The specs below indicate that your laptop has built in wireless ability (although it's the old "B" version)
If you purchase a wireless router / modem combination, it should work with your machine.
You need to check with NTL for compatible cable models first though.
Then, when you have the kit, connect as per the manuals instructions, then, after you have setup the router / modem your lappy should be able to see the connection. If you have problems, post back..... Remember, you must have a cable compatible wireless router / modem combo for this to work.
