Hey, I see your issue clearly. You're using an ASUS ROG Zephyrus G15 with the Intel AX200 Wi-Fi card on Windows 11, and you're having trouble connecting to your TP-Link Ax73 router. The problem seems to depend on the Wi-Fi band settings—specifically, when the AX200 is set to 20MHz it works, but not at 40MHz or 160MHz. Also, it connects fine on 2.4GHz/5GHz bands. You mentioned trying driver updates and reinstalling the card, but it didn’t help. I’d like some more details or advice on what else you could try. Added a note with an image for reference.
20/40/80/160 on channel 40 was also attempted with a 20/40/80 channel width on channel 149, yielding identical outcomes. Updated March 22, 2023 by xkeith Correction from 10 to 20
