Ubuntu :: When Ethernet Cable Is Plugged In / It Doesnt Work

Jan 27, 2011

When the ethernet cable is plugged in, it doesnt work. I have to unplug the cable, refresh the page and let it wait for the connection, after a second or two, i plug it back in, and it works. this works only for that page, which means only that page loads.. if i try to open another site or smthing else, it doesnt work and i have to repeat the exercise for the new site..i have to unplug, refresh and let it wait for connection and plug it back in.. The same thing happens if i try to download an application.. i have to first issue the command to download, and when it says "connecting to blah blah.." i plug the cable back in and it starts downloading, it doesnt work if the cable is already plugged it..!

Debian Configuration :: Wireless Only Works When Ethernet Cable Is Plugged In?

Jul 9, 2011

I have a debian-powered NAS (Buffalo LinkStation) and I want to configure the following behaviour: When ethernet (eth0) is plugged in, connect and get a static ip address (ie. 192.168.0.11) When a wireless usb-adapter (wlan0) is plugged in, connect to a wireless router (ie. "Ankkanet") get another static ip address (192.168.0.12)

My /etc/network/interfaces :

auto lo
iface lo inet loopback
auto eth0
iface eth0 inet static

[code]....

what could be causing wireless to disconnect when ethernet cable is unplugged?

Ubuntu Networking :: Laptop Locks Hard On Login Screen If No Ethernet Cable Plugged In

Jul 15, 2011

Acer 5250-BZ475 laptop, fresh install of Ubuntu 11.04. Boots up beautifully as long as an ethernet cable is plugged in. Otherwise, I get to the login screen and have just enough time to start typing in my password before the entire system hangs hard - no mouse, no keyboard, can't even get to a terminal, nothing. Have to hard power off the machine.

It seems to be a problem with the wireless card trying to initialize, but there doesn't seem to be a bios option to disable wireless on this laptop, so I'm a bit at a loss as to how to fix this problem. By the way, wireless works fine if I boot up with a cable connected - I can see all the wireless access points in my area no problem. I just can't boot without a wired connection, which makes my laptop more or less useless when I'm away from home with it.

General :: Unable To Reach The Internet - Light On Mobo Where The Ethernet Cable Is Plugged In Is Steady Yellow

Aug 2, 2011

I used my computer this morning, but when I returned this evening, I am unable to reach the internet. Also the light on the mobo where the ethernet cable is plugged in is steady yellow.

My limited experience would tell me it is a hardware failure, but it seems so strange with nothing happening during the day. How might I best diagnose the problem?

Networking :: Ethernet Cable And Wireless Network Won't Work In Ubuntu 9.10 / Sort It?

Feb 20, 2010

I'm a new user of Ubuntu, so i'm not that familiar with this OS. My wireless network is detected but when I'm entering my 128 bits WEP key, it doesn't connect at all. I have no clue where to start troubleshooting.

Here's some of my specs if that's of any help:
Computer is a Sony Vaio laptop model VGN-SZ370P
My wireless card is from Intel Corporation 82801G (ICH7 Family) USB UHCI Controller

The ethernet cable connection used to work before, but I fooled around with some commands and now seems to be disabled...

Ubuntu Networking :: Auto Eht0 Doesn't Work - Can't Connect With Ethernet Cable?

Nov 13, 2010

I've recently bought a recycled computer for my office. The plan was to get an old cheap computer and use it to write LaTex documents but nothing else. However, I can't seem to get the thing to connect to the internet. I'm on a University network which has a funny setup but I don't think that's the problem.So here's the deal. I have tried this with 9.04, 10.04 and 10.10 and it hasn't worked. The computer recognizes the ethernet cable. If I issue the command "sudo mii-tool eth0" and get back "eth0: negotiated 100baseTx-FD, link ok". However, click on the networking logo on the top right, and click auto eth0, it tries to connect for about 30 seconds, then gives up. Unfortunately I'm pretty clueless when it comes to networking so I have no idea what to do to try to fix this.

Ubuntu / Apple :: EMac And IMac File Sharing With Ethernet Cable And Other Cable?

Oct 12, 2010

how I could file share, or make the whole Hard Drive (HDD) accessible to another computer. The two other computers I have are a Toshiba Laptop with Ethernet and USB, and a iMac Intel with Firewire, USB, and Ethernet. Putting these to use along with:

Three Ethernet Cables
Two Printer Peripheral USB Cables
The Two Computers
A 2GB Flash Drive

That is all I can think of right now. I do not want to use CDs. In a way, I would like to do a network boot. So, how do I get the whole HDD visible to the others computers (either/both) and be able to write to it? I want to put Xubuntu on it, and earse the rest of the Hard Drive. The computers getting this are the iMac G3s and the eMac G4. The eMac has 256MB RAM, 40GB HDD, and a 700MHz processor. Two iMacs have 128MB RAM, 40GB HDD, and a 600MHz Processor. The other iMac is the same as the rest but has a 500MHz processor.

Networking :: Not Getting IP When N/w Cable Plugged In

Dec 23, 2009

I am working on h/w device having linux kernel version 2.6.27 with busybox installed. I observed below problems while working on jffs2 image is flashed on the board.

