I have my router (WRT54GL with DD-WRT v23) configured for DHCP. For some reason today it stopped working let me explain what happened. My laptop plugs into the wired portion of the router and I unplugged it today to go do some work. After leaving my house and going elsewhere I turned the wireless adapter on and had the internet. When I returned to my home and plugged back into the wired connection I couldn't get an IP from the router. I tried disabling the wireless card (to avoid conflicts between the two) and releasing and renewing the address on the laptop. The only thing that fixed the problem was rebooting the router. I don't want to have to reboot the router every time I unplug and plug my laptop back in. What's the deal??!?!?!?
