Ubuntu Networking :: Wireless Down On Reboot - No Hardware Present

Oct 1, 2010

i installed linux on this laptop around 2 years ago (hp g6000 laptop) with internal wireless card and was unable to get the internal wireless card to work under ubuntu. so i purchased a linux supported usb wifi stick, which worked perfectly (connected automatically on boot) each time. however, i moved house recently and lost this usb wifi stick. i am currently using a ethernet connection to my hub and have updated ubuntu to the current version. all software is also up to date. since i lost my old wifi stick, i have used this connection, however, yesterday when i was on videos, all of a sudden (without me having done anything {intentionally anyway}) i see the wireless connection graphic at the top right of the screen! both green dots lit and the connection was live! so i disconnected the ethernet and used the wifi all night without a hitch.

i was extremely happy with what had happened and could not work out why it had decided to work (having not been aware to doing anything, except sit and watch a videos video). so i shut down, go to bed, go to work the next day and come home looking forward to browsing the web from my sofa, and guess what, no internet connection once i logged in! i just think 'if it worked last night, it can work now'. i have ndiswrapper and i have the .inf driver file for the internal card installed in ndiswrapper. i have opened that tonight and it looks okay - except it says 'hardware present: no'. i do not understand what has happened at all. (also there is a wifi 'on off' switch on the front of the laptop, with an orange led but neither position makes any difference to the card working or not and it hasnt changed positions since i moved house (to the best of my knowledge anyway).

Ubuntu Networking :: Wireless Networking Quit After Reboot?

Feb 27, 2010

I've had my wireless networking (on an Acer Aspire laptop) working perfectly well for at least six months.Now, quite suddenly, after a reboot I get the message from wicd, "No wireless networks found". I probably was running a week or so before that without needing a reboot. Windows wireless is fine (I'm using it to send this post).In addition, my sound stopped working and I see a fleeting message to the effect that the sound system is reverting from analog to digital.I'm running Kubuntu 9.10. My guess is that something in a recent round of updates knocked me out of the box. How can I proceed to set things aright?

Ubuntu Networking :: Need To Reinstall Wireless Driver After Reboot

May 28, 2010

I've been searching forums like for 2 days, but couldn't find any similar problem.
First of all im running Ubuntu 10.04 desktop version on my netbook Acer aspire one (AOD150)
Every time i turn off my netbook and after turn it on, in "Hardware drivers" it says that driver for wifi is not in use, also button for switching on/off wifi is not working.
So everytime i start up i have to go into "Hardware drivers", remove driver for wifi, and then activate it again. And everything is working gr8 after. Its just too annoying to do it everytime.

Ubuntu Networking :: Wireless Fails After Reboot / Suspend

Dec 30, 2010

I recently installed Ubuntu 10.04.1 LTS and have it set to dual-boot with windows 7 on my gateway tablet PC. Since installing, sometimes when I suspend or reboot, my wireless does not work. To be more clear - it is working fine, then I either suspend/reboot, then I come back and no wireless networks show up at all. I can still connect with ethernet cable though. I can solve it by rebooting multiple times (usually around 1-5 times) and then it (magically) seems to work again. I have also tried switching from network-manager to wicd, but the problem persists. With both network-manager and wicd, I've tried simulating a reboot for the wireless by using the command 'sudo modprobe -r iwl3945 && sudo modprobe iwl3945' (network-manager) and 'sudo /etc/init.d/wicd restart' (wicd), but these do not seem to work.

Ubuntu Networking :: Wireless Randomly Disconnects - Only Works Again After Reboot

Jul 3, 2010

I'm having a problem with my wireless connection. When it runs, it's perfect, but every once in a while (and increasingly more often) it randomly disconnects and doesn't reconnect when I click reconnect, even if I manually disconnect it. Every time this happens, I have to reboot the system, after which it works perfectly. Then it dies again.

I've checked around the forums, there are some similar threads but they seem to be specific to the wireless card. The reboot method works, but I'd really like to find a way to solve the problem without having to resolve to the Vulcan nerve pinch. I'm a real newbie to Linux and the more complex side of computers in general, and I hardly know what is what, so please excuse me if I seem a bit thick.

