I have an OBI100. My router is a TP-Link TL-WR841N. TP calls QOS simply "bandwidth control." I have set my OBI with a static IP, which TP calls "IP reservation."
Once you enable bandwidth control you have to set global download and upload potential, which in my case is approx 20mb down and 2MB up. Then you set a rule for the device. I was told at some point that GV needs 100kbps up to function well, so I set that as my min up and download speed. Still wondering about what to use for maximum up and down. I experimented with 100kbps also but it seemed like I was having issues. I just changed my max up and down to 1024kbps, but I don't really know if that is correct either, though you would think a mb would do it.
You also need a port range for the device rule and a TP support person suggested just giving the full range of ports, 1 to 65535.
Anybody got suggestions for min and max up and down and port range?
Thanks!
