Wireless extender will not give internet access

is this ADSL telephone router ? dont see why you cannot setup your own router - you just wont get any support or help if it goes wrong - in which go back to the sky router when check that does not work and then call support

I have an EW-7209AP

You may already have done some of this:

connect PC and Edimax with a cable.
Make sure that the WiFi network router is on.

1. Go to network connections and in the TCP/IP section set the fixed IP of 192.168.2.10 and the subnet mask of 255.255.255.0. Leave the default gateway and DNS blank. Close this window with OK.

2. Visit the access point setup window by typing the address 192.168.2.1 into the browser .

3. Enter the user name/password: admin / 1234

4. Click on Basic Setting in the list on the left of the screen and select 'Station Infrastructure' from the mode drop down list (in the centre of the screen).

5. Click on 'Clone MAC'

6. Click on 'Select site survey'. Then click on 'Refresh'. A list of accessible WiFi sources should appear. Select yours and click on 'Connect'.

7. Click on Security in the LH list.

8. Choose the encryption type to the same as your WiFi router

9. Enter the WiFi network key in the space at the bottom.

10. Go back to the network connections in Windows, choose TCP/IP properties and set it back to 'Obtain IP address automatically'.

11. Make sure you power off and restart the Edimax and Windows network connection to reset the connection and everything should work. - this was a step i missed and did not get working
