+# 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.
