue if the MAC address changed (for example, if the LAN and WAN MAC addresses on your router were swapped in the previous version relative to the newest).
There is a MAC address in the WAN, but no IP. How do I run that command? The SSH access seems incorrect.

IT IS POSSIBLE THAT SOMEONE IS DOING SOMETHING NASTY!
Someone could be eavesdropping on you right now (man-in-the-middle attack)!
It is also possible that a host key has just been changed.

When you flash the router, if you don't keep settings, a new ssh key will be generated. You simply need to remove the old key from your OS's stored ssh keys. On Mac OS, it is the following command:

Still NO internet connectivity via the router. I attempted to install opkg update && opkg install curl to test the connection from the modem to the router.
It still seems like something in the OpenWrt settings of the router is preventing an internet connection. When I initially setup the router (first openwrt flash) with the firmware I followed a set of directions to "add a modem". After doing that I did have wireless internet connectivity.
The OpenWrt default settings are designed for use with a cable modem. There is no need to install or configure anything to have a basic Internet connection through a cable modem.
So whatever you did to "add a modem" was unnecessary and seems to have broken things.
If you look at the router's route table, you should see a route leading through the wan interface to off site. When the cable modem is a pure modem (bridged), your default gateway is a router owned by the cable company at the other end of the cable. Try pinging that IP address.
In this installation. I did not "add a modem". Presently (under interfaces) I have "LAN-- br-lan", "WAN--br-lan", and "WAN6-wan". I don't see a route leading through the WAN interface to off site. I am going to try a new firmware flash now.
