I have a sub I got second hand. I'm able to start the process of adding it to my system, but before I can add it, the app insists on updating the device. Every single attempt at updating the device has failed. I get no error codes to work with, and the device is just flashing red.

So far I've tried:

• Updating my system as a whole

• Reinstalling the app

• Restarting the device and my router.

• Plugging in the sub with an ethernet cable (both before the update and mid update)

• Splitting my network into separate SSIDs for 2.4Ghz and 5Ghz

• Assigning a static IP to the sub

I've been on the phone multiple times now with Sonos support and still have not found a solution. They've transferred me up to level 2 support but they have no openings in the next few months for a call.

Has any one on here run into a similar issue?

Does anyone have any other ideas for things I could try?
