How I extend my wifi with a Vodafone router?

Sorry but the AEBS will not wirelessly extend the wireless network from most 3rd party wireless routers like the Vodafone router.

Since you cannot connect the Vodafone router to the AirPort Extreme using an ethernet cable and wireless is not compatible, your only option is to use a pair of ethernet powerline adapters to transmit the ethernet signal over the AC power lines in your home.

Then you can configure the AEBS as a "bridge" and set it up to create a wireless network with the exact same wireless network name, security and password as your main router. This will in effect, "extend" your wireless network. Post back if you need more details about this option.

Computers will automatically connect to the router with the strongest wireless signal, which normally would also be the closest device.

If you check your Vodafone router, you should see an available LAN <-> port on the back. Connect an ethernet cable from this port to the port on an ethernet powerline adapter and plug it into a nearby AC socket.

At the location of the AEBS, plug the other powerline adapter into a nearby AC socket and connect an ethernet cable from the adapter to the WAN (circle icon) port on the AEBS.

If you need more info on ethernet powerline adapters, you can enter this phrase in the search engine of your browser.

Push the reset button on the AEBS until you see the amber light blink more quickly and continue holding a few more seconds after this and release
