@alex89 Hi good day

 

Thanks for your detailed information. 

 

Please force 5Ghz Wireless Mode to ’802.11ac ’on Adapter Properties settings as the photo attached. 

If your router has AES only encryption on 5Ghz wireless settings, please change to AES only instead of AES/ TKIP 

 

Here is the chipset driver for Archer T4E, please give it a try:

If still the same problem, can you let me know the Model number of your D- Link router, and share a photo of your router 5Ghz Wireless settings? 

Please also attach a photo of the 5Ghz link speed, thank you.

@Solla-topee 

Thank you for the reply.

I tried everything you suggested, but it didn't work. The drivers you provided are for USB wireless adapters. Mine is PCIe. I downloaded the as well from the Realtek site but neither of them resolved the issue. 
 

My system contains:
COVR 1102 ac1200 and
DAP 1620 ac1300 wifi range extender (compatible with mesh system)

 

My PC is connected to the extender.
I tried to connect my phone to the extender and the wifi download speed was about 80Mb/s (My PC is only getting 20 Mb/s). Then I made a hotspot of the phone and connect the PC to it, but the speed gets even lower, about 13Mb/s. That's how I determined that the issue is with TP-LINK ARCHER T4E AC1200 on my PC.
Wireless settings on mesh router:


I am using the latest official driver from the TP-Link site.

@adete 
Hi all,

I manage to solve the issue. After installing the driver I went to the Network Connections (Win 10) -> double click on my Wi-Fi network -> Wireless Properties -> Security tab.

  1. Set Security type to WPA2-Personal
  2. Set Encryption type to AES

After saving (Click Ok) my Wi-Fi properties looks like:


...
Protocol:    Wi-Fi 5 (802.11ac)
Security type:    WPA2-Personal
Network band:    5 GHz
Network channel:    36

Link speed (Receive/Transmit):    866/866 (Mbps)
...
Manufacturer:    TP-Link Technologies Co., Ltd.
Description:    TP-Link Wireless PCI Express Adapter
Driver version:    2024.0.2.101
...

 

 

Thank you all for replays and support!

Cheers!
