Latitude 3520 very slow download but fast upload
Sir,
I have latitude laptop 3520 with windows 11 pro ver. 25H2.
So, i have trouble with network very slow download speed both wired and wireless.
i have tested speed test, download is about 17 Mbps and upload 104 Mbps.
i don't know that the problem came from OS or hardware.
I have tried to update driver to be latest version but still same problem.
So, this is WI-FI card configuration.
No Events found!

Hi
Can you please state what external type of connection you have, like a FIBRE, GigaBit or whatever please.
Is the ethernet a single direct cable?
Perhaps try a command like ....
ipconfig /all

So perhaps do a comparison in the setup of both.
ipconfig /all
tracert 13.107.4.52
ping 13.107.4.52
