CentOS 5 Networking :: Broadcom BCM5700 Gigabit Not Present In 5.3
Apr 22, 2009
I just kickstarted this box - I used eth0 and had no issues. After booting - eth0 is not available/present. This was not an issue in 5.2. This is a dell 4600 - both the 100mb intel and gig broadcom are onboard. I am about to try a different kernel. This is not a show stopper - it's plugged into 100m switch and I can just use eth1 - but I am curious as to what is different and why this no longer works.
[root@localhost ~]# ifup eth0
tg3 device eth0 does not seem to be present, delaying initialization.
[root@localhost ~]# lspci

I am using fedora core 2. I used the oldest version of fedora just because im running only 1 system, my specification is: HP compaq PC,pentuim4, 512mb memory, 40gig hdd, Intel board. I have two units same spec..windows xp and the other one is fedora 2. The windows xp normally detect the lan card, but when I try to fedora2, I try to active it and seems no lan card detecting,. How to detect broadcom nextreme gigabit ethernet to my fedora 2 OS???

Using the onboard gigabit ethernet interface on an Asus M2N-CM DVI motherboard (nVidia chipset) with CentOS 5.2 the ethtool utility recognises that the NIC is capable of gigabit:
# ethtool eth0
Settings for eth0:
Supported ports: [ MII ]
Supported link modes: 10baseT/Half 10baseT/Full

I am running CentOS 5.3.The NIC on my motherboard does not support gigabit, so I bought a gigabit network card. I installed the network card and configured it via system-config-network. Everything seems to work fine as long as I keep a cable plugged into the original NIC. The original NIC works just fine if it is the only one with a network connection, but as soon as I uplug the original NIC I can no longer ping nor connect to the server via the gigabit NIC.
The original NIC is eth0, the new NIC is eth1. Is there something I need to do to tell the system that eth0 is not required or something? I've never encountered an issue like this before...

I have been trawling the web looking to see how to get my broadcom nic working on my Dell optiplex 380 with fedora 12. Basically it shows up when I run lspci but no where else, unfortunately I have no linux experience. Other things that I have tried were to check the blacklist driver file, which had no reference to the nic.

I am looking for a gigabit network card for my centos 5.4 server. I am looking for something known to work well with linux. I have been on the bestbuy site and I found a DLink (DGE-530T) card with support for linux from the vendor but after reading feedback from users with that card I am not so sure it is linux friendly. I am now thinking of buying online.

I have a Netgear GA311 PCI Gigabit Adapter. Any chance it might work with CentOS? It is not one of the cards listed when I do "NEW" Ethernet Adapter from the System Network menu. Maybe there is compatible choice?

I've just set up a PC with CentOS 5.3 runing on near identical hardware to an existing 5.2 machine. Motherboard is Asus M2A-VM which I discover by chance generally works very well with CentOS. Ethernet is on board Nvidia.The older machine just did run gigabit speed without any intervention at all, rather to my surprise. The newer machine insists on running at 100 Mbit which is annoying as it is connected to a NAS through a gigabit dumb switch.
The obvious difference between the two is that ethtool on the older machine says that supported ports are TP, and so the port is TP. Whereas the newer machine says that supported ports are TP or MII and insists on running MII. I cannot change this with ethtool -s eth0 port tp. Perhaps not too surprisingly, mii-tool says that the supported speeds range up to 100 Mbit.

I have added a new network card on my Cent OS machine. This is a RTL-8139/8139C/8139C+ card. When the machine boots or I start the network it displays "eth1 does not seem to be present,delaying initialization."I have gone through different posts on the forum with similar problems and have posted output of some of the commandsOutput of lspci is

Ethernet card works, but Wireless card activation fails at bootup time. It also fails if I try it again from the Network Configuration UI.
I have provided some output I got from initial exploration.
I upgraded to a recent version of the 2.6 kernel.
uname -a: Linux localhost.localdomain 2.6.28.7 #1 SMP Sat Mar 14 19:04:11 PDT 2009 i686 i686 i386 GNU/Linux
I have installed the correct firmware hopefully.
cd /lib/firmware ls
Output is:
I do have the bcm* files for firmware.
output of lspci is:
Last two lines show the that Wireless card BCM4312 is visible.

