Description Kristoffer Grundström 2017-10-05 04:16:50 CEST

Description of problem: I have discovered an issue with my WiFi connection using a brand new router from ASUS and and a fresh installation of Mageia 6 made with the DVD iso. I'm using a ASUS N550JK laptop. Kernel that I'm using is 4.9.50-desktop-1.mga6. I have to add that I don't experience this problem in Cauldron even though Cauldron is supposed to be unstable.

How reproducible: I haven't rebooted many times since discovering this problem.

Steps to Reproduce:
1. Download the x86_64 DVD iso of Mageia 6 and install.
2. Choose MATE, GNOME, Cinnamon as Desktop Environments.
3. Make sure that you're updated.
4. Connect to a WiFi connection with the Wireless network card.
5. The connection works just fine until you either reboot or wait a long time.
It will go down and then within 5 seconds go up again.

iwlwifi is the module I'm using.

What do you mean with "wait a long time"? Wait while using the laptop and its wlan interface, or wait without doing anything with it?

If the latter, then what do you mean with "within 5 seconds go up again"? Within 5 seconds after it stopped working, regardless of whether you touch it or not, or within 5 seconds after you touch it?

Waiting while using the laptop and its wlan interface.

To me it looks like the Network interface breaks due to high usage.

I use git and repo sync a lot and if I sync from github I get that problem, but not otherwise.

After it goes down it comes back up again (reconnects) within 10 seconds.

No error is displayed other than that the wlan interface is down and up after some time.

Thx for having answered my questions.

Please create log.txt from just before till just after that happens, anyway :-)

  As root run (use the correct day+times):

   journalctl --since="YYYY-MM-DD hh:mm" --until="YYYY-MM-DD hh:mm" > log.txt

And then attach log.txt

It was to big to add as an attachment here.

You may also want to post your dmesg as well just:

dmesg > dmesg-$(date +%F).log

and then attach the log.

It could be the router as well, but it's brand new and I flashed it with the latest firmware available.

I'll flash LEDE/OpenWrt to it to see if the problem goes away.

I'm lazy enough to wait till you report back (so I'm not yet reading your attachments) ;-)

Comment 12 Kristoffer Grundström 2017-10-13 00:50:42 CEST

Flashing the router with LEDE/OpenWrt seems to do the trick. Fawlty original firmware I guess.

Comment 13 Kristoffer Grundström 2017-10-13 00:52:24 CEST

Closing as RESOLVED WORKSFORME as the issue was in the router and not in Mageia itself.

If I made a boo boo because you experience the same issue, please go ahead and reopen it with new information.

Resolution: (none) => WORKSFORME
Status: NEW => RESOLVED
