	=== Activity LED on Mikrotik ===		=== Activity LED on Mikrotik ===
		+	Certain version of Mikrotik routers have "User" or "Activity" LED. This LED can be defined in configuration and indicate "status" of something. I use this LED to indicate status of network connection via USB modem in my configurations.
		+
		+	* Verify that <code>user-led</code> is not used in configuration. If yes, then remove configuration for it:
		+	<pre>
		+	> /system leds print
		+	</pre>
		+
		+	* Add configuration indicating status of ppp client interface:
		+	<pre>
		+	/system leds add interface=ppp-wan leds=user-led type=interface-status
		+	</pre>
		+
		+	User / Activity LED will be lit when connection is established and dark when connection fail / disconnect.

	=== SMS reception ===		=== SMS reception ===
		+	SMS reception is possible but will block access to "info" details while enabled. Consider disabling if it is not necessary or if you need access to "info" details.
		+
		+	* Make sure that SMS is disabled before configuring:
		+	<pre>
		+	/tool sms set receive-enabled=no
		+	</pre>
		+
		+	* Set strong password to prevent remote script execution:
		+	<pre>
		+	/tool sms set secret=<password>
		+	</pre>
		+
		+	* Set port and retention configuration:
		+	<pre>
		+	/tool sms set port=Orange channel=2 keep-max-sms=5
		+	</pre>
		+	'''Note:''' Too many messages kept on modem may cause modem to stop receiving SMS at all. I am not sure what is limit for this modem but number bellow 10 is generally safe for all configurations.
		+
		+	* Enable reception:
		+	<pre>
		+	/tool sms set receive-enabled=yes

 Automatic selection is working fine when modem "see" strong network signal. Unfortunately this is not case when modem is installed in area with poor reception. Modem tend to jump around all access technologies under this condition. Transition between 2G and 3G is smooth but this is not case for 4G in our area (Slovakia). Each transfer to and from 4G network will cause modem to hung up and line connection needs to be re-established. It is really annoying if it is happening frequently. Clear indication of this is rapid color change of status LED and network disconnect caused by "modem hung-up".
