I got a
TRENDnet TEW-432BRP, with a matching USB Adapter for my Laptop.
I don't use it that often anymore but it was a good buy, I got it from B&Q think it was ?125 with the USB adapter. They do a matching PCMCIA Card as well.
This is a good
forum on all things cable modem, helped me when my laptop kept losing connection to my pc.
Hope thats a bit of help.
