I have my bose speakers connected to an apple extreme router, which is hard wired to the hughes network satellite router.
Apple Extreme AP is a dual-band AP: 2.4 Ghz & 5.0 Ghz.
Left alone, Bose products will join 2.4 Ghz (even though 5.0 Ghz is available) due to bad algorythm in the wireless chip. Don't blame Bose for this: Bose specialize in audio products. And I'll leave it at that.
However, try this:
1. Create an SSID (WPA2 AES/PSK) that is only broadcasted in 5.0 Ghz.
2. Disable the following 5.0 Ghz Data Rates: 1- to 11 Mbps;
3. Configure the following Data Rates as MANDATORY: 12-, 18- and 24 Mbps; and
4. Mark the rest of the Data Rates as "Supported".
Give the above a whirl and let us know if there is/are any changes.
Did you have the same symptom before applying this solution?
My Soundtouch 30 would connect only to 2.4 Ghz even when I have 5.0 Ghz & the Soundtouch could be seen by 3 of my APs.
Do you know how to clear out the old SSID and password out of the bose?
Just do a factory-default and use the app to re-configure the appliance.
