I have an Asus laptop with a BCM4318 wifi chipset. result of lspsci command about wifi cards:
Code:
00:09.0 Network controller: Broadcom Corporation BCM4318 [AirForce One 54g] 802.11g Wireless LAN Controller (rev 02) For some reason, I often get disconnected. Once it's disconnected, I cannot connect anymore and I need to reboot my laptop in order to get the connection back! I didn't have this problem when I was on Ubuntu 8.04. I checked in /var/log/syslog and I found this when the network is disconnected:

I am running (K)Ubuntu Lucid 10.04 64bit on a Dell Latitude E6400, WiFi Card Intel 5100. Never had any problems with networking. Up to about 2 weeks ago. I do realize there have been quite a few posts with this network adaptor, but non really described the problem I have here.
What happens is that suddenly the WiFi LED on the computer stops blinking, the WiFi connection gets disrupted, and the device is not recognized anymore when checking ifconfig. Only cold restarting the machine helps then... it will work for a while (between 1 and 20 minutes) and then crash again.
On Windows 7 the card works perfectly fine. With Ubuntu 11.04 in Live CD mode I have the same effects (connection crashes after a while). Also tried booting an older kernel, no success.
My exact hardware:
Code:
I notived the following problems in /var/log/kern.log

I was wondering if there's any way for a laptop to be both simultaneously connected to a wireless network, while at the same time acting as an ad-hoc network with local access to serve as a wifi connection for my mobile device, which would be ssh-ing into the laptop and using local resources.

Wifi getting disconnected very frequently in Fedora 10. I am facing issues in my Toshiba satellite laptop, after a fresh install of fedora - 10. After the install, The wi fi connection is dropping off very often, and even on keeping wpa_supplicant and wifiroamd in "active" state, the connectivity needs to be established manually.

Im using Ubuntu netbook remix on my wife's hp mini. Ever since I switched my router out this netbook will connect to my wireless network, then show a disconnected icon, yet the internet still seems to work. I've searched around and seen that other people have had this issue but I haven't seen anything on how to resolve it.

I tuned on my netbook and my wireless signal had a red exclamation.
Wireless is enabled.
Wireless Networks shows disconnected
I don't get it. Can't seem to get it to connect? How? If I open the connection information I can see the wifi networks around me. And edit/add/delete. But when I go back to the signal and click. it just shows wireless network disconnected and no option to connect. What to do? I have restarted the computer, router, cable modem, etc. Done the updates.

I have installed Mint8. I was using VPN connection before to be able to use skype (it's blocked in the Middle East...) but can't get it to work in Linux I've installed the network manager, added and configured the VPN connection but when I click on it to connect it doesn;t do anything. No window popping up, no error message... anyone has got an idea what else I should do in order making it work? or how else can I use skype without logging into private networks?
another "problem" we have got 2users on Linux and the other one cannot see the wifi icon in the bottom right corner on his desktop. after nm applet (or some command like that ) i got back that its been taken by another user. so can only one user see this icon on his desktop??

I had a problem with the new network manager a week ago and got it solved with help from the forum so now I'm back again. I have a dual boot with Windows 7 (I have to use it when serving my corporate masters) so I wasn't in my Fedora partition much this week.
I just noticed this and I'm positive it wasn't doing it before my network manager problem but I'm not sure when it started or if they're related.
I'm running F15. The machine is an HP Elitebook 8440p and has a wifi light that is also a touch button to turn the wireless on/off. Whenever there is activity on the network now it blinks between orange and blue. I know that isn't really a big deal but it's really annoying and is driving me completely nuts!! The normal behavior is orange when it's off, solid blue when it's on (or connected) and blinks orange/blue just while it's connecting. During network activity it's always been just solid blue and that's what I want.
I found a script that some Ubuntu users said fixed the same problem but when I tried to copy it the directory they said to put it in "/etc/network/ifup.d" doesn't exist. I'm assuming that's a distro difference between Ubuntu and Fedora?
Has anyone else seen this? Any ideas how to fix it?

How to enable wifi? I downloaded and installed Debian 6.00 and as I couldn't get online with my Tenda USB Wireless Adapter. I downloaded Debian 6.00 again, this time the CD Net Install version with Firmware included. However, the added firmware version of Debian does not find my wireless either. My wireless adopter is shown as Bus 001 Device 003: ID 148f:3072 Ralink Technology, Corp. RT3072 Wireless Adapter. There is a Network Icon in the Panel which when clicked shows "Create New Wireless Network". I have put in my ISP related network and my password and rebooted, but all I get is the message on my desktop:
"The Network Connection has been disconnected."
That isn't very polite, is it? Who has disconnected it and why remains a mystery to everyone except the culprit(s). I think I must have missed a basic step in the Wifi Enabling process. I checked the Use Permissions and everything is fine there, as User I have permissions to use modems and do networking and so forth. Also I should like to try "modprobe" but I see the package isn't in Synaptic Package Manager.

I'm using Xubuntu and i have set up my DSL connection manually. I get disconnected from the Internet within 2-3 minutes. I have to again select eth0 from the network icon in the taskbar. it connects well but gets disconnected again and again. I don't face such problem when i use Win XP.
Any idea what might have gone wrong ?

