I have a laptop with a proprietary Intel wifi card that I am trying to use to connect to a WPA/WPA2 network (called simply Network)I've installed iwlwifi, net-tools, and network-managerI ran nmtui to set up the wifi, and all seemed well, and nmtui reported it was connected, but when I tried to ping 8.8.4.4 I got an unreachable network. For some reason nm[cli|tui] does not work. I've also tried wpa_supplicant, but wasn't able to get very far with that either.I'm hoping that there's some error in how I've set up my wireless interface that someone can spot and help me fix.I know that Network works because I am duel-booting Ubuntu alongside the Debian system and I have wifi working with Ubuntu.iwconfigwlo1      IEEE 802.11  ESSID:Network            Mode:Managed  Frequency:2.442 GHz  Access Point: A2:63:91:25:81:67             Bit Rate=72.2 Mb/s   Tx-Power=22 dBm             Retry short limit:7   RTS thr:off   Fragment thr:off          Power Management:on          Link Quality=53/70  Signal level=-57 dBm            Rx invalid nwid:0  Rx invalid crypt:0  Rx invalid frag:0          Tx excessive retries:0  Invalid misc:1   Missed beacon:0nmcliwlo1: connected to Network    Intel Wireless 3165 (Dual Band Wireless AC 3165)    wifi (iwlwifi), B8:81:98:51:75:5C, hw    ip4 default    inet4 192.168.1.23/24    inet6 fe80::bd90:9bfa:c408:e458/64enp1s0: unmanaged    Realtek RTL8101/2/6E PCI Express Fast/Gigabit Ethernet controller    ethernet (r8169), EC:8E:B5:A3:5C:02, hw, mtu 1500lo: unmanaged    loopback (unknown), 00:00:00:00:00:00, sw, mtu 65536DNS configuration:    servers: 192.168.1.1    interface: wlo1Use nmcli device show to get complete information about known devices andnmcli connection show to get an overview on active connection profiles.Consult nmcli(1) and nmcli-examples(5) manual pages for complete usage details.nmcli device showGENERAL.DEVICE:                         wlo1GENERAL.TYPE:                           wifiGENERAL.HWADDR:                         B8:81:98:51:75:5CGENERAL.MTU:                            0GENERAL.STATE:                          100 (connected)GENERAL.CONNECTION:                     NetworkGENERAL.CON-PATH:                       /org/freedesktop/NetworkManager/ActiveConnection/6IP4.ADDRESS[1]:                         192.168.1.23/24IP4.GATEWAY:                            192.168.1.1IP4.DNS[1]:                             192.168.1.1IP6.ADDRESS[1]:                         fe80::bd90:9bfa:c408:e458/64IP6.GATEWAY:                            --GENERAL.DEVICE:                         enp1s0GENERAL.TYPE:                           ethernetGENERAL.HWADDR:                         EC:8E:B5:A3:5C:02GENERAL.MTU:                            1500GENERAL.STATE:                          10 (unmanaged)GENERAL.CONNECTION:                     --GENERAL.CON-PATH:                       --WIRED-PROPERTIES.CARRIER:               offIP4.ADDRESS[1]:                         192.168.1.35/24IP4.GATEWAY:                            192.168.1.1IP4.ROUTE[1]:                           dst = 169.254.0.0/16, nh = 0.0.0.0, mt = 1000IP6.ADDRESS[1]:                         fe80::ee8e:b5ff:fea3:5c02/64IP6.GATEWAY:                            --GENERAL.DEVICE:                         loGENERAL.TYPE:                           loopbackGENERAL.HWADDR:                         00:00:00:00:00:00GENERAL.MTU:                            65536GENERAL.STATE:                          10 (unmanaged)GENERAL.CONNECTION:                     --GENERAL.CON-PATH:                       --IP4.ADDRESS[1]:                         127.0.0.1/8IP4.GATEWAY:                            --IP6.ADDRESS[1]:                         ::1/128IP6.GATEWAY:                            --nmcli connection showNAME      UUID                                  TYPE             DEVICE Network   21931e14-0cda-46b2-91c2-120447e287bd  802-11-wireless  wlo1   SAndroid  62d7a99d-8ef7-404c-b18b-df31ebb3b7bc  802-11-wireless  --     cat /etc/network/interfaces# This file describes the network interfaces available on your system# and how to activate them.
