  - OpenWRT stable misses a patch to enable our board ethernet port -> we compile from source
  - The Modem Manager simtech plugin does not declare 5GNR

+
+## Flash OpenWRT from OpenWRT (!)
+
+Copy the firmware in router's `/tmp`.
+Why `/tmp`? Your router has more volatile storage than persistent one, moreover you will overwrite the persistent storage.
+So, copy the firmware in `/tmp`!
+Next, we will use the `sysupgrade` command. `-v` is verbose, `-n` ask openwrt to erase configuration files (ie. ask for a factory reset).
+
+```
+sysupgrade -v -n /tmp/openwrt-ipq40xx-generic-compex_wpj428-squashfs-sysupgrade.bin
+```
+
+## Get root on MimoAP
+
+  1. Download a backup from your router firmware
+  2. Extract it, edit `/etc/shadow`, replace the hash of the `root` user with the one from the `admin` user
+  3. Recompress the folder hierarchy
+  4. Import this new archive as backup in MimoAP
+  5. Run `ssh root@192.168.1.1` (replace with the IP address of your router) and use your `admin` password
+  6. Enjoy! (But you should really install a vanilla OpenWRT instead)

+## Using ModemManager
+
+Wait for modems:
+
+```
+mmcli -M
+```
+
+Connect/Disconnect:
+
+```
+mmcli -m 0 --simple-connect="apn=free"
+mmcli -m 0 --simple-disconnect
+```
+
+Set supported/preferred mode:
+
+```
+mmcli -m 0 --set-allowed-modes="3G|4G" --set-preferred-mode=4G
+mmcli -m 0 --set-allowed-modes="5G"
+```
+
+Equivalent with `qmicli`:
+
+```
+qmicli --device=/dev/cdc-wdm0 --device-open-proxy --nas-get-system-selection-preference
+qmicli --device=/dev/cdc-wdm0 --device-open-proxy --nas-set-system-selection-preference='5gnr|lte'
+```
+
+## QMICLI Connect
+
+About our provider (Free Mobile), IPv4 is acquired through DHCP but IPv6 is statically provided.
+
+### IPv6
+
+```
+qmicli --device=/dev/cdc-wdm0 --device-open-proxy --wds-start-network="ip-type=6,apn=free" --client-no-release-cid
+qmicli --device=/dev/cdc-wdm0 --device-open-proxy   --wds-get-current-settings
+ip addr add 2a0d:e487:15f:f7f5:5c58:4e37:90c0:74d8/64 dev wwan0
+ip route add default via 2a0d:e487:15f:f7f5:49ec:2e4a:ca1:5b20
+echo -e "nameserver 2a0d:e480::1\nnameserver 2a0d:e480::2" > /etc/resolv.conf
+```
+
+### IPv4
+
+```
+qmicli --device=/dev/cdc-wdm0 --device-open-proxy --wds-start-network="ip-type=4,apn=free" --client-no-release-cid
+udhcpc -q -f -n -i wwan0
+```
+
+## Error
+
+Despite patching ModemManager simtech plugin, we get an error if we force 5GNR.
+We typed:
+
+```
+mmcli -m 0 --set-allowed-modes="5G"
+mmcli -m 0 --simple-disconnect
+mmcli -m 0 --simple-connect="apn=free"
+```
+
+We got:

+## ModemManager
+
+We append the following to ModemManager:
+
+```
+config interface 'broadband'
+        option device '/sys/devices/platform/soc/60f8800.usb2/6000000.dwc3/xhci-hcd.1.auto/usb3/3-1'
+        option proto 'modemmanager'
+        option apn 'free'
+        option iptype 'ipv4v6'
+```
+
+Then we can start the interface with:
+
+```
+ifup broadband
+```
+
+Both IPv6 and IPv4 should work:
+
+```
+ping openwrt.org
+ping -6 openwrt.org
+```
