Recently I upgraded my notebook PCs (Lenovo ThinkPad E580 and Lenovo Legion Y530, both running Windows 11 Pro build 22000.832 with the latest updates installed) with Intel AX210NGW Wi-Fi cards.
Naturally, I downloaded the latest drivers from Intel’s website.
The main problem is… Upload speed of these cards is extremely low, approximately 5 Mbps on a 5 GHz ax network. Just for comparison, my Samsung Galaxy S22 Ultra can achieve almost 1000 Mbps on the same network and physical location.
Any ideas what could cause this issue? I tried swapping the cards, even performed a clean Windows install on one of the PCs. Needless to say, it didn’t help.
These are the settings in Windows Device Manager for the cards.
