Wi-Fi diconnects.
« on: August 21, 2019, 03:16:51 pm »
Why does Wi-Fi - Wireless LAN - disconnect ever so often? (When not being used)
Why is it not possible to reconnect?
Functionality is there - it just doesn't do anything. It is necessary to reboot, to get back on the LAN (and internet).

Define "ever so often" ?

Is it only after the PC has gone to sleep, and then been woken ?

No.
It happens in the middle of posting comments on FB, for instance, so it's got nothing to do with sleep function.
(Don't even remember it going to sleep, actually)
Sometimes, it stay connected for only 15 minutes - other times, it may stay online for hours.

The right-click menu on the icon, offers me an option to disconnect - but it is disconnected (not functioning), and the WiFi-LED is off.
It also has checkmarks in Activate network and Activate wi-fi network. Indicating it is connected.
Going to the connections menu (bottom item in right-click  menu), tells me the wireless was in use a few minutes ago. It also tells me, Ethernet was in use a few minutes ago - even tho there never has been a wire connected...
But it does indicate, that it has discovered, the network connection was lost (going the when online, it says "now").

When trying to create anew connection, a disconnect message shows upper right corner of the screen, and no new connection is created.

If you don't mind me editorializing...

That's the #1 reason why I hate NM - spontaneous disconnects.

It was a constant irritation, in the past, when I was alpha/beta testing Ubu, and a frequent problem, to this day, on public WiFi.

NM has never worked right, 100% of the time, and it never will IMO.

I've replaced NM with 'wicked' (WiCD) on most of my machines; especially portables. I've never had a problem with wicked - probably because it hasn't been maintained in years. Too many chefs spoil the broth, you know?

Anyway; not suggesting. Just saying, for the sake of conversation. I never miss a chance to hammer NM.

Carry on...   :)

@VinDSL: Thanks for recommending replacing the Networkmanager with WiCD! I had the same problem with frequent disconnects. So far WiCD seems to work much better.

There's a nice WiCD write-up, over of the Arch Wiki: https://is.gd/WvYk7g

And, here's a flash from the past, in the old Peppermint Forums: https://is.gd/HMzMxj

Most importantly...

Warning: Running multiple network managers will cause problems, so it is important to disable all other network management daemons.

What I do is select “download only”, for the WiCD packages, using Synaptic. Then I purge NM, install wicked; and reboot. That way, I don't have to worry about "running multiple network managers". After the restart, I config WiCD for my LAN; and away it goes. Generally speaking, I never need to touch wicked again.

I don't want to hijack this thread. Carry on...  :)
