Change router(s)' default IP ?

[3l3ctr1c]

Hello,I've a networking setup in my office for about 35 computers through a switch. I've 3 airtel connections connected to the switch. What I desire is using 3 differnent IPs for the three routers (other than 192.168.1.1). I know I could top the bandwidth of one connection and use it as one but my current circumstances prevent me from doing so. I went and changed the router's IPs in the LAN tab from main.html and rebooted them, but for some reason they wont work. When I see the status I get an "authentication failure" status for the PPPoE or "unkown". What am I missing here ?I want three routers with differnent IPs so that I have three differnent gateways and can then divide the gateways to the computers in a way I desire. Kindly elucidate.Thanks for your inputs.

members/3l3ctr1c/ Show your set up required like this: ( also modem details )1...... Airtel A:modem/router 1====>>> hub or switch==>>lan1 say12computers............Airtel B.................2 same as above ............Airtel C...... beetel 220 Bx same as above and Apache web server 2.Or all in same LAN and can connect to any airtel BB connection.and/ or can access any computer in the LAn for file sharing printer etc.Para two : Connecting two or more ISP's to one computer or LAN net work will not Increase ( add up) the download speed. If one fails another connection will take over. Expensive set up required.I have tried with three different ISPs /different speeds( two BB modems ,+ one dial up modem ) in Same computer/LaptopThe higher speed connection takes over. Switched it off connection continues at a lower speed.
