System software download started but will not complete
If a system update began dowloading but got stuck or did not finish, try the following:
Check to see if other devices on your network are using too much bandwidth.
When a device is active on your network, they use some of the available bandwidt of your router. Some tasks use more bandwidth than others—like video streaming, gaming, video calls, data backups, etc. If devices are performing these tasks, bandwidth can decrease for other devices. Turn off any device or app that might be using a lot of bandwidth, then check if performance improves. (Tip: If available, use an Ethernet cable instead of Wi-Fi to connect high-bandwidth devices to your network. This frees up wireless bandwidth for devices that need to be connected wirelessly.)
Be sure the SoundTouch adapter connected to your product is within range of your router.
If your product is wirelessly connected to your router, be sure it is in an area with good Wi-Fi signal.
Check for sources of wireless interference.
It's possible that interference from other wireless devices are affecting the wireless functionality of your product. Check for other wireless devices in the area of your product (i.e. another router, cordless phone, wireless printer, smart TV, etc.). To determine if a device might be interfering, try unplugging its power cord or disabling Wi-Fi on the device. If the issue is resolved when a particular device is removed, try placing that device farther away from your product, if possible. Additionally, if the device has a wireless channel setting, try a different channel.
Reboot your router.
Routers may need to be reset from time to time—much like rebooting a computer. Disconnect power from the router for 30 seconds, then wait for it to start up and connect. (Note: Any device connected to the Internet will be interrupted during the reset.)
Try updating your product using the different available alternate update method.
If a particular update for your product isn't installing as expected, there are alternate ways to install it. Try the different update methods to find that one works. For more info, see Updating the software or firmware of your product
Try plugging in your product to the router using an Ethernet cable.
If your product works while using a wired network connection, the issue is related to the wireless network configuration. If you don't need to use a wireless connection, you can use a wired connection. For more info, see Setting up your product
