Hey, guys, I have a slow downloading issue with my killer Wifi 6E AX690i; only with download, the upload speed is fine I get about 1m downloads and upload over300m. my other laptop is fine my phone is fine I tried things like
- "netsh int tcp set global autotuninglevel=normal" - nothing fixed
- install different drivers, change the config on the WIFI card and did many tests in different ways but still have the issues - nothing fixed
I tried the same WIFI card on another windows 10 laptop and it worked fine I tried a different card AX210 on my laptop, and it worked perfectly; the issue is only on my laptop, and windows 11
one of my tests connecting a USB C network adapter and i noticed the same slowness it looks like this USB c and the WIFI Card are connected to the same controller and BUS , Intel Alder Lake-P/M PCH - USB 3.2 Gen 2x1 (10 Gb/s) xHCI Host Controller and Intel Alder Lake-P/M PCH - PCI Express Root Port #5 so it might be something wrong with windows 11 and the intel controller and BUS
