Hi,
We have two C25 controllers and I upgraded both from firmware 10.01.02.0038-1 to firmware 10.01.05.0008-1.
The upgrade went just fine, no problems with that.
After a while, the AP's also started to upgrade their firmware and then the problems started.
Some laptops lost the connection with the network.
After a reboot or reconnect in windows (drop connection and reconnect), the connection is back for a few seconds (3 - 30 seconds) and then it drops again.
I updated the drivers and firmware for the nic's on the laptops but it stays the same.
Problem seems to be with intel nic's but there are some laptops which are identical who don't have the problem so it's not clear what the problem is, but it started after upgrading the wifi controllers and AP's and this is URGENT !!!!!!!!!!!!!!!!!!!!
Since the problems started when the firmware was upgraded on the AP's, I think that is where the problem is.
So I started a case yesterday, until today no feedback at all...
Performed a firmware downgrade and problems are gone.
Thanks for the buggy update! our boss is very happy !!!!
