# Temporary fix for Dell XPS 14/16 on Panther Lake
# Disable WiFi 7 (EHT/802.11be) on Intel BE200/BE211 cards
# The iwlwifi driver has a broken EHT RX data path — APs drop to MCS 0 NSS 1
# when EHT is negotiated, making WiFi unusable. Disabling EHT falls
# back to WiFi 6 (HE/802.11ax) which works at full speed.
# This should be removed when Intel fixes the firmware/driver.
