Desktop WiFi stops after reboot for router but not phone

th flag
TimWescott

I have:

  • A lovely ancient desktop running Xubuntu 22.04
  • A Dell Latitude E7250 (5-year old 12.5" screen enterprise laptop) running Xubuntu 20.04
  • A Lenovo P53 (3-year old larger enteprise laptop) running Xubuntu 22.04
  • A Linksys AE6000 wireless adapter (lsusb reports ID 13b1:003e Linksys AE6000 802.11a/b/g/n/ac Wireless Adapter [MediaTek MT7610U])
  • A Netgear N900 dual-band wireless router
  • A Pixel 5

When I reboot the desktop, it stops being able to connect to the router for about a day (or perhaps exactly 86400 seconds), after which it spontaneously heals itself and connects to the router just fine.

If I set the phone up as a hotspot, the computer connects to it just fine right out of reboot.

I can see the router just fine in the network manager pulldown and using nmcli device wifi list.

At this point, I reach the end of my clue-rope, and I need to declare myself clueless.

I'm not sure if it's relevant, but the computer was doing the same thing using Xubuntu 20.04. I did a distribution upgrade, and I may have done a distribution upgrade from 18.04 -- so there may be some residual nastiness in a configuration file somewhere that's just been carried forward.

The same external symptoms happen with a Dell Latitude E7250 with Xubuntu 20.04, but they do not happen with a Lenovo P53.

In the case of the Dell, it works just fine off of my house router.

So somehow the problem is hardware- or installation related.

Here's a snippit from syslog, where the system is trying to connect to my wireless router at timshop24. My apologies for the huge data dump, but I'm not sure what's relevant.

It was a DHCP problem. I set up the wireless connections to look to the Google DHCP servers, and my problems seem to have gone away.

What happens if you run the command to restart Network Manager as follows?

"sudo systemctl restart network-manager"

There's some suggestions here: https://ubuntu-mate.community/t/network-connection-needs-restarting-in-20-04/24302

It says "Failed to restart network-manager.service: Unit network-manager.service not found." I assume this is a 22.04 vs. 20.04 issue, because while I'm using Xubuntu my understanding is that's just a different set of high-level applications and a desktop that isn't a bloated mock Mac monstrosity.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
