I had tried to connect my internet using a 10/100 standard Ethernet card but my net connection was fluctuating. My Brother who is a network engineer told me to switch back to 10 mbps from 100 mbps full duplex and he prayed if that might work. Luckily enough it worked and solved my purpose of delivering uninterrupted net connection.
But i need to know why this happened. It would be very kind kind of you if you let me know the exact reason please!
