Modem Router combo or separate units ?

    I've always had modem router combo's for my ADSL broadband, usually Netgear routers. I'm thinking of upgrading to the new 802.11ac standard and looking at some of the products on offer out there, it seems that the standalone router and separate modem are becoming more common.

    What do people think? Are there any major advantages / disadvantages to one over the other? I don't know that I like the idea of two power adapters for two separate boxes having to be plugged in and left running all the time - maybe I'm paranoid.

    Just wonder if anyone has any opinions

    Most of the best routers available don't have modems, also as the technology changes from adsl to Vdsl you can keep the router, leave your lan as is and just bridge the provided modem

    If I did buy a new router, would it be ok to use an old modem/router as the modem for the new router or should I purchase a new modem also?

    You can use the old one, just disable wireless and set it to a bridge, then add the pppoe username and password to the wan if the router so it logs in

    When bridging a modem/router to a router do you need to use a static ip address?

    No, but it's handy to give both router and modem/router an ip in the same subnet so you can connect to both from lan. Pppoe will make the dynamic ip assigned by the ISP appear on the router giving it one hop to the internet as if the bridged modem doesn't exist. Pppoe is a layer 2 protocol, it's basically a tunnel through all bridges and routers to the pppoe server (1 hop), one reason this is used is because it uses much less resources than routing at every device on the way there
