What are the disadvantages to enabling mesh?

I understand that the upstream access points will have to handle the load from any mesh-connected APs, but is this the only disadvantage?

You can't use the 5Ghz band for the device, because it's used for the mesh link (if my remembers are good)

This is a common misconception and is in fact incorrect.  I just wanted to clarify this in case someone is searching for info.  Even if the AP is using Mesh as its uplink, you can still use the same radio for client access.

Believe it halves the theoretical bandwidth. A reason to avoid having it enabled unless you really need it. A wired AP can theoretcially provide a possible 300Mbs to it's clients whereas a meshed one only 150Mbs (please correct me if I'm wrong someone)!

Reduces WLANs per WLAN group from 8 to 6.
Reduces max possible VLANS from 256 to 192

To remove Mesh also requires ZD reset to default, in other words back to square one.
Problematic if you thought it was a good idea to enable it but didn't really need it. You can disable it on the APs but it will always remain enabled on the ZD until a default reset.

So think before you apply..

Thank you guys for replying.

I'll be giving it some thought before I activate it.
