Debian Hardware :: Realtek RTL8101E Wired Ethernet Random Disconnection
Aug 23, 2014
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

I'm trying to configure the following network card to work with a 1000Mbps switch:
Code:

I think the problem is the network card module. When I run
ethtool eth0 nothing of 100Mbps is showed:

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.

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:

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 no internet connection. I am running dual boot windows XP and ubuntu. The card works fine in windows, but doesn't work at all in Ubuntu. This is the card I am using Realtek rtl8139/810x Family Fast Ethernet Nic. I am using Ubuntu 8.10, codename intrepid. I hate windows because of the viruses I contract everyday, so I decided to use Ubuntu, but this does no good without networking. so I can get online. What I do now? It is an onboard LAN card, cable is plugged in a green light is on, ubuntu just doesn't recognize it.

I am using DELL VOSTRO 1510 laptop , it has realtek r8169 ethernet card, i installed RHEL 5 in my laptop , i checked for the driver cd provided by DELL, they given one source rpm and two other rpm for ethernet card, i tried to install them through "rpm -ivh (path)/realtek-r8169 (full name).rpm " but it asking about dependency . i tried it by using yum also but still its not working.
also i tried to create binary rpm through source rpm, but it only generating spec not binary rpm, when i am using " rpmbuilt -ba (spec file) " its showing command not found error. RHEL5 have ethernet driver for realtek-8129 in their list but not for realtek-8169, i checked it in system-config-network window, now what to do, how do i install this rpm , i want to access net through RHEL 5.

my Ethernet card stopped responding a few days after installing Ralink Wireless Card Driver for Linux. I have tried installing the drivers from Realtek's site, but it fails. I also have tried reinstalling the network manager, and that still didn't help any. I have also tried looking online for any post or blog that could help, but that also turned up nothing. The Computer is a new 2010 / 2011 (bought it on new years eve) HP Pavilion desktop that came with windows preinstalled.

There seems to be some trouble with 8139too not working in a previous post. Has anyone found a solution to this? ubuntu version 2.6.24 (Hardy Heron?). Followed all known possibilities but information is all mostly out of date. module 8139too.ok? does not load. Following makefile on 8139too.c supplied, after altering to suit my version, comes up with 3 pages of errors?. ifconfig shows nothing for eth0like the last person markjuggles i have hit a brick wall here. Am I wasting my time?

I just performed a fresh install of Suse 11.4. It worked great except that the network communication would cut in and out intermittently. I managed to solve the problem posting it here for other users and for future suse releases. I will give the hardware I am running, the symptoms and the fix:
Hardware
=======
Motherboard: Gigabyte GA-H67MA-UD2H-B3
Ethernet controller: Realtek RTL8111E
Default module: r8169 (run lsmod to see loaded modules)
[Code].....
1) First make sure that linux kernel source is installed in your system (yast software management)
2) ensure that gcc is installed (yast software management)
3) Download the latest linux driver for RTL8111E from the realtek website The one that I am running is the 8168 driver version 8.024.00
4) unzip the tarball (creates a directory called "r8168-x.xxx.xx")
5) As root run the autorun.sh from inside the newly created "r8168-x.xxx.xx" directory

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.

I have several systems experiencing this issue, but the "worst case" system at the moment is a system where there are 2 dual-port PCI-X e1000 cards, and two on-board e1000e PCI-express card.What happens is maddening. If the /etc/sysconfig/hwconf is removed, and kudzu is not run, and the 6 interfaces each have a corresponding script:
/etc/sysconfig/network-script/ifcfg-eth0
/etc/sysconfig/network-script/ifcfg-eth1
/etc/sysconfig/network-script/ifcfg-eth2[code]...
Now what happens defies explanation. The only way I can be sure to make the e1000e first-listed-in-pci-order e1000e device always eth0 is to remake the initrd and add e1000e to the initrd.If I do not do that, eth0 might be the onboard night, it can also be the first port on either of the dual port cards.So eth0, eth2 and eth4 all take turns being eth0. This was not an issue in the EL-5.1 timeframe. This is certainly new to the EL-5.2 timeframe and thus far is not possible to control because the system does not load eth0's driver alias in order, and the enumeration of the PCI devices causes what seems to be random labeling of the first interface.
This is a particular problem in that identical hardware systems will come up with different eth0 interfaces , and on a single system, without the /etc/sysconfig/hwconf (which calls "eth0" something different from what was originally in the /etc/sysconfig/network-scripts/ifcfg-eth0 HWADDR directive).I need as little auto-magic as possible, I can live with PCI-bus order and driver load order is the order ethernet devices appear in, I cannot use the software in a state where what is "eth0" is randomly determined and the only way I can nail it down is to run kudzu, generate a hwconf AND brand the network interfaces in the network-scripts with HWADDR. I've been using EL since 6.2 and this is the first time I've ever encountered a situation where the enumeration rules (which are ancient at this point) over-ridden by something.
Version-Release number of selected component (if applicable): EL-5.2 series.The random enumeration of PCI devices and the subsequent assigning of eth0 to a random NIC is not on every reboot, and does not seem tied to a power off scenario vs a simple reset or warm reboot. Over the course of 0 reboots , eth0 should have moved between 2-3 times.Packages that seem relevant.

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 have installed Ubuntu 9.04
uname -r
2.6.28-11-generic
Checked cable/network with 386Box running Ubuntu 8.04 all OK. Could not get Realtek 8168 on mother board to work on Gigabyte H55M-S2H motherboard. I tried to install r8168 driver but no luck ... so I bought another Linux compatible card which turned out to be a RTL8139c (eth1) and the driver I am using on this is card is 8139too.
[Code]....
My preference would be to get the motherboard ethernet working but perhaps the card may be easier to get working. Anyway after searching the net for ideas and trying different things I've just about given up. I have reinstalled Ubuntu today so eth0 is back to using the r8169 driver. I'm no expert so my attempts at following other recipies have so far failed. From what I have read the 8139too driver should have worked with the RTL8139C chip so I have run out of ideas. I must be doing something wrong.

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 acquired an older hp compaq presario computer version 6310us, and initially installed mint, followed by Ubuntu 9.04. Neither one recognized the onboard ethernet port. I checked the bios, and LAN is enabled. It is also enabled in the drop down menu from the toolbar on the desktop. The cable works fine on other computers, and the light on the ethernet port flashes like it does when the cable is connected. I'm new to linux, so not sure what to do to get the connection working.

I recently did some troubleshooting on a USB wireless dongle hooked up to my Mint distro. I need the USB wireless to access a home DSL wireless modem out to the Internet. The wireless DSL is on 192.168.0.1
I also have a 10/100 ethernet NIC in the computer, for non-wireless connections. The wired ethernet is all 192.168.1.1. I noticed in /var/log/syslog that there are numerous "DHCPDISCOVER on eth0 to 255.255.255.255 port 67" messages.
Since eth0 has a hard-coded IP, I dunno why DHCP is trying deal with it. Can I turn off DHCP activity against eth0? How to do that?
