extend tp link router with base station

Will the base station work with my new router?

Yes and no.

Yes, if you establish a permanent wired Ethernet cable connection between the TP Link router and the AirPort Express and set up the Express to provide a WiFi network that uses the exact same wireless network name and password as the TP Link router.

No, if you are planning to have the Express connect to the TP Link router using only a WiFi connection and extend the network in that manner.......since Apple's wireless "extend" feature will only work with other Apple routers.

However, the AirPort Express should be able to "join" the TP Link router using a WiFi connection if you want to use the AirPort Express for AirPlay......but, the Express does not "extend" a network when it simply "joins" the network.

If you need a stronger WiFi signal in another area of the home, and you already have a TP Link router, then look for a TP Link extender to wirelessly extend the signal from the main router.

Yes, it is possible that another brand might work, but it is always better......and a lot simpler.....to use products from the same manufacturer that are designed to work well with each other.
