Debian Hardware :: Wired Ethernet Interface Not Listed On Toshiba Laptop
Jun 18, 2014
I need to share internet connection through wired-ethernet with another computer which does not have a wifi card.
However, no eth* interface shows up on ifconfig. Even more surprinsingly, neither lshw nor lspci shows anything related to wired ethernet controller/adapter:
Code: Select alllshw -C network
*-network
description: Wireless interface
product: WiFi Link 5100
vendor: Intel Corporation
physical id: 0
bus info: pci@0000:03:00.0
logical name: wlan2
[Code[ ....
Why isn't my laptop's wired ethernet not showing? I have a Toshiba Satellite PSAG8U-04001W.
The installation of Debian wasn't originally on this system: it was on an older laptop whose motherboard fried, so I rescued the hard drive as well as the Debian installation. However, I doubt this should have anything to do with lspci not even detecting the wired eth controller.

I have a generic P4 desktop computer with Debian Squeeze. Since instalation my wired ethernet connection will slowely slow down and then quit when surfing the web. Sometimes it seems worse than othertimes. If it fails I usualy can get it to come back back up by going to Network Connections and clicking on "wired connection"and them just closing the window. It will work for a bit but the conection will inevitably quit in a short time again. Interstingly it seems mostly a problem with web browsers as doing upgrades, package instalations, using SMXI and things of this sort do not seem to be a problem. I have tried both Epiphany and the Squeeze default Iceweasel with identical results. Also when using Google Earth a similar situation occurs in about 2 minuits of use. The same computer running Debian Lenny with Epiphany and WXP with the dreaded IE do not have this problem.

CPU fan apparently is not working with Debian (or Kernel, I don't know who's responsible for ACPI devices management. ).After setting up lm-sensors to show core temperatures, and running a simple "while(true);" C program, I noticed the fan doesn't turn on until the temperature reaches 80 degrees Celsius, and when it does, it runs at what appears to be full speed (VERY noisy). Also, it stays turned on at that speed even after temperature gets below 35 degrees Celsius. The only way to turn it off is to put the computer to sleep and wake it up again, but if I do the same procedure, it happens again.
I think it is related to some compatibility problem with ACPI devices because when I turn on the computer, I can't get the Fn keys to work, but after I suspend and wake it up, I can control the brightness using the Fn key and use the Play, Pause, etc. buttons. I read this has something to do with ACPI issues, the same as the fan control issues, because "try to suspend and wake up the computer" is something people usually tell to others with this problem (I assume just to confirm the diagnostic).Everything works fine on the pre-installed Windows Vista that came with the computer. It's definitely a compatibility problem.
I've read a lot in forums, even here, but I couldn't get any solution for this. I installed toshset but asks me to enable a Kernel module which I have no idea of how to load. I have no idea of how to load a Kernel module in fact.Also, I didn't want to believe, but I read there's no solution for this (at least, not one which doesn't involve a lot of knowledge on the matter).I'd like to stay with Debian, so I'm doing my last try here before installing other Linux Distro. I hope this problem is about Debian and not all Linux distros.My laptop is a Toshiba Satellite L355, Intel Pentium Dual Core T3200. I bought it in the end of 2008, so it's kind of old.

I have this wired problem with my realtek rtl8101e ethernet. It keeps on disconnecting randomly with my router. My computer is connected to D-link router via LAN cable. This problem does not occur in my windows xp os.
I have to suspend and resume my Debian os (wheezy 7.6 KDE) to get the ethernet connection up everytime it disconnects with my router.
These are my ethernet details
Code:
Select allEthernet controller: Realtek Semiconductor Co., Ltd. RTL8101E/RTL8102E PCI Express Fast Ethernet controller (rev 05)
Subsystem: Realtek Semiconductor Co., Ltd. Device 0123

Just resently I managed to activate internal bluetooth adapter. I'm not expert in command line and everything I could was done in GNOME. Same like most other systems an icon appears in panel bar whenever I used to type <modprobe omnibook ectype=14>. It took me some time to set everything with the kind help from URL... So the thing is that after fingering with some newly installed packages concerning b-tooth utilities that icon is gone and b-tooth is not active.

