I have a Dell Inspiron with Windows 7 Home Premium.
There is a strange problem. I connect to the network through Wi-Fi. However as soon as I start downloading anything, the Wi-Fi on the laptop goes off. It does not start until I reboot. It functions normally if I do normal internet surfing. It just occurs when I download something. My guess is that it goes off when the data transfer rate is higher.
I have tried uninstalling and reinstalling the Wi-Fi network adapters, but that has not helped.
Since the problem goes away on rebooting, I am fairly certain this is a software issue. Any ideas on how to resolve this?
Update: I have observed that before the connection goes off, I have an IP address like 192.168.1.10 but once it goes off, the IP address changes to 192.168.137.1
