Ubuntu Networking :: Realtek8111/8168B Ethernet / 10 4 1 Not Finding Wireless Network
Oct 9, 2010
I installled Ubuntu 10.4.1 on a brand new computer with a Realtek RTL8111/8168B PCI Express Gigabit Ethernet controller on a Foxconn G41MXE motherboard. and I have been unable to connect to wireless network. I have gone through the wireless trouble shooting guide to no avail. When i "check for device recognition" i get the following (note the is no CLAIMED UNCLAIMED ENABLED OR DISABLED)
udo lshw -C network

I have an MSI Megabook M662. Can't get my wireless working. I have "enabled" checked, but can't view any connections. I don't have wireless at home, I'm trying to make this work for free connections at the library, etc. From the Help Menu troubleshooting I tried:
mag@MSIubuntu:~$ sudo lshw -C network
[sudo] password for mag:
*-network
description: Ethernet interface
[code]...
This reports Disabled, and the advice is to check that device is on. But I just want to roam for service, I don't have my own wireless at home. I thought I might need to use ndiswrapper but I cannot locate a driver for this card info:
lspci -nn 02:00.0 Ethernet controller [0200]: Realtek Semiconductor Co., Ltd. RTL8111/8168B PCI Express Gigabit Ethernet controller [10ec:8168] (rev 01)
What should I try now?

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...

How can I find out programmatically if a cable has been removed from an ethernet connector where the interface is "up" ??? Without using ping of course.
Sidebar question, if I have two interfaces on the subnet how can I force a ping out a specific interface? Say, I have 192.168.5.14 and 192.168.5.13 and I want to throw a ping out *.13 and not *.14 ..

I'm experiencing very slow network speeds in one direction (out) on a clean install of debian.
iperf client running on laptop connecting to server with issue:

I've tried with different cables on the server, no luck. Also note that the laptop gets full speed to speedtest.net as per my internet subscription (75/75 gbit fiber), so the laptop can be ruled out as a problem since it gets more than 75X performance to the internet compared to the local server.
The main purpose of this server is to be a virtualbox host. I've set up one guest system and ran iperf between the host/guest (bridged network). It gives better numbers, still the host -> guest direction is much slower than it should be:

desktop has been running Ubuntu 10.10 just fine since December. Today, the connections menu shows nothing but "Wireless Networks: disconnected." My laptop is inches away and has a full connection.I'm not sure what diagnostic tools I have at my disposal. The one thing I've been able to do is lspci. The relevant output of sudo lspci -v | less is:
03:05.0 Network controller: RaLink RT2561/RT61 802.11g PCI
Subsystem: RaLink EW-7108PCg
Flags: bus master, slow devsel, latency 64, IRQ 20

I have a system running a very basic LTS install (10.04). Ubuntu has been setup with very little additional packages. No GUI. Once it's booted to a prompt for the first time I add the following packages,
cups cupsys ssh pi memtester nfs-common
aptitude safe-upgrade
At this time I don't have additional information on exactly what packages are installed. I did not perform the installs myself. I will update this thread when I get more details from my IT counterpart on how the system was setup.
This is used for a headless(no monitor, no keyboard) system running some custom applications.
Here are two problems.
1. If I plug into an ethernet network after I boot, the network never connects. I need to reboot with the network connected in order to get an IP. What is the service to "auto connect" to a network?
2. I have a network printer configured on lpd called myprinter. If I am connected to the network when I boot, I can print to this printer just fine using:
Code:
However, If I boot disconnected from the network and print to myprinter, the jobs obviously cannot print. They get spooled. Using 'lpstat -t' I can see that the spooled print jobs are assigned a job number and that myprinter is trying to connect. I shutdown, reconnect my ethernet network and boot up. All my printer configuration is blown away.
/etc/cups/printers.conf has been wiped out to look like this:
Code:
My 'good' printer configuration is copied to printers.conf.O
To recover from this, I need to stop cups, copy printers.conf.O to printers.conf, restart cups, and re-setup my network printer.
So, What causes my printers to get wiped out? I've repeated this on 4 systems with the same setup.

