Turn off QOS? I bought this router for this function. I have VoIP,WWW server, FTP server and much more, without QOS network is overloaded. Where is the point to buy more expensive hardware with extra function if I can not use them?
After years with this same problem I see no reason why I should buy dlink in the future,and expect that perhaps in 5-6-7 years perhaps they fix it. It is problem with firmware not settings, you can fix a bit with settings but it is no a point. Better result than turn-off QOS you may expect limiting upstream by 15-25%.
