MikroTik WiFi & Legacy Wireless Settings

Start with the installed driver

Wi-Fi 5 is the awkward boundary: package availability depends on the chipset, architecture and device. An ac product name alone is insufficient. Package changes can require a configuration migration; do not uninstall a working driver remotely just to make a copied command available.

Bands, widths and country

A value such as channel.band=5ghz-ax selects a frequency/standard family. The radio capability list limits what is usable. 6ghz-ax means Wi-Fi 6E operation; 6ghz-be is Wi-Fi 7 on 6 GHz. Neither assigns a throughput guarantee.

For a compatible 5 GHz radio named wifi1, the following limits maximum width to 40 MHz and sets the installation country to Finland. Apply only at a Finnish site and with a wired management path; a radio change disconnects clients.

Use 20 MHz on crowded 2.4 GHz networks as a starting point. On 5/6 GHz, wider channels trade channel reuse and interference exposure for possible peak rate. channel.frequency is a set of candidate control-channel frequencies in MHz; it is not a request to bypass country rules. DFS channels may require a channel-availability check and must move after radar detection.

AP, station and roaming

An AP advertises a network; a station joins one. In current wifi configuration, mode=station identifies the client role. Set the intended SSID and security profile as well. Transparent bridging over a station link depends on supported station mode and the peer implementation; an ordinary three-address client association is not a universal Ethernet bridge.

Roaming involves client decisions plus optional AP assistance such as neighbor information and BSS transition requests. Cutting transmit power too far or aggressively rejecting low-RSSI clients can create a coverage hole. A high transmit power at the AP does not improve a weak client’s return transmission.

BSSID and connect-list: do not borrow legacy commands

A BSSID identifies a basic service set, typically an AP radio/SSID instance. In the current wifi manual, mac-address sets the interface’s own MAC/BSSID; it is not a remote AP-lock setting. No current wifi connect-list equivalent was verified for this guide, so legacy connect-list commands are not offered as current wifi instructions.

The legacy /interface/wireless/connect-list controls station connection selection and can match a remote AP MAC. Its rule order and default authentication behavior matter. An AP access-list controls clients joining the AP, which is a different direction. Check the legacy manual before changing those rules; a BSSID restriction can remove failover when the selected AP is unavailable.

Compare received signal in dBm, negotiated rates, retries and channel use while traffic is active. −55 dBm is stronger than −75 dBm, but neither alone establishes a usable MCS or throughput. A 2-stream client remains limited to its own stream count even on a larger AP. Compare a local wired server test at a fixed position before and after one radio change.
