Wifi: stuck on "waiting for beacon from ..."

Aurel07 · 2014-02-12 04:03:37

Hi,

Today, my laptop won't connect to the wifi while I have been using it for 2 weeks now. dmesg says something like this:

authenticate with ...
send auth to ...
authenticated
waiting for beacon from ...

Where ... stands for the SSID, and there is a wlp2s0 before each line. And it stays on this line and does not connect. Btw, I'm using my cell phone on the same wifi network. Can somebody what can solve my problem, or at least what a beacon is?

Thanks!

What does the output of rfkill list have to say?

Thanks for the link. The problem is rfkill is not installed, and I can't install it without internet...

I myself am pretty stuck here...

Edit: I'm more resourceful than I thought, here is the output of rfkill list:

0: phy0: Wireless LAN
Soft blocked: no
Hard blocked: no

Do you have iw ?
Try sudo iw wlp2s0 scan
Can you USB tether your phone?
Can you do an off line package install ?

I've installed iw and rfkill by downloading them from the repos, and transferring to my laptop. USB tethering don't work either, but I don't think it ever worked.

iw wlp2s0 scan gives me lots of output. What should I look for?
(beacon interval 100TUs)

And thanks a lot for your help and patience.

Hey, no problem. If iw gives a lot of output, then your wireless is working and you do not have a problem with the radio being disabled. Check to see if you can see your access point in the output.

So, moving to the next step, what are you using to control your network? netctl? wicd? NetworkManger? Ensure you are using only one.
What kind of network is it? Open? WEP? WPA1/2?

Assuming you are using netctl, did you write your configuration file by hand? Or did you use a tool like wifi-menu?
Do you have administrative rights on the access point to which you are trying to attach?

I have access to it, I see its SSID in the output of iw scan, and I can't find any error. I use networkmanager through gnome, so everything is automatic. The network is WPA 1/2 and the pass is good. Unfortunately, I have no admin right on it.

Ok, out of despair, I braved my landlady and restarted the router... and I can now connect. I don't get it, is it possible that it didn't come from my laptop? Here are the output of dmesg before and after:

Before

I am running out of ideas here. I have not had a great relationship with NetworkManager; it has let me down often enough that I avoid it when I can.

Were I you, I would disable and stop NetworkManager, start netctl, and try wifi-menu. Not a solution, but a work around to see if you can get it working.
I would suggest ensuring your system is fully up to date, but that is a bear without a working network connection.
Is the kernel you are running the same as the one that is installed? Check the output of uname -a and compare it to the output of pacman -Qi linux
If they are out of sync, try to reboot.

Edit: I see we were posting at the same time again Disregard. It sounds to me like the router was in a strange state. What flavor is it?

It's a Netgear N600 dual band wireless. I wil take advantage of having an internet connection to install most of the core repos, so that I have the tools needed, just in case. And I'll try your suggestion next time too. Thanks again for your help.

Coincidentally, that is the exact router I have. I used to have all kinds of problems with that router and had to reboot it every few days. I think it has (had) a memory leak.
That router is well supported by DD-WRT; changing the firmware solved all my issues and up times measured in months is now common. I know that doesn't help you in your situation
