Wakeup from sleep, fails to connect to wifi

[wulftone]

Hey all,

I just updated to Update Pack 4, and installed cinnamon.. pretty decent so far, though I do miss compiz's flexibility and ease-of-configuration. My issue is with the wifi. Here's the symptoms: I connect to wifi, then I close my laptop lid, then I open it and it tries to re-connect to the same network, but fails with "Authentication Required" and _no_ popup box for password or anything. I have to turn _off_ my wifi and turn it back on in order to connect. No idea what's going on or how to diagnose it... help?

Thanks!

What goes on when suspending is logged in /var/log/pm-suspend.log

As a general note: A good way to find out what's going on is to look at the output of

Code: Select all

dmesg | tail

This will basically give you the last lines of /var/log/kern.log
If that does not give a hint leave the '| tail' away or open the file directly and post the whole content.

The part that starts at 23056 is after I manually re-started the wifi--at which point everything was fine, but it should have done that automatically. : \ Not sure what's going wrong.

Besides the Samsung part it looks the same for me. Do you know where you have samsung-tools from and could you reinstall it please?

[dgrant]

I have the exact same problem that you do, and it only started happening after I upgraded to the latest update pack. Did you ever manage to fix the problem?

[wulftone]

I removed samsung-tools, and there's no change in the behavior. It still fails to re-connect unless I cycle the wireless off/on.

@dgrant: Nope. Never fixed it! I've just been living with it... annoying, but whatever. I like Cinnamon regardless. Did you ever fix it?

[wulftone]

Anyone got any more ideas on this topic? I'm fresh out. It still fails to reconnect, and if I cycle the wifi power, it asks me for a password for my own network, even though it's stored. I just have to press enter after I cycle the wifi power, but it should just connect without the dialog box if the password is stored, right?

[thesilverring]

I too had this problem. I fixed it by checking the "Available to all users" box in the "Wireless security" tab of the network options.

Network settings -> Wireless -> (select your network) -> options -> "wireless Security"
check the "Available to all users" box at the bottom.

Ah, great. Thanks for that tidbit. Unfortunately I'm not using LMDE right now, so I can't verify. I installed regular Mint 13 Maya Cinnamon and it worked fine out of the box. I figured it was a permissions-esque thing.

Hi there,

just encountered this issue, too, on one out of three laptops and your hint:

I fixed it by checking the "Available to all users" box in the "Wireless security" tab of the network options.

Network settings -> Wireless -> (select your network) -> options -> "wireless Security"
check the "Available to all users" box at the bottom.

did do the trick!

Thanks for sharing & Cheers, Erik