I've installed Centos 5.4 _AMD64 on my PC, everything is ok except I can't connect to internet. I can see my hardware in the network manager I also have eth0 and wlan0 but I can't activate them. for eth0 an error of " No cable present" and wlan0 something about the ip I don't have a cable and I used to connect through wireless My wireless is PCI Ralink and I had the same situation with Debian and I think I needed to download extra packages to get it working. I am writing from windows vista now ,So please could you provide me with the packages and steps to get wireless working through offline process because I don't have a cable.

I have installed CentOS 5 just downloaded yesterday on a Dell D620. Everything but the wireless card works. So I found this article:
http://wiki.centos.org/HowTos/Laptops/Wireless/Broadcom
and followed it step by step and was able to complete all of the tasks. The problem is that obviously it still won't start. It is not even recognized as an adapter but when I run lspci -v it is there sure enough. When I look under the networking GUI it is listed there but it has no MAC assigned to it. Please let me know what command output you need to see and I'll get here asap. I have searched this forum and other sites and nothing so far has worked.

I figured I'd rather do a netinstall for Debian, but it cannot find my network card. This has been the issue for Ubuntu as well. I did find this, but I haven't installed Debian yet: [URL] .... Not to mention it's 5 years old, and the links are obviously dead. I'm somewhat inexperienced with Linux in general, and I've searched for incorporating driver modules into the install but couldn't figure it out.
Where can I find the driver, and how can I incorporate it into the install? I wanted to do the netinstall to have Debian as minimal as possible.

I have spent them with Fedora and liked it a lot. Today I decided to install CentOS as this looks like something I would like to be using in the future. However a problem I could not solve came right at me after the first boot.
I have one eth0 device which is onboard lan and that was correctly recognised and activated. The second device is F5D5055 Belking USB Gigabit ethernet adapter. There was no problem with it whatsoever under Fedora. According to all the info it should be automatically recognised on kernel 2.6.14 and later. However when I plug it into the USB port, I can see its correct name in the device manager but it is not recognised as a network device. I have configured my Fedora as a firewall/router for my lan and definitely want to use that interface.
Hopefully without needing to do anything in the realm of compiling kernel, cause that is where my half a day long attempt to fix the problem left me.

Actually, the title I was looking for was Belkin Gigabit Ethernet ExpressCard not seen on Dell Precision M6500 with CentOS 5.5 _when system boots with no link on this card_. When I boot this system with a cable connected to the Ethernet port, the card shows up (dmesg, lspci 0e:00.0 and ifconfig). When I boot it with nothing connected, it's like it doesn't exist. I know I could make it work with a loopback plugged in at all times, but am looking for a more graceful solution. Here are messages logs from when it's recognized

Update: Should have been a little clearer - this card has the Marvell Yukon chipset. I'm trying to identify the part number without ripping out the casing.

I'm running a wired gigabit card using the atl1c driver. It works fine, but I don't get gigabit, only 100 Mbps. I have a gigabit switch and other Ubuntu machines on my network are gigabit. Is there any way this could be a software/configuration issue, or is the only likely explanation that my wires are of sub-par quality somewhere?

I recently did a clean install of Ubuntu 10.04 on my machine. It previously had windows 7 on it and everything worked flawlessly. Now the gigabit LAN connection only connects at 10Mb/s under Ubuntu. I installed a virtual machine with windows 7 and there it connects at 1Gb/s.

My kernal version is 2.6.32.10-90.fc12.i686.PAE
I'm running Fedora 12.
It auto-detected the card, but it's only operating at 100mb/s. It's connected to a gigabit switch. The driver auto-installed for the card is r8169. How do i get it up to the speed is should be at? Its kinda why i bought it...

