Not working with USB 3.0
So i got the Ac1900 a7000 today and when i plug it into my USB port 2.0 and 3.0 they are both the same speed like I am not seeing a difference in using port 3.0 at all (speed at 866.7 Mbps) and i bel...
I am connecting it to a xfinity router don't know the specific one but it's a good one and my speeds for 5 amd 2.4GHz are the same which is like 866.7 Mbps that's what I was asking why is it not working better on my USB 3.0
Also I am noticing that it slows down alot like the wifi will get super slow and sometimes even disconnect any way to fix that. Also I am not too far from the main wifi router maybe 100 feet and the obstacle in the way is a wall.
A couple things.
1. 100 ft is quite a distance. Especially indoors. And 5ghz signal/speed drops off faster than 2.4ghz. So you're speeds will be much lower to the point the usb 2.0 or 3.0 interface isn't the bottleneck.
2. The router is important. If you're using an old/bad/cheap router, the wireless card wasn't the bottle neck
3. I doubt both the 2.4ghz and 5ghz are connected at 866mbps. because the A7000 supports 600mbps link on 2.4ghz and 1300mbps link over 5ghz
4. Link speed is not the same as throughput speed. Throughput speed for 5ghz tends to be 55-65% of what the link speed is. 2.4ghz is much much worse.
So your bottleneck probably isn't the usb interface. Its both distance, router, band used, and understanding of bands.
Try this method to stop the disconnects.

Or just do a clean install on the driver
- Both my speeds are like for 2.4 amd 5 GHz because right now my USB is plugged into a 2.0 port amd I am getting that much 866.7 and when I plug into a 3.0 port its the same the sketchy thing is that it dosent even chnage .1 it's exactly the same and I can stare at it for 5mins and the Mbps still wount change.
- My main wifi router is a good one and pretty latest about 2- years new and everything else works super fast even on my internet speed tests its fantastic even speed tests with the A7000 it says really fast but dosent show it sometimes
