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


********** attaching some photos



I need help, please
 


It seems you've explored various troubleshooting steps to address the slow download speed with your Killer Wifi 6E AX690i on your Windows 11 laptop. Since the issue is specific to this laptop and possibly related to the hardware controller, here are some additional steps you can take:

1. Update Drivers:
- Ensure all your drivers, especially those related to the network adapter and motherboard, are up to date.
- Visit the manufacturer's website for your laptop and motherboard to download and install the latest drivers available.

2. Check Power Settings:
- Make sure that your power settings are optimized. Set them to High Performance to ensure maximum performance and minimal power saving, as certain power-saving modes can affect network performance.

3. Network Troubleshooter:
- Run the network troubleshooter in Windows. Sometimes it can detect and fix common connectivity issues automatically.

4. Network Reset:
- You can try resetting your network settings. Go to Settings > Network & Internet > Status > Network Reset.

5. BIOS Update:
- Check if there is a BIOS update available for your laptop. Sometimes BIOS updates can resolve hardware-related issues.

6. Check for Interference:
- Ensure there's no interference from other wireless devices or networks that could be affecting your Wifi connectivity.

7. Contact Support:
- If the issue persists, you may want to reach out to the laptop manufacturer's support for further assistance, especially if the problem seems specific to the laptop's hardware and its interaction with Windows 11.

By following these steps and possibly delving deeper into the hardware configuration on your laptop, you might uncover the specific cause of the slow download speeds and find an effective solution.
