I want to implement Bandwidth Control to be sure my internet phone adapter, Grandstream HT801, gets priority. The instructions say bandwidth is allocated by ISP address. I have the phone adapter...

@JJMartin Thanks. I am going to return this router to Amazon, and point out their description is somewhat misleading.

I just bought a TL-WR841N router. I want to set Quality of Service for the ethernet port used by my telepnone adapter, to ensure my phone always works. How can I do this?
