Band Isolation
Hello,
Took me a while to figure this out so thought about sharing it.
Starting point : my printer would disappear from my network after a few seconds after power on.
I first blamed the latest firmware of the printer but it worked fine for a friend with Google APs.
I then blamed the OS but again, not only the same friend did not experience similar issues, but I was having the same problems on 4 different machines at home : the printer would always disappear.
The I noticed that my amplifier was not available anymore and I coulnd not use Spotifiy Connect.
The problem had to be the router. After spending one afternoon playing around, I realised that If I do not enable Smart Connect and set different SSIDs for the 2.4 and 5.0GHz bands, problems start occuring between devices connected to the 2.4 band and devices on the 5.0GHz band as well as devices physically connected to the LAN (i.e. ethernet). As if the 2.4GHz connected devices were isolated from the rest ?!
