Ubuntu Networking :: No Wireless - Eth1 Has Disappeared?
Jan 16, 2011
My wireless suddenly no longer works either in Ubuntu 10.10 or Windows 7. Upon some investigation, I have found that my eth1 is no longer showing up as it used to.
What can I do to get my wireless back?
Right below is some current specs, while below that is an older set of specs from a while ago.
Code:
sef@sef:~$ lspci
00:00.0 Host bridge: Intel Corporation Mobile 4 Series Chipset Memory Controller Hub (rev 07)
00:02.0 VGA compatible controller: Intel Corporation Mobile 4 Series Chipset Integrated Graphics Controller (rev 07)

have a dell Inspiron 1501 with ubuntu 10.0.4 I want to rename my wireless card from eth1 to wlan0 as I use conkyrc and it will not read my wireless strength or my ssid cuz it thinks it's a ethernet card and not wireless card. I know this for a fact because peppermint os my wireless card was wlan0 and it worked just fine.

It is. I think this might be the reason why my $wireless objects don't work in Conky?

I have an older laptop, a Toshiba Satellite Pro 6100 that has a switchable internal wireless connection. It will not connect to my router. I am using the 10,04 netbook remix. When I use lshw in terminal this is what I get:
*-network
description: Wireless interface
physical id: 1
logical name: eth1
[Code].....
Should it not be identified as wlan0? I know a whole lot about Ubuntu linux because I don't. I did a clean install over XP and am using this laptop as a learning tool for linux in hopes to divorce windows completely.

I had no problems using my dell mini with ubuntu wireless UNTIL i did a direct connect into my home network to download some updates. Now the wireless connection option has disappeared and only shows a wired connection in "network". Does anyone know how to get it changed back. Terminal no longer shows an eth1 but lists eth0 as the wired connection on ifconfig.

I am using Ubuntu 10.04. I installed the Broadcom STA Wireless driver from System -> Administration ->Hardware Drivers, and it seemed to work fine, but the next time I turned on my laptop, my wireless card wasn't recognized anymore! When I went to System -> Administration -> Hardware Drivers, the driver was gone from the list! Where did it go?Update - Solution:his is hardware issue, not a b43 issue.

When the laptop boots I get a very brief message to say "wireless network available, click on icon". But it disappears in a second. I'm not clear whether my WL-140 card is in device wlan0 or wmaster0. Here's what lshw -C network says...
*-network

After installing Ubuntu Netbook Remix on my Toshiba NB505, I hoped the wireless would just work right away, but it didn't. After much searching, I found these instructions (scroll down to High Horse's response at #3), which directed me to download the Realtek Driver RTL8192SE. I followed the directions to a T and everything was working wonderfully, until a recent restart that has taken me back to square one. I think the default Ubuntu drivers may be overriding the drivers I installed and putting everything back to default (no wireless), but I'm not sure. Here's the latest output:
Code:
olamina@ubuntu:~$ sudo su

This is a Toshiba Satellite L640 and has a Broadcom BCM4313 controller and Bios version 1.9 and I'm posting by booting my Ubuntu 11.04 cd in "trial" mode which rules out hardware cause for trouble.My 11.04 install is brand new today and wireless was working perfectly immediately after install. Since then, I've shut it down and when I rebooted it I haven't been able to find any wireless connections.
I've installed the updates that were suggested after the install and also activated the two proprietary drivers that th system suggested - this might include the proprietary Broadcom wireless driver, that's the only proprietary driver suggested in the current "trial" mode and I remember there being the graphic driver and one other.I wondered if the wireless was turned off so I tried to turn it on or get it up. I typed ifup wlan0 but it said wlan0 was not configured. In production mode, when I click the wireless icon: it says wireless is enabled and offers me the option of connecting to a hidden network or setting up a new connection, but it can't see any connections even when my phone has seen the connection and automatically signed in. It can't see my home WPA2 connection or my completely open work connection.

