I've got two modems:
D-Link DSL-2730U Wireless N 150 ADSL2 4-Port Router - D-Link: Flipkart.com
and
TP-LINK TD-W8951ND 150Mbps Wireless N ADSL2 Modem Router - TP-LINK: Flipkart.com
The Dlink one is connected with the phone line and is used for using the Internet; the TPLink one is lying idle.
Now I have a laptop and a desktop, and the desktop is lying in another room and does not have any internet connection. To use the Internet on that one, I'd have to buy a wireless USB adapter. If I connect the TPLink modem to the desktop by wire, will it catch the waves from the DLink one connected to the phone line, and that way can I use the Internet on the desktop? What I am saying is, to use the TPLink modem as a wireless USB adapter.
