[Solved]Network Manager issue

Hi,

The problem I am facing is that, once I close the laptop and a while later I will not be able to connect to the wireless network anymore.

The exact things I am facing is, after I inputed my user passwd, I got into the KDE desktop. And then the network manager will not be able to show any wifi network, just like it is blocked or  sth else. I am sure that the kwallet process and network manager process are all running.

I am just wondering is there something I miss -configured? I have read wiki chapters before I use kwallet or openpgp or kde.

--------------
Here is what I have done regarding my Arch Linux:

* I use KDE5 meta
* I use Kwallet with OpenPGP keys, not bluefish
* The wireless network I try to connect is a university wide network.

======================
My solution:
It turns out to be a bug in networkmanager-1.4, I downgrade to 1.2.5dev+5+g99e34d7-1 and it works fine.

I may be affected by a similar issue. After resuming from suspend I must restart NetworkManager service, otherwise applet shows no networks available. I'm on KDE as well. It's probably caused by recent Network Manager update but I didn't try downgrading yet.

Have you checked the output of `rfkill list`?

Re: [Solved]Network Manager issue

I've also noticed the same issue on my laptop. After resuming from suspend there's no wireless networks available, until I restart the NetworkManager service.
My main system with only wired connection is unaffected.

Apparently the issue should be fixed in networkmanager git: https://mail.gnome.org/archives/network … 00038.html

Also there's a networkmanager-1.2.5dev+5+g99e34d7-1 package pushed to [testing] yesterday, that I'm assuming would include the fix.

Re: [Solved]Network Manager issue

I was experiencing the same problem on my Acer Chromebook after the most recent update. Downgrading the networkmanager package seems to have fixed it:

# pacman -U /var/cache/pacman/pkg/networkmanager-1.2.2-1-i686.pkg.tar.xz

I'm running the 4.6.4-1-ARCH kernel and have a Qualcomm Atheros AR9462 Wireless Network Adapter. The version of networkmanger that appears to be causing the problem for me was networkmanager-1.2.4-1-i686.

I see the same problem - networkmanager doesn't show available networks. Try "iwlist scan" as root after resume.

Re: [Solved]Network Manager issue

networkmanager-1.2.5dev+5+g99e34d7-1, that was just moved to [extra] fixes the issue for me.
