I have a problem with a network connection. I am not very tech savvy so I'll describe things as clearly as possible. pls bear with me. I have a Motorola SB5100 series surfboard cable modem which I purchased o/seas a while ago. Since it was a cable modem I didn't think I could use it with other internet services. Hence I purchased a Prolink ADSL USB modem to connect to a local broadband connection. I've been using it frequently for over 2 years now and it seems like my internet connection is getting slower everyday. I've heard that Modem routers are better than ADSL modems as far as the speed is concerned. So I want to buy a router. However since I already have this cable modem and it is not very easy to sell it over here is there a way to connect the cable modem to use it as the connection device to internet. I have noticed that the cable modem has one ethernet port.If I can get it connected to the telephone line somehow I can then connect it to the computer through the usb. Or am I doing it all wrong? Pls advice.

p.s Is what I heard about comparisons between router and adsl modem true?

You cannot use a cable modem for an ADSL connection so forget that idea.
I have no experience with combination ADSL Modem/router units. The presumption would be you have one less cable/link in the chain if you use such a device in preference to separate modem & Router, therefore you have less possibility of faulty cable/connections.
Q? You are talking only about a single connection to a single PC. Why would you be looking at routers if you have no other client devices to connect? If you suspect your current ADSL modem is the cause of your slowdown then call your ISP and have them test it. In most cases internet slowdown is a symptom of other issues in the client PC rather than anything related to the ISP, Phone line or modem.

There is no comparison that can be made between an ADSL Modem and a router so whatever you heard is probably falae. They two completely different devices doing two completely different jobs. Sometime the two devices are combined into a single box giving you a Modem/Router. Nearly all of the combined Modem/Routers are ADSL.

The advantage of this as a combined unit is often cheaper than two separate units and there are less cables to worry about and only a single power supply. It makes no difference to the speed at all. That is determined by other factors.

A USB modem is designed for a single computer only. I have never seen a router that can take a connection from a USB Modem. For that you need an Ethernet Modem.

Routers without Modems are neither Cable nor ADSL. They are just routers that accept an Ethernet input. It is the Modem that has to be Cable or ADSL specific. and if you want to connect it to a router, with an Ethernet output.

thank you guys. I think I was talking about a modem router by the sound of it. So it is a router with a modem. But as you have mentioned if the adsl modem has nothing to do with the speed of the internet connection it wouldn't be a good investment for me to buy a modem router.

It would be a good investment to buy a Modem/Router but make sure that you buy one that is ADSL2+ compatible. This will effect the speeds as ADSL technology is improving all the time and ADSL2+ will give you speeds of up to 20Mbs when it becomes generally available. The original ADSL only had a max bandwidth of 8Mbs.
