I had a strange problem where I got scammed and overpaid for my crappy old Wifi card when building my PC years ago.
Up until recently, my solution was to use an old micromax A109 in USB tethering mode. About six months ago, it could not handle the overcharge and the battery ballooned up. I have been living with it since.
I got sick of it today and installed OpenWRT on an Archer C5 v4(the #actfibernet one). I sent this to connect to my home Wi-Fi network as a client, switched the default IPv4 to 192.168.2.1 to not conflict with 192.168.1.1 and most importantly, enabled IPV4 masquerading in firewall settings.
A quick restart and now it acts as a Wi-Fi to ethernet bridge thing!
Disclaimer: while I took a screenshot with my Linux laptop for testing, this is going to be placed behind my Windows PC.