I want to configure multiple virtual ethernet interfaces over a single physical ethernet interface (eth0) and for each virtual interface the MAC address must be unique and the IP address must be Static.Finally all the virtual interfaces must be able to communicate both internally and externally and the traffic should be captured using wireshark.
I need to have such kind of setup to communicate devices individually using one physical ethernet device.
Because I was fiddling with few kernel modules like MACVLAN and MACVTAP and successfully enabled those modules and rebuild kernel. Using macvlan and macvtap I can configure virtual interfaces with unique mac address and static IPs but while capturing packets using wireshark interfaces behave weirdly.
For example say on HOST machine I have 1 physical interface and created 3 virtual interfaces as shown below.
Interfaces :
eth0 (physical ethernet interface)
IP: 192.168.A.A
MAC: aa:aa:aa:aa:aa:aa
[Code] ....
First from above interfaces I started pinging eth0 internally from host machine in which it worked as usually.
Second I did same externally from other machine which is connected to the same network of Host machine, and this did work as usually.
Third I pinged first virtual interface veth0 both internally and externally and this also works and after that I did check source and destination MAC address using wireshark tool-where both showed up there respective MAC address.
Now triggers the issue, where I pinged second virtual interface same like I did for first one, but this time ping was success and where as in wireshark tool the MAC address for veth0 is picked by veth1. This is where I got stuck and this issue happened for all the remaining virtual interfaces.
I couldn't see any virtual interface showing their respective MAC address, as of the remaining except the first virtual interface has been picking the first veth0 mac address.

Ethernet is not detected with the following setup:
OS: Debian Lenny
Laptop: Dell Latitude D600
Ethernet adapter: Broadcom 57xx Gigabit Integrated Controller
Wifi adapter: Broadcom BCM4309 802.11a/b/g
Have done the following troubleshooting suggestions from around the www:
LAN controller is enabled in BIOS
dmesg | grep eth0 returns nothing
lspci -v | grep -i net shows wifi adapter but no ethernet adapter
ifconfig -a does not show eth0
ifconfig eth0 up confirms ERROR while getting interface flags: No such device
Have done lsmod, but not sure what I should be looking for.
I would post lspci, dmesg or any other output, but as the adapter is not being detected, I have no network/internet connection from that laptop, have only one other Windows based (at this stage) laptop that I am using to write this message, and so would have to type out the output manually.Adapter indicators are both on when laptop is powered up. Am unsure if the ethernet adapter has somehow gone to sleep, and if so, unsure how to wake it.Perhaps the ethernet adapter is defective, but am hoping to confirm this before looking for a workaround/replacement.

I run Ubuntu 10.04 on a PackardBell laptop, with an Orange Livebox 2 providing ADSL. I am connected to the Livebox via WiFi, but I can't connect using the ethernet cable. I think that in making changes to the system some time ago I must have ruined something, but I can't work out what.

First I must say I love Ubuntu Netbook Remix. I purchased an Acus 1005HAB Eee PC last week and immediately installed UNR. The redesigned Applications menu is awesome. I've had a few bumps here and there, mainly with the internal mic (wanted to use Skype). In an attempt to get the internal mic working, I installed some of the linux-backports modules as instructed by some of the forum postings here. It seems as though installing the backports modules may have affected my network interfaces, as they now act funny after resuming from suspend. The wireless comes back, but just says "device not ready" (not worried about wireless right now). However, the wired interface won't come back at all after suspend. I must reboot the machine to get eth0 to be recognized.
I read through lots of forum posts about similar issues, but most of them had to do with the wireless interface, not the wired. I saw some posts talking about adding SUSPEND_MODULE instructions to some /etc/pam.d files, but I got the impression those were for NVidia network cards, not the internal cards present in the Eee PCs. I purged the linux-backports modules I had installed for Alsa (mic and speakers) and rebooted the machine, but still have the same problem so now I don't know if that's what caused it. Both wired and wireless were working flawlessly after resuming from a suspend when I first installed UNR, so I know it's possible!

I've been working on a koala system, trying to set it up as a wireless AP with a pair of wired interfaces. The hardware itself is a small Nvidia ION platform with a built-in NIC and a bunch of USB ports, so I decided to set it up with a single wired USB NIC and a wireless USB NIC. For wired, I settled on a TrendNet TU2-ET100. Initially, this NIC worked perfectly on with no hackery required, plugged in and off it went, assigned as eth1 on the system.
For wireless, I've tried a couple of different units, both of which required use of the compat-wireless drivers to get recognized. I'm still having problems with that, but I'll deal with that later. In building and installing the compat-wireless drivers, it appears to have messed up the included drivers for my TrendNet USB NIC. Now when I boot the box, it comes up with the following error:
And from there, the NIC won't show up any longer - no eth1 visible in ifconfig -a. Clearly, some alternate driver (usbnet?) from compat-wireless has messed up the asix driver from being able to start up. Any ideas on how to get that restored?

