Re: Wireless connection drops every few minutes, and the reconnects

Having used Gnome and found the network manager rock solid for a long time, I was surprised to find my wireless connection dropping after switching to kde. What I did was remove network-manager-kde and install wicd plus the wicd-KDE client. I did that two days ago and so far it's good.

EDIT: I have absolutley no idea what this means.

If nothing else helps, i'll try to replace KnetworkManager

**GreyGeek** · Nov 10, 2011, 11:22 AM

Re: Wireless connection drops every few minutes, and the reconnects

IF you do replace KNetworkManager, which I do recommend, MAKE SURE you install all of the wicd apps in the repository BEFORE you delete all of the networkmanager, nm-, plasmoids, etc, files associated with KNM. Then, configure wicd. Then restart the network or reboot, which ever is easiest for you. IF you delete KNM first your Internet connection will be broken and you won't be able to install wicd unless you run an ethernet cable from the back of your router (or modem) to your eth0 port on your laptop.

I experienced exactly the same problem you have. It is especially bad on KFN, because, for me, when I would inadvertently move my mouse while I was clicking on a button on a page on KFN, the busy icon would spin until the link timed out. Then I could hit the refresh button and it would quickly display the page I wanted to see. That "move" problem also occurred when I tried Konqueror and Chrome.

I tried setting some "param" options on my wireless driver, which helped some. (Use modinfo on your driver name. Any "param" listings are things you can set to 0 or 1 in "options.conf", which resides in /etc/modprobe.d/. I experimented with a couple of the most obvious.)

Then, my wifi (Linksys wrt54gl) went belly up. I replaced it with a TP-Link TR-WR1043ND wifi. I also stopped turning my router off every night (because, for a while, I was playing Angry Birds on my iPod or checking the UndergroundWeather radar after retiring for the evening.). I leave my wifi on 24/7/365, except when lightening is nearby. Now, I never get drop outs and the only time outs I get are caused by the KFN button problem, but that is going away when we switch to the new host and forum engine in the near future.

lol. Not -knm, -knn. Or just do an

Code:

lspci -k

And post the output here. I wanna find out what your wlan driver is.

Re: Wireless connection drops every few minutes, and the reconnects

Code:

~$ lspci | grep Network

will avoid a page of output.

Re: Wireless connection drops every few minutes, and the reconnects

Yeah, but I wanna know the driver too. marvo, look for a line like this in your lspci output, it will be at the very end:

Code:

Re: Wireless connection drops every few minutes, and the reconnects

Hm. All the bug reports I've found point to WPA security. How about we try to connect you without network-manager?

Code:

sudo service network-manager stop
sudo ip link set wlan0 down
sudo ip link set wlan0 up
sudo iwconfig wlan0 essid "NAME OF YOUR NETWORK"
sudo dhclient wlan0

**marvo** · Nov 11, 2011, 01:49 PM

Re: Wireless connection drops every few minutes, and the reconnects

OK i'l try that tomorrow.
My battery is almost empty and i don't have the charger here...

BTW, i don't have any security enabled on my net.

I know, that's why we didn't give out a password.

Re: Wireless connection drops every few minutes, and the reconnects

I just tried to connect "Manualy" and as far as i can see, it did not work.
When i stoped the network manager, it says that its stopping the service, 'Waiting...' and it jut kept on waiting for 10-15 minutes.
I canceled the command and tried to do it again then it said that it was an unknown service, so i guess it had stopped.

The other commands ran smoothly (At least i thin so) but did not give any output.
But when i tried to launch dhclient nothing happened, no output it just kept on waiting, and no internet connection.

I restarted the system to ge the internet back. -Maybe i just could have started the network manager again intead...?

EDIT: I tried again it this time it worked. The service stopped and let me back controll of the terminal.
It also connected to the internet, turned out that i forgot that Linux is case senitive (After years of windows usage, whitch is not case sensitive as you probably know

) so i typed the "wrong" ssid LOL.

I'l see how long it stays connected now.