After a few years of being a fedora user on a large network, I final decided to bite the bullet and dual-boot my home desktop (solely XP at the time) with fedora 10 on Saturday. The installation seemed to go well, but I am having a few problems, which solved themselves at one point but have come back and I have no idea why.
- I installed and re-partitioned with the install DVD, giving fedora 20GB. Having read a few guides and forum posts I wasn't surprised when the wifi and ATI graphics card didn't work. They appeared in the output of lspci, but I couldn't change the screen resolution and no wireless card was available.
- I bought a new wireless card a while ago but hadn't had time to put in so used this opportunity to do so (installed it in XP to check it worked) and when I rebooted, guess what, the resolution was what I wanted and I could see all the networks in the neighbourhood. I connected, downloaded/installed the myriad of updates together with a couple of programes through yum and went to bed a happy man.
- This morning (my router needed rebooting and after) I was back to the same as before the new wireless card, i.e. low resolution and no wifi. Having no idea what had happened, I check for loose connections, after that the resolution returned and the wifi worked but I can't see my home network.

I try to generate a server client code. What i try to do is sending video streams from eth0 and eth1 to the other server programs' eth0 and eth1. In order to do that, i decided to use SO_BINDTODEVICE. But the code is not working. Am i misunderstood the usage of SO_BINDTODEVICE.
1-Defining two ports
2-Defining two sockets
3-Assigning host ips on them

I am having issues with wifi on my Lenovo X220. What has occurred is that the network applet in the notification bar no longer shows me any wireless network options. When I click on the applet, the drop down shows me: Wired network: disconnected (greyed out), VPN connections, Enable networking (checked), Connection information (greyed out), and Edit connections. Missing is Wireless connections. This occurred "out of the blue" in the middle of using the computer (i.e. NOT just after a reboot or new driver installation, etc.)
I have noted that:
1. Wired ethernet works just fine.
2. Wireless (wifi) works when I boot into Windows 7 or into a fresh Ubuntu USB Start up disk (implying that this is a software issue, not hardware).
3. The hardware led for wifi is OFF (whereas the Bluetooth light is on.) In Windows or using a fresh ubuntu from USB, this light turns on normally.
This may be irrelevant, but the issue started yesterday when I noticed that the trackpoint scrolling that I had enabled using gpointing-device-settings was not working. I ran that app and checked the settings, which were normal. I then reset the computer, and found the trackpoint was working just fine, but I had no wifi. A few resets later, the problem was not solved.

I switched my girlfriend laptop from windows 7 to Kubuntu 9.4, then upgraded to karmic koala. I was able to, through the hardware manager, install a software modem driver, and a firmware unwrapper driver for her broadcom 4.X series wireless adapter. Whenever I attempted to install the broadcom 4.1, 4.2. ect driver itself a package update would fail, but wireless functionality still worked nonetheless. My girlfriend has a TX1000 HP laptop, similar to this one:[URL]..Product number in the bios is GA648UA#ABA System Board ID is 30BF
The wireless drivers she needs are proprietary. This worked for a while, although seemingly at random her wireless would go out, and her analog sound driver for her Nvidia chipsets would too. Usually logging out of the KDE environment and back in fixed the issue. Now wireless is completely gone; using a hard ethernet core to the router still works. Even connected to the internet, the proprietary drivers that used to be available in the hardware manager aren't there anymore. Right before the driver disappeared, I updated the system with all the latest round of updates, and installed the base package and some plugins for VLC. I don't know how to role back packages to see if an update killed the wireless, I uninstalled the VLC software but that didn't help.
Wireless is checked enabled on my taskbar, and I have checked my bios and haven't found any setting to disable the wireless adapter. Anything networking related has been enabled. At this point I am rather frustrated with the stability of Kubuntu overall and would prefer a hard solution that will permanently fix the problem.

I have a hardware device with two ethernet ports, eth0 and eth1 running Centos 5. Basically my goal is to forward packets from eth0->eth1 and eth1->eth0 as well as get a copy of these packets for analysis. If I set IP routing to do the forwarding then I won't get a copy of the packets for analysis.

