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:
- Dual WAN, Dual Router and Dual Switch
- Dual WAN, Dual Router and Single Switch
- Dual WAN, Single Router and Single Switch
- 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.
