I just upgraded my router's firmware to make sure it was up to date to add a Mesh extender, and now I cannot access my USB drive from my Mac that I have connected to the router. It worked perfectly before the update, and now I am getting messages that the network may not exist. In my control panel, the Neighborhood Newtwork option is selected, but there is no port assignmet like it used to have. It does register the USB drive that i have connected (My Book 750 GB), but I cannot access the drive from either of our Macs.

I should note, I recently updated to OS Monterey on my Mac as well, and my wife's is still running Catalina. She could access it as well before the TP-Link update to the router, but also can no longer access it. So I do not believe it has to do with the OS update on my device.

Anyone have any ideas as to what is going on? Thanks in advance.
