You are approaching this all wrong.
ANYONE can access the BT FON landing page
You can connect with an ipod touch, iphone, blackberry, laptop. ANY wifi device.
You do not use a router of your own
FON is generally hosted by a cafe or by a homeowner
Basically, Mr bloggs signs upto BT broadband
A homehub arrives whiich broadcasts BT FON and BT openzone aswell as the BT broadband wireless signal.
Somebody is sat outside Mr Bloggs house with a Laptop. They click Wifi networks next to the clock and connect to BTFON. This= is similar to yourself connecting
This connects to Mr Blogg's BT HOMEHUB. The homehub then routes through to the landing page
IF Mr Bloggs turns his homehub off, the fon network no longer exists.
When you are abroad, say in Portugal. You will see a FON network in wifi next to the clock
This will connect in the same way as the homehub, no router needed. You just hope whoevers hosting the FON network doesn't unplug it!
Of course abroad, the FON network is not hosted by BT broadband, BUT when you connect to the FON network abroad, there is an option for BT.
SOME networks are hosted differently, but this is a general idea.
The fact you're not getting to the landing page suggests you're doing something wrong. Even if it wasn't compatible with BT, as you suggest, you'd still see a landing page of somesort. Unless you are not connecting to FON at all - which I'm sure you are.
EDIT: To connect to FON you only need the device you want to work online. It has to be wifi enabled
E.g. if you want your Laptop to work via FON, you only need your Laptop.
No router of your own, no special gadgets. Just the Laptop.
This is what makes fon so great, you just take your laptop in a bag. Turn it on, connect to the wifi network, login and away you go.
If this is a continuous problem I'd suggest a problem with your hardware or what you're doing. Not the networks.
