Hi, I have an old desktop machine with Debian 11, running fine, as usual. Recently I bought a USB/Wi-Fi dongle/adapter to connect it to my home WLAN. The chipset and correspondent firmware blob seem to be the 'MediaTek MT7601U firmware, version 34 (mt7601u.bin)', available in the `firmware-misc-nonfree` package.
After reading: https://wiki.debian.org/NetworkConfiguration https://www.debian.org/doc/manuals/debian-handbook/sect.network-config https://www.debian.org/doc/manuals/debian-reference/ch05.en.html https://wiki.debian.org/WiFi https://wiki.debian.org/Firmware https://wiki.debian.org/WiFi/HowToUse , and some linked pages, I installed `firmware-misc-nonfree`, rebooted, and configured the interface like this: $ iwctl [iwd]# station wlan4 connect "Fibertel WiFi238 2.4GHz" Input passphrase and done. I'm connected. [iwd]# station wlan4 show Station: wlan4 * -------------------------------------------------------------------------------- Settable Property Value -------------------------------------------------------------------------------- Scanning no State connected Connected network Fibertel WiFi238 2.4GHz ConnectedBss b8:66:85:fd:0a:d1 Frequency 2462 Security WPA2-Personal RSSI -77 dBm AverageRSSI -76 dBm RxMode 802.11n RxMCS 4 TxMode 802.11n TxMCS 4 TxBitrate 43300 Kbit/s RxBitrate 39000 Kbit/s ExpectedThroughput 15937 Kbit/s Then: $ sudo nano /etc/network/interfaces , and added: ``` allow-hotplug wlan4 iface wlan4 inet dhcp ``` And then: $ sudo ifup wlan4 And done. Everything seems to be working perfectly. I've got this: $ cat /etc/resolv.conf domain fibertel.com.ar search fibertel.com.ar nameserver 192.168.0.1 $ ip route list default via 192.168.0.1 dev wlan4 192.168.0.0/24 dev wlan4 proto kernel scope link src 192.168.0.168 $ ip link show 1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN mode DEFAULT group default qlen 1000 link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00 2: enp0s7: <BROADCAST,MULTICAST> mtu 1500 qdisc pfifo_fast state DOWN mode DEFAULT group default qlen 1000 link/ether 6c:f0:49:9b:b5:13 brd ff:ff:ff:ff:ff:ff 11: wlan4: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state UP mode DORMANT group default qlen 1000 link/ether 20:e9:17:0d:5d:9e brd ff:ff:ff:ff:ff:ff $ sudo ifconfig lo: flags=73<UP,LOOPBACK,RUNNING> mtu 65536 inet 127.0.0.1 netmask 255.0.0.0 inet6 ::1 prefixlen 128 scopeid 0x10<host> loop txqueuelen 1000 (Local Loopback) RX packets 71 bytes 9188 (8.9 KiB) RX errors 0 dropped 0 overruns 0 frame 0 TX packets 71 bytes 9188 (8.9 KiB) TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0 wlan4: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500 inet 192.168.0.168 netmask 255.255.255.0 broadcast 192.168.0.255 inet6 fe80::22e9:17ff:fe0d:5d9e prefixlen 64 scopeid 0x20<link> ether 20:e9:17:0d:5d:9e txqueuelen 1000 (Ethernet) RX packets 66525 bytes 17810025 (16.9 MiB) RX errors 0 dropped 0 overruns 0 frame 0 TX packets 72346 bytes 12467100 (11.8 MiB) TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0 All this seems OK? I'm asking because the Debian wiki proposes (I think) two different schemes: - ifupdown with wpasupplicant, iw, wireless-tools, etc. - iwd enabling `EnableNetworkConfiguration=true` in /etc/iwd/main.conf and setting the name resolving service with `systemd-resolved` , and I did neither: $ systemctl status systemd-networkd.service ● systemd-networkd.service - Network Service Loaded: loaded (/lib/systemd/system/systemd-networkd.service; disabled; vendor> Active: inactive (dead) TriggeredBy: ● systemd-networkd.socket Docs: man:systemd-networkd.service(8) , but apparently a mix between both schemes (my "understanding" of the situation is that iwd creates/manages the connection between the adapter and the router, and ifupdown with /etc/network/interfaces sets/configures the interface for the system and the DNS resolution, because I never installed the `resolvconf` package). Now, is this proper/right/reliable? Should I do something different? Is it normal/irrelevant that I receive once and again the local IP address 192.168.0.168 (meaning, the last one of all)? And finally: if this is another possible/simpler solution, should I (or anyone better equipped) add it to the wiki for other people's use? Thanks a lot in advance and I desire everybody a wonderful year's beginning!
