Poor internet access - packet loss when pinging router and adsl modem

I am setting up a wireless network at home for the first time and am
having a few problems with Internet access such as slow and partially
loading pages and lots of timeouts.

I've got a Linksys WRT54G wireless router (model number 1.1, firmware
v1.42.2) this is wirelessly connected to a desktop PC via a Linksys
PCI card WMP54G and a Laptop using a Linksys PCMCIA card WPC54G. I've
got a Netgear DM602 ADSL modem which is provided preconfigured by my
company and is connected directly into the wireless router via an
ethernet cable. Both PCs are running Windows XP.

The wireless network strength is very good (I've got everything in the
same room for testing), and communicating between PCs seems fine,
pinging between the two PCs gives 0% packet loss. However, when I ping
the wireless router I lose around 40% of packets and when I ping the
ADSL router I lose around 55% of packets. This kind of rate of packet
loss is also there when I try and ping websites.

I've turned off any software or router firewalls, and while I set up
am temporarily running without any wireless encryption.

I don't understand why I'm seeing this kind of packet loss when
accessing the router/adsl?

1) You have the Wireless Zero Configuration service enabled? It could be
causing a lot of problems.

2) Did you install and configure the driver for the card using the Device
Manager. It seems that things work a lot better when that is done, along
with not using the card's utility to even show signal strength. The
signal strength will be shown when selecting *Show connection* in the NIC
Properties. You can put the mouse on the icon and it will show the
strength.

3) You got the Bridge icon there when at the LAN Connection screen? I
deleted it and I don't use the Network Wizard to do anything.

Those were 3 things I did to make the wireless on the XP O/S become
stable.