Ubuntu Networking :: Wireless Connection Requires Router Reboot?

Feb 11, 2011

I was having an issue with my wireless connection last week, and sometimes even my hardwired connection. It had seemed like every time my PC went into standby, or any low-power mode, the WiFi would stop working. I used the "power off" command and got it back and running. When I boot up the computer in the morning, I am unable to connect until I reset the wireless router. Unfortunately, I did not have the presence of mind to get iwconfig first thing in the morning, but I did reboot the laptop and grabbed iwconfig before I connected and after I connected. Now, for some reason, the router worked when I rebooted, but I had to reset it this morning. Any ideas? iwconfig below:

****Before Connect****
jake@jake-laptop:~$ sudo iwconfig eth1

Ubuntu Networking :: Hang On Reboot When Connected To NFS/ldap Server Via Wireless

Jun 18, 2010

School with linux running on students' laptops, connecting via wlan to a Debian NFS and LDAP server. Every student logs on his/her profile residing on the NFS server.The clients are set up with autofs. Earlier, I had set up the wireless network in /etc/network/interfaces, but this time I decided to configure network manager so as to bring up both wireless and wired network before logon. This setup has been working on for the last fire or five years with only minor changes. Also worked with Karmic Koala, but still with the interfaces file instead of networkmanager. The Vostro is also new here, we've previously used mostly Dell Latitude D505s.

So here is what works:

1: Clients can log on to LDAP and NFS servers both wired and wirelessly. Everything is smooth.

2: While on LAN, shutdown and restart works flawlessly (and quick as a breeze, I'm really impressed by startup/restart/shutdown times, under 25 secs!).

3: Shutdown and restart also works wirelessly when doing it either from a local account or from the GDM chooser.

What doesn't work, however, is shutting down or restarting directly from a networked account connected while only being connected over the wireless network. This is what's being displayed on the terminal after it has tried tho shut down for a while:


The system is going down for halt NOW!

acpid: exiting
init: cron main process (1011) killed by TERM signal.
init: tty1 main process (1365) killed by TERM signal.


If I try ctrl-alt-del at this stage, it says:

"init: rc main process (3030) killed by TERM signal"

"Checking for running unattended-upgrades: "

And then it will hang again, until I hold the powerbutton for some seconds. The unattended-upgrades part is what seems to be the culprit. I suspect it is about the wireless network not being connected any longer or something like that, but I'm not sure about how to go about debugging shutdown scripts here. I'd be grateful for pointers. I will try and see how it goes with the old interfaces file setup, but I'd rather make nm work.

Networking :: Wireless Network Times Out - Will Not Restart Without Reboot

Nov 1, 2010

I had been manually starting my wireless network with "sudo iwconfig wlan0 essid "my wireless router id". The network would start and work flawlessly for weeks at a time. I can't ask my wife to find the essid in the terminal and then start wireless manually when I'm not here. She hates and fears the terminal. So I downloaded gnome network manager for a point and click interface on gnome panel.The network would start fine but shut down after anywhere from one to six hours. It would then refuse to restart manually or otherwise. I completely uninstalled network manager and tried wicd instead. The same basic problem is happening. The network will restart if I reboot the computer. My system:

Desktop computer acting as proxy server for the internet. Internet connection is by a dial up modem. This computer uses a wireless pci card connected to a dedicated hub. This is for file sharing via nfs. The OS is ubuntu 9.10. My wife's computer sharing the internet using a proxy to my computer. File sharing via nfs and a wireless card. Also running ubuntu 9.10. This same basic system worked flawlessly under Ubuntu Hardy.My desktop was updated recently with new hardware which created the need to move to Ubuntu Karmic. Some hardware was too new for hardy to deal with.

Ubuntu Networking :: Reboot "looses" Wireless Device?

Sep 12, 2010

I installed Ubuntu 10.04 for the first time and had a few issues to put my laptop's wireless device to work (see thread [URL]I am now able to use the wireless connectivity but I still have a problem. Every time I reboot Ubuntu, the system does not seem to recognize that a wireless device is present. To overcome this problem I remove the driver and once this is done I activate the driver.The system then finds the wireless device, enables it and connects to the default wireless connection.

