There are numerous sources of errors in a home network.

Often a home network grows piecemeal. Whenever a new network device is added - a computer, a WLAN access point, an IP camera or the new TV - the device is simply plugged into the nearest hub/switch or the router. If there are no more ports free, a new, smaller mini-switch is used to get a few more ports. In this way grown networks often involve problems.

Therefore, it makes sense to think about the purchase of larger and slightly more expensive switches.

These switches have the following advantages:

  1. The network is clearer, thanks to one "large" switch instead of many "small".
  2. The data flow is significantly improved by a professional switch. Because data packets are only sent to the network devices, for which the data are intended.
  3. Especially for multicast data packets (one source - many receivers), which are also used for group playback of music, professional switches are advantageous. They support the IGMP protocol, which significantly reduces the network load and thereby relieving the network devices.
  4. Managed switches have a web interface with which it can be configured and therefore can be optimally adjusted.

This article describes how a managed switch is established. 
The article describes the configuration of the switches HP 1920G, HP E2620-24-PoEP and Cisco SG300-10, that we like to use. There are numerous other, similar switches. It is not possible to name them all.
