In my office network I have observed that turning on my laptop brings the internet speed over the network down by a huge amount. The moment my laptop is turned off (or is brought out of the network) the internet starts working normally.
And when I am in my home network, I find that entire bandwidth of 15GB gets used up in 15-20 days even when I don't do much downloads or any activity worth 15GB.
The above two things make me suspect that something is wrong with my computer. I have also tried to scan my computer with antivirus but it didn't detect any threat. I would like to know how do I narrow down to the cause of the problem. Kindly suggest.
My Laptop is ACER Aspire TimelineX 4820TG - Windows 7 32-bit. Kindly let me know if I should be providing any more details.
