Use WPA2 network with hotspot credentials

ℹ️ Info: This script can not be used on its own but requires the base installation. See main README for details.

Description

RouterOS supports an unlimited number of MAC address specific passphrases for WPA2 encrypted wifi networks via access list. The idea of this script is to transfer hotspot credentials to MAC address specific WPA2 passphrase.

Requirements and installation

You need a properly configured hotspot on one (open) SSID and a WP2 enabled SSID with suffix "-wpa".

Then install the script:

$ScriptInstallUpdate hotspot-to-wpa;

Configure your hotspot to use this script as on-login script:

/ ip hotspot user profile set on-login=hotspot-to-wpa [ find ];

Automatic cleanup

With just hotspot-to-wpa installed the mac addresses will last in the access list forever. Install the optional script for automatic cleanup:

$ScriptInstallUpdate hotspot-to-wpa-cleanup,lease-script;

Create a scheduler:

/ system scheduler add interval=1d name=hotspot-to-wpa-cleanup on-event="/ system script run hotspot-to-wpa-cleanup;" start-time=startup;

And add the lease script to your wpa interfaces' dhcp server:

/ ip dhcp-server set lease-script=lease-script [ find where name~"wpa" ];

Configuration

On first run a disabled access list entry acting as marker (with comment "--- hotspot-to-wpa above ---") is added. Move this entry to define where new entries are to be added.

Create hotspot login credentials:

/ ip hotspot user add add comment="Test User 1" name=user1 password=v3ry;
/ ip hotspot user add add comment="Test User 2" name=user2 password=s3cr3t;

Additionally templates can be created to give more options for access list:

private-passphrase: do not use passphrase from hotspot's user credentials, but given one - or unset (use default passphrase) with special word ignore
ssid-regexp: set a different SSID regular expression to match
vlan-id: connect device to specific VLAN
vlan-mode: set the VLAN mode for device

For a hotspot called example the template could look like this:

/ caps-man access-list add comment="hotspot-to-wpa template example" disabled=yes private-passphrase="ignore" ssid-regexp="^example\$" vlan-id=10 vlan-mode=use-tag;

The same settings are available in hotspot user's comment and take precedence over the template settings:

/ ip hotspot user add comment="private-passphrase=ignore, ssid-regexp=^example\\\$, vlan-id=10, vlan-mode=use-tag" name=user password=v3ry-s3cr3t;
