Not sure what you mean.
Do you mean you want to connect to BTWifi or your own home network via wireless.
If you want to connect to your own wireless network you need to set your devices to scan for wireless networks and look for your own BT Homehub's SSid (name) . It will look something like BTHomehub5-xxxx.and can be found on the label on the Homehub. Once you have found that you click on it and enter the wireless passkey that you will find on the Homehub label.
If it is the BTWifi network that you want to connect to you need to scan until you find the BTWifi with Fon network. You then click on it and connect. Once connected you need to open a web browser and that should then open the BTWifi-Fon "landing page". You then enter your BTID and Password and this will then log you in.
No. I meant the most complicated option you can imagine.
I have Internet on PC from "usb tethering" Its a normal network adapter.
I want to share my PC's internet connection TO BTHH5 i.e. from PC's LAN card, to WAN connection at BTHH5.
How would I configure that?
Sorry but you have lost me.
What are you tethering from?
Do you have BT Broadband?
Do you have a Homehub 5?
Does your PC have a network card, either wireless or Ethernet?
If the answer to the above is yes,you just need to plug an Ethernet cable into the Homehub and then into the Ethernet port on your PC.
If it is wireless you do as I explained in previous post.
If you mean you want to share a Windows 7 wireless connection you can download a program called Virtual Router which will turn your Windows 7 into a hot spot.
Sorry I have no idea if that will work or is even possible.
Have a look at this it might help