Found about this website in vector linux site,you can check before you buy if the wireless adapter works with linux or not, so I think is a good tool to check wireless adapters by manufacturer, interface or chipset, it even have links to the drivers websites,

I've been having problems trying to connect to my home network with my onboard NIC. No solution given on the forum has helped me so far.. I just can't seem to connect to the network and I have no idea how to fix it. My NIC is recognized (lsmod shows r8168 is loaded) but when I choose 'auto ethernet' nothing happens .I hope there is someone that can help me because It's a pain to not have internet access...

I installed 10.3 (after buying it a couple of years ago and letting sit on the shelf) and can't get it to configure my ethernet connection or my wireless card. Yast doesn't include a list of available cards, and the error I get in installation-network setup is that the kernel isn't present. The machine I'm installing this on is a Lenovo, in which there isn't a discrete ethernet card (it's in the motherboard), but my wireless card (a Cisco LINKSYS 802.11G) is a discrete card. Because I'm divorcing Microsoft for a number of valid reasons, I don't have Windows available on that box.

I need a simple traffic monitor for Linux, that counts the traffic in a specific wireless network because I have volume restrictions on that one.I tried it using the following iptables rule:
[code]...
iptables -m mac -A INPUT -p all --mac-source <mac-address> ! -s 10.0.0.0/8
where <mac-address> is the router's one. 10.0.0.0/8 is the local subnet. What I actually want is something like --routed-through <mac-address>. Also, is there some way to gather iptables's statistics? Or is there maybe another tool that does what I want (reliable)?

I have 2 dedicated servers, one with RTL8111/8168B (rev 02) and one with RTL8111/8168B (rev 01) both running centos 5.3, the problem is like this, all things run great on the dedicated server with NIC RTL8111/8168B (rev 02) until we run backup (cpanel backup) after the backup is finish the server lags , no high load, just lags, the server is a 8 GB ram, i7 quad core, so there is no load problem or someting like this, the second server has also cpanel on it and it has no lag but it has RTL8111/8168B (rev 01) , we think that the problem is with the RTL8111/8168B (rev 02) should we update the driver ?
Here is the output from it:
2.6.18-128.1.10.el5 x86_64 x86_64

Just today I installed opensuse 11.3 on my Compaq CQ61. Even though I am able to connect to networks (both with an ethernet cable and wireless) I don't have internet access. I have used opensuse for a very brief period in the past and I had no such problem.

I have been using Ubuntu for quite a while now (~3 years.) I recently installed 10.10 on an HP Mini 1000. The installation went fine, but now I am puzzling over how to connect to the internet. When I plug an ethernet cable into the netbook, the port light lights up, but the system does absolutely nothing. Under the connections menu on the top panel, it just says disconnected. Also, the wireless connection section states that the device is not ready because firmware is not installed. Most solutions I see for problems of this kind are to download the drivers, but I cannot do that because neither connection works.

i'm a beginner with ubuntu and i installed 11.04 yesterday (so not yet familiar with the new desktop configuration). Also, I have the french version so i'll do my best to translate the terms in english. I have a major problem: i can't connect to internet by ethernet cable or by wireless. The network icon is always empty. It doesn't detect the ethernet cable and the wireless networks around. I've tried different things i found on forums. I'v reinstalled the b43 package and rebooted. At the beginning i was only having problem with the wireless; i could connect via ethernet. But on one forum, a dude suggested the command

This week I picked up a Dell Studio Hybrid and installed CentOS on it. I originally used 5.0 since I already had the DVD and the network card wasn't recognized at all (lspci recognized it but the card didn't show up in system-config-network). I then downloaded the 5.2 DVD and installed that. The network card then showed up in system-config-network but it still didn't work. If DHCP is enabled it tells me that no link is present, and if I manually configure it, I still can't ping the router. lspci reports the following about the network card:
02:00.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL8111/8168B PCI Express Gigabit Ethernet controller (rev 02)
The driver used is r8169.
I put Fedora 10 on it and the network is working fine, but I'd rather run CentOS on this machine. Is the issue likely to be fixed with CentOS 5.3 or should I just stick with Fedora?

