A friend recently asked me (as if he had exhausted all his efforts to find out otherwise) that his internet at times acts very slow and especially at certain times in the evening and on weekends… my first question for him was does he have any computer in the network downloading bit torrents. He did, not just one but two! So, after two three days of testing the problem in fact was the bit torrent download technology. ![]()
I went through 3 Linksys routers and now Cisco 831 but problem with bittorents and extremely slow internet does not go away. Of course with linksys, you cannot see what is going on on the router which would slow down your connection as soon as you open your bit torrent client. One thing which is different between cisco 831 and linksys is that with linksys the internet connection was DEAD and the router had to be reset in order for it to come online again but cisco831, the connection does slow down intially but gains speed after few minutes into the downloads… perhaps, as soon as it validates the connections with other peer it goes back to normal operation.

As soon as I closed it, this:
So, if you experience slow connection/internet every now and then + you are download bit torrents… this could be your problem.
I was not able to reproduce this problem on non linksys/cisco routers. I did not have this problem with D-links three years back… who knows?
