Sticky IP address on Linksys wrt54g

I've recently changed from a SMC Barricade 7004 to the above due to the
addition of a laptop with wireless. Unfortunately it doesn't seem to be
half the router the SMC is. My mine problem atm, is the constant changing
of IP address each time a computer is swich on or off, on the network. The
Linksys seems to give each computer a new IP address ie. 192.168.100.1 from
a pool of addresses every time a machine connects to the network.

Unfortunately this means a protected machine which is in the DMZ starts of
at 192.168.100.1 but when switched on again in the morning after work has
finished the night before becomes 192.168.100.2 leaving a totally
unprotected machine in the DMZ if it's been given the 100.1 address. The
SMC Barricade kept track of each computer and permantly assigned them the
same internal IP address. So Desktop-Games was 192.168.100.1, mobile
....100.2, mother# ...100.3 and playstation ...100.4(DMZ) and no matter which
machines were on or off they would ALWAYS have the same internal address
when connecting back up to the network.

Atm, everytime I switch a machine on, I have to double-click the network
icon near the clock, find what IP address the router has given it then
re-configure about 5 different programs ftp etc with the new address. On
the games machine I have a few open ports for Battlefields 1942 etc and I
have to enter the routers admin page and change the IP address under
Apps/Gaming every day.

I've never experienced anything like this before, the Linksys was double the
price of the Barricade albeit with wireless. Yet it doesn't seem to have
the ability to store the computer name/MAC and given internal IP address.
One of the reasons of an external box is so the computers don't need to be
permantly switched on. Can anyone think of any workarounds so all the
machines and games console can be permantly assigned their own 192.168
address rather than being given a new one on a first come first served basis
by the Linksys router?

Just hard-code the IP address in windows and select an address that is below
the assignable DHCP range. Thus, if your router is set to the default
192.168.1.1 and DHCP is configured to start at 192.168.1.100, then you can
manually configure windows with an IP address like 192.168.1.50 and place
that address in the DMZ.

This sounds like a bug.

When a client requests an IP address over DHCP, they send up the IP address
they used last and the DHCP server is supposed to honor that request when
possible.

Best solution is to dump DHCP and hard code the IPs on the machines that
matter (DMZ machine?) Just make sure you take that address out of the DHCP
pool.

If you need to be sure that certain machines gets certain IP addresses,
then don't rely on a simple DHCP server, but assign them static IP
addresses...

You can continue to use your SMC router. Use the Linksys WRT54G as an
access point only.

Leave everything connected as when you had no wireless, then connect the
uplink of one router to a regular port on the other. Don't use the WAN
port of the WRT54G. Disable DHCP on the WRT54G. Don't have the
WRT54G log onto the network.

Well I'm using Sveasofts bios so maybe it's a bug with that. I only had the
router a day before upgrading the bios so I'm not sure if it's common
behaviour with all Linksys models.
