I have a big problem into a building here, with the WiFi.
Actually users complain about speed of APs, so what I already did :
- Did a complet site survey with Ekahau Site Survey - Move/remove a lot of APs for remove Overlapping and get a good strengh of signal - Remove the 2.4 Ghz, like that users can connect only with 5 Ghz.
Unfortunetly, the last step was a disaster... users complain more than before.
Specialy some girls who are on a specific room. When I see the information of the concerned AP, OMM it's not normal at all.
The estimated Capacity is very low and I dont know what's wrong and how I can solve the problem.
OK I would suggest you go back to basics on this one. Cut the channel width back to 20MHz from the default 80 and then scan the unii 1 channels for availability and manually assign this channel on this AP and then test again. If the client devices near the AP don't support channel 112 then they won't hear the AP and will connect to another with most likey low quality signal in the area they are based.
Could you also advise what version of software you are running on the controller.
Go to the location where the particular AP services and do another passive survey with Ekahau. Check the AP's auidiable in this area and see if any AP in the UNII 1 range (Ch 36-48) can be heard at a level greater than -85dbm. if not then set your AP to which ever of these channels is free in that area.
