internet and router problems

Specs: Windows XP
Have a wl520gc router which has been working well with a desktop computer and 2 laptops. Today it decided to stop. Rang optus and had two different people try by resetting modem which was successful for the laptops but not the desktop. The modem is a motorola SB5101- supplied by optus. When we try to find the IP address for the desktop we get nothing when the appropriate commands are run. I have turned off the computers, router and modem in this order and then turned on the modem, router and finally the computer. Still no luck. I am hoping someone can suggest a solution as the desktop is my disabled daughter's computer and she is extremely distressed, the neighbours can attest to this. I do not want her on my laptop as it is my work computer. Sorry to be a pain but any solution will need to be step by step for me.

You have not yet narrowed the problem to one particular device. There are two or three possibilities here. Since the laptops can get internet the modem is obviously OK. Are the laptops connected by ethernet cable or wireless? Presume they are wireless. That leaves you with the wired PC unable to connect for some reason.

You need to experiment to determine whether the problem is in the router, the cable or the PC. Here's how. Power down all the devices. Connect one of the laptops to the router using the PC,s ethernet cable. Power up the modem>Router>wired laptop.

Do you get internet? If YES the problem is in the PC. If NO the problem is in router or cable. Do you have a spare LAN cable to try with? That will help eliminate faulty cable as the problem. You must power cycle the router each time you make a change. I take it you have not used the RESET button on the router?
That may be what's needed but you would then need to re-configure all the WAN,DHCP & WLAN settings. If the ethernet port part of the router has failed you will have difficulty with the re-configuration since router admin management is usually done from a wired PC.

Thanks gone fishing. I realised late last night that I did not say that I had isolated it to the PC and it is wired. Thanks for your help but tried everything again today and still no luck so have called in a technician as it is getting beyond my abilities to even follow instructions. thanks again for the suggestions
