MikroTik RouterOS 7 Basic Internet Setup
Build a wired WAN-to-LAN setup with DHCP, a bridge, DNS, masquerade and explicit firewall protection.
Configure and troubleshoot RouterOS routing, NAT, firewalls, VLANs, Wi-Fi and LTE/5G connections.
Start with wired Internet setup, the Wi-Fi package split, or cellular selection. Commands name their RouterOS stack and assumptions. Keep a recovery path before applying a network change.

Build a wired WAN-to-LAN setup with DHCP, a bridge, DNS, masquerade and explicit firewall protection.
Use srcnat, masquerade and destination NAT correctly, including forward rules, connection tracking and hairpin behavior.
Understand input and forward chains, stateful rules, interface lists, IPv6 protection and safe rule placement.
Stage a trunk, access ports and a management VLAN while preserving a separate recovery connection.
Identify the RouterOS wireless stack before choosing a band, channel width, station mode or roaming configuration.
Understand RouterOS cellular controls, LTE aggregation, 5G NSA anchors and when a band or cell restriction is useful.
Select or restore LTE and NR bands with supported RouterOS properties while accounting for carrier aggregation and NSA anchors.
Read RSRP, RSRQ, SINR and serving-cell information, then use supported cell monitoring to compare radio conditions.
Choose the documented LTE cell-lock family, query supported locks and understand reset, handover and carrier-aggregation limits.
Understand the documented QNWLOCK 5G SA syntax, required fields, reset behavior and why it does not lock NSA NR cells.
Separate SIM and registration failures from APN, routing, DNS and radio-performance problems before trying locks.
A diagnostic workflow for interfaces, routes, DHCP, DNS, firewall counters and current or legacy Wi-Fi clients.
One A4 page of current /interface/wifi band selectors, package distinctions and channel-width syntax.
One A4 field reference for selected European-relevant LTE and NR bands, duplex modes, frequency ranges and RouterOS selectors.
