Pepwave Surf SOHO: how to change wireless client name ?

I have a Canon printer connected to the Pepwave Surf SOHO via wifi but its client name is shown as its MAC address. Is there any way to change this so that it displays the name of the Canon printer ?

Here’s an example from a Pepwave MAX router. I’m reasonably certain the procedure is the same for the SOHO.
Go to Client List and click on the Name of the device you want to change, in my example where “beach” is shown. You’ll then be given an opportunity to edit the name.
