wrighty338 Posted March 21, 2022 Share Posted March 21, 2022 I usually reboot my R2 daily before work but on the days i forget i seem to be getting about 36 hours since the previous reboot before DNS gives up. My modem lights are staying on and my work VPN keeps functioning (wifi) but when i try load a page on my PC i cant get to anything without rebooting the R2 - post reboot everything comes back immediately The network icon on the PC seems to think the connection is still up. I doubt its my provider going down so often but cannot rule it out. Iv tried my providers DNS and iv manually entered different public DNS address' to try resolve. The only message in event viewer seems to be: Name resolution for the name wpad timed out after none of the configured DNS servers responded. This may mean i need to do some network adaptor troubleshooting - one of the suggested resolutions could be to turn off IPv6 - iv done that now and will see if i note an improvement Has anyone reported anything similar? Any suggestions on any other settings i might be able to change on the R2 to try resolve? The pc is about to be retired so for now a reboot will suffice and i wont spend too much time on it if the pc is at fault Link to comment Share on other sites More sharing options...

If so, would you mind downloading the log file from System Information and send the whole thing over? We can also get a dev to debug that to help with troubleshooting.

wrighty338 Posted March 21, 2022 Author Share Posted March 21, 2022 Log attached, it happened again at 20:31 tonight. I tried to connect my phone to wifi at this time and browse but was unable to connect - seems R2 was not happy at this point. Iv moved onto google public dns servers now as opposed to the "fastest" servers suggested by Namebench log-1647894969199.txt Link to comment Share on other sites More sharing options...
wrighty338 Posted March 22, 2022 Author Share Posted March 22, 2022 And again 9:35 this morning, log attached. Work VPN stayed up, PC could not connect to anything and phone could not connect to wifi. Reverted to upstream DNS now, and also having read a few other threads iv increased the DHCP time to 168 hours. no problems found on my network adaptor following troubleshooting last night. log-1647941791785.txt Link to comment Share on other sites More sharing options...
Netduma Liam Posted March 22, 2022 Share Posted March 22, 2022 Thanks, I'll pass these on to a dev to investigate. Could you confirm if you still experience the issue using upstream DNS? Is that what you meant when you said you're using your providers DNS? Link to comment Share on other sites More sharing options...
wrighty338 Posted March 22, 2022 Author Share Posted March 22, 2022 Il see how we get on Liam, Yes its back to default upstream now so im just guessing it points to my providers stuff if nothing is specified. I was tempted to leave them both enabled and let upstream be the primary and google be the secondary - it seems more resilient that way but back to default for now.

Yeah it just uses whatever DNS the upstream router/modem uses. I'll let you know once I've heard back from devs! Could you just confirm that the PC is connected to the R2 via wired?

Administrators Netduma Fraser Posted March 22, 2022 Administrators Share Posted March 22, 2022 If you set the DNS on a particular device manually does it continue to have internet when others fail? Link to comment Share on other sites More sharing options...
wrighty338 Posted March 22, 2022 Author Share Posted March 22, 2022 I can try it, iv not noticed because so far iv only noticed on my pc my work laptop continues to function while the pc is unable to load pages Link to comment Share on other sites More sharing options...
Administrators Netduma Fraser Posted March 22, 2022 Administrators Share Posted March 22, 2022 If you could try that and let us know while the devs take a look that would help narrow down the issue Link to comment Share on other sites More sharing options...

To do this, go to Network Settings -> WAN -> Enable remote access to tech support. Once done, Save Settings and let us know, a dev will then take a look at what's happening.

wrighty338 Posted May 6, 2022 Author Share Posted May 6, 2022 Not sure if this was a one off upstream issue, but i got the same problem once again today. Not sure if iv lost any settings through power cycling the R2 that were applied to fix this last time around. My equipment is power cycled regularly so unsure if this the case but it was the exact same situation as before where my work machine continued on its VPN and i lost everything else. Fri May 6 14:25:06 2022 daemon.err dnsmasq[3035]: failed to send packet: Resource temporarily unavailable Fri May 6 14:25:16 2022 daemon.err dnsmasq[3035]: failed to send packet: Resource temporarily unavailable Fri May 6 14:25:26 2022 daemon.err dnsmasq[3035]: failed to send packet: Resource temporarily unavaila I came back to reboot the R2 and DNS has come back up while im in a meeting so really not sure but il keep an eye on things the next few days. Iv not touched any settings since last time when things were fixed so it could well have been my provider i guess. Link to comment Share on other sites More sharing options...
Administrators Netduma Fraser Posted May 6, 2022 Administrators Share Posted May 6, 2022 Thanks for that, if you disable it from LAN/WAN see if it makes any difference please as we've been testing that and had some unusual results that could have similar issues to this Link to comment Share on other sites More sharing options...
wrighty338 Posted May 6, 2022 Author Share Posted May 6, 2022 So flick upstream DNS off ok Do you want me to configure DNS override to the same thing you might be using or shall i put it to any public servers? Cheers! Link to comment Share on other sites More sharing options...
Administrators Netduma Fraser Posted May 6, 2022 Administrators Share Posted May 6, 2022 Sorry, leave DNS as it is or disable then you could use 1.1.1.1 and 1.0.0.1 which is a good DNS. What I meant to say was disable IPv6 from LAN/WAN instead wrighty338 1 Link to comment Share on other sites More sharing options...
