At my job I work with a mix of old and new wireless equipment. Some of the old stuff, such as Ubiquiti Nanostation2s, may not automatically let you ssh into them from newer workstations due these old devices using old / weak / outdated encryption algorithms, which newer operating systems tend to disable by default. If you’ve run into this, you’ll probably see a message along these lines:

Keeping wireless networks running smoothly can be a challenge, especially when you’re working with unlicensed frequencies and support hundreds or thousands of wireless connections. A tactic used by WISPs and other wireless network operators is to change frequencies on noise-affected devices, and changing frequencies may very well smooth out problematic connections. However, there is always the potential for unintended negative consequences, and this is what this post is about: being able to identify problems that arise due to frequency changes.
