Radius client router

[sibyseb]

Hi
I live in a residential complex attached to an institution . I have activated my internet account provided by them. There is an ethernet port in the house to which I can connect a PC directly. It automatically gets an ip address etc, but not internet connectivity yet. If I open any browser, the first page coming up is a log in page where I need to put my username and password. (similar to the wifi hotspot authentication seen in the airports etc.) After that internet connectivity is established. I think they use radius authentication system.
My question is can I configure a router as a radius client so that it wil automatically authenticate and I can connect both my PCs to the router?
Thanks

ADSL is simply a radius sever. I expect that a standard router may be able to do it but I could be wrong. This should be in the network section.

Thanks for the reply. But I can't use an adsl modem router as my broadband is provided off ethernet port and not phone line. I could not find any way to authenticate using my router which is a standard dhcp client. It does get ip address and dns servers but still can't access internet.
There was another interesting thing I did. I cloned my pc's mac address to the router. I then authenticated my internet using the pc and then disconnected the ethernet which was then connected to the router. I did get connectivity through router for about 12 hours!
I wonder there may be routers which has got radius authentication in its dhcp client part where I can put my username and password.

why not get a RJ45 to RJ11 converter?

I think you are barking up the wrong tree TBH.
If its a web page used for authentication, it could be any protocol used for authentication.
RADIUS is not used between the device to be authenticated and the Authenticating device. It is used between the authentication device and its upstream authentication server.

You are probably thinking of PPP or something like that.

thats a very good point.

Have you ask whoever gave you your internet account about hooking up a router, or asked anyone else in the residential complex?

Looking at my router (it's connected to a cable modem via Ethernet) it's got lots of connection types, and a few you can enter usernames and passwords, these are PPPoE and PPTP (Telstra Big Pond but I guess that's for Oz land) if you've got them you could try them. But i've no idea what radius is, so might be a waste of time.

How about running a linux firewall, e.g. Embcop (embedded IPCop), on a WRAP/ALIX or similar motherboard. If you know anything about linux, it should be a simple matter to automate the authentication page and also to monitor it so it reconnects automatically

Thanks for the replies.
I think badass made a valid point. I don't need any authentication to get LAN connectivity. I can even see other computers on the network. It is only when I try to access the internet, the browser comes up with the authentication. Once that is done, all applications in the PC gets internet connectivity. I don't need to authenticate again for the same computer for long time even if it is shut down for a brief period. That made me think that the authentication is for a specific network interface mac id, which made me to clone my PC's mac id to the router. It worked. Once I authenticate using the PC, I swap the ethernet cable to the router and it works.

The suggestion from countzerouk is probably a solution, but may be a bit more complex and expensive (I haven't searched much about that). I wish a cheap router could do that!
