As I read discussions like http://www.indiabroadband.net/mtnl-broadband/40011-configuring-utstarcom-wa3002g4-wifi-modem.html the feeling I get is this device is unsuitable for you and your needs.
Following are my components at hand.
1. My super awesome desktop with the regular gigabit, on board lan card (on Win7).
2. A laptop, with wireless connectivity (again on Win7).
3. A modem, UTStarcom WA3002G4 with an internet connection from BSNL.
The modem is a wireless modem.
Now for my question.
I want to be able to connect the laptop and the desktop in a single LAN connection, so that
i)I may play NFS Most Wanted on both the laptop and desktop through the LAN play.
ii) I may share files and folders, fast and without any hassles.
*though mostly only the first
So, this being my completely descriptive question, I request help from all quarters. Any kind would be greatly, exceptionally, and exceedingly appreciated (nothing more I can do sitting in front of a comp ).
Request you to give detailed steps, a noob's request.
