disconnected, received disassoc:sending station leaving (8)

This has really been a problem when I am trying to use the internet without interuption or dissconnection. Im not sure why it does this But it happenes with laptops, and desktops, I havent yet tried using a CPE unit such as a airbridge radio or proxim.. I will give them a try tonight to see if it still does it or not, but with 3 different laptops and 1 desktop it does this every 9 minutes, Is there anything i can do to fix this problem? and is this problem even on the AP side? All of the signals are perfect aswell.

Here is what i have. RB133 with Sr2 connected to a 15 dbi omni antenna, using MMCX connection to N-Male pigtail. Using usermanager MAC authentication. Any help would be appreciated thanks! . -Jordan

What is “perfect” signal?

Do you have the SR2 powered back a bit? If you’re running at default you’re well above the legal limit.

A perfect signal would be standing 5 feet away from it with 43db, and it is set to default, and right now it is not out in the opent so im not frying anybodys mobile phones yet… I will be staying with legal limits, But as far as the laptops alwasy dissconnecting from it can anybody help me with that reason? Thanks -Jordan

Power is too high. Vertical beamwidth is too low. At the very least use a different antenna - 8dbi max

Have you tryed differnet channels?

Yes, dosent seem to change it much…


I will turn the power way down to like 10dbm, or less, I dont have another antenna handy right now so i cant try that, but i will give the power a try, and as far as vertiacal beamwidth is to low 8 feet away from the antenna LOS, mid way between the antenna.


How far will a 9 dbi distribute a signal? is 12 dbi a better antenna for distance and being on a 50 foot antenna? Just asking. -Jordan

More dbi is almost always better when it comes to distance. We use 12dbi antennas for all of our 2.4 APs and have multi-mile links with no problems (13dbi panes on client side) as long as you have LOS or a few trees at most. lower dbi antennas are better if you have many clients really close, but even with an antenna 155’ on one of our towers, we can still connect fine with a laptop at the bottom directly below. Can’t connect inside a building right below, but we just set all the clients up with antennas anyway which get the signal outside their house and overcome the “it’s too high” problem. If we wanted to, we could just add a 7dbi antenna at 50ish feet to fill in the “donut hole”.

A mi me salia lo mismo, resulta que el cliente habia cambiado la ip, lo puse en automático y se arregló todo.
