BT Hub 3 Wifi Extender Availability

Dumb question alert.

I want to get a single Wifi extender for by BT Hub 3, but having looked at the BT page, the EE shop, Amazon, eBay, Argos, and all the other online places I got pointed to, I can find a single new one for sale.

Amazon and eBay have a few secondhand/pre-owned, but I want to make sure that the extender works, so really want to get it 'new', with the option to return it.

Are these things no longer available? Is there a waiting list? Is there a secret store I need to go to?

Yeah, dumb question...I feel like I'm missing something...

Hi @mysterdee

Welcome to the community.

We can't guarantee that second hand extenders would work. The only extenders we sell can be found here on this Broadband Accessories page, but they're not compatible with the Smart Hub 3.

It may be worth speaking to our support team about Complete Wi-Fi Plus, which is compatible with your router.

Another option would be to buy a mesh system, the first unit of which plugs into one of the LAN sockets on the router, so is independent of what sort of hub it is and works just as well with the SH3 as with any other router. Then use the other unit(s) supplied with the mesh system as your extender(s).
This is also likely to perform better than a single extender that communicates with the router via DECT, which, as the Mod has stated, is not available to work with the SH3 anyway.

What you are looking for is "BT Complete WiFi Plus", if you feed that into your favourite search engine you should be able to find new units from at least one reputable seller that come with a money back guarentee!
