Are you experiencing an error message " Limited or No connectivity "

Both ways go for the following steps to solve the problem.
Start > Control Panel, look for " Network Connections " and Double click it.
You will be able to see Local Area Connection (It is possible that there is more than one icon, in that case choose the one with Limited or no connectivity )
Right click & Select “ properties “
Select Internet Protocol [TCP/ IP] & click " Properties "
Choose " Use the the following IP address " and " Use the following DNS server addresses " and insert the values as
IP Address : 192.168.1.2 (If you wish a static IP, use 192.168.1.25)
Subnet mask : 255.255.255.0
Default gateway : 192.168.1.1
Preferred DNS server : 208.67.222.222

Click OK.
Click OK in the Local Area Connection Properties
Now you will find the error message has vanished.
If not please restart you system and modem to find the connection to be ok.
Please note that the values are added keeping mind BSNL server. The procedure is same for all ISP. If yours is not a BSNL connection, take down the current values and then try. You can always revert to original values by repeating the procedure with same values .
