Hi Emmanuel, hi all,

Ok, here we go. First of all, it seems that the problem is solved
inthe sense that the connection stays alive all the time and does not
disappear. OTOH, I now get quite a lot of messages, that might point
either to a broken AP here, or something else:
After resume I see:

then it starts with these, and there are *many* of them, literally
several hundreds
[ 4019.340036] ieee80211 phy1: release an RX reorder frame due to timeout on earlier frames
Intersperesed I see some other messages that are new to me:

At the end there are mostly two lines, the
[ 5983.321525] net_ratelimit: 1 callbacks suppressed
[ 5983.321537] ieee80211 phy1: release an RX reorder frame due to timeout on earlier frames
Where for every 10-20 of the second one there is one of the first one.
=============================
Anyway, the connection might stumble now and then a bit, but it does
not break down, so I don't complain ;-)
BIG THANKS to everyone!!!
Best wishes
Norbert

not so much for effect as because he was trying to remember
the sequence of muscle movements.