I just upgraded to 10.04. I had wireless connection for 1 day and now nothing. No ethernet connection either. I CAN use both wireless and ethernet using my machine on Windows.....so the connection stuff does work. Here's the output of of the commands I got from the "sticky". I can't display the output as this forum puts it all together as one continuous sentence with no line break!

I have a Toshiba Satellite L645D-S4030 running on Ubuntu 10.04. When I plug an ethernet cable into the ethernet port, simply nothing happens, and when I try to connect to my wireless network, it connects but there is no actual internet available. I'm sure the wireless works as I'm on an older model Toshiba Satellite and it connects fine (running Ubuntu 10.04 as well.) I tried to follow the procedure in the stickied thread, so when I type in these commands, here's what shows up:
Lspci
00:00.0 Host bridge: Advanced Micro Devices [AMD] RS780 Host Bridge Alternate
00:01.0 PCI bridge: Toshiba America Info Systems Device 9602
00:04.0 PCI bridge: Advanced Micro Devices [AMD] RS780 PCI to PCI bridge (PCIE port 0)

have used f14 since it came out with no problems, little niggles and whatnot have been sorted by reading these forums and googling but I'm now out of my depth.problems started when I installed f15 from disc and no ethernet or wireless was useable. Inserting wire leads to it announcing it's unplugged again a few mins later and trying to connect wireless never resolves.I thought it was a quirk and would go back to f14 for a few weeks but after re-installing that was now the same. So I tried live discs of crunchbang and debian6 -same. However puppy linux sees the ethernet fine.So my question is how do I enable ethernet and/or wireless in f15 (installed again after checking with puppy)?

I just installed Ubuntu 9.10 on my HP dv6500, and neither the wireless won't work. I don't see any drivers under System >> Administration >> Hardware Drivers, and I can't connect it to the internet any other way when I'm running Ubuntu. (I still have Vista as a dual-boot, and it works fine there). (Sorry about the title - the ethernet DOES actually work, but I can't seem to change the title of the post).

I'm trying to share my ethernet via my wireless card. It doesn't work. Here is some info:
lspci
04:00.0 Network controller: Broadcom Corporation BCM4311 802.11b/g WLAN (rev 01)
05:00.0 Ethernet controller: Broadcom Corporation NetLink BCM5787M Gigabit Ethernet PCI Express (rev 02)
lsmod
b43, mac80211, cfg80211, ssb
I've tried everything listed in these forums but every time I run
sudo iwconfig wlan0 mode master
Error for wireless request "Set Mode" (8B06) :
SET failed on device wlan0 ; Invalid argument.
I tried the STA drivers and get the same thing except the kernel module loaded is wl instead of b43. Is it even possible to set this card to master mode? I can't find jack on the net.

I have a Dell Studio 1501 Laptop and I want to bridge the wireless with the ethernet port so I can hook my xbox360 to my laptop.
I've spent the last 2 hours trying different techniques but nothing is working.
I'm running Ubuntu 9.10 so the last thing I tried was going into the network manager, clicking on wired, editing the ethernet port and allowing it to share. This did nothing.
I tried to share the connect with firestarter but that did not work either.

I tried to setup a connection as below but face some problem (probably route table setting incorrect). Hope if anyone could shed the light.Basically, I have a PC1 (.1) and PC2 (.130) connected via a PC router. PC router has 2 interfaces: wireless (.2) and ethernet (.129). PC1 connects to PC router via LAN cable/wireless interface, while PC2 connects to PC router via cable. This settings try to simulate 1 wireless connection along the path (and because PC2 is too old to support wireless interface, we need a PC router). These interfaces are all under same 172.16.130.x subnet.

I am running Ubuntu 10.10
I am using an Intel WiFi Link 4965AGN built in adapter.
When I was prompted for a system-update I clicked Update and apparently something failed an only a partial-update happened. Now my wireless/Ethernet connections do not work. I tried enabling all Network Adapters but that option is no longer available in the "Preference/Administration" tab.
Note: I cannot access the internet at all on that partition so I can't download any updates from repositories.
