I've been using Linux for decades, and absolutely know better. I bought an ASUS about a year ago when my old router crapped out. I just wanted something fast, and cheap, from Amazon; my main priority was getting access to the internet in the house. Don't feel bad. Dicking around with OpenWRT isn't a priority for a lot of people.

That said, I don't think GL-iNET was around, or I didn't know they ran OpenWRT at the time.

If you have ethernet between the two points, you could do what I did and use it as a WiFi signal extender. I'm not using the COAX (cable) in the house, so I got one of these and ran ethernet upstairs without having to get into the walls. I put the (year) old ASUS upstairs and routed it (via that ethernet adapter) through the OpenWRT router, which VPNs all traffic. I considered putting the ASUS in repeater mode, but I read that it cuts the WiFi speed in half; so instead I did the ethernet thing, gave it the same SSID and password, and devices just connect to whichever signal is strongest.
