Are all "routers" also modems?

Hmm. Ok. I had better buy a modem then! Any recommendations? I want it to be super fast, and super stable! The Motorola ones, now Arris, seem to get good reviews but they only seem to exist in the US?
 
ah right, so BT do everyone? Man it makes me uncomfortable not being able to choose my infrastructure!

I currently have an Netgear N600 - is it possible to just isolate that as a modem for now?

What are the benefits of total standalone modems over the netgear as a modem (even when connected to the asus which would be the router). The draytek site mentions this but I dont really understand it:

"The DrayTek Vigor 120 is an ADSL modem with an Ethernet connection; it is not a router but a true ADSL Ethernet Modem. By providing a PPPoE to PPPoA bridge, the connected device (firewall, router or PC) can log into the Internet (your ISP) directly and have full control over the ADSL connection - that makes the Vigor 120 a unique product. You can connect any device to the Vigor 120 which has a PPPoE client facility, which includes PCs, most Ethernet-WAN routers and the Apple Airport/Time Capsule™ products.

Other ADSL Ethernet 'modems' use workarounds to get a public IP address 'through' to your secondary device/client, requiring non-standard operation and complicated dual-stage setup (modem logs in, router routes) but the Vigor 120 provides the secondary device with a real routed IP connection and the ability to fully manage the connection, making setup easy. In most cases, the Vigor 120 needs no setup or configuration - just plug it in and set up your PC or router. All login/ISP details are entered on the connected client device, not the Vigor 120. The actual connection to your ISP is still PPPoA (unlike other modems which only provide PPPoE native bridging), which is the unique feature of this product and makes it compatible with all UK ISPs, where PPPoA is used as standard.

This method also differs from using a regular ADSL router which logs in itself and then uses NAT or multiple public IP addresses to create an onward client connection for your secondary device; that is not IP Address thrifty, or introduces secondary NAT compromises. With the Vigor 120 bridge/modem, you get a true single public IP address (or multiple, if you have them) straight through to your firewall/router, which also has complete control of the ISP connection."

Modem is just Modulation Demodulation, the "sign in settings" for your ISP are here, this is converting an analogue signal form the ISP to a Digital signal for your router.

In the UK most Home internet other than virgin media and the new FTTC was provided with a spliter in the phone socket and a rj11 into your "router" into, this was an ADSL2+ modem + router in one box and usually PPPoA connection for the ISP account details

With Virgin media or any FTTC product they provide a modem during the installation, although now some of the VDSL isps (sky bt) have a router modem combo, it does your VDSL over rj11 again, though they can be used with an external modem too.

In theory you could have seperate boxes for Modem, Gateway, DHCP, Switch, Gigabit networking, Wireless networking... this was the case from some crazy setups.

We mostly are used to getting a router (Modem 4*ethernet + wireless) with our Broadband since 2006 as they are kinda required to make it work. In theory you never have to use their stuff BUT it may be in the contract that you do.

N600 is not limiting the search enough with my google fu, so I have found multiple models for ADSL and PPPoE so Cant advise on that.

Need to know what ISP set-up you have but in general on ADSL2+ (up to 24mbps) the ISP provided router has a modem that is going to be within 0.3snr of any other you get in my experience. If your going for fibre from anyone soon you can use a different box for the modem but the white one openreach provide is what I use with my Asus RT66U N router, works a treat.

I then got FTTP and that has a ONT (optical networktermination) that plugs into a fibre "modem" not sure what it really is called, late to go downstairs and check. Sufficed to say I checked the settings (same as using a VDSL modem, PPPoE with bthomehub default user name with no password)

P.S. It's late and I have used this as an excuse to waffle, I know somewhere I said modem is where ISP sign in stats go, thats wrong, but I will format later :P
 
I think I am getting it now. Id rather not buy a standalone modem now as its likley I will get fibre in the future, and hopefully I can use my N600 for now in the mean time.

The exact model is DGND3700. Can I run it as just a modem and leave the routing to my new Asus? Thanks!
