Hi, I've got WRAP boards with Wistron CM9 miniPCI cards. Software - kernel
2.6.15, madwifi svn1705. Link is 3.2km long and signal level is reported
to be around -65 dBm. The performance is satisfactory - the link can do
4-5Mb/s symmetrically (when it works). However I can see that client
reports lots of beacon misses - today it's 230 within 6 hours. According
to the source (net80211/ieee80211_proto.c) the client reassociates
everytime it misses beacon. Is this behaviour mandatory? Does it REALLY
have to reassociate every time? This behaviour makes the line almost
unusable, because the client reassociates every 90 seconds. Or is there
any way how to decrease the number of beacon misses?
It doesn't matter if I run encryption or not, it behaves like this
everytime. I've tried changing ACK and other timeouts and no success
(well, I didn't expect them to help anyway).
Only thing which can possibly be of any help is using ad-hoc mode however
I doubt that this mode is stable enough - I got several WRAP reboots when
operation in ad-hoc mode (sorry, no debug here). However I NEED encryption
and I was unable to set neither WEP or WPA in ad-hoc mode.
Here's output of athstats:
