you would then be extending your network.....
choose the network you are trying to extend, put in the relevant security info and password, and update the express settings...
if you were doing a wired solution, you would choose create a wifi network, and then under the network tab, you would set it to bridge mode
You will not use be able to use the AE an Extender with a factory set BT Home Hub however will be able to join the existing network for remote printing and ITunes.
To create an effective network extension your router needs to handle a WDS - Wireless Distribution System and this is supported in all Apple some Linksys and Netgear routers however not so your BT Home Hub out of the box.
To get the BT Home Hub to do WDS is quite a geeky and a very technical performance involving Hacking Telnetting and command lines.
Even when WDS is supported mixed router systems can be flaky at best.
Frankly what may be the solution and you won't like it - is to Go into the settings of the BT Home Hub in your web browser and switch OFF the Wifi broadcast sling an Ethernet cable to your Apple router and set that up as your Wi-Fi transmitter, go out and buy another Apple AE plug that somewhere closer to the blind spot and set that up as the repeater.
This Will work but at a cost !
Alanoconner afraid it doesn't work as an genuine extender- its simply joining the existing network as described in line one above.
It will not achieve what the op wants and that's to beam into a blind spot sorry.
Thanks both for your fast responses. I am now a little confused.
Alan - your solution looks relatively simple, requiring the submission of the homehub security details, correct?
Keith - if I'm right, you're suggesting that I may need additonal hardware? Could be an expensive way to achieve what I'm trying to do. Is there a less complicated way to achieve the better signal I need?
Thanks to you both for your advice
Return your AE contact BT and get them to supply a compatible repeater.
Pretty sure they use/recommend a TP-Link device with Univeral rather than WDS relays such as this
Its not as pretty and compact as the Apple gear though is cheaper by a margin.
This advice is quite counter to my own preferences for Apple gear including networking equipment, however after the best part of 11 years of setting up Wifi and home networking its a pain to get right.
