Router: Something I have to upgrade, though trying for approx a full gig speeds at the modem first. Eying an OpenWrt-compatible one. Looks like the GL.iNet GL-MT6000 (Flint 2) comes with it preinstalled! ( https://www.gl-inet.com/en-us/products/gl-mt6000?country=US )
If it’s something on the shelf at Target, Walmart, you may remain disappointed.
