I’m on 100 mbps which I guess is not the fastest VM provide.
the speed of the connection has nothing to do with the quality of the wifi.. and looking at the extender you have, there's no reason it won't work with the hub.. but the hub is a basic device and the wifi it provides is, based on these forums at least, pretty unreliable.. as I doubt you're eligible for a free wifi pod from VM, you can either try to work out why your current BT extender isn't working with your hub or you can look into alternatives.. an entry-level mesh system should provide you with reliable wifi around your property (perhaps extending to the garden) and will probably cost in the region of £130.
Welcome back to the community page, thank you for posting on here.
I am sorry that your internet is not reaching you gardens.
I have managed to locate your account using your forums details, I can see that the WiFi is running slower than normal, this is due to some devices being too close to the Hub, please can you make sure you move any devices away from the Hub that could be causing this?
