This trick works like gem for 24 Online Client users, and doesn't involve any great cheat or concept. Just that some ports remain open even after you exit the software.
So lets begin
* You should have Internet Download Manager installed in your machine. Get it from: http://katz.cd/search/internet+download
* Inser links in it..like rapidshare download links, and start downloading.
* If you have limited the download speed, remove download speed limit, and wait for all parts in IDM to receive data.
* when all parts start receiving data, just right click 24 Online Client in right side of the task bar and EXIT it.
After sometime, you will notice a whopping increase in the downloading speed. I am using an 128kbps internet connection, and I normally receive a downloading speed of 250KB/s
When IDM shows SEND Get, relogin again in 24 Online Client, wait until all parts start receiving data again..and then again EXIT the program.
I know its a repeating process, but as long as you are getting sexy downloading speed...Labour should hardly matter to you
