About six months ago, I started having a DHCP issue with this router. I have numerous computers/toys connected to the router including an Apple TV. When I bought the Apple TV, I connected it wirelessly using DHCP. One day later, I was unable to get internet on any computers, including the Apple TV. The problem was narrowed down to the DHCP server issuing the "169.XXX" ip address. I checked everything that was connected to the router and they were pulling the same address. I thought, no big deal, I'll just reset the router and it would clear out any problems it had. Nope, the problem still persists to this day. I ended up having to use static IP addressing, but was wondering why this literally crept up over night. I've upgraded to the latest firmware, did a complete reset, and rebooted numerous times, but DHCP will not work correctly. I've purchased several new laptops since then and they instantly pull the 169 IP address, so I'm ruling out the fact that it may be my older equipment. Any ideas on what may be causing this issue and what I should probably try?

Thanks,
Dez
