I have an ISP (Beam telecom, if it's relevant) that provides only a LAN cable connection using which whichever site you open you are redirected to its portal page where you are required to login. After this you can access internet as normal.
The problem that I am facing is when I am trying to setup my ADSL router to use it as a wifi router so that multiple devices can connect to the internet.
I have connected the ISP's RJ-45 cable into one of my ADSL router's LAN port and I am able to connect to the internet through the same process through the wifi network.
The problem is that when one of the device has successfully authenticated with the portal(that device gets an IP) if I try to use that WiFi from any other device, I am again greeted with the portal page. After authenticating I get access to the Internet in this device, But the previous device loses Internet access and that device is greeted with the portal login page.
So in effect only one device is able to connect to the Internet at a given time.
I have seen few forum post saying if I use a normal WiFi router which has a WAN port and not the ADSL that I currently have. Would resolve the issue. But I am in doubt if this would really fetch me anything. As I won't like to spend money in another router if it goes to vain. So any ideas if a non-ADSL router would resolve this issue. Or if I can change my existing router's setting so that I can connect mor than one devices.
My ADSL router is: Linksys Wireless-G ADSL Home Gateway Model:WAG200G.
And would a flash of dd-wrt custom firmware on my device would fetch me some new options that would allow me to make use of my ADSL to work as a normal wifi router?
