|Something is definitely not right.|
The first thing you need to do once your PC is connected to the extender is to check your TCP/IP settings. To do so, open a command prompt window (ie: Start >> Run >> type cmd and hit Enter) and perform the following command:
If your IP is not in the same subnet (192.168.0.XXX - where XXX is any number between 1 and 254 excluding the IP of the extender .50) then you will need to manually set it to one. You do want to use the same subnet mask in both cases (255.255.255.0). The DNS setting won't matter so don't worry about it.
Once both your PC's interface and the extender are in the same subnet, they will be able to communicate and you'll be able to get into the management interface using your web browser and then be able to change the extender to the correct TCP/IP settings.
Example TCP/IP settings:
It matters not how straight the gate,
How charged with punishments the scroll,
I am the master of my fate;
I am the captain of my soul.
