limited or no connectivity

Disclaimer : Computer Related

I dont know how many of you have had this problem? Yesterday i had this problem in home laptop. I could'nt connect to my wireless router. It kept giving me this error.At first i thought it could be the problem with the router. What happens at times is, as we dont turn off our router for days together, it would require a simple restart. I tried that but in vein.

Then i saw that, this message (limited or no connectivity) i was recieving when my system was trying populate it ipaddress, i mean thru DHCP. So now i thought DHCP server in the router was not working properly.

So i assigned a static Ip in the subnet as that of my router and DNS as my router and tried again, this time it was wierd, i was able to ping my router but nothing beyond it. So this eliminated the problem with my wireless card.

I tried repairing the network connection, tried restarting the laptop but all measures failed. Was wondering if i had re install my OS, that would be tedious.

So when i googled from my friends system, i found that, the culprit could be some spyware. My firewall program (ZONE ALARM) had run a scheduled check previous night and had found handfull of spywares, and some sites said, while removing the spywares some of them corrupt the TCP/IP stack.

So, that could be a posibility and luckily i found this tool

I must say that this is a must have tool! work fine and if you are worried that, its altering ur registry you can also, take a snap shot of ur registry with this, in case u want to revert back.

I have come across this, whenever my system fails to obtain an IP address from the DHCP server. There is an option to disable this notification. So I normally solve this by assigning a static IP to my system!
