Re: OT: Wireless Signal Strength

Assalamualaikum,

If this is problem with all AP's, then its highly unlikely that all
AP's have started having HW problem at once. I would suspect most
likely there is some interference problem, check if something has been
changed/added in the building?
I would recommend installing a standalone AP (not registering with
WLC) and connect to that AP to eliminate WLC's are not causing the
issue. If cleint clnnecting to that AP does not suffer similar signal
strength issue, then check whats been changed in WLC?

Wassalam,
