I just bought an AirPort Express N to extend the network broadcasted by my existing AirPort Extreme N.
I enabled "Allow this network to be extended" on the Extreme, and put the Express into "Extend a wireless network" mode and configured it as necessary. I must have done it right because now all my Macs see the original network (named PrivateWiFi-N) as before, but now receive the signal more powerfully, and the Express shows a green status light. So far so good...
However, on my brand new Windows 7 laptop (the only Windows machine I have), it only sees a network with SSID of PrivateWiFi-N 2, not the original (without the "2"). Attempting to connect to this 2 network results in failure. But by manually setting up a wireless network connection, and typing in the correct SSID, my Windows 7 laptop successfully connects to it.
So my question is, why is this happening? Is this normal? Or is there something I can do to correct this? I don't want to have to tell guests to manually setup a network connection on their PCs just to connect. And, despite the fact that it works, just knowing that it's like this bugs me.
Any help appreciated. Picture attached below.
