Is it possible for the router to assign the IP

Hello everyone, I would just like to say I'm a total noob when it comes to routers. I can handle seting it up and networking all my computers and that's about it.

My question is this, can the router be the one to assign IPs to the computers that is using it? The way I have it right now is that I would assign IPs to every computer by going to the properties and assigning it via Internet Protocol. This is fine and works great, but I have two notebooks/laptops that i use at home, school and work. By doing it the way mentioned above, of course I won't be able to use my wireless connection on my notebook anywhere else unless I go into the wireless properties and change the settings again. It's more of an annoyance than a real problem, but could I set it up to where my router is the one to assign IPs so that I wouldn't have to mess with the wireless properties on my notebooks when I use wireless at school and at work? The router and system info is as follows:

- Router: Linksys WRT54GX2
- Operating System: Windows XP SP2

Any help on this guys is greatly appreciated, thanks.
 
Enable DHCP on your router

Then set all your clients to "Obtain an IP address automatically", and "Obtain DNS server IP address automatically"
 
Thanks for the reply.

if I was to do that all my port forwarding settings won't work right since it depends on certain ports being open for certain apps for a certain ip. So if the IP on my notebook chances, the port for a certain app will no longer be open since the IP is different. Correct?
 
Cool, thanks for the help guys.

Where on the setup is this optino located, I've been playing with the settings for hours and have not found it. I appologize for my ignorance

Unfortunately it looks like that model doesnt' support setting reservations in DHCP. Any chance you can use UPnP to open the ports you need instead of static mappings?

I'm searching for UPnP options right now, where would I find that on the setup. Under what tab? Still looking.

If worse comes to wors, I'll probably just do the leasing method that some few had advised me to do, but I would rather do something that is more permanent.
 
I am not sure what are the limitations of the mini DD-WRT, but it might be that you can Flash your Router with DD-WRT Mini, it would be able to do IP reservation within the DHCP range (Static IP).

I.e. You can leave the TCP/IP Stack on Obtain Auto, and tune the Router to give the sae IP according to the coputer MAC.

For Laptop dual configuration, this can help, http://www.ezlan.net/faq#fewtcp-ip

This Router can do IP reservation as is, http://www.newegg.com/Product/Product.asp?Item=N82E16833162173
 
You could try to assign your wireless adapter static ip addresses that would satify all the networks you work in.

Where you type the static IP address for the adapter. Hit advanced. You can add more addresses, as well as more gateways.
