WiFi Band Steering is a feature in routers that assigns devices to the appropriate WiFi band. The two main WiFi frequency bands are 2.4 GHz and 5 GHz. This technology helps maintain the performance of a WiFi network by automatically selecting the best available frequency channel. In most cases, 2.4 GHz clients are unsuitable for 5GHz, so band steering helps you avoid these problems. However, it may not be right for you.
Generally, dual-band networks with Band Steering use the same SSID for both channels. However, if your network is large and has high client device density, Band Steering may not be enough to alleviate network congestion. It also depends on the manufacturer of your WiFi access points. You should check the specifications of the access point you plan to buy to find out if it supports the feature. If you don’t want to deal with network congestion, you should use a WiFi router without this feature.
In dual-band networks with Band Steering, you should use the same SSID settings for both 2.4GHz and 5GHz channels. This will prevent network congestion, but you may need more WiFi points if you have a high client device density. Additionally, Band Steering can’t solve network congestion, as it only works if your WiFi network has many simultaneous users. You should check the spec sheet of your access points to make sure they support this feature.
If you want to use 5GHz for your dual-band networks, you should ensure that your access points support Band Steering. If your devices have dual-band capability, you should set the SSID for both 2.4GHz and 5GHz channels. If your network is dense, Band Steering can’t solve this problem, and it may cause more network congestion. You should always check the specification of your desired WiFi access points for this feature.
