How to Build a Resilient Home WiFi Network

The LAN architecture in your home has a major impact on the resiliency of your Wifi network connection. These requirement should drive your home network architecture to ensure stability and ease of use.

Resilient: Failure of a component results in zero to minimal downtime experienced by the user. A resilient LAN architecture would consist of dual home WiFi routers, dual switches and dual connectivity between the components. The design of a resilient architecture is driven by your need to remain functional in the event of a network failure of one of the components.

Non-Resilient: Failure of a component results in a downtime to the end user. The length of the downtime is equivalent to the time taken to repair the failed component. A non-resilient LAN architecture would consist of single switches and or single routers.

Resiliency requirement will be driven by each business. So, below are some of options can be used:

  1. Dual WAN, Dual Router and Dual Switch
  2. Dual WAN, Dual Router and Single Switch
  3. Dual WAN, Single Router and Single Switch
  4. Single WAN, Single Router and Single Switch

Configure your LAN devices with these settings for optimal uptime:

  • LAN client (end user) environments speed / duplex should be set for Auto/Auto on the switch port and LAN client NIC.
  • Printers, for all environments, speed / duplex should be set to Auto/Auto on the printer NIC and switch port.
  • All non-SOE clients and non-SOE printers; if auto negotiation support is verified, the client NIC and switch port should be set to Auto/Auto. If auto negotiation is not supported, the client
  • NIC and switch port should be hard coded to 100/Full.
  • File servers, speed / duplex should be hard coded to either 100/Full or 1000/Full on the switch port and file server NIC.
  • Network devices (switch to switch/ switch to router/ router to router/ firewalls, etc) must be hard coded to /Full. is whatever the required speed for both device interfaces.
