If you are having a problem with your network connection, always first check if the firmware of your WiFi router and your speaker is up-to-date and restart your router.
- Make sure you choose a unique network name. The network name or SSID (Service Set Identifier) identifies the WiFi network for users and other WiFi devices. The name is case-sensitive. If the SSID is not unique, WiFi devices will have problems identifying the network. This may prevent devices from connecting automatically to the network or cause them to connect to other networks that have the same SSID. This may also cause the WiFi devices to not use all the routers in your network or to not use all of a router’s available frequency bands.
- For the best performance, select the ‘Automatic’ mode for the channel selection and let the WiFi router choose the best channel. If your WiFi router does not support this mode, choose a channel that is not being used by other WiFi routers and other sources of interference.
- Hidden networks do not transmit their SSID via WiFi. This option is sometimes also (incorrectly) called a ‘closed network’, and the associated unhidden status is also called ‘broadcast’. Make sure this function is set to disabled Because hidden networks do not transmit their SSID, devices may need more time to find them. When a WiFi network is hidden, this does not mean that it is secured, because the SSID can also be ascertained in different ways. You must always enable security on your WiFi router.
- Make sure that restricted access to a WiFi router for devices with certain MAC (Media Access Control) addresses is set to disabled When this function is enabled, a user can configure a list with MAC addresses for the WiFi router in order to restrict access to only devices with an address that appears on the list. However, devices with MAC addresses that do not appear on the list will then not be able to connect to the WiFi network. MAC addresses can easily be changed. So do not assume that they prevent unauthorized access to the network.
- Make sure WMM is enabled. WMM (Wi-Fi Multimedia) priorities network traffic based on four access categories: voice, video, best effort and background. WMM must be enabled in the standard configuration for all 802.11n and 802.11ac access points. If WMM is disabled, problems may occur with the entire network. Multicast should always be enabled for multi-room audio setups.
What is the best channel width?
- 2.4 GHz channel width: The channel width determines the size of the ‘pipe’ that is available for transferring data. Wider channels are more sensitive to interference and are more likely to interfere with other devices. A 40 MHz channel is sometimes called a wide channel and a 20 MHz channel a narrow channel. Make sure you set the channel width to: 20 MHz Use of 20 MHz channels in the 2.4 GHz frequency band. Using 40 MHz channels in the 2.4 GHz frequency band can lead to problems in network performance and reliability, especially if other WiFi networks and other 2.4 GHz devices are close by. A 40 MHz channel can also cause interference and problems with other devices that use this band, such as Bluetooth devices, wireless phones and WiFi networks in the area. Routers that do not support 40 MHz channels in the 2.4 GHz frequency band do support 20 MHz channels.
- 5 GHz channel width: The channel width determines the size of the ‘pipe’ that is available for data transfer. Wider channels are more sensitive to interference and are more likely to interfere with other devices. Interference is less of a problem in the 5 GHz frequency band than in the 2.4 GHz frequency band. A 40 MHz channel is sometimes called a wide channel and a 20 MHz channel a narrow channel.
Preferable network settings for the 5 GHz network
For 802.11n access points, set the 5 GHz band to 20 MHz or 40 MHz.
For 802.11ac access points, set the 5 GHz band to 20 MHz, 40 MHz or 80 MHz. (80 MHz might cause some interference)
Enable support for all channel widths for the best performance and reliability. This will allow devices to use the largest width they support, resulting in optimal performance and reliability. Not all client devices support 40 MHz channels. You should therefore not enable only the 40 MHz mode. Devices that only support 20 MHz channels cannot connect to a WiFi router on which only the 40 MHz mode is enabled. You should also not enable only the 80 MHz mode, because in this case only clients with support for 802.11ac will be able to establish a connection. Routers that do not support 40 MHz or 80 MHz channels do support 20 MHz channels.
NOTE: Don't combine multiple routers and acces points in the same network if not necessary and it it's no to be advised to combine multiple brands for extenders/repeaters since this might caude compatibility issues. Also check the article regarding interference to see whether this might offer a solution.
