Hi buddhu

Welcome to India Broadband Forum

1.) Go to RUN Command and type ncpa.cpl
then right click on Local Area Connection and left click on Properties
Under Properties double click on Internet Protocol TCP/IP and see if it is on
Obtain an IP automatically or on static IP

2.) How are you cleaning DNS Cache/ what all you tried

3.) Please provide details of your modem/router. Status of DSL/ADSL/Link Light and are you facing disconnection on wireless connection or on wired connection
please check if DSL light goes off or flashing at disconnection.

Karamjeet

for your DNS cache problem:

Run->Services.msc and make sure DNS Client Service is running and set to Automatic.

buddhu

Thank you karamjeet for your suggestion....
I've made DNS Client service running as automatic from 'disabled' set up...
....BUT UNFORTUNATELY THAT DOES NOT SOLVE MY PROBLEM...
??????????

PROBLEM
Question :
what is DNS cache and why we should clean it?

The DNS cache contains a record of all your system's DNS requests.
It would look something like this (if it were a true text file)..

123.222.10.117 =
airline tickets cell phone deals at whatever.com
123.16.10.118 = Something.

..and so on.

So, if in future your system wants to know
what the IP address of airline tickets cell phone deals at whatever.com is,
it will look in the cache rather than requesting
a name resolve from a DN server on the Net (for speed). However, if your DNS cache becomes corrupt
or if one, or more, of the IP addresses
have changed.. then you might be asked to clean it.

QUESTION ;
how often we must clear the cache?

Very rarely, if ever at all.
You would normally only do this if you have
been asked to by a support person
or if you had suddenly lost your ability
to access some or all of the Internet
without any apparent reason.
=====================================
Suggestions;
IN SAFE MODE
start/ run/ cmd/ ipconfig/ flushdns

or arp -a In safe Mode.

Try

Run->cmd
netsh int ip reset c:\resetlog.txt
netsh winsock reset all
regsvr32 ole32.dll
regsvr32 netshell.dll

then restart PC.

you may have to configure the LAN IP Address again because above commands reset the TCP/IP to clean state.

Precaution :[
Before attempting to change REGISTRY entries
(A)it is preferable/advisable to create a System Restore Point.
or
(B) back up existing Registry entries. ( working condition ).
Para two ;
specify what is the problem about DNS cache , you face,
when surfing the Internet.
