Massive Packet Loss on Pepwave Max Transit Duo

I’m suddenly experiencing significant packet loss on my Pepwave Max Transit Duo that I’ve been using daily for over a year.

The packet loss happens whether I’m using Speedfusion or not.

The packet loss only occurs when I’m connected to the Pepwave via Wifi. Happens on multiple client devices.

No (or minimal) packet loss when client device is connected via ethernet.

Thought it was a wifi issue, but ran the packet loss test between computer and Pepwave over wifi and seeing zero packet loss.

Now I’m at a loss for what the heck could be the cause of this. Any thoughts?