I have a Linksys WPC300N v1 "Wireless-N Notebook Adapter" which uses the Broadcom 4329 chipset. Is there a way to troubleshoot and configure this card to use wl, b43, ssb? Preferrably via CLI. I have a couple years of CLI experience in Debian/derivatives (but only in my spare time ).
I have this card recognized and running adequately in Debian (and derivatives) using the 'wl' driver (sometimes supplied by debian.org, other times by broadcom.com). The one hint at a solution for this particular card/chipset I have found searching the OpenSUSE (SuSE for short?) forum points me to using ndiswrapper, which I've never used nor care to if it requires wine. I'm trying to ultimately connect to a b/g/n WPA-1 TKIP wlan.
lspci -v:
03:00.0 Network controller: Broadcom Corporation BCM43XG (rev 01)
Subsystem: Linksys Device 0058
Flags: fast devsel, IRQ 11
Memory at f4000000 (32-bit, non-prefetchable) [disabled] [size=16K]
lsmod | grep 'ssb' returns nothing (neither do 'b43' or 'wl') but 'pcmcia' returns:
pcmcia_core 41748 3 pcmcia,yenta_socket,rsrc_nonstatic
When configuring this card in Debian, I first plugged in the card which resulted in some hard disk activity but the LED was not lit. After installing the driver, the LED came on but no network. After configuring the network, it works 'adequately' (no roaming mode) using the wpa_supplicant package and is readily identified during init.
This is not mission critical by any means so I'm not in a hurry and willing to try almost anything. However, this is an old laptop so I'm even somewhat surprised that KDE4 is running as well as it is (KDE 3.5.10 runs quite well, which is more than I can say for the latest Gnome DE; xfce "screams" relatively). Dell Latitude C-610 PIII-M 1.2 GHz 512 KB cache 512 MB RAM (YaST2 reports this as a C-640 but this does not agree with the BIOS splash). The display is an ATI Radeon LY using the 'radeon' server (default). I don't do compositing here. ;-)

All rc.inet1 an rc.wireless scripts work well if a wireless extension is on wlan(x). My notebook has Intel Pro 2100 wireless adapter (the ipw2100 module). By the system the card is marked as eth1. If you have a look at rc.inet1(.conf) you see that by default an eth1 has no wireless extensions. how to set up my network.

I looked at the /etc/rc.d/rc.inet1.conf file it says something completely diff than the iwconfig. iwconfig is saying there is no wireless extensions on lo and eth1 but on eth0 all my info is there now on the conf file it says and ip address on eth2 and nothing on eth 0, or 1. does anybody know why it keeps jumping back and forth? one week its eth0 and maybe 2 months from now its eth1.

I am running Ubuntu10.04 as a Virtual Machine in virtualbox.I changed my Networking settings from NAT to Bridged Adapter and manually assigned IP addressing information for eth0 in /etc/network/interfaces. For some reason doing /etc/init.d/networking restart didn't bring up the network interface. So i replaced the new /etc/network/interfaces file with the original and rebooted. Now I have eth1 in place of eth0. Under System>Preferences>Network Connections I have Auto Ethernet and eth0. However running ifconfig shows lo and eth1.

I just upgraded to Ubuntu 10.04 LTS from 9.10 and the icon that lets me view and choose wireless networks to connect to has mysteriously disappeared. I did the whole "Add to Panel" thing and added the "Network Connections" icon to my task bar, but for all the searching through that and other things like System -> Preferences -> Startup Applications, I just can't find a solution! The Network Preferences still has the list of all the wireless networks I have connected to in the past. It still connects to my home network automatically (although I did have to delete another neighboring network from the Network Preferences list so it only has one auto connection to connect to). So where in the world did my icon go? It was so great. Left click to see all local wireless networks and to connect. Right click to turn off networking or wireless.

I'm having a strange problem. I'm using Ubuntu server 10.04 LTS and I want to setup a system with 2 network interfaces: eth0 and eth1. However eth1 does not come up at boot I have a screenshot of my /etc/network/interfaces file I don't see what is wrong. eth0 gets it's adress from DHCP eth1 gets a static adress. When i try to restart networking it quits with this message "don't seem to be have all the variables for eth1 inet" Can anyone point out what I'm doing wrong? if i do 'sudo ifconfig eth1 192.168.3.1 netmask 255.255.255.0 up' eth1 comes up

I have static eth1 defined. When I boot or restart, the networking will not start automatically - i must do it from terminal by ifup eth1.
Where can I put this command to have it autostart?

I am working on USB Connectivity between android 2.1 Host and Windows Mobiles 6.1 device...When I connect the windows mobile device to android host through USB (in RNDIS Mode), It is appearing as 'eth1' interface instead of 'usb0' interface. Why 'eth1' instead of 'usb0' ? Does behaviour of 'eth1' is same as 'usb0'?

I have a bit of a "unique" situation here. I have myself plugged into two networks - since we run two networks here at work (long story, we merged and never combined them due to two different companies) and want to block ALL internet access off eth1, and only have it off eth0. I only want traffic from 192.168.67.1-192.168.67.255 allowed on eth1, but everything allowed on eth0. Or is there a way for the internet/applications to be on eth0 instead of eth1? Would I use iptables or something?
