Hi,

I need some help for troubleshooting a problem of data transfer being limited at 100Mbps in a Windows 10 computer.


Archer C8 details
Firmware: 3.17.0 Build 20150515 Rel.34700n
Hardware version: ArcherC8 v1
5Ghz set up as "11ac only"

Archer T9E
Driver Version: 6.30.223.228
Driver Date: 02/05/2014
Windows 10 with latest patches
Motherboard ASUS P5Q
No tweaks in driver settings

-----
- Windows 10 recognizes T9E card correctly as "AC" and i'm able to connect in 5Ghz network as "11ac only";
- Windows 10 shows the wireless connection as "AC" in task manager;
- Windows 10 is only able to see 5Ghz network if it is set as "United Kingdom" country on Archer C8
- During the file transfer the magnetic disk reach maximum of 30% of usage (not tried transfer file from my SSD drive);
- Updating to the latest driver version (Archer T9E_V1_151026) Windows 10 is not able to see 5Ghz network
- I'm copying files to an USB 3.0 hard drive connected into the Archer C8.


Any idea why the maximum transfer data is 100Mbps?
