Polk Omni S2 Won't Connect Over Wi-Fi

Make sure your router is up to date. If it is older, you might need to upgrade to a new router. Polk recommends an "802.11n" type router or better, but an "802.11g" router or better is required. Pay attention to the last letter, as all router types start with "802.11". Also note that router types aren't ordered alphabetically (802.11ac is better than 802.11n, for instance).

Make sure your speaker is in an area with a strong Wi-Fi signal. If you're setting up your speaker, try to set it up near your router.

Ensure other wireless devices like phones and computers aren't interfering with the signal by disconnecting devices that aren't in use from your network.

You can try resetting your speaker to factory settings by holding the Wi-Fi button down for 15 seconds. You will hear three sets of tones: the first two are for Wi-Fi setup, while the third and final set of tones indicates that the speaker is being reset. Once the speaker has been reset to factory default settings, try setting up again on your network.

Some users have reported that having special characters (<>^%, etc.) in your network name makes the network undetectable by the Polk App. If your network's name has special characters, try changing it to one with only letters and numbers, no special characters or spaces. For most routers, you can change your network's name using your router's administrator page or through your router's mobile app.

Users with a dual-band router (2.4GHz and 5GHz) will have two different networks: one for the 2.4GHz band, and one for the 5GHz band. Some users with these types of routers have reported that if these two networks have the same name, the speaker won't be detected by the Polk App. Try changing the names of the networks so that they are different (but don't use special characters, as noted above). For most routers, you can change your network's name using your router's administrator page or through your router's mobile app.

Users with a dual-band router (2.4GHz and 5GHz) will have two different networks: one for the 2.4GHz band, and one for the 5GHz band. For users with these types of networks, it is recommended to connect to the 2.4GHz band. If your speaker is connected to the 5GHz band, disconnect it and connect instead to the 2.4GHz band (make sure the two bands have different names, as noted above).
