Question Slow Speed Test

[tosbourne88]

Hello everyone. I am having slow speeds on all my PC's. 5Ghz connection and LAN connection are both getting around 70-80 Mbps down with a 10Mbps up. I have a 350 Mbps connection. Our phones are connecting at just over 300Mpbs down, anywhere in the house. Not really sure what is causing this. Any ideas?

Edit*
I have a custom built PC with a Asus AC68 PCIe card.

70-80mbps sounds like it's connected as wirelessN, not wireless AC.

What router do you have, can you try disabling 2.4ghz or set it to wireless AC only to test out and get a data point?
