Should me computer, router and router range expander all have the same IP Address?

Asked by Quandry (45points) April 9th, 2010

I just upgraded my wireless router to an N class, and I still have a cold spot in my house so I added a range expander. All of these devices appear to have different IP addresses. Would this cause communication or connectivity or performance problems?

They may not have the same IP address. IP addresses must be unique.

Isn’t the router the one that assigns all the (internal) IP addresses to everything?

It’s the DHCP server, which the router may be configured to become.

There should be no duplication of IP addresses in your active network. However, each device must be in the same IP address range, otherwise those that are duplicate are bound to have connectivity issues. For example: Your router has an IP of therefore, all other devices must have the IP format of 192.168.1.# (# being unique number in the range of 2 to 254)
