The radio has probably failed. I have had two 54Gs and after several years of service their radios wear out. Router function is usually independent of radios so you can continue to use the 54G as a router.
Time to replace the router and or buy an AP to connect to your 54G. To maximize radio life be sure your router or AP is in an area where it won't over heat. I keep my router and modem plugged into a small UPS so my internet stays on when the power goes out. The UPS isolates the router from power fluctuations which hopefully increases its life.
With your new router, if the software permits, set up your router to turn off the radio automatically at times of day when you won't be needing them. Also adjust the radio's power setting to be no more than you actually need for reliable service.
