The bandwidth provided by your ISP (Internet Service Provider) is advertised as ‘up to’ as this is the maximum bandwidth you can expect coming into your network. This can be affected by many things such as the quality of the provider’s cabling, ‘Fair Use’ clauses in the agreement and the amount of people accessing the same server. But even if you get the maximum advertised bandwidth from your ISP, the home network may be creating a bottleneck.
This is a basic step for any electronic device, as updated firmware may address known bugs. 2. Reboot the router. Routers are basically computers and are affected by the same problems. Bugs and temporary errors can cause too much memory being used, or the router can be overheating (one reason to not place it in an enclosed space!). In addition, there may be IP address conflicts. Rebooting the router will often help with these issues.
Wi-Fi signal is like sound – the further you move away from it, the ‘quieter’ it is – the less bandwidth is available. 5. Move transmitting devices away from the speakers. Transmitting devices such as cordless phones, Bluetooth devices, baby monitors and even routers can cause interference if too close. You can troubleshoot by turning off nearby transmitters and seeing if this improves the network performance of the KEF speaker system. If it does, try increasing the distance between the devices.
A note on 5 GHz channels – not all channels are open for public use in various countries. Check with your local authority as to which channels are unrestricted (most routers will automatically turn these off if the router is correctly configured for the country). Table of Contents often set to ‘auto,’ but some routers are better at swapping channels than others, so it can be useful to set the channel manually.
