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 and matcher comment to your wpa interfaces' dhcp server. You can add more information to the comment, separated by comma. In this example the server is called hotspot-to-wpa.

/ip/dhcp-server/set lease-script=lease-script comment="hotspot-to-wpa=wpa" hotspot-to-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 comment="Test User 1" name=user1 password=v3ry;
/ip/hotspot/user/add comment="Test User 2" name=user2 password=s3cr3t;

This also works with authentication via radius, but is limited then: Additional information is not available, including the password.

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

action: set to reject to ignore logins on that hotspot
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;