Ubuntu Networking :: Bluetooth Adapter Not Present / Get That?

Dec 22, 2010

I have been using ubuntu for a few years now but am a noob when comes to the technical side of things, so apologies for my lack of knowledge.

I am using ubuntu 10.10 on a ZOTAC IONITX-A-U Atom N330 1.6GHz Dual-Core Mini ITX Intel Motherboard and since I have upgraded from 10.04 I no longer have blue tooth capabilities. I have a logitech mx 5500 wireless keyboard and mouse, which uses a bluetooth dongle. This is the strange part as they have both been working until recently.

They both lost their charge and after replacing the batteries in my keyboard it no longer is able to connect. The mouse however works fine, until I dropped it So I bought a microsoft explorer mouse which came with its own bluetooth dongle. Which I plugged in and the mouse works fine.

But when I go to System> Preferences> Bluetooth

I get Bluetooth adapter not present and Your computer does not have any Bluetooth adapters plugged in.

I have spent the last week googling this and can't seem to find any relevant info.

I ran this in terminal code...

Am I wrong in assuming that the logitech and microsoft dongles are being seen?

I have also removed and reinstalled bluetooth and bluetooth manager in the software centre, and the same with synaptic package manager, to no avail.

With both dongles plugged in could this also cause a problem?

Is there another way of starting the bluetooth?

Ubuntu Networking :: Connecting To Router After Reinstall That Weren't Present Before

Dec 8, 2010

I am having some bizarre problems with a 10.10 install which I am hoping someone here can give me a little input on. Some background info: I have a laptop which I had originally put 10.10 on about 4 weeks ago. I was using the Network Manager applet to change the MAC address by entering a valid MAC in the "Cloned MAC Address" field, and then connecting to a network. This suited me fantastically as the applet applies the MAC to any interface that connects - ie. the internal Intel card or the more often used external USB RTL8187L. For reasons which would take a lot of explaining (and now kicking ones self in the head) I had to install Windoze on the machine for a week to get some specific stuff done - but have now come back to 10.10.

The problem: So just as before, I installed 10.10, connected to my router (without changing MAC) installed system updates and other packages such as Macchanger etc and got the system working and customised how I like it. Problem is, now when I enter an address in the Cloned MAC address field and attempt to connect, the applet just sits there with the pulsing waves likes it's trying to connect but it cannot. Whilst this is happening, ifconfig -a shows that the MAC has indeed been changed. Until I remove the Cloned MAC address entry, I cannot hop on my router - or any other for that matter. Before, these steps were enough to ensure correct and functional cloning.

Things to know: This happens whether I am logged in as me or root. There is no MAC address filtering on 3 routers I have tested on (different brands). There is only MAC filtering on a 4th, and in that case, the cloned MAC is in the routers whitelist. This happens whether I specify IP details and if DHCP is used. All 3 routers without MAC control have been reset. All settings to do with wlan0/wlan1 in the network applet have been removed and re-entered. It happens on 2 different wifi cards (Intel and RTL8187L) but they worked before re-installation. I have also tried the usual commands in the terminal such as:

ifconfig wlan0 down
macchanger --mac (mac here) wlan0
ifconfig wlan0 up

also tried hwaddress ether 12:34:56:78:90:00 etc - The problem doesn't seem to be in changing the MAC, more the functionality of wlan0/wlan1 afterwards. I have also tried (although, it worked fine without this before) adding lines to /etc/rc.local and /etc/network/interfaces. It would be worth noting that either networking was restarted or the machine was rebooted after each alteration. No avail.

I can't think of anything significantly different that I have done to this re-installation compared to the first time, so I am not sure if perhaps in the time that it took me to reinstall 10.10, a package update has come out which has altered something and it's chucking a spanner in the works. Having said that, I even reinstalled AGAIN without applying any updates and same result. I would consider myself moderately experienced with Linux - so I am pretty sure that I am not making a complete n00b mistake... this situation is just so puzzling. I have been googling for quite some time and can find others with similar problems, but no actual solution.

