[Aironet] can't connect two aironet BR340

[Jens K. <jk...@gm...>]

Hi
have two aironet BR340 (why does the telnet client tell me Aironet BR500E
V8.24 ?), on top of two buildings, 400m between them.
We have tested up to 20m, which worked fine, but now with 400m it's not
working.

Does anyone here have some experience with that ?
Maybe this is not the correct list, but i didn't find a better one :(
Tnx a lot, jens