We have a Linux box which acts a a file server. Currently, files and directories are exported using NFS.At the moment, we are a bit concern on its data transfer performance. FYI, we are using a embedded Gigabit Ethernet port on the file server. We ran a few simple write tests between NFS client (also utilizes GigE port) and the NFS server. In these tests, both NFS server and client are both connected directly to each other with a Cat5E cable. Unfortunately, the write/transfer speed results are not as per our expectation. It scores roughly about 11-12MByte/s, where as theoretically Gigabit Ethernet transfer rate is able to reach up to approximately 120MByte/s.I wouldn't expect to reach the theoretical max transfer rate (it would be great if we can , but I would appreciate if you guys can share with us in terms of the following :
1) What's the practical max data transfer rate which you guys managed to observe in a normal Gigabit based connection? What about jumbo frames configuration?
2) Is there any additional tuning/configuration we need to do within the OS to reach those practical max data transfer rate figure?
3) Does PCI-e / system bus plays a role in achieving this speed? For example, we are using the embedded GigE port and we heard some people says embedded ports are actually sharing the system bus and resources with other devices, which might adds into performance issue. Correct me if I'm wrong.
4) Does converting to Cat6 cabling will guarantee an increase in the data transfer performance?
5) In the future (once we are clear on how much single GigE transfer rate we can go) , we are looking into doing bonding since that the NFS server's shared directory/volume read-write speed is way much higher (i.e 400-600MByte/s). Will bonding allow us to achieve higher NFS read/write speed? What are the bonding modes best used for this purposes? Appreciate if anybody who has experience in doing bonding for NFS can share their experience.

I'm running CentOS 5.2 on an ASUS M2NPV-VM motherboard. This motherboard includes an NVIDIA nForce 430 built-in Gigabit MAC (network interface). I've also installed a second PCI network interface card (NC100 Network Everywhere Fast Ethernet 10/100). The PCI-based card was configured as eth0, while the built-in NIC was configured as eth1. The machine is used as my firewall/router, so eth0 is my internal interface, while eth1 is my external interface. I've had some intermittent problems with the built-in (eth1) NIC. When booting the machine and it attempts to bring up the interface, I get the following message: forcedeth device eth1 does not seem to be present, delaying initialization From that time forward, there is no eth1, and so no external network, etc. If I try running /etc/sysconfig/network-scripts/ifup eth1 (from that directory), it results in the same error.
Originally, I was getting this error when installing the operating system on the machine. At that time, I was using a 75' ethernet cable (as I was working on the machine in my office, and the external ethernet jack was in another part of the house). As soon as I moved the machine to its permanent location (which is within 2 feet of the ethernet jack), the problem went away. However, I just updated the kernel (via yum) from 2.6.18-92.1.22.el5 to 2.6.18-128.1.6.el5, and now it fails 9 out of 10 times. I'm not even sure what I can do to debug this. I'm assuming there is some kind of timing problem with the initialization. Is there a configuration parameter I can set to allow more time for the initialization to do what it needs to do, to prevent this error?

I recently upgraded a server's networking card to a Gigabit NIC, and got a hold of a Gigabit switch (Here's a link) in the hopes of increasing my network performance - however, I'm getting around 10 MB/s throughput now, which is exactly what I used to get with the old 10/100 switch & NIC. The new switch recognizes both computers as Gigabit (the other machine has always had a Gigabit NIC), and both computers say they're gigabit - I've found various sites around the interwebz recommending tweaking some TCP/IP buffer settings, which I have tried to no avail. I also saw that hard drive speed is usually the limiting factor. According to "hdmarp -t", the server HDD (definitely the slower of the two) is:
Code:
Timing buffered disk reads: 226 MB in 3.00 seconds = 75.26 MB/sec
So that's obviously not my issue. The cabling is CAT6 - I ran it myself, but if I'd mis-wired the end connections, wouldn't it just not work at all? I admit, I bought cheap NIC's (I'm not going for like 124.9 MB/s throughput here..), and I didn't expect them to be stellar, but I certainly expected the speeds to improve. I'm moving files from a server running Ubuntu 9.04 to a Windows machine - I've tried both my Samba shares on the server and an SFTP transfer: they both have about the same throughput.
