Performance Testing in 2.4 GHz and 5 GHz

I’m duplicating this comment in to topics I created where it might be appropriate:

Thinking about this, it occurs to me that disabling and re-enabling Wi-Fi on the surveying Mac would probably cause it to re-associate using the best-performing AP, and would further cause the Mac to re-associate using the best-performing connection. This at least would help with the problem I experienced where my machine dropped a 5 GHz connection and never re-established it.

I would be interested in whether it might be possible to have an option in which NetSpot kills and then re-establishes the Wi-Fi in order to ensure that the Mac performing the survey is connected to the closest AP and connected at the best possible speed.

Note, this also does seem like an incredibly hackish way around this issue.

Fair enough, but if I’m cursed with a set of bad options (which I’m assuming I am because I gather that testing leverages the existing Wi-Fi connection), I would personally be happier to get iPerf readings off the most powerful AP, rather than unknowingly continue to get my iPerf readings off a sticky AP that’s halfway across the facility because Apple’s software isn’t triggering an association to something with a better quality connection.

The issue is that it seems like all of the available choices have some significant downsides, but the issue of sticky client failing to roam to a more powerful AP is likely to give us bad results in iPerf testing. :-(
