 for Upgrading MMDVM_HS_Hat board conected to GPIO you have to enter the command:
-<code>sudo pistar-mmdvmhshatflash hs_hat [Enter]</code>
+<code>sudo pistar-modemupgrade hs_hat</code>
 for upgrading the original MMDVM-HS_DUAL_HAT board (made by Andy, Florian (DF2ET) and DB9HAT) conected to GPIO  you have to enter the command:
-<code>sudo pistar-mmdvmhshatflash hs_dual_hat</code>
+<code>sudo pistar-modemupgrade hs_dual_hat</code>
 If you get a message that the flashing process was successfull, the hardest part is done. If not, repeat flashing or ask for help in the "MMDVM-BM" or "DAPNET User" Telegram-Messenger Groups.
+Newer board variants are equipped with a 12.288MHz TCXO and require a firmware with different settings. The commands above flash a 14.7456MHz firmware. To upgrade boards with a 12.288MHz use the following commands:
+<code>sudo pistar-modemupgrade hs_hat-12mhz</code>
+respectively
+<code>sudo pistar-modemupgrade hs_dual_hat-12mhz</code>
+Be sure to identify your TCXO before flashing the firmware!

+===== Troubleshooting =====
+Sometimes the DAPNETGateway-service got stuck when loosing internet-connection. This results in an error-state on the status-page of the transmitter at hampager.de. Unfortunately the service would be still running but not reconnecting.
+If you would like to implement a watchdog that restarts the service, if the transmitter goes into error-state you could use following script, that could be called every 5 minutes for example by crontab:
+        #!/bin/bash
+        RETVAL=$(curl -u <username>:<password> https://hampager.de/api/transmitters/<yourtransmittercallsign> | egrep -h "OFFLINE|ERROR" | wc -c)
+        if [ "$RETVAL" -gt 0 ]; then
+                sudo systemctl stop dapnetgateway.service > /dev/null 2>&1
+                echo restarting dapnetgateway
+                sleep 5
+                sudo systemctl start dapnetgateway.service > /dev/null 2>&1
+        fi
+Remember to switch the sd-card to read-write-access with ''rpi-rw'' before creating the file in your home-directory. Also remind to make it executable with ''chmod +x yourscriptname.sh''
+**Fehlerbehebung Telekom Router**
+Ein weiterer Fehler trat bei Telekom Routern auf.
+Die Router W922 V und W925 V (vielleicht auch noch weitere) haben eine Sicherheitseinstellung, dass sich regelmäßig die IP Adresse ändert.
+Dadurch wird die Internetverbindung zum MMDVM unterbrochen und nicht wieder neu aufgebaut.
+Durch ausschalten der der Sicherheitsfunktion im Router ist das Problem behoben.

+===== Working example =====
+The transmitter DM0HL is equipped with a MMDVM board and a Motorola GM380 (see [[9k6|9k6]] for pinout). Pictures provided by Michael DO1RL
