Title: QOS Problem
Post by: capy2008 on September 19, 2015, 01:10:20 PM
I have from my isp 500 Mbs download and 200 Mbs upload. If I set qos at 480 dw and 190 up in my speed test does not pass 92 Mbs upload and download. What is the problem?

Internet Service Provider and Modem Configurations

Remove any set devices from the QoS priority sections, save settings and reboot then speed test again. Use wired LAN cable for speed testing.

There's some debate on weather QoS is really needed on ISP speeds over 100Mb.

I wait update, it is nice to see some feature like stream, gaming, share and others.

he he ... sounds like you encountered a similar issue to me ... I am still yet to convinced that the DIR-880L throughput limitation is linked to the "QOS issue" ... suspecting it is actually a router (or it's firmware) limitation.
Evidence was personal testing using my cable connection into a modem/router - where the back-end DIR-655 delivered ~105Mbps from the WAN but the "new" dir-880L delivered only 85mMbps with the same connection.
It's been reported on the interthing in other places and on these forums.

Does anyone have newer information (ie comparative testing) using the latest 1.05b02 firmware ?
