A lot of probe requests

[FCervini]

Hi all,

We have R310 AP's with a Zonedirector 1200. Recently we started noticing short break ups in the Wifi connectivity many times a day. When looking at the log of an AP I can see a lot of the following lines:

Feb 7 20:16:31 RAP11 user.warn kernel: ieee80211_send_probereq: chan=11, v54_ie2_size=15

They are usual preced by user.debug kernel: Neighbour found.

and end a bit later with

user.debug kernel: Route found: xmitdev=br0

As you can see, they are grouped together on the same time (2 groups in this example). I am wondering if this has anything to do with the signal breaking up, and if it is, how it can be fixed? I can't seem the find much documentation on this.

Can anyone help me figuring this one out?

Thanks
