I am currently using a Arris TM822G (modem) and Linksys WRT54GL (router), which is giving me tons of issues, the language will refuse to change back to English no matter what I try, port forwarding doesn't work properly if at all, and the interface is a bit dated compared to my Netgear CG3000D, I want to use my CG3000D as my dedicated router in place of the Linksys one, but I am wondering if this is possible or practical, or even just use it as both the modem and router, I tried right now and when I switched the cable over to the CG3000D, i was not getting signal, does anyone know a fix for this, or any possible solutions?
