Hey again,
Ok- so I have tested this code with 2x IAP-215's for an hour or so, and my advice to you is DO NOT TRY IT. It is absolutely crammed full of bugs- things I have noticed:
1. Meshing "works" as expected... which is good...
2. With only 1x AP in the network (which assumes mesh portal mode)- so not even using mesh functions- so many things do not work (these things also do not work with meshing APs in play of course!)
a) Lync cannot establish connectivity to Office365
b) Many websites fail to load (similar to the behaviour experienced with a path MTU issue)
c) Wireless medium is very unreliable- intermittent packet loss and throuput issues even reaching the local gateway router (client <-wifi-> AP <-1gbase-t-> router)
Not a good experience. I wouldn't bother yet as it's so buggy...