1)When the board is powered-up with n/w cable is connected, it doesn't get IP address automatically, I have to use "/etc/init.d/networking restart" in init script(/etc/init.d/rcS) to get the IP address.(I am using dynamic addressing)

2)When the board is powered-up with n/w cable is unplugged and plugging-in once the device is started, I get "link up" message from the system, but still the IP is missing in eth0 interface.

I have udhcpc(v1.14.1) installed. Giving below commands manually, get the IP for device:

Code:
ifdown eth0
/etc/init.d/networking restart
but It is not pretty solution for me !

What I want is, the device should get IP address automatically once the n/w cable is plugged-in. (as we get in desktop m/c's). Am I missing some scripts or configuration parameters?

Software :: RDP Into Virtualbox When No Network Cable Is Plugged In?

Dec 15, 2010

I have a kubuntu 10.04 box and it runs virtualbox with windows 2000. For the most part, the network cable will be plugged in and i should be able to rdp into my windows 2000 install just fine, however, for testing purposes and for backup server testing, I will not have the cable plugged in all of the time.How would I rdp into that windows 2k install on the same machine if no cable is plugged into the ethernet port?I have both the kubuntu install and the windows 2k install setup with static ip's, but it is not working.

Ubuntu Multimedia :: Tevii S650 Showing Signal When No Cable Plugged In

Oct 28, 2010

I am trying to get my tevii650 usb DVB-S2 tuner working. I seem to have installed all the correct drivers as far as I can tell.

When I scan for services and then use femon to look at the signal strength femon -H, I get a signal of around 83% with 0 SNR and BER. Then if I remove the feed the signal goes UP to 97% 0SNR and BER.

I am trying to monitor signal the signal level coming down from the satellite. I don't even want to be able to tune to any of the channels. Basically I want to use the PC as a glorified signal meter and datalogger.

Ubuntu Networking :: Network Manager Replaces Default Route When Eth Cable Plugged

May 5, 2010

I have been encountering this problem, not only on 10.4, but on older versions too: I use a wifi router to connect my laptop to the Internet, but sometimes I need to connect directly to another computer to move some files over GLAN. But Ubuntu's Network manager doesn't allow me to configure the eth0 interface without specifying a gateway (no gateway = grey submit button), but when a gateway is specified, it always rewrites the default gw specified already by the active wifi connection and returns back after unplugging the eth cable.

Of course this can be solved by a few route commands, but this is unacceptable since it is needed to establish the cable connection without any further assistance from within and as well without replacing the default gw and thus breaking the Internet connection. Is there, please, any possibility how to prevent Network Manager from replacing these routes?

Ubuntu :: No Ethernet Cable - Means Frozen ?

May 24, 2011

I installed Ubuntu 11.04 on my girlfriends laptop a couple days ago...had the Ethernet cable plugged in to do the install...loaded fine the first time after the install. Unplugged the Ethernet cable when I had the wireless network set up and it froze. Restarted and it wouldn't even load the desktop. Didn't make the connection at first...thought there was something wrong with Unity. After about a day and a half worth of searching Unity problems/desktop freezing and solutions, I stumbled across this:

Quote:

Do you have a Broadcom card? You have probably noticed the desktop works when you run Ethernet but it locks up when your wireless connection is active.

You'll need to upgrade the kernel to fix the issue. 2.6.39.0 did it for me.

11.04 just runs fine now.

This solution was to update the kernel, but that didn't work for me. Now I'm stuck.

Ubuntu Networking :: Intel 82566MM "cable Not Plugged In"

Nov 5, 2010

have problems with my Intel 82566MM gigabit NIC. Using the default e1000e module. The module finds and load the nic but it doesn't recognize that i have plugged in cable or not. It always says "cable not plugged in". Using xubuntu now but same problem with regular ubuntu not that i think it matters. I tried downloading and installing e1000 from Intel but it doesn't seem to find the nic at all.

Any suggestions how to work this out? My googling says others too have had problems with this card. Couldn't find any real working solution though. Its Lenovo Thinkpad T61 laptop. Using 10.10 Maverick btw.

Ubuntu Networking :: No Connection With 75ft Ethernet Cable?

I am trying to run a cable from my wireless router over a 75ft cat6 cable to my bedroom. I don't get any connection on my end and I don't have any other ideas. I did setup a m0n0wall box just to try. I got the network led on my server to light up in my room but nothing more than that. Lastly, I tried adding a 5 port switch in my room and then connecting that to my server and nada.

Networking :: Find A MAC Of Hardware Attached Via Ethernet Cable?

Apr 19, 2011

How can I find a MAC of hardware attached via ethernet cable? I have been working nicely with an industrial scanner that is controlled by a Linux PC via an ethernet cable, but the hard drive has died I need to get it working again. The problem is that the main PCB has a Realtek RTL8019AS ethernet controller chip: [URL] which I believe is used in the most basic way possible, applied straight off-the-shelf and unconfigured. To utilise the chip ARP commands are used to assign an IP address to the chips MAC address e.g. something like:

arp -s 192.168.2.5 00-05-a4-00-a8-f8

Unfortunately the actual MAC address was lost along with the HD Th only thing I could have a reasonable guess at is that the chip will have a default subnet of 255.255.0.0 or 255.255.255.0
