Okay, I've simplified this a bit. I've got 2 identical switches (Linksys
SFE2000), and they stack just fine with a regular cable. As soon as I put
the switches on either side of the Ubiquiti Nanobridge M5, I cannot get them
to see each other. And these things should stack automatically, it's not
rocket science here. I've definitely narrowed it to an issue with the
bridge itself. Could there be something like an MTU that I need to set on
the switches, to shrink the packets? Are they sending packets that are too
large for the Nanobridge? Any ideas/suggestions? This is getting
aggravating, surely these things are made for doing stuff like this. I've
also got a call in with their tech support, one of these days I might hear
from them. :(
