Fails to connect to network on boot, have to reset network adapter

I have a wireless network at my home which is already running two windows xp desktops without any problem. Yesterday I bought a new Dell laptop which came pre-installed with Windows Vista Business Edition. There is something wrong with this laptop because no matter on Wireless or with Ethernet cable, it looses the connection to my router in few minutes and thereafter it wont connect to my router. Am sure there is no problem with my router because I use my smartphone wirelessly on the same and two computers are as well running with it.

When I ran ipconfig on this laptop, it shows:
Ethernet adapter Local Area Connection:
Connection-specific DNS Suffix . :
Default Gateway . . . . . . . . . :

Every time I need to reset my network adapter by going to Network Adapter Diagnose and Repair to make it connect again to internet. It is very annoying. Is there any permanent fix for the same? BTW what could be wrong with this brand new laptop?

Hello Gopieee, you must know that there still many routers which are yet not compatible with Vista operating systems. I guess the same has happened in your case. Though it is working fine with XP I guess it is not compatible with vista. What is the make/model of your router? So just check if there is new drive for the NIC and a new firmware for the router? If its there, update them all.

Just go through these steps and see if it fixes the problem:

• Click Start, Programs\Accessories and right click on Command Prompt, select "Run as Administrator" to open a command prompt.
• Reset WINSOCK entries to installation defaults: netsh winsock reset catalog
• Reset TCP/IP stack to installation defaults. netsh int ip reset reset.log
• Reboot the machine.

I appreciate your helps guys. Today I was doing ipconfig /renew on my vista laptop and it resulted in the following.

C:\Windows\system32>ipconfig /renew

Hello Rowan,

I have the same problem as you do with my new lenovo running vista x64 business. The solution I use now is the same, restarting the intel wifi link form the manage netwoork connections pannel. Did you find any solution that really makes sense?

Thanks in advance,
