Question: any chance that wireless access point, wrt54g type with ddwrt, could cause a cisco router to go buggy and drop dhcp requests and other network issues?

looking for some advice as the units are within a foot of each other and this is turning into a blame game between two companies that installed the equipment.
thanks

Answer: 
Are these hooked into the same network in anyway (wrt54g goes into the same switch as the router, or the router itself)? If that is the case, maybe you have some **IP conflicts**. If they are both in the same broadcast domain, and are both running dhcp, then when clients request IP addresses you don't know which will answer. 

Since the dhcp servers won't know who is given what, you might end up with duplicate IPs.

Physically, the would not interfere with each other.
Logically, if configs are conflicting, sure. Physically located next to each other, I doubt it, unless the Linksys has some hardware malfunctioning in it. Is it possible to just shut off the Linksys temporarily?
