 If the Librem 5 won't connect to your network, [verify that the phone's date, time, and time zone are set correctly](https://forums.puri.sm/t/why-is-there-no-wifi/11107) in `Settings` > `Details` > `Date & Time`. At present, it's necessary to turn off the automatic date/time settings and set these manually. After successful connection, you can return the settings to automatic. If you're using MAC filtering on your router, don't forget to allow your Librem 5 in the router settings first. Using hidden SSID on your router may cause intermittent disconnection.

 First, find an appropriate icon, edit it if desired, name it (e.g. modem.png), and save it to `.local/share/icons`, creating the `icons` folder if it doesn't exist already.

 Next, to enable the app screen launcher to run `mmcli --modem=0` (or `mmcli --modem=m any`), copy the following text into the `ModemInfo.desktop` file, which was created previously in `.local/share/applications`:
 
-[Desktop Entry]
-Name=ModemInfo
-Exec=gnome-terminal -x bash -c “mmcli --modem=0 | tee modeminfo.txt; exec bash”

 The above automates opening the terminal, running the command, and also saves the terminal output to a text file (`modeminfo.txt`) in the home folder, as well as setting the icon to use as the launcher, all from a single tap on the app icon. The text file will be overwritten every time.
 
 At this point, either view the output in the terminal opened by the launcher, or close the terminal and view the text file instead.
