Setting up WLAN prior to NTL Braodband connection install

Hi,

I will be getting NTL Broadband addded to my existint TV package next
week. I have decided to use the opportunity to set up a WLAN with
router to avoid the cables around the house and share the internet
connection.

All the kit has been ordered and will be here for the weekend - I've
gone for the Linksys WAP/router, USB adapter for the PCs and PCMCIA
card for laptop.

So I have the ideal opportunity to get the LAN setup before Broadband
connection is there. What I am after is some advice on how to set this
up in preparation for the install, so as to minimise any hiccups on
the day.

I assume that I set up the LAN and get that working; which i expect to
be straightforward - it's the configuring the router that I am nervous
about (having not touched this side of networking before).

Any help will be appreciated.

Cheers

Paul
