Introduction The author introduces the topic of configuring a Mikrotik device and mentions that some experts criticize unnecessary settings. However, he believes that basic configuration is necessary for normal operation.

Basic Configuration The chapter explains how to download and use the Winbox tool to manage Mikrotik devices. The author emphasizes the importance of resetting default configurations before setting up local networks, DHCP servers, DNS queries, user accounts with full privileges while deleting admin accounts.

Local Network Setup This chapter covers creating new user accounts with passwords on a separate network interface from admin access points using dynamic IP addresses assigned by DHCP server or static IPs manually set in TCP/IP properties. It also discusses cellular connectivity issues such as signal strength levels displayed in dBm units when connecting via LTE modem firmware updates available online at LG's website if needed

Factors affecting signal quality The main factor affecting the quality of a mobile network is the level of signal received from the base station, which can be measured by parameters such as SRP and RSRQ. The higher these values are, the better the signal quality will be.

Updating modem firmware To update modem firmware, users should check for new versions in their device's interface and download them remotely if necessary. It is important to not interrupt this process once it has started to avoid losing connection with your provider.

DNS server settings Users should manually add two DNS servers when configuring their profiles on LTP NS interfaces to ensure that they have internet access even if internal operator DNS servers fail or do not provide connectivity. These settings can also affect dynamic IP addresses assigned by providers during downlink/uplink transitions.

Setting up DNS servers The author discusses setting up public DNS servers from Club Flyer and Google, which have not caused any issues. They also mention configuring the default gateway on their Mikrotik router.

Security settings The author goes over security settings in the firewall tab of their Mikrotik interface, including using source chains and dynamic IP addresses for mobile providers to protect against external threats.

Updating firmware The author updates the firmware on their router by downloading a new version of RouterOS through the interface. They check that all systems are updated before rebooting and verifying that everything is working properly.
