Square POS - how to turn off wireless mac address randomisation?

hosp123sq — Sun, 21 Sep 2025 07:12:46 GMT

We are setting up a Square POS and attempting to connect to a corporate wireless network. Our authentication system can only accept fixed wireless mac addresses and not randomised mac's/ private mac addressing. Is there any way to toggle this like on IOS/Android devices? I've seen some other posts that don't really provide a solution and hoping that there may be a more updated response given the product may have had some software updates since.

Thanks in advance!

Hi @hosp123sq,

Really great question!

For quick reference, if you're using a Square Terminal, please ensure your network is configured according to the following requirements:

Square’s MAC OUI: 44:59:25
Merchants should whitelist all MAC addresses that start with the above prefix (i.e. devices with MAC addresses following the pattern 44:59:25:XX:XX:XX). Alternatively, merchants can whitelist each individual device that shows up with that MAC address prefix (this prefix is owned by Square and should not be used by any other device vendors).

We recently identified an issue with Square Terminals connecting to networks with MAC filtering enabled, but this was resolved in software version 5.41.0085. It sounds like your issue may be related to the reports we received from Sellers running version 5.41.0084 on their devices. To ensure your Terminal is running the latest version, please navigate to More > Settings > Hardware > General > About Square Terminal > Software Update. If you see 'Software Up to Date', then you are all set.

If you're still unable to connect to your preferred network, a workaround would be to temporarily disable MAC filtering on your network or to connect the Terminal to an alternate Wi-Fi or Ethernet network (this method can also help establish a connection to check for and update your device software).

I'll also drop in the Square Terminal Troubleshooting Guide, which includes a few more details about network requirements.
