Thanks for all the help so far. I've solved the firmware problem. The needed files weren't in the latest stable version of linux-firmware nor in the masked version (after much hassle unmasking it), but they are in both System Rescue + Mint /lib/firmware/mediatek . They are versions 7922 and 7961 with corresponding RAM_CODE files.
I copied them into the new machine in the same-named dir, 'unxz' them & after reboot 'dmesg' announced that it had loaded 7961 & 'ip a' showed a 4th interface 'wlp5s0'. So far, so good. What is still not good is that that interface has "NO-CARRIER". Also, 'rc-status' after a reboot shows wpa_supplicant as STOPPED. 'rc-service -v wpa_supplicant start' gets it STARTED, but 'ip a' still shows "NO-CARRIER". I tried 'ip link set wlp5s0 carrier on', but was told "operation not supported". w_s seems to be finding its conf file at /etc/wpa_supplicant/wpa_supplicant.conf , but 'wpa_cli' continues to say "can't link to wpa_supplicant". I have checked the service name + password are correct in the conf file. It's approaching supper time & I've run out of ideas for today anyway. Any further advice is most welcome (smile). -- ========================,,============================================ SUPPORT ___________//___, Philip Webb ELECTRIC /] [] [] [] [] []| Cities Centre, University of Toronto TRANSIT `-O----------O---' purslowatchassdotutorontodotca
