prashantv,

Try these tweaks....

Start, control panel, device manager. Click on Network and then right click on your network adapter, left click properties, power management. Uncheck the box, allow computer to turn off this device to save power.

Go to the power options, and changed the Wireless Adapter Setting, from Maximum Power Setting to Maximum Performance.

Thanks Rick. I tried it and checked. Was slightly better than before but it still continues.

I was connected for longer than before but it got disconnected after a while. On reconecting, the problem still continues.

prashantv, Can you run Network Interface and post the information back here. Rick

i can't find it Rick. Can you please tell me what exactly to look for

prashantv,

Network Interface tells me the type of security you're using in your wireless router, what channel and what wireless adapter you're using/

You can provide the make and model of your wireless router and the type of security. What channel?

What wireless adapter is installed on your system?

Rick, Please find the details: router: H3C (H3C WA2612 - AGN) Wireless: Dell Wireless 1704 802.11b/g/n (2.4GHz) security - wpa2-personal, encryption- AES

prashantv,

Try this first...

Start, control panel, device manager, network adapter, double click on Dell Wireless 1704 WLAN Half Mini-Card, advanced. Look for Antenna Diversity. Change the Antenna Diversity from Auto to Aux

Go to start > device manager > advanced > bandwidth capability > change to 20/40mhz

If that does not help, then try changing the channel in the router to channel 1, 6 or 11. I use channel 11.

Last resort would be to change the type of security to the Recommended Wireless Router Settings to see if your connection is stable.
