ZXDSL 531B Modem- Internet Sharing & Lan Sharing Prb

I have BSNL BroadBand connection with ZXDSL 531B Modem and and i have not changed any of its default settings,I just installed PPPoE Drivers and connected to Internet, it worked fine. But When i dO Wireless NETWORK search in my laptop,it recognized my ADSL ROUTER and gets connected,when i put the ip of my laptop in "Run" of my PC, i can see my laptop's share folders and transfer files etc,
But when i insert My Pc's IP in my laptop it gives error "Network Path not Found" And i can not use internet simultaneously,I either have to dial from my pc or from laptop each time to use internet.

Can someone guide me how to Configure modem in such a way that if i m connected to internet, then i can surf through both my PC and Laptop and I can transfer file or data both ways.

My PC is Connected to ADSL Router through Ethernet LAN wire
LapTop is connected Through WiFi


I tried certain tutorials given in different forums and blogs but it messed up whole thing so now i m running it at default settings.

Thanks

Networking is not a job for the novices. For sharing of files/folders it is definitely a problem if the OS are different, e,g,, between Vista and XP/Pro. Vistra used IPSec-6 whereas XP uses IPSec-4 protocol service.

Please have a look at this guide: http://www.indiabroadband.net/bsnl-b...etworking.html

Now i m able to surf both from pc and laptop simultaneously but can not access shared files of My PC from my laptop .

thats a problem.. you first need to make sure both can ping.. confirm the ip address of both the machines by typing ipconfig.. and output of both machines would help.. are you connecting both via LAN? or 1 LAN and 1 USB?

laptop through wifi and pc through lan wire
