Jun 16, 2010
I'm getting a little frustrated. My Ubuntu 10.04 has no wired nor wireless though i've got both. My computer is a Acer Aspire 5745G with atheros cards. i've been looking into this: Atheros but it doesn't help me when i've got no wired internet.I installed this: and it got the wired network working. So i figured that i'd run a update to see if my card would get any support. it didn't, and after i restarted my wired connection died too. I have reinstalled it sinceIf anyone knows how to do something 'bout this atheros card i don't want to do any working in windows, only games...

I have a laptop with Ubuntu 9.04 on it. I wanted to try out fluxbox, so I did a apt-get install fluxbox. When I went into fluxbox, I was having trouble getting connected to my network wirelessly. I saw a post online that said to install wicd. So I did a apt-get install wicd. This removed the Gnome network manager (nm-applet) which I didn't realize that it would do. I removed wicd when I saw this is what happened, and now I can't connect to a wired or wireless network. I tried connecting to my wired network, and I ran
Code:
sudo ifconfig eth0 192.168.1.115
but I still can't access the internet, or other things on the network.

I just installed (dual-boot with Vista) Ubuntu 9.10 in my Toshiba Satellite M300. The problem is that (when using Ubuntu 9.10), its network is dead, both wireless and wired. The LEDs of the LAN port don't even blink. My wifi is not also detected. Both of my wifi device and LAN port are functional when using Vista.

I am running ubuntu 9.10 on a dell xps m1530 laptop dual booting with windows 7. I am trying to achieve the following setup.
Wireless router <=========> Laptop <-----> Switch <-----> PS3
---- wired
==== wireless
Both laptop and ps3 have static ip addresses
The reason for this is I can connect to the internet on my ps3 through my laptop, and I can stream from my laptop to ps3 through wired connection. This works fine in windows 7 all I had to do was right click bridge connections. As I dual boot I don't want to have to make any changes to the settings on the ps3.
My interfaces are:
eth0 - wired
wlan0 - wireless
I installed bridge-utils and created a bridge and added both eth0 and wlan0 to it. However I could not get it to work. I have also tried internet sharing through network manager and firestarter.

I have just installed Ubuntu 10.04 on an HP Pavilion dv6000 series laptop, dual-boot. Everything is working except the networking. It can see wireless networks, and when I type in the password for my wireless network, it tries to connect, then asks for the password again. When I plug in the Ethernet cable, again it tries to connect, but after a few seconds gives up and tells me I am now offline.

I rebooted my machine, and now I can't connect to the wired network for some reason. Wireless works fine.

I'm not a total newbie, but run into some strange problems with my installation of Lucid.Everything was working fine yesterday. I shut down the laptop and powered it up this morning and had problems with network. I have two NICs (wired and wireless). Both are set to pick up IP settings from DHCP and both do, however when using wired network I can't communicate with outside world - can't even ping the default gateway (but pinging 127.0.0.1 or IP address of the NIC no problem, so stack should be OK).When on the wireless network everything works fine (otherwise I would struggle to write this post ).What is very weird though is that I have a VMWare Player installed and using Windows VM on wired network works just great!
I noticed that when you're persistent it happens that you can ping but huge chunks of traffic are lost (e.g. packet 1-10 would pass, 11-40 would be lost, 41-59 would pass and so on).I restarted Ubuntu, tried shutting down interfaces, disabling networking and nothing helped. I don't recall performing any changes (at least that I would be aware of).Can anyone suggest something?BTW. This is not DNS issue as both IP addresses and FQDNs do not work. When I refer to using a given network (wired or wireless) the other one is down with ifconfig command...

I'm new to Ubuntu - I've decided to give Ubuntu Studio a go as an alternative to Windows. However, after installing it, neither of my network cards work. I have a Intel Pro Wireless 3945ABG wireless card, and a Broadcom Netlink Gigabit Wired card. Neither work, And I'm not sure how to. I've tried searching, and have come up with the .tgz file here, but I have no idea what to do with it I'm concentrating on the wireless card for the moment, seeing as that will be the main one I use.

I am unable to connect to any network, wired or wireless. Network-manager and wicd are both gone, as in no longer installed. Please don't tell me to apt-get anything. I have no network connection. I have tried downloading packages for nm onto a usb stick only to find myself in dependency hell which ended with the impassible error "Requires installation of untrusted packages".

I'm trying to set up a wireless or wired network (wireless would be better...) to share my connection with my housemate, as well as with some devices. The only guide I found regarding this (I must admit, I didn't have much time to put into research), was dating back to 2005, and although doable, seemed somewhat confusing. Getting to the point: is there a way (maybe a standalone program, or some kind of plugin) to share a connection?

