My broadband router has two wireless APs built into it:
One runs in the 2.4Gz band and provides 802.11 b/g/n (up to 144Mb/s) so is suitable for devices with older wifi capability.
The other run in the 5GHz band and provides 802.11 a/n/ac so is suitable for newer devices and runs up to 1300MB/s.
The problem I'm encountering is that my 5GHz device frequently autoconnects to the 2.4GHz AP, so I get degraded speed when that happens (I download a lot of raw data, so this matters).
Obviously I can manually reconnect to the faster AP but that's a pita, especially when it's reconnecting after a resume & connects to the "wrong" AP.
I have both types of device, so I need both APs, so I can't simply disable the "slow" AP in the router.
The MACs of both 2.4 & 5GHz APs are known, if that helps; And we can set the two APs to use different SSIDs (and WPA2 keys) if that also helps.
How can I configure my puppy wifi to restrict its connection to the "fast" AP?
