mikrotik all the AP of my network uses wds with rstp. and all the users
of my network they have his AP client with the IP of edimax default
192.168.2.1.

the rare thing of all this has been the following thing (for months this walking of
this way up to 1 week back)… I have clients connected with very
good signal of the side of the client and my AP mikrotik… but does not have
pins between my AP and the PC client… when sights the status of edimax
it appears to me connected.
it passes in a single east tower problem to me. my AP is
532 with 14db and 200 a panel mw senao 2511. above I have one omni
hyperlink 15 with one xr2 also to he himself rb. I associate it to omni and
it follows with he himself problem. changes , antenna, minipci, pigtail .etc
before xr tapeworm ampli with 1watt thought that the problem venia
from the side of the noise, it removes ampli and I put xr to omni but
problem persists,
