I have a desktop linked to the telewest broadband service via the motorolla surfboard cable modem (512kbps down, 120k up) using the onboard fast ethernet PCI connector (which claims to be running at 100MBPS - I presume only as far as the modem). The modem came with a USB lead too, though only one can be used at a time. What should I look for to link a laptop wirelessly (mainly file swapping/ printer sharing) beside the laptop PCMCIA card - a router between the cable modem and the desktop (do these have firewalls built in?) or something which plugs into the desktop on PCI, ethernet or USB? Any good brands which are easy for network newbies to set up out of the box? I am using XP's firewall on the desktop but see that Zonealarm (I used to use with W98) is preferred.
