DSL to ADSL ?

PeN · 25 Jul 2007 at 19:55

Hey Folks

I have a telewest cable connection in my flat, It runs a 30 foot cable from the hard wired point in the livingroom to the Cable modem in the kitchen (motorola SB5100).

I have been given a new ADSL wireless BT business hub BT2700GV 2wire router, and am hoping there is some way to hook this up to my DSL connection, so i can wirelessly connect to my PC in the kitchen.

Is this just a no no... or is there some king of adaptor to convert dsl into adsl...

Cheers

not sure if it will , i know in the past a cable dsl modem was different to a bt adsl modem. i went to purchase a cheap adsl modem but turned out to be a dsl cable modem (luckily the shop told me before i bought it)

Though if you do get it working, with that particular model of bt router its locked down to BT. You have to really jump around hoops to get it working! (BT have them butchered so that if it connects to the internet it checks your username against the serial number and if its different it resets it!)

Though there is ways round that (Google search

Had a look at the hacks and there will be one i can use to point the checking service elsewhere so that it does not constantly reset the username and password, but i need to know if i can connect the 2 routers with rj45 cable or usb and then connect to my pc to set up the router in the first place.

Dont know if this is just not possible, or if im just being stupid

ADSL is a form of DSL. The reason cable routers are referred to as cable/DSL routers is because they can work with a DSL line (this would include SDSL and ADSL as they are a form of DSL - cable isn't) with the use of an ethernet ADSL modem.

It's not entirely clear whether you have a router for your cable connection already or not. You will be able to use the ADSL router as a switch/wireless access point only, you will not be able to use it for routing purposes. To do this just ignore the ADSL port on it totally, give it an IP address on the same local range as your existing network (ie. if you're 192.168.0.x then give it an IP in that range), disable DHCP on it, plug an ethernet port into one of your router's LAN side ethernet ports and you're done.

If you don't have a cable router already then forget it. You'll need a cable router.

Looks like your after a wireless repeater without any built in adsl modem. Something like http://www.overclockers.co.uk/showproduct.php?prodid=NW-052-LS

I use the 2wire from BT but it will probably be pretty complex getting to work bridged with your cable modem and even then the BT locks on it might not let you. If your after a repeater a bit cheaper I have a buffalo one you could have.

This is correct, but usually you won't find a router (marked as DSL) that supports SDSL and ADSL (I'm sure there is one out there). In other words just be careful.

A "DSL" router will do SDSL, ADSL (over both POTS and ISDN), VDSL, cable, satellite, anything you can throw at it - because it doesn't have a modem built in. It'll work on anything that can connect to the router over ethernet.

So your saying a "DSL" router is just a regular router that *can* be connected to a modem or another router which has a modem that has a ADSL (or whatever). IMO that is very misleading, especially to say someone who doesn't know too much about networking.

Ethernet (n): something used to catch the etherbunny.

I found that very funny...

Yes.

Not really - it isn't advertised as coming with a modem, and it will work with both.

Yes and as tolien says, it's not misleading because they aren't advertised as coming with modems. That's just how they're sold
