Description Timo Riikonen 2016-01-21 06:59:03 EST
+++ This bug was initially created as a clone of Bug #1087717 +++

Description of problem:

When I use WPA2-AES secured 802.11n Wifi, connection breaks up sometimes so often that internet is in practice unusable. Sometimes not that often, but the speed is still always terrible.

It seems to me that this would be an old bug that has resurfaced again. I would be happy to this if this is correct or not, but I need instructions on how to do that.

I am using HP Envy with Intel 7260 WiFi adapter on latest Fedora release.
kernel.x86_64                  4.3.3-301.fc23 

sudo dnf list iwl7260-firmware
Installed Packages
iwl7260-firmware.noarch              1:               @updates

How reproducible:

According to previous defect texts version is working well, but this command doesn't work: sudo dnf -y downgrade iwl7260-firmware:
How can I downgrade the version?

See comments from bug 1087717 on how this was fixed the previous time.

Comment 5 Emmanuel Grumbach 2016-01-23 23:10:36 EST
Can you please try to update to -16.ucode?

You can find it here.  https://git.kernel.org/cgit/linux/kernel/git/iwlwifi/linux-firmware.git/plain/iwlwifi-7260-16.ucode
Comment 6 Timo Riikonen 2016-01-24 08:06:01 EST
-16.code file has been copied to /usr/lib/firmware and OS has been rebooted. As it is the latest version I presume it is therefore in use.

This is new laptop. For couple of the first days even fetching google web page was sometimes too much load for the WiFi. But after that the ADSL/Wifi has been in less use and it can now takes hours in between clear Wifi errors.

I tried to find test & analysis tools but without success, so I suppose I need to test this second most recent version (17 was there as well).
Comment 7 Emmanuel Grumbach 2016-01-26 16:05:16 EST
Does it feel better with -16.ucode?
Comment 8 Timo Riikonen 2016-01-27 04:21:54 EST
No, it is still the same: works sometimes with varying quality.
Comment 9 Emmanuel Grumbach 2016-01-27 04:28:32 EST
Can you record tracing?

I found plenty of complaints on the WiFi router. We replaced that with another decide from a different manufacturer and this fixed the compatibility issues.
