Strang problem, network devices somtimes not accacebel

[arnoldg]

hello,

i have rolled out a wifi network on oure camping.
but since a couple of weeks i have some strange problems.

the network accecs point and the pfsense machine are somtimes not accecebel in these cases i even can't surf the internet.
how can i find where the problem is.

i use a rather old version of pfsense. Updating pfsense is a no go, this is because i have a low internet bandwith 4Mb down 1Mb up
when i update i lose almost all my bandwith. i opend a discusion earlyer and there i get the advice to keep running this version.

i run this setup now for 3 years and almost without any problems.

please need some advice on how to discover this strange problem.

my setup is :

pfsense
2.1-RELEASE (amd64)
built on Wed Sep 11 18:17:48 EDT 2013
FreeBSD 8.3-RELEASE-p11

a switch at the computer
1 ap is  connected to the switch
1 switch is connected to the above switch
at this switch there is
1 ap
1 ap in bridge mode

at the otherend is also a ap in bridge mode
1 switch and 2 ap's

so i hope some could help me with this, maybe some kind of logging on the netork devices ??

i'm a little bit further, after giving my laptop a static IP.
in most cases all AP are acceceble but not pfsense.

there is one thing when i ping them there is sometimes a timout and most of the time the ping time is at 250 ms
