Hi everyone,

I am having an Upload speed issue with my newly installed TP Link Archer T4E. My config is as followed:
Motherboard: Asrock s97m Pro4
CPU: Intel i5-4590
Ram: 32 GB DDR3
OS: Windows 10 Pro 64bits

Since my motherboard does not have an integrated Wifi card, I decided to buy a PCI-E Wifi card and choose the TP Link Archer T4E.
After installing the card and running a few speedtest, I am getting the expected download speed (30mbps) but my upload speed is very slow (below 2Mbps). I have tried many drivers since I read there are many drivers issue with the TP Link drivers and Windows 10 but the issue still persists. I am right now using the 2024.0.2.101 version (from 18/04/2018). My router does not seems to be the issue since all my other devices are able to achieve the expected 30Mbps Download and 30Mbps Upload.

Does anyone have an idea of what could be the issue?

Thanks in advance.
