This is a most excellent place for technology news and articles.
I have always had my own router. What is bridge mode? Can I do that?
Bridge mode disables the router in the modem; if you have an admin account on the modem you should be able to enable it yourself; otherwise you need to get your ISP to enable it. It will turn off all the firewall and WiFi features on the modem.
I'll check that out, thanks
