Sharing Intenet Connection over LAN

Specs: Windows XP
Hi All,

I have a scenario in which i am already using BSNL Broadband connection which is connected through a Wireless Modem having 4-5 Ethernet ports. There are other 4 computers connected to the modem via ethernet ports & hence can access the internet.

Since, the BSNL connection is getting frequently disconnected every now and then because of their poor service, i have connected a USB Reliance Netconnect (Broadband @ 3.1 Mbps) modem in the USB port and have installed the Dial-up application & drivers on 1 system. Now, i can only access internet in the computer in which i have inserted the Reliance USB modem.

My question is:
1. How do i configure my Reliance Broadband connection so that intenet can be available on LAN by default to all the computers?

2. Can both the internet connections be active at the same time on this LAN?

3. If i want to use only Reliance Broadband then, how do i disable this BSNL Broadband as i am using that modem as a LAN?

Thanks & Regards,

The answer to question one is you can, but its a bit complicated and with four computers I wouldn't reccomend it. It involves installing Internet Connection Sharing and installing and configuring it on all computers.

Question two is no you can't. Windows will only use one Internet connection at a time usualy the first one it finds, and ignore the other.

Hoever the last bit has got me a bit confused. You cannot normaly have two DSL services on the same telephone line which is what you seem to be implying unless you have two seperate telephone lines.

You can use the Reliance Broadband only by reconfiguring the Wireless/Router/Modem that is using BSNL to use Reliance instead. This is a relative simple matter and just means replacing the username and password configured in the Modem. The manual will tell you out to do it.

If Reliance have a half decent help desk they should be able to tell you how to do it but then they might not if it wasn't them that supplied the euipment.

Keep the BSNL Modem/ Wireless Router but switch off the WiFi side.

Purchase a twin WAN Wireless Router like:

On the PC/Laptop with the Reliance Connection setup ICS on the Ethernet Port, I am presuming this also has Wireless capabilities!, and cable join to new router.

Therefore the WiFi connection on all PC/Laptop will be thru new Router..................

BSNL Modem/Router + ICS PC/Laptop
New Router
Wireless to PC/Laptops

ALternatively replace the Modem/Router and the proposed new router with something like this:
