static IPs for linksys wrt54g wireless router.

You may need to switch to third-party firmware. See the wikis below.

The WRT54G cannot do this.

However, you can configure the computers to use static IP addresses. Just assign them addresses below the dynamically-assigned range. For instance, if your router is at 192.168.1.1 and assigns at and above 192.168.1.100, then just configure your computers (and other wireless devices) to use addresses like 192.168.1.51.

You don't. You do it at the client end, and optionally disable the DHCP server in the router.

(aside: some routers let you set the DHCP lease time to infinity. I've had three different routers that all handled this diffferently, with lease times from inf to 28 days, all of which had the effect of re-leasing the same IP each time to the same client.)

The standard firmware in the WRT54G, even V5, will do that; however, if the router power is recycled, the mac correspondence is lost. I have one computer that needs to have a fixed IP address as it is serves both NFS and subversion. As suggested earlier, it got

192.168.1.50, whereas the DHCP addresses start at 192.168.1.100.

"KraftDiner" hath wroth:

You can't do that with the stock Linksys WRT54G firmware. It lacks a feature called "static DHCP", "static leases", or "reserved DHCP".

If you switch to an alternative WRT54G firmware such as DD-WRT it has this feature. Unfortunately, the setup is a bit overly convoluted. See:

Others have suggested using static IP's on the workstations and not bothering with "static DHCP" in the router. That works, but has one problem. If the client is a laptop, and you want move around to other access points (i.e. work, skool, coffee shop, etc) that use DHCP assigned addresses, you'll need to change the configuration of your network connection. It's not particularly difficult to do, but it does get old after a while. There are programs such as Netswitcher to help, but it can all be avoided if you just use DHCP on the laptop clients and "static DHCP" in the router. I suggest using alternative firmware and specifically "DD-WRT v23 SP1 Final".

I have a recollection of getting round this by adding two connections, one with fixed IP and one with DHCP, and disabling whichever one was inappropriate. Much quicker than fooling with the DHCP settings.

How do (did) you create an additional connection for a single hardware device?

I just checked my WMP54GX settings and this link doesn't seem to apply to this pci adapter, (I can't get bridge connections to work with it either) but I remember doing it with my HP laptop that has a usb dongle. It's the "alternate configuration" part.
