Let's double-check your roaming network configuration just to be sure nothing was missed.
Roaming Network Setup
- Ref: See page 42 of the Apple AirPort Networks guide.
- Setup the AirPort connected to the Internet to "Share a public IP address." Internet > Internet Connection > Connection Sharing: Share a public IP address
- Setup the remaining AirPorts, as bridges. Internet > Internet Connection > Connection Sharing: Off (Bridge Mode) For each AEBSn in the roaming network:
- For each base station:
- Connect to the same subnet of the Ethernet network.
- Provide a unique Base Station Name.
- The Network Name (SSID) should be identical.
- If using security, use the same security type (WEP, WPA, etc.) and password. Note: It is highly recommended that you use WPA2 Personal for best bandwidth performance.
- Make sure that the channel is set at least three channels apart from the next base station to prevent Wi-Fi interference.
I am not real technical so bear with me...
First, how do I check to make sure I am connecting to the same subnet? Secondly, where can I set the channels on the AEBS's?
Also, this is weird, but may help troubleshoot...
Both stations have green lights. When I unplug the Express (because it causes devices to lose connectivity), my WIN 7 PC loses wireless connection to the EXTREME. I determined that the Network Key somehow gets changed to a like 50 character password. When I change it back, my PC re-connects to the EXTREME fine.
First, how do I check to make sure I am connecting to the same subnet?
If both routers are connected to each other by Ethernet, then they are on the same subnet.
Secondly, where can I set the channels on the AEBS's?
You can set the channels using the AirPort Utility in Manual Setup mode: AirPort Utility > Select the AEBSn > Manual Setup > AirPort > Wireless tab > Radio Channel Selection