Ubuntu Networking :: Lynksys WUSB54GSC Present On USB List But Not Operating?

Dec 29, 2010

I just installed the latest version of Ubuntu Desktop. When I do a "lsusb" I can see the device present but the light is not on and I cannot see the wireless router.

Amazing that I can be at version 11.04 and it still doesn't see a wireless device and install it.

So, my guess is that I have to root around about 5 different places and gather up a bunch of files so I can get this running.

Ubuntu Networking :: Mount Network Drive Automatically ONLY When Present?

Jun 10, 2011

I have a network drive connect to my lan with iomega's iconnect device. I am getting tired of mounting the drive manually each time I want to use it. I would like therefore to have it mounted automatically on boot by placing a line in fstab, but since the computer (a laptop) won't always be connected to my home lan, this might cause problems. Is there a way to list the drive in fstab so if the drive is not present it will just move on?

Networking :: Device Eth0 Does Not Seem To Be Present - Delaying Initialization?

Jun 17, 2009

I have swapped out four known working, different bran network cards. Each one I get the same error as in the subject. If I boot to a Live CD such as CentOs 5.3 LiveCD both Nics are given an IP. This seems to only be happening with my CentOs 5.3 server install.I noticed the CentOS Live CD the Nics were reversed from eth0 to eth1 and eth1 to eth0.

At the moment as of the output of the commands, I am running two identical Nics, since the first one has always worked. I have previously used an rtl8139, 3com c3905-TX, onboard Rhine III based (now disabled) Here are steps I have done to try and figure this out:


[root@centos ~]# lspci | grep -i eth
00:0a.0 Ethernet controller: VIA Technologies, Inc. VT6105/VT6106S [Rhine-III] (rev 86)
00:0e.0 Ethernet controller: VIA Technologies, Inc. VT6105/VT6106S [Rhine-III] (rev 86)


[root@centos ~]# cat /var/log/dmesg | grep -i eth
eth0: VIA Rhine III at 0xee800000, 00:1b:11:bb:17:7d, IRQ 177.
eth0: MII PHY found at address 1, status 0x786d advertising 05e1 Link 45e1.


I went through the system-config-network-tui. I copied /etc/sysconfig/network-scripts/ifcfg-eth1 to the ifcfg-eth0 and edited for sanity. and as stated earlier, have swapped out four different nics for eth0, and booted to two different LiveCD's. Both LiveCD's work fine.

CentOS 5 Networking :: Broadcom BCM5700 Gigabit Not Present In 5.3

I just kickstarted this box - I used eth0 and had no issues. After booting - eth0 is not available/present. This was not an issue in 5.2. This is a dell 4600 - both the 100mb intel and gig broadcom are onboard. I am about to try a different kernel. This is not a show stopper - it's plugged into 100m switch and I can just use eth1 - but I am curious as to what is different and why this no longer works.

Networking :: Unable To Configure The Network Card Because The Kernel Device Is Not Present

Jan 28, 2010

I have installed Linux SuSE 10.3 on a PC (Lenovo Thinkstation A58). However, when I start the computer I get the following error message:

"No valid Host_ID or host-name found."

I then use YaST to set up the network. I get the following error message:

"Unable to configure the network card because the kernel device is not present."

The computer has Windows 7 installed and everything seems to work fine. The LED on the Ethernetplug is blinking when using Windows, but not when using Linux. I guess this means that there is no driver for the Ethernet card (Marvell Yukon 88E8057). I have not found any driver for the card and am considering buying a new one. Which PCI card works with SuSE Linux 10.3?

Debian Configuration :: Wrong Name For The Wireless Card On Reboot

Feb 17, 2016

A couple of days ago I asked why my pc changes the wireless card name.It switches between AR9285 ( right) and AR5008 ( wrong). Well, it is not the case. When system identified with AR9285,it loads ath9k and I can connect to the router. When system identifies my card as AR5008, no kernel module is present at all ( lspci -k). The wrong card name occurs only when system rebooted. If I gracefully shut down the system, it always comes up with a right name for the card( AR9285). So, how to force the system identify my card right no matter if I reboot or shut down?
