Will a Sonos Connect Zone Player 90 recognize 5G

Wireless routers come with a default IP address set for them. This is usually 192.168.1.1 but depends on the brand and can be changed. If you can find that address, use that as the location in your browser. You should be presented with a login screen for the configuration screens of the router. Hopefully your router has an admin password and it is written down somewhere (username is probably admin). If it doesn't have a password, you need to set one to prevent easy hacking. Once in the configuration you should be able to find the setting for changing the channel (check the manual).

Djohnson thanks for the advice that did it! Changed it from auto to channel 1 and for two solid days now no dropouts! Thanks again!

Terrific. Glad that was it. I think a lot of the issues that people have with dropouts and wireless routers are related to the channel. It's pretty silly that they all ship with the same setting.
