A budget AC68u
Ok so in TM-AC1900 form, this is a decent router. Nothing special, but decent. The issue is that this won't get Asus' latest and greatest firmware updates, which would add a lot of features, the headliner feature being mesh networking.
But all is not lost! If you are a bit tech savvy, and are able to follow instructions, there are plenty of how tos out there showing how to flash this router to transform it to an AC68u, which uses the same hardware, just with different firmware. At that point, and for the price, this becomes an outstanding router. You can setup a mesh network using multiple flashed ones of these for less than half of what it would cost if you were to buy a plug and play kit.
The instructions I used are here uu uu uu . bayareatechpros . com/ac1900-to-ac68u/ . Note that if you are a linux user, then you likely have all the needed tools to conduct this procedure without installing additional software packages (scp, ssh). Note that if using a more recent linux distro, you will have to add the flag "-oKexAlgorithms=+diffie-hellman-group1-sha1" to both ssh and scp commands.
Happy hacking!