I am facing a problem with the management of my network card after installing Ubuntu 11.04 32-bit Desktop edition.
There are two Network Cards and one USB adapter which I'd like to drive:
- Ethernet controller Broadcom Corporation NetXtreme BCM5703X Gigabit Ethernet (rev 02)
- Ethernet controller Realtek Semiconductor Co., Ltd. RTL-8139/8139C/8139C+ (rev 10)
- Realtek Semiconductor Corp. RTL8187 Wireless Adapter
Actually I need the wireless adapter to connect to the AP, so both of the ethernet card should be disabled. Infact, when I try to access to the AP I must disable the eth0 card by using (sudo ifconfig eth0 down), otherwise the route assigns the default gw (192.168.1.1) to the eth0 device and the network is useless.

using Hardy Heron on a old Thinkpad T41.This is a fresh install system and I noticed it kept dropping wireless connection. After google around, seems like this is a common problem? Then I switched to wired network, and turned out the same thing happens again. Looks like doesn't matter wired or wireless, it kept dropping itself from time to time.
fter checking syslog, I found something interesting...it kept complain eth0 is invalid, then it said it found a better connection?I found that extremely weird..
Code:
Apr 30 06:24:32 support kernel: [ 961.236895] e1000: eth0: e1000_clean_tx_irq: Detected Tx Unit Hang

I've installed F10 on my laptop since few days and I'm facing an annoying networking issue: the network connection seems to work well when, suddently, it goes down for a while, and then come back.This happens with both wired and wireless (Intel PRO/ Wireless 3945ABG) connection.

I have just done a new install of the latest opensuse 32bit and for some reason I cannot connect to the internet, when I click on mange connections the vpn tag is highlighted and all the other tabs are grayed out and I cannot select them. So I can't setup a internet connection wired or wireless. I was just using Kubuntu and did not have this problem. My card is broadcom.

I just got a new laptop...Dell Vostro 3500. Took off Win put on Ubuntu...all went fine. I did all updates and app downloads using my WIRED NETWORK as wireless wasnt working. However I was more interested in setting up the new computer. Anyway so after all is installed up pops "Broadcom STA Wireless driver" Proprietary driver do you want to install. Obviously I said yes...
Well now My wireless is working great but for some reason my Wired (auto eth0) no longer works. It just says disconnected and its grayed in. I'm pretty much a newbie but did try a few things like:
apt-get update
apt-get "something" essential (thats not a command just from memory it was something like that)
However I've had no luck. This Broadcom driver seems to have knocked out my wired network.

I just installed Lucid Lynx on my Dell Vostro 1000 laptop. The problem I'm having is that my wired network card has died on me prior to installation. I'm having the hardest time finding the required files to make my Broadcom BCM4311 wireless card work without being able to download any packages from the web. If anyone knows which files I need and which order I should use to install them that would be great.

I have a wireless network (192.168.1.0) that's bridged to the Internet and a wired one (192.168.0.0) that's only local. When I am connected to both networks, Natty wants to route my Internet traffic through the wired, local-only one.
Can I make it automatically "just work", so that the right network is chosen for Internet traffic? Otherwise, what's the workaround?

I have a Mandriva linux box connected by cable to my router. When I stream audio using this box it crashes all the wireless computers on my network. There is no effect on wired computers. All but the one computer are windows (xp or vista). The affected wireless computers are not able to even find my wireless network. I have to reboot the router to get them online.

I have searched and have not found anything specific to my issue. I am currently using NDISWrapper to load the bcmwl15 driver and when it's active it works beautifully.Problem is sometimes at boot, the card doesn't "turn on" and I don't know how else to describe it. The OS does not even detect that the hardware is present. I have disabled wireless hotkey in BIOS. The only way to make the wireless card "active" is to reboot with the wiredconnection to the router. After doing that the wireless card "wakes up" and works awesome.Is there anything I can do to make sure the driver load at boot?mes I get the error that NDISWrapper is not modprobbed when I go to network configuration and if I wish to do i now? I don't know if that has anything to do with the boot sequence. Using the <modprobe ndiswrapper> command as root does nothing permanant

I remember that I did configure my desktop PC for wired and wireless connections since openSUSE 11.2, 11.3 and 11.4. Currently I have openSUSE11.4 x86_64 KDE. Today I happen to notice that the icon for NetworkManager in the taskbar has been replaced with a red X. I discovered that Network Manager only shows VPN tab, whereas Wired and Wireless tabs are greyed out. The strange thing is I still have Internet connection with the CAT5 cable being plugged in. I can still configure wired and wireless connections via YAST but I cannot fix Network Manager settings.

I have the problem with my notebook, that, after I used it at work, the network-manager always tries to autoconnect after boot. He has no cable network and so I get the message "not connected" after a while.how to tell the network-manager, not to autoconnect each time?

I'm running Squeeze and I'm looking 3 days now for a solution in some weird problem. The NetworkManager Applet shows that there isn't connection although I am connected. The icon has this small "x" and when mouseover it says "No network conncection". Moreover when left clicking it, it says
"Wired Network Device not managed"
While I was looking for the solution a came across this post by an Ubuntu developer who says:network-manager-applet displays the connectivity state of network-manager's managed interfaces not every interface. So the title "network manager says disconnected but is connected and working" is actually misleading. The interface is connected and working but not from network-manager's point of view since it is not managing the interface. Additionally, in Lucid now network-manager applet displays nothing now for non-managed interfaces so is less misleading. You can check to see whether or not an interface is managed by network-manager by using the command line too nm-tool. You'll see "State: unmanaged" for unmanaged interfaces.

Last night while setting up wired & wireless connection in openSuse 11.2 Gnome version via YAST's ifup, I got wireless but lost wired connection (interface eth0). Dmesg shows that eth0 became eth1. I cannot get eth0 back. Is there any way to remedy this situation, eg. get info from the Ubuntu partition in my triple-boot laptop, without having to re-install openSUSE?
