How do I encourage clients to use 5 GHz over 2.4 GHz
AFAIK, this is enabled by default in InstantON,
Note: Radio setup isn t accessible,
This is done by default in the background by adaptive radio management. APs are constantly scanning the background and if they detect interference, then clients are automatically steered.
Instant On release 1.4 now has controls and knobs to make such changes. Do take a look once you upgrade!
