ST-10 no longer connects to wireless after 17.0.8 upgrade
Hi. I have a Soundtouch network with 3 ST-10, 1 ST-20 and 1 SA-5 speakers. Things were working well until I upgraded all the speakers to 17.0.8 yesterday. Now my 3 ST-10 units can't seem to connect to my wifi network anymore. The ST-20 and SA-5 are working fine, but they're connected via ethernet so I'm not sure that's a fair test. Here's what I've tried so far:
1. Powered everything off (including the router) for 30+ seconds and then powered up each device one a time.
2. Held down Vol - and 2 to put the speaker into initial wireless mode, then connected to the "Bose <mac>" wifi network and re-entered wifi settings
3. Held down Vol - and 1 to reset the speaker to factory defaults and then attempt to reconfigure from scratch
In all cases the speaker sees my home network, but fails to connect either with "connection timed out" or "connection failed please re-enter key".
Here are the specs for my wireless nework:
Router: Asus RT-AC68U
Authentication Method: WPA2-Personal
WPA Encryption: AES
WPA-PSK key: [18-character passphrase]
All Bose Speakers are running Software Version 17.0.8. I'm using iOS App version 15.120.23 to control the speakers.
Interestingly, if I leave one of the ST-10 speakers alone for a while it will sometimes successfully connect to the wifi network. However, the connection doesn't last long and the wifi status light goes back to blinking white.
I'll re-emphasize that the ONLY thing that changed was upgrading the speakers to 17.0.8. I also have lots of other devices connected to the wireless network that are still working fine.
What additional information can I provide to assist with troubleshooting? Alternatively, is there a way I can downgrade the ST-10 speakers to a previous software version? Any help you can provide is greatly appreciated!
