Lose TCP/IP connection every day when lease expires

I have a very early WRT55AG router on my network, which only allows me to lease a TCP/IP addresses for 1 day maximum. My network is currently configured using 192.168.1.x. Every day, when the TCP/IP lease expires that machine does not automatically renew its lease, and thus loses internet connectivity. The IP address changes to the Auto Addressing schema 169.... When I try to manually release and renew the IP address, I get an error that the machine is unable to communicate. I've tried rebooting machines, and it did not help. The only way I have found to solve the problem is to reboot the router, which in turn means I have problems on all the other machines and have to release and renew them as well.
I'm thinking that the WRT55AG is pooched (bad) and needs to be replaced.
Does anyone have any ideas on other things to try before I replace the router?
