Hello,

I yesterday bought a new TP-Link Archer C6 AC1200 Wireless MU-MIMO Gigabit Router for my new 140 Mbps connection. I'm getting great speed over wifi @ 5GHz mode. But when my PC is connected to the router using ethernet. For some wierd reason my Upload speed is very slow but my upload speed is alright.

I wanted to make sure that my ISP has no issues. So I even tested the speed results from my old  TP-Link Archer 750  router. Using my old router I got a good speed for both download and upload speeds.

Now all the test were done while wifi was turned off and all tests were done on same server. Also one wirless test done on 5Ghz network.

Here are the speed check results.
