Good evening.  I worked with my ISP on the phone for a few hours to correct speed issues (have had for a long time, and just got fed up) and we were able to isolate the issue to something with my router, if you could please offer some ideas on what I may be doing wrong...The story - I pay for 600 Mps and get 50-80 down and ~20 Up when I conduct ISP speed test on my PC, harwired through either of a cat 5e or 6 cable to my router.  When I remove the router from the equation and plug computer into ISP modem, I jump up to 580up/~300down.  //  I verified my QoS settings on the modem are 1000mbs up and down and had wi-fi off with no other connections when conducting the test, but continue to get the low speeds through the router only.  I updated my firmware some time ago.  Do you have any ideas?  An acquaintance of mine at the ISP company told me to work with TPLINK to figure out what I need to do next.  Thank you
