I have been playing with openwrt version of coova, and try to configure it to use Coova radius. But I am confused.

So I ask :-

1. If I want to do session accounting, then I must use
WPA radius for encryption setting ? This is what I
read somewhere in the documentation ...

2. When I use HostSpot Type 'ChilliSpot UAM'
and Auto configuration 'Web URL', I got it working.
But I can't have it to present a username/password
login.

3. When I use HostSpot Type 'ChilliSpot UAM'
and Auto configuration 'Radius', it is not working.
Internet access failed. Why ?

4. Anyway what is the difference between auto configuration type 'Web URL' and 'Radius' ?

Appreciate your replies.

Sorry I am offended you with newbies questions.

Regards.
