Hi
Today I bought brand new TX3000E based on Intel 6E 210 chipset. No problems with installation.
The problem is with data transfer. On this card I got approx. max 50Mb/s, when on my phone 150-190Mb/s - the same localization
Checked connection: 5GHz. Even more, the same low transfer is with connection 1200/1200Mb/s I got once!
I got two TP-Link routers, FW of course up to date, AX10 and AX23. I read all your answers to similar problem, tried solutions, but non worked:
- router's Smart connect ON and OFF (2,4 and 5GHz together and separated)
- router's different channel
- router's different channel width
- card's new Intel drivers
- disconnecting and connecting antenna
I tried on both routers, moved them to the same room (2m from card antennas), one router enabled at a time.
Connection and speed

Test result with 200/20Mb/s download / upload internet connection (phone gets almost 200)

My desktop info below:
Intel driver

Asus B450M-A II mobo

Windows 11 Home 64bit

TP-LINK AX10



I still can return device to shop and get refund, but I want to try to make it work. Any suggestions?
EDIT: never mind, I returned card to the shop, but I leave this post just to refresh the problem.
