So apologies up front as this may be a naive question but I would appreciate your support. I have a BT Whole Home WiFi system with 6 discs - the maximum permissible. This is connected via a BT Business Smart Hub (we run a business from home) but the WiFi on the BT Smart Hub is not switched on as is recommended when using the Whole Home disks. Each of the 6 disks has a device attached directly through the single Ethernet socket on the back of the disk. Soooooo - I need to extend the strength of the WiFi as I have some Arlo security cameras installed outside the house and the range of the WiFi is at its very limit making these cameras difficult to connect. I live in an old house with reasonably thick walls. My question is this and I hope you can help. Firstly which tp-link extender should I use and if successful will this extender give me access to all the devices connected to the Ethernet ports on the 6 BT Whole Home disks. (I just plucked AC500 out of the air as the 'model' number when asked as obviously I don't have a clue as to what I am doing!) Any help or advice would be greatly appreciated. Thank you.
