Hi Meenakshi,

thanks for your email

Yes, let us make another trial ;-)

You'll see this message if you have debugging enabled for mac80211, specifically CONFIG_MAC80211_HT_DEBUG. Perhaps you could reduce the debugging information you print out for mac80211?

Probably I was asked to activate that at some point ;-) Will disactivate
it. Thanks.

I will do when I am back at university.

On the university often no connection at all.
At home: connection hangs for several seconds, when I look at the
ping I have more than 20% packet loss. And interestingly
quite often the ping looks like:
64 bytes from ( icmp_req=131 ttl=53 time=125 ms
64 bytes from ( icmp_req=133 ttl=53 time=124 ms
64 bytes from icmp_req=134 ttl=53 time=135 ms
64 bytes from ( icmp_req=135 ttl=53 time=123 ms
64 bytes from ( icmp_req=136 ttl=53 time=121 ms
which does NOT relate in anyway to my feeling, because when I
check the *real* time *before* the line
64 bytes from icmp_req=134 ttl=53 time=135 ms
there are *several* seconds, (3-4, sometimes more) of waiting time.

That of course destroys regularly every ssh and ftp connection.
http is of course not the problem (but who cares for the web?).

I have create a log with the above debug settings but 11n NOT disabled.
I also added some
===== remarks =======
(variable number of =, tough, but at least always 4, so you can search
for ====) with logger "....". The log is *BIG*, compressed 3Mb, you
can find it here:

Ok, when I have something from the university I will let you know.

Best wishes
