Newbie wireless network questions.

[algae]

I have two desktops pcs and a notebook. I also have a cable modem. In order to set up a 802.11 G home network. I've decided on Linksys and I think I need the following:
Linksys wireless router WRT54G 4P
Linksys wireless PCI card
Linksys wireless PC card

My cable modem is located immediately beside my "main" desktop Pc.

Do I need a wireless access point in addition to the router listed above?
Do I only need a PCI card for the one pc that is not close to the cable modem and router? I'm hoping I can use a short cable for the pc that is close to the router and modem.

Sorry to ask such basic questions but I'm away for a couple of days and would like to buy this gear as soon as I get back!

Thanks much for any help.

No you do not need an Access Point.

For basic use Wireless Cable/DSL Router is a Combo of Router + Access Point.

However you should consider buying the SuperG made by D-Link or Netgear!

Why?

Look here: Link: 802.11a/b/g SOHO Routers & Access Points: Performance

You should consider USB Wireless to your Desktop!

Why?

Wireless is depending on signal propagation.

PCI Wireless Client Card ends up been stuck behind the computer's case, resultant in obstructed transmission and poor performance. USB is connected to the Port with 2-3' cable allowing the Antenna to be placed above the System for better Transmission.

However a PCI card is a good choice when a powerful external Antenna is needed for long distance. Many Wireless PCI cards come with a removable Antenna.

Another newbie question: Using any of the the 802.11g routers, is it true that if there's a client running 802.11b, the whole network drops down to 802.11b speeds?

Depends on the Hardware.

In some (look for reviews) it drops to 802.11b level.

In the more newer ones it drops, but it is still well above 802.11b
