Specifically: HTTP/HTTPS (JavaScript?) content?
I just spent the last ±10 hours tearing-out what little remaining hair I have.
Scenario: Pepwave MAX BR1 Pro 5G, v8.2.0 firmware, multiple EnGenius WiFi bridges and APs, using the MAX’s LAN ports (WAN re-configured to add’l LAN port).
Problem: EnGenius WiFi devices’ config pages loading erratically or not at all. Didn’t happen with the laptop connected directly to the EnGenius devices (w/manually configured IP address on the laptop). Didn’t happen with the same devices plugged into our home network.
Had thought maybe it was a weird browser bug. Probably JavaScript-related. Had been using the Brave browser. Tried Firefox. Problem at first appeared to go away. “Ah HAH! Brave is b0rk3d!” Sadly: Not a chance. But, with lots of clearing the browser’s data, killing it, restarting it, reloading config pages, repeatedly, and a lot of patience: I could get things done.
But this was not a tenable situation.
Then, finally, the penny dropped: “The MAX…???”
Hauled out a spare switch. Moved everything from the MAX to the switch and plugged the switch into the MAX.
Problem solved.
I don’t know what the MAX is doing to cause this, but, whatever it is, it needs to stop doing it.
