Disappearing network

Linux Support
1

Hi guys

Over the last couple of days I’ve been experiencing a strange problem where the network will just randomly shut down and the network icon on the Panel disappears, I’ve always experienced the network dropping out now and again but it will normally reconnect after a minute or two , but this is different in as much as the only way I can reconnect is a reboot, once rebooted the connection is restored immediately and everything back to normal,

This has only started in the last few days after a kernel update, I’m not saying that has anything to do with it but it does seem a little coincidental

Any help would be much appreciated

Assuming you are talking about wireless. It could be because of powering the adaptor down.
When this happens you could try to bring it up again (replace wlan0 to suit):

sudo ifconfig wlan0 up

Thanks SeZo

I’ve taken a note of that command and I’ll try that next time it happens, there’s no saying when that will be as it’s quite infrequent and random

Many thanks

Also, the next time the networkmanager icon seems to have disappeared … please post the output from:

nmcli nm status

and see if it comes back if you run:

nmcli nm enable false

then

nmcli nm enable true

I take it this is a wireless connection ?

Thanks Mark

Yes it’s a wireless connection,

Should I follow these commands after SeZos instruction or in place of ?

If SeZo’s command works … do mine next time.

If SeZo’s doesn’t work … try mine.

This is the exact fault I had with my original Acer Aspire One, and I solved it by buying a seperate USB wireless adaptor :frowning:

Ok it happened again so I went to open a text document I had SeZos command copied on from his last post and it wouldn’t open in fact no text document would open, so I’ll have to write it down and try again the next time it happens

It seems you have other problems if you cannot open a text file. Have you tried to open it from the command line?
That way you might get some clues.

No I haven’t, I didn’t think to do that but I’ll try that next time
