Hi all, first of all thanks for helping to find a solution. In the PC of a friend I installed Crux-3.4 with plasma 5 (KF5). Nearly everything seems to run without problems, but wifi doesn't. However: # lspci -k Network controller: Realtek Semiconductor Co., Ltd. Device b822         Subsystem: Hewlett-Packard Company Device 831b         Kernel driver in use: r8822be         Kernel modules: r8822be but: # ifconfig -a : no inet address! both configuring through wpa_cli that through wpa_passphrase # dmesg | grep error:     platform regulatory.0: Direct firmware load for regulatory.db failed with error -2                       cfg80211: failed to load regulatory.db I installed CRDA, but I don't get regulatory.db and regulatory.db.p7s in /lib/firmware. Furthermore, I red that both regulatory.db and .p7s are now directly built into the kernel, and so crda is no more necessary. # iw reg get global country 00: DFS-UNSET         (2402 - 2472 @ 40), (N/A, 20), (N/A)         (2457 - 2482 @ 20), (N/A, 20), (N/A), AUTO-BW, NO-IR         (2474 - 2494 @ 20), (N/A, 20), (N/A), NO-OFDM, NO-IR         (5170 - 5250 @ 80), (N/A, 20), (N/A), AUTO-BW, NO-IR         (5250 - 5330 @ 80), (N/A, 20), (0 ms), DFS, AUTO-BW, NO-IR         (5490 - 5730 @ 160), (N/A, 20), (0 ms), DFS, NO-IR         (5735 - 5835 @ 80), (N/A, 20), (N/A), NO-IR         (57240 - 63720 @ 2160), (N/A, 0), (N/A) /etc/localtime is a link to Europe/Rome. # grep crda /var/log/messages     gives no message Googling, I found the suggestion to create /etc/sysconfig/regdomain and putting into: COUNTRY=IT. But when I reboot nothing changes. I think that this file is not a system file in Crux. Question: how could I correct "country 00: DFS-UNSET" to "country IT: DFS-ETSI"? Many thanks. Giorgio Cittadini
