The modem is Huaweri MT 882. There are five lights: the power light which is always on, the link light which shows when the modem has connected, the ACT light which blinks when there is data transfer, the Lan light which is how I connect to the modem and which is always on but orange colour, and the USB light which also blinks during data transfer even though I have not connected through USB.I've been facing an unstable connection since yesterday, where the connection drops every two minutes. Today I'd connected but there was no data transfer so I thought that I'd disconnect and reconnect, but even after I disconnected, I found that the ACT and USB lights were still blinking. The USB light stopped blinking after a few seconds but the ACT light continued as if I was still using the net.Can this happen because of malware? Is it possible for data transfer to continue after I've manually disconnected from within Windows?
