Periodic WiFi connection issues that resolve after reconnecting

Support Network
1

I installed Manjaro w/ KDE recently and my WiFi has been acting strange since installation. Despite staying connected, it periodically stops working until I disconnect and reconnect.

Network manager says “limited connectivity”, DNS resolving fails (pinging fails and matray pops up with a “Temporary failure in name resolution” in manjaro.moson.eu), and no webpages load. Discord can sometimes receive messages but can’t send them. However, existing connections to game servers (i.e. Minecraft) continue to work fine.

I have an Intel AC-8265. My issue appears related to another post (I can’t post links though), so I tried installing iwlwifi-next and changing the .conf files, but this only made the issue less frequent. The issue wasn’t resolved for that user either, and there wasn’t any more replies. I also tried updating to the latest kernel, 5.16r6.

Interestingly, a similar issue was present (less frequently) on Windows; no DNS resolving or sending Discord messages until reconnecting. Perhaps it’s a driver issue present in both OSes, or maybe an issue with my hardware?

I’ve found bug reports of similar issues in iwlwifi since at least kernel version 5.1.0 :confused:

Are you running zen kernel?

No, “zen” is my device name

I have seen similar issues with Cloudflare’s DNS servers before. I would try putting the Google DNS servers in front of the Cloudflare DNS servers and see whether that fixes the issues.

10

Didn’t fix it

11

Are these DNS servers provided via DHCP (from your router)?

If so, did you change the order of DNS servers on your router too?

12

Nope, I set them in my OS manually. My DNS was initially set by my router, but I changed it and that made no difference. I’ll try changing the order in my router though in case these settings are somehow still being used from there

I don’t see how that’d make a difference though, since my device is the only one with this issue

Update: the issue is still present with my router’s DNS set to 8.8.8.8 and 8.4.4.8

13

I’m still having this issue.

Another thing I noticed that may or may not be related: IPv6 is broken. Running ping -6 www.google.com says “Network is unreachable”, despite other devices on the network having no such issues.

14

Primary is 8.8.8.8 secondary is 8.8.4.4 for Google.

15

Right, not sure why I missed that. It was correct in Manjaro but not on the router. We’ll see if that changes anything

16

Didn’t change anything

17

It really doesn’t look like DNS to me. When this happens, I can’t even ping an already resolved IP

18

Seems to be a bit better with Bluetooth coexistence off (bt_coex_active=0) in the iwlwifi.cong, but it only lasts longer

19

So, something interesting I just figured out. If I keep ping running in the background my connection stays up. That’s not an ideal workaround, but perhaps a clue as to what’s wrong?

20

I tried disabling MAC address randomization in my NetworkManager.conf:

[device]
wifi.scan-rand-mac-address=no

Now KDE doesn’t give me the “limited connectivity” notification, and I have to reconnect less frequently. I have yet to test it under load

Edit: it did it right after posting this, but went away on its own

21

This appears to have been fixed by an update at some point
