Hello 1650ikillerError,

I hope you are having a good day.

Regarding this issue, let me also ask/gather the following details:

1. Do you have a background application that is using an internet connection?
2. What is the engine prioritization of the Intel Killer Performance Suite? Ask for the screenshot.
3. What frequency are they connected to? Is it 2.4, 5, or 6 Ghz?
4. Is there any other device connected to the same network that has the same issue? Or is the issue only isolated to his laptop?
5. Have you also tried using a different connection, such as a mobile hotspot or a different network?

Let me also add that we have a similar issue before, and this is what fixed the issue:

This is expected behavior. For example, Steam, or other app-launchers run as a Priority 4 by default, but the games, launched/ installed from Steam will have the default Priority 1. Priority settings can be manually changed in the Killer Control Center - Prioritization Engine section.

If you have questions, please let us know. Thank you.

1. Do you have a background background application that is using an internet connection? No
2. What is the engine prioritization of the Intel Killer Performance Suite? Ask for the screenshot. i dont understand
3. What frequency are they customer connected to? Is it 2.4, 5, or 6 Ghz? 5GHz
4. Is there any other device connected to the same network that has the same issue? Or is the issue only isolated to his laptop? only 1650i, INSTALLED mediatek usb wifi the problem dont exist, another device like android phone work well, ONLY 1650I HAVE THIS PROBLEM,
5. Have you also tried using a different connection, such as a mobile hotspot or a different network? yes and ONLY 1650i have this problem, this laptop install with another mediatek wifi dont have this problem, android phone dont have this problem, AMD laptop with mediatek wifi dont have this problem, and that is your fault to create a faulty card

[1650ikillerError]

I SAID again and again i dont see any problem with any usb wifi card or any devices i own, only this 1650i card, i replaced with mediatek card and install driver, no problems so far, yeah your wifi card products are faulty both 1550i and 1650i
