Ralph, I really appreciated the help you gave me in setting up my airport express a couple of months ago. I however have ran into a problem. I needed to change my wifi password, and when I did it really messed thing up. I couldn't connect to the airport extreme or the express. Every time I tried to access te settings on both I would get an error saying to the effect that the airport utility could not detect the settings on both.
I reset my extreme and on the wireless tab I did the "create a wireless network", along with "allow this network to be extended". I did the wpa/wpa2 personal security setting as well. Everything else was set to "automatic". And that fixed my problem with the airport extreme. I was able to have access to my wifi network and Internet capability once again.
I reset the express and on the wireless tab I did the "extend a network" and entered in the name if the network I wanted to extend, along with the password. And I did the wpa/wpa2 personal security setting as well.
I then performed a power down of the modem, the extreme, the express, and the computer. I then powered them up in this order, allowing time for each one to stabilize, the modem first, then the extreme, the express, and finally the computer.
But that is where I run into my problem. I now don't have Internet or wifi connection. When I go to the airport utility I cannot get into the settings on either the extreme or the express. But as soon as I unplug the power to the express everything works. It's almost like when the express is powered its canceling out the extreme.
Do you have any idea as to what my problem is and how I can fix it? Thank you in advance for your time and assistance.
