DHCP configuration

I have dhcp set up on the LAN0 interface of my wr44. It is set to give out 192.168.20.2 to 20.5 with a mask 255.255.255.0 and DNS and Gateway of 192.168.20.1.

When I hook a dhcp laptop up to it, it will either:
Sit there saying ‘acquiring network address’ and do nothing further or it will pick up an address of 0.0.0.0.

The firmware version is 5281.

The configuration has worked properly in the past. Is there any known issue with this relatively new firmware?

There are no known issues with DHCP. Have you tried upgrading to the latest firmware and trying again?

Have you run a trace from your PC? Are you seeing the DHCP requests go outbound? Have you also reduced the default response delay to 0?
