Joe2812,
I moved to wireless a few weeks ago after BT upgraded my line to 2MB. I used a Netgear DG834G which worked straight out of the box with the BT link. (main reason for changing my old Draytek router which was a solid piece of kit was that the BT supplied modem was the only one did not work with the old Draytek
) You don't need the USB modem that BT send you.
Grow45 - Yes there are equivalents for Broadband. Take a look a
www.broadbandbuyer.co.uk, plug in the type of connection you want and it'll tell you the choices.
My laptop has a built in the wireless thingie so I need a router and a dongle type whatsit for the PC.
I have Centrino in my laptop which offers Wireless without having to add anything. However in my case it is the slow "b" spec which runs at 11MB/s (which is still 5 times faster than the BT line so no problem). Just don't spend hours like I did trying to work out why it's not running at "g" spec 55MB/s
Eldest son bought an eBuyer own brand PCMCIA card for his laptop, £20 + p&p, and it worked absolutely fine. Also saw another known brand card in our local Tesco for £25 so would have been just as easy to pick one up there.
With the router in the back bedroom, both of us can work out at the bottom of the garden or in the lounge on the opposite side of the house.
Don't forget to turn on security - I went to WEP on the Netgear. Nothing against my neighbour, but I can see his wireless network from my desk and thus he can see mine.
Have fun
