Why would the would-be hacker need access to the router settings? I can't think of anything worth changing there, these routers don't have any extra features.
The usual illicit use is to point an antenna at a router and use it from afar (well, no more than 100-300m, line of sight and preferably no obstructions).
In which case it makes more sense to just get a prepaid SIM card, set up a phone as a VPN in a location far from you and route traffic through it. It's not more complicated than bruteforcing a WPS PIN or WPA2 password. That is, if you can't just get a VPN without using any ID.
