If connected wirelessly:
Basic
Steps to take if using a wireless connection. These steps do not involve changing the
settings of your router:
1. Ensure the router firmware is updated.
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 help with all these issues and
should be performed periodically (every 2 months or whenever the network seems
considerably slower than normal).
3. Try connecting with an Ethernet cable to your router.
This may not always be possible, but if it is, going cabled will eliminate the issues
described below.
4. Reduce distance between the router and device.
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.
6. Reduce obstructions between the router and device.
And just like with distance, obstructions can block signal, reducing bandwidth.
Metal is the worst offender (reinforced concrete, back of mirrors), followed by
concrete, plaster and brick. This is one of the big reasons to get the router out of the
basement, or the cupboard under the stairs.
7. If your router is in a different room, try switching to the 2.4 GHz band.
Most modern routers are dual band. This means they transmit on both the 2.4 GHz
band and the 5 GHz bands. The 5 GHz band has higher potential bandwidth, but far
shorter range and is highly affected by obstructions. It may be possible that, whilst the
2.4 GHz band has a lower total bandwidth, in practice it is a better choice when the
router and speakers are not in the same room.
