Problems with NetworkManager and /etc/resolv.conf similar to previous problem

Yesterday there were over 1500 updates for Tumbleweed. Today, over 300. Starting yesterday I had problems connecting to the internet and my wireless adapters. There were similar problems in a thread a couple of weeks ago with a grayed out NM icon and /etc/resolv.conf with no nameserver address. I solved the /etc/resolv.conf problem the same as before by deleting and rebooting. I have two wireless adapters but only one was recognized.

Subsequent reboots left me with a blank nameserver address in resolv.conf again and still only one adapter recognized so I switched to Wicked. The second adapter was recognized under Wicked and reboots don’t cause a problem connecting to the internet. Is anyone else seeing anything like this?

With respect to NM, it might be useful to see what interfaces are reported from NM’s POV:

nmcli g
nmcli d

and

/sbin/ifconfig -a

I’ve seen this ( and seen it reported ). I stopped the network, removed the file, restarted the network instead of rebooting. Haven’t found the culprit yet. There should be one though.

I’m not really surprised that these commands don’t tell me anything different than just watching the behavior of my system. If I switch from Wicked where everything is working to NM, everything works with NM also. If I stop NM and then log out/in and start NM again, only one wireless adapter is working but the internet is also working.

If I reboot with NM running, I get /etc/resolv.conf with no nameserver. Then I have to stop NM, delete resolv.conf and start it again to get back the internet. I’ll just stick with wicked for the time being.

Just a bit confusing, which is why I requested output. When you’re in the situation where /etc/resolv.conf has no name server, does the following command then rectify that?

netconfig -f update

Well, I would test that command except the problem with the nameserver has seemed to have cleared up. I rebooted three times with NM running and each time I eventually connected to the internet with only one of my wireless adapters. When my system first boots, I get a spinning blue circle around the NM signal strength icon with an orange exclamation point. Then some pop up windows say that “wifi network could not be found” and “(name of wireless adapter) was deactivated.”

Then it connects to the internet anyway and says my wireless adapter is activated (but only one and the other one isn’t recognized). And a check of /etc/resolv.conf shows a nameserver address.

Ok, so you’re connected now, but not consistently?

This is the bit I’m not understanding. You say it isn’t recognised (you mean not present the NM GUI?)… so I’m assuming it doesn’t appear as a managed device via

nmcli d

What about the following?

/sbin/ifconfig
/usr/sbin/iwconfig

Hello mod,
I have this bug on WiFI connection with Tumbleweed. My WifI hardware is correctly recognised & correctly connects but DNS resolution fails. This does not occur with Ethernet connection.
I can confirm that your solution:

sudo netconfig - update

does restore DNS resolution immediately & remains working after subsequent reboots.

Many thanks for your help!

I’m glad that the name resolution is now working properly, the but the netconfig command isn’t a solution as such, just a (manual) way to force an update from the DNS server.

yes

What about the following?

/sbin/ifconfig
/usr/sbin/iwconfig

Both the ifconfig and iwconfig commands show there is only one wireless adapter recognized. With wicked, both adapters are recognized.

Understood Deano. I would be happy to help developers in debugging. Before searching bugzilla I’m wondering if anyone has a bug# I should subscribe to?
