I am trying to create a WiFi hotspot (from the int connection) on a small test file server running a near stock CentOS 7 (the sort of unsupported 32bit AltArch version), but NetworkManager does not seem to want to manage the device:$ nmcli dev statusDEVICE       TYPE      STATE      CONNECTION    enp0s2       ethernet  connected  extenp3s1       ethernet  connected  int   lo           loopback  unmanaged  --            wlp0s2       wifi      unmanaged  --  I have tried adding managed=true to /etc/NetworkManager/NetworkManager.conf, and /etc/network/interfaces does not exist. I have tried creating various ifcfg files manually using nano, vim, nmtui and other methods (no GUI is currently available) - it does not recognise it automatically.How can I get NetworkManager to use the wifi device? It works on other computers, and though I could reconfigure the network with something else, there doesn't seem to be any obvious solutions I have found to get it to work (I have found lots of stuff on getting it to NOT manage devices).EDIT: Network manager does sort of recognise the custom ifcfg profile - it shows in nmtui profile editor (but not in the 'Activate Connection' bit), and when restarting the process it shows:Oct 21 18:05:53 HOSTNAME network[6076]: Bringing up interface USB-Hotspot:  [  OK  ]but does not seem to associate with the device despite having the correct MAC and interface addresses.EDIT2: Here is one of the inital files (/etc/sysconfig/network-scripts/ifcfg-USB-Hotspot - MAC etc blanked)HWADDR=XX:XX:XX:XX:XX:XXESSID=26-3MODE=ApKEY_MGMT=WPA-PSKTYPE=WirelessBOOTPROTO=sharedDEFROUTE=yesIPV4_FAILURE_FATAL=noIPV6INIT=noNAME=USB-HotspotUUID=36b6cb89-6f59-453a-84d9-1ef7ff35f187DEVICE=wlp0s2ONBOOT=yesWPA_ALLOW_WPA=yesWPA_ALLOW_WPA2=yesNM_CONTROLLED=yesMAC_ADDRESS_RANDOMIZATION=defaultZONE=publicI have just tried various other incantations of it as well, including this (based on the working config file off another computer, using the same wifi adapter):HWADDR=XX:XX:XX:XX:XX:XXESSID=wtopMODE=ApSSID_HIDDEN=yesTYPE=WirelessBOOTPROTO=sharedDEFROUTE=yesIPV4_FAILURE_FATAL=noIPV6INIT=noIPV6_AUTOCONF=yesIPV6_DEFROUTE=yesIPV6_PEERDNS=yesIPV6_PEERROUTES=yesIPV6_FAILURE_FATAL=noIPV6_ADDR_GEN_MODE=stable-privacyNAME=HotspotUUID=bb8842f3-79ae-4f9c-ae93-838d064e4fa4ONBOOT=noZONE=publicKEY_MGMT=WPA-PSKMAC_ADDRESS_RANDOMIZATION=defaultI when I first installed this ages ago I also had a problem that the NIC added post install was also not managed, but I reinstalled CentOS for something else and it worked then. I have got this sort of thing to work using NetworkManager and other things (hostapd, udhcpd, etc), but this is a bit odd. Also, nmtui: ]And when created manually I did do the required /etc/sysconfig/network-scripts/keys* files.EDIT3: This works on a laptop, same wireless adapter - weird:HWADDR=XX:XX:XX:XX:XX:XXESSID=testingMODE=ApKEY_MGMT=WPA-PSKSSID_HIDDEN=yesTYPE=WirelessBOOTPROTO=sharedDEFROUTE=yesIPV4_FAILURE_FATAL=noIPV6INIT=noIPV6_AUTOCONF=yesIPV6_DEFROUTE=yesIPV6_PEERDNS=yesIPV6_PEERROUTES=yesIPV6_FAILURE_FATAL=noIPV6_ADDR_GEN_MODE=stable-privacyNAME=USB-HotspotUUID=8b6a2f48-ab82-412d-bf22-36ec2120ff2aONBOOT=yesMAC_ADDRESS_RANDOMIZATION=defaultWPA_ALLOW_WPA=yesWPA_ALLOW_WPA2=yes
