i have a 400 kbps internet connection. i am using a dlink d-300 router for sharing my laptop and desktop i have a static ip when i buffer youtube videos directly without the router i get proper playback but when i connect it to my router and use it on my laptop the playback takes a lot of time. but i have noticed the download speeds in both of them is the same.there is no loss in speed while downloading files or torrents or even normal browsing.
