This behavior strongly suggests a firmware-level incompatibility or defect, where: Windows proprietary driver initializes the CNVi device correctly Linux iwlwifi driver fails due to incomplete or faulty firmware response This issue is documented across multiple Dell Precision models and is not fixable from the OS side. =E2=9C=85 Conclusion Wi-Fi hardware is not reliably Linux-compatible in current firmware state The issue is hardware/firmware related, not software Requires BIOS firmware fix, hardware replacement, or external Wi-Fi solution --=20 You may reply to this email to add a comment.
