Very slow speed orbi satellite

I had the same problem recently, and after troubleshooting, realized that only 1 of my 2 satellites had updated the firmware on the last auto update.  However, in the admin page, it showed that no new firmware update was available for either my satellites or the router...even though it showed different versions installed.

I had to update the firmware manually on the 1 satellite and my speed returned, which I did successfully; however, it did require me to change my router admin password first, because the satellite wasn't recognizing my current router admin password.

Once I reset the password on the router, I was then able to log into the satellite and do a manual firmware upgrade.

Hope that helps.
