I recently moved in to a new apartment and the house owner is providing the internet. He has 16 Mbps connection from his ISP (Deutsche Telekom). I am only able to connect to his infrastructure via wireless.
Whenever I am downloading any data from the internet, for example watching streamed video or downloading a file, the connection is very slow. Only about 50-100 KB/s.
But, if I am using some special software, like jDownloader or BitTorrent, which is set to get the source file with multiple connections, the download speed increases and often even reaches the limit of 16 Mbps.
For example, downloading latest NetBeans installer file, I get around 50 KB/s using Firefox (1 connection) and 500 KB/s or more using jDownloader (10 connections).
What could be the cause of this slow single connections?
Running a speed test on http://www.speedtest.net/ reports around 5.41 Mbps download and 0.90 Mbps upload with ping of 23.
I can imagine that the ISP is reducing the speed for single connections. I doubt that the house owner has any technical knowledge to reduce the connection speed and the used router is a simple router from the ISP with original Software (as far as I could tell from getting to it's login page).
I've tested this with multiple PCs and OS - there is no difference.
