"No association and the time event is over already..."

[Blue Glacier]

Hello,

my Intel Wireless 7265 chip suddenly stopped working. The Network 
Manager shows that I am connected, but I cannot even ping to my home 
router. I didn't change anything on my system.

The output of dmesg looks interesting:

[  507.737606] wlan0: Connection to AP c0:25:06:ce:d2:e9 lost

(repeated numerous times)

I am using Debian 8 Jessie (stable) together with the firmware from your 
server (iwlwifi-7265-9.ucode). The Kernel Version is 3.16.0-4-amd64.

Any idea how to fix this?

What is your AP? Can you reproduce consistently? If you disable WiFi
and re-enable WiFi from the Network Manager, does it help?

Can you try a more recent kernel with a more recent firmware?
You can check https://wireless.wiki.kernel.org/en/users/drivers/iwlwifi/core_release
if you want to update your driver without changing your kernel.

Hello,

yes, already tried to disable and re-enable WiFi. Didn't help.

I guess AP means Access Point. It is a "FRITZ!Box 6360 Cable (um)". I 
tried to reboot it. 15 minutes later it suddenly worked - but only for 
two hours. Now the connection is broken again.

While ping times out, I sometimes seem to be able to load websites - but 
it takes almost 10 minutes and many elements are missing. I am also 
repeatedly asked for my WiFi-password, which worked until yesterday.

I compared the md5 hash sums of the driver image (iwlwifi-7265-9.ucode) 
that I have installed and the one that is available through the link you 
gave me, and the sums are equal. Therefore, I think it doesn't make 
sense to try the other image.

I don't know if it is a good idea to install a different kernel on 
Debian Stable.

This seems to point to an AP problem... We've had lots of issues with
the FRITZ!Box Access Points. Would you be able to take a sniffer
capture of its beacon in the bad and good case?

As a debug step, you can try to disable power save:
iw wlan0 set power_save off

-9.ucode is fairly old and we won't release any new version of it. I
recommend you install the backport version of the driver and try
-13.ucode. To install a  coherent version of the driver / firmware
combo, please check
https://wireless.wiki.kernel.org/en/users/drivers/iwlwifi/core_release.

Since it might confuse you, let me explain the release model of the
firmware. The X in -X.ucode is the major version of the firmware which
usually includes new features etc... Without changing the X, we
sometimes release new versions with bug fixes. So you seem to have the
latest version of the -9.ucode, but that firmware is missing lots of
bug fixes that won't be backported.

Right - this is why I suggested the backport solution.