It was working just fine, until the other day I yanked it out. The wireless works just fine on the same router. If I login to a windows 7 instance on this dual boot laptop then the ehternet works just fine. So it's not a hardware, cable or router issue. The card even gets an ip, but I can't connect to the internet.

I've got Puppy Linux on a USB key, and yesterday, while I was on the internet with it, it hanged. I didn't know what to do, and I rebooted from the button (I now know what to do ). The problem is that, after rebooting, Puppy doesn't recognise the router. I've tried to apply the drivers that are on Puppy, but there aren't any compatible.
My router is a Xavi 7968 and my Network Card is:
NIC Fast Ethernet PCI Familia RTL 8139 from Realtek
(On Realtek's website, there isn't any driver linux-compatible)

I'm using a Toshiba Satellite A200-21T LapTop with Ubuntu 9.10
I used to have dual boot with windows Xp but i shoot windows out (Sorry bill )
In windows i was able to use bluetooth with my nokia phone.
The wireless hardware button in the laptop is on. There is no option it the bios to turn off the bluetooth, so i'm sure that the machine is booting with bluetooth on.
i run this command in terminal:
Code:
ruival@ruimadlinux:~$ cat /var/log/dmesg | grep Blue*
[ 0.380007] Bluetooth: Core ver 2.15
[ 0.380012] Bluetooth: HCI device and connection manager initialized
[ 0.380014] Bluetooth: HCI socket layer initialized

I'm stuck after a clean install of FC14 on an old Everex StepNote (Doing this for a friend). I tried Ubuntu on it first (because it's so easy) but had horrible stability issues and terminal commands wouldn't respond - however Ubuntu detected and ran the eth0 port just fine. FC14 detects my ethernet NIC, but it won't work.
Here are my details.
lspci outputs this for my NIC:
00:12:0 Ethernet controller: VIA Technologies, Inc. VT6102 [Rhine-II] (rev 7c)
Here is what I have tried so far - with no luck:
- I have toggled the networking switch on the laptop and had no luck.
- Downloaded Via's VT6102 drivers for Fedora Core, but they don't support kernel 2.6.35.*
- Run ifconfig to manually assign an IP address - which it DID take and did route add default gw as well.
- Did a ifconfig eth0 down and up as well.
After all that, I still have a "disconnected" wired connection (and yes, I did check the cable - it works just fine in my personal machine.

Just noticed that auto connection to my wired ethernet is not being established after restarts I'm making. Never recall this in the past. I do get an auto connect when I shutdown and restart. I'm using 10.04 LTS Lucid Lynx.
Also have noticed that nearly every upgrade over the past week or so is calling for restart to complete the upgrade. Can there be any unwanted problems in doing several upgrades over a period of several days before doing the restart? I'd like to think not.
As you can imagine these two issues together are causing some lost time.

I have installed Ubuntu 11.04 using Wubi through Windows 7. It seems to be working but it will not connect to my wired internet connection. It tells me there is no wired connection, when there is. I used sysinfo and its not showing any network adapter or controller. I have a board with nvidia nforce go 430, could it be a driver issue. It works fine in windows though. Tried using a wireless adapter and all is working. But why doesn't the wired ethernet connection work.

I've a server with two NIC. Sometimes the server becomes unreacheable. When this happens, I did a reboot and then it works.. but when looking at the interface status (with ifconfig command), I've notice several "errors".So, I've tried to change NIC.. but the problem occurs again.I've also changed the port on the switch.

I booted an OS from live disk. The OS boots successfully but eth0 fails to start. I checked lspci , it outputs the exact ethernet card details :(Broadcom Netextreme II BCM5716 Gigabyte ethernet)
Ifconfig -a returns only loop back interface lo and sit0. The output of dmesg | grep -i 'eth' is :"Netfront : initializing network ethernet driver"
I was also able to find the kernel module bnx2.ko. I did insmod and lsmod lists it. I am not sure what exactly is the issue or how to debug this problem. Any assistance or pointer will be helpful. Thanks for your time.
