Im seeing this way to many places for it to be a client side issue...
I have quite a few APs that serve wifi customers at hotels....We are seeing many times where someone will continously keep trying to reconnect over a period of serval hours..
all we see in the logs is:
Extensive data loss..
and then a connection 3-10 seconds later...
and extensive data loss again.
SOme of these are on APs where the client has a -70 to -85 signal...anything less i write off as true extensive data loss
We mostly have 8602 radios, but have seen this on cm9's we have too...MT versions on all APs is greater than 2.9.25
any ideas? or anyone else seeing this?
