I want to have smooth browsing even when downloading something in the background. I have these settings set but web browsing still doesn't seem to be as responsive as when i'm not downloading anything. It feels the same as when i have QoS disabled. Is there anything i can do to improve my settings? My maximum upload is 256kbps, i read to set this at 90% for QoS. My router is WRT54G v5. Port 119 is for Usenet and Port 41706 is Utorrent. Both of the mac addresses i've given low priority to are my sister's two computers which connect by wi-fi.
