I finally got OpenWrt installed and Luci launched. At this point, I was currently using the router connected to a switch that was connected to my original/current router with was connected to my ISPs modem. I enabled SQM and installed adguardhome (didn't do anything after that) just to familiarize myself with Luci before connecting the router to my modem directly. I might also mention, the router is emitting wifi and has a usable internet source. After connecting the router to my modem, and disabling my original router, I could no longer access the internet via the new router with OpenWrt. I could, however, access Luci somehow and was trying to find what was causing the internet to not work.
I used my phone to find people with a similar issue and found multiple forum posts suggesting to change the IP on the LAN to 192.168.2.1 because it was conflicting with the original router. I realize now how stupid this sounds, considering my setup but I proceeded with it anyways. I can no longer even access Luci for my device to revert these settings. Any help would be greatly appreciated.