I have installed Fedora 13 and updated it. I simply cant use ssh to connect to this Fedora, not even locally. I have enabled port22 in firewall settings and nothing. Tried to disable firewall completely and nothing. I have disabled SELinux (not sure if it has something to do with this, but... ) and nothing. Entered "ALL: ALL" in /etc/hosts.allow and still nothing. Dont know what to do anymore.
Here is what happens when I try to ssh to this machine, even from it:
[flibio@surf ~]$ ssh localhost
warning: Need basic cursor movement capability, using vt100
flibio's password:
Authentication successful.
Disconnected; connection lost (Connection closed.).
Connection to localhost closed.
[flibio@surf ~]$
Looking into Services > sshd and it says "This service is dead."
So I tried:
[root@surf etc]# service sshd restart
Stopping sshd: [FAILED]
Starting sshd: : OpenSSH_5.4p1 on
: FATAL: Creating listener failed: port 22 probably already in use! .....
And still I get disconnected whenever I try to ssh to this machine from anywhere. Services says that sshd is allways dead, even restarting it but I can only restart it by doing a pkill sshd before.

Since I have started to use Ubuntu 9.10, I have had multiple wireless connection troubles. First of all, it says the signal is 2 bars, when in fact my router is right next to me as of right now. Second of all, when I try to connect to it, it asks for my password 3 times, then says disconnected. I'm on a hardwire right now, it's across my keyboard, and I'm in a tangled mess.

I logged on to one of my servers and ran a yum update, while the update was in progress my SSH connection got disconnected.
I logged in through a new connection when connectivity was restored and looked at running processes. It looked like yum was hung so I killed it (big mistake and one I won't repeat).
Now, when I try and run yum, I get the following:
Quote:
yum update: There was a problem importing one of the Python modules required to run yum. The error leading to this problem was:
Please install a package which provides this module, or verify that the module is installed correctly.
It's possible that the above module doesn't match the current version of Python, which is:
If you cannot solve this problem yourself, please go to the yum faq at:[url]
I have tried hunting around for the correct version of libelf without much luck.
Is there anything I can do to get yum working again?
The server is running Centos 5.2

My promlem is that I wrote a few simple script to monitor the network connection as follows:
script 1 "netmonitor.sh"
#!/bin/bash
# /usr/local/bin/netmonitor.sh
HOST=www.google.hu
ping -c 1 "$HOST" > /dev/null 2>&1 .....
So it's run every 5 minutes, and it works well, when it sees host is down, it restart the connection, BUT as the log shows below, about a half an hour after using the connection (for example the ssh through the internet or the vpn clients disconnected) , br0 (probably) goes down or something and the script needs always restarting the connection...
The log:
Fri Jan 21 14:45:01 CET 2011 Network is ready! .....
Fri Jan 21 15:55:41 CET 2011 Network seems down, rechecking...
Fri Jan 21 15:56:21 CET 2011 Network is down, restarting interface br0!
Fri Jan 21 15:56:48 CET 2011 Network is ready after interface br0 restart! .....
Then if I use again, its ready... Is it possible, that if system don't use the connection after getting the DHCP lease, it close the connection automaticly? Anyway it works ok, but I don't want to owerwrite my router's flash in every 5 seconds with te new lease, my script probably defeat it soon if I don't do anything.

OS: Maverick Ethernet driver: tested with sky2 an sk98lin This has been driving me crazy for the last few months: if I unplug ethernet cable while my laptop is on reconnecting it sometimes does not bring the connection back.
And once ethernet is gone nothing that I try seems to consistently bring it back. Rebooting, disabling/enabling the driver, disabling/enabling NIC in BIOS, changing driver from sky2 to sk98lin, deleting connection from Network Manager, resetting the router - nothing helps. It seems to come back randomly a few weeks later. Once I used live Ubuntu on a USB stick and ethernet came back not only on a live distro but then when I rebooted also on my main OS. But when I tried that trick next time ethernet was missing in the live distro as well.
Also once I was able to revive ethernet but compiling sk98lin driver, blacklisting sky2 and rebooting. Of course next time doing the same routine did not help. The thing is - ethernet works fine with either sky2 or sk98lin and I can unplug the cable and plug it back in most of the time without any issues. But then every so often - bang and I'm stuck with only wireless until ethernet suddenly starts working again.

This is not the common problem that's on the stickied thread. I'm able to connect to my wireless network perfectly. I switch between Windows to game and Linux for desktop, coding, and hosting, so I can tell it has something to do with ubuntu 10.10. When I'm connected to my wireless network, at random times, my internet begins to slowdown, then I get disconnected from the internet, but the taskbar says I'm connected. This problem only happens in ubuntu and not Windows for some strange reason.
The applications that are usually open do not cause it, because it still does it even though I have little applications open (Google Chrome, gedit). When I'm on Teamspeak 3, I notice my ping rises to the 1000s randomly, and I get disconnected. Once again that only happens on Ubuntu.

I am able to configure a working 3G connection but I do not want it to be enabled at startup. I want it "on-demand" and I need that it is easy for non-skilled persons, that is double-clicking a desktop icon. So I think I have to call a script or something else but I do not know the command.

my netbook shares it's wireless connection to my desktop. i've done this through the gui (edit connections > eth0 > ipv4 settings > shared to others) and it has worked for the last i don't know how many months.recently it had become a bit touchy with regards to how it was set up. it didn't work unless the netbook was already booted and wired in at the time of booting the desktop.now however it's gotten even worse and all i get when i connect them together is
"connection established" *pause* "disconnected" *pause* "connection established" *pause* "disconnected" *pause* "connection established" *pause* "disconnected" *pause* "connection established" *pause* "disconnected" *pause* "connection established" *pause* "disconnected" *pause* "connection established" *pause* "disconnected" *pause* "connection established" *pause* "disconnected" *pause* "connection established" *pause* "disconnected" and so on.
