Disabling Background Scanning in Client Mode

In a dedicated link topology where you never want your client to roam to a different access point, you will want to disable client background scanning. In a bridged backhaul topology it was found that this significantly increased total throughput and possibly stability. Basically, by default madwifi clients will stop passing traffic temporarily to do a background scan of available access points. So this is unnecessary and undesirable in a dedicated link topology.

The results of disabling this functionality were extremely positive in allowing better bi-directional and single direction throughputs.
