NOTE: For a client to roam seamlessly, the client must support 802.11k and 802.11v. For clients that lack 802.11k, a node will not be able to determine where to steer a client or even if a client needs steering. The clients lacking 802.11v, on the other hand, can’t be directed to change to another node.
If you know that your device supports 802.11k/v and you have exhausted all other standard WiFi troubleshooting techniques, you can then try to isolate the issue by turning OFF the Client Steering or Node Steering feature as the last resort.
For example, if some clients are connected to the 2.4 GHz instead of the 5 GHz, try turning the device OFF/ON first. If the issue continues, isolate it by turning OFF Client Steering to check if this fixes the issue.
If a device is connected to the farthest node, try power cycling that node. If the issue continues, then try turning OFF Node Steering to isolate the issue.
NOTE: Disabling the Node Steering option will not affect a mesh network. This will only stop the primary node from sending suggesting connection changes to the secondary nodes.
Dynamic Frequency Selection (DFS)
Some routers support Dynamic Frequency Selection (DFS). The DFS option may be enabled by default or disabled depending on the model and region. If you have DFS enabled, you can disable DFS if you have clients that do not support DFS channels and are unable to connect to the 5 GHz band.
This feature may appear on certain models such as the Linksys MX4200 but this feature is only supported for PCCW IPTV subscribers. If you are a PCCW IPTV subscriber, you can enable this feature.
NOTE: When you enable this feature, the default IP address of the router changes to 192.168.10.1. If you ever need to access the LinksysSmartWiFi.com page again, make sure to use the new IP address.
