Hi all, I am having a Compaq Presario notebook, this is running with windows XP, other specification of my laptop are 3GB RAM, 320 GB hard drive, along with this NVIDIA GEForce graphical interface and compatible with Intel dual core processor. Along with these, I installed Comodo Firewall and AVGfree version. The machine is compatible with wireless connectivity. But there is a problem with the wifi connectivity. The network connection continuously dropping after log into the network service. And for this when I tried to check the network status inside of the network and sharing center under control panel it shows the network connection is no operational. I am not able to understand this problem, so I am here. I hope someone from here will surely help me to overcome from this problem.
