Hello, I got new hardware. Among the new stuff, there was one Intel® Dual Band Wireless-AC 3160. When I tried to connect to one (in fact any) of my networks, I was getting the following errors: [ 1021.092378] iwlwifi 0000:01:00.0: Microcode SW error detected. Restarting 0x82000000.

I disabled "CONFIG_IWLWIFI_BCAST_FILTERING" option and the 3160 is now working. As far as I can tell, there is already a firmware feature flag: "IWL_UCODE_TLV_FLAGS_BCAST_FILTERING" which can be used to distinguish whenever the feature is supported or not. But it seems to be "stuck on" for the 3160. Regards Christian BTW: I also tried the older "23.214.9.0" firmware too. => Same result [Doesn't work with BCAST_FILTERING enabled]. --- [ 989.779548] iwlwifi 0000:01:00.0: Detected Intel(R) Dual Band Wireless AC 3160, REV=0x164 [ 989.779753] iwlwifi 0000:01:00.0: L1 Enabled; Disabling L0S [ 989.780191] iwlwifi 0000:01:00.0: L1 Enabled; Disabling L0S [ 989.882439] ieee80211 phy2: Selected rate control algorithm 'iwl-mvm-rs' [ 1021.092378] iwlwifi 0000:01:00.0: Microcode SW error detected.
