Ubuntu Networking :: Gigabit Card Only Works On 100 MBit
Apr 14, 2010
I have bought two Asus NX1101 gigabit cards for my kubuntu box and ubuntu server box. The cards are automatically detected as eth1. However the speed is set to 100mbit instead of 1gbit.
I noticed that both lshw and ethtool claim that the card does not support 1000mbit. So changing the speed manually with ethtool doesn't work. In windows XP the card works as it should.
From what I can see in mii-tool I should be getting 1000Mbit link but when I transfer files I only get 100mpbs?
Code: morrow:~# mii-tool eth0: no link eth1: no link eth2: negotiated 1000baseT-HD flow-control, link ok eth3: negotiated 1000baseT-HD flow-control, link ok morrow:~# lshw -C Network *-network:0 .....
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 recently swapped out my old network switch (10/100) for a Netgear GS105 gigabit switch. With the exception of my Fedora 10 laptop all the rest successfully connect at gigabit speeds. But my laptop (with an Intel Corporation 82566MM Gigabit Network Connection (rev 03)) will only connect at 100Mbps. If I look in the logs for my network card here is what I get:
0000:00:19.0: eth0: Link is Up 100 Mbps Full Duplex, Flow Control: RX/TX 0000:00:19.0: eth0: 10/100 speed: disabling TSO ADDRCONF(NETDEV_CHANGE): eth0: link becomes ready
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 installed ubuntu server 9.10. During the install the onboard 10/100 land card was automatically installed and was used for updating packages. I just put in a DGE-530T gigabit ethernet card. I can see it recognized under lspci.01:07.0 Ethernet controller: D-Link System Inc DGE-530T Gigabit Ethernet Adapter (rev 11) (rev 11). It does not show up under ifconfig. The CD came with linux drivers. The readme talked about recompiling the kernel and a whole bunch of other stuff. Google was equally confusing. What do I do?
I'm giving up trying to install Lenny as a server. The netinstall won't recognise my realtek 8139 chipset on the PCI ethernet NIC. I've googled so much i'm freakin loosing it. The install fails while getting an IP adress via DHCP. So a new networkcard is in order. Why not go for gigabit lan then. Which PCI gigabit LAN card is 100% guaranteed to work with Lenny net install cd?
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.
NIC: Intel 82574L Gigabit mobo network card Issue: After the server has been up for a random amount of time, the network connection is lost. Attaching a console and looking at ifconfig I see a large number of dropped packets and collisions.
use; Code: lspci -vxx to list the make manufacture of NIC and the device driver it is using.
In this case: Intel 82574L, e1000e Look in var/log/messages to get the version of the driver, in this case 1.0.2 Download .gz file with source code, follow instructions to install newest driver (e1000e.ko), in my case version 1.2.10. [URL]
I have a now pretty old PC, I think it is 400 Mhz Pentium II, on which I installed a Linksys WMP54G 802.11g PCI card, and on which I wanted to run Fedora 10, but I can't get the wlan card working. As I had a vague memory of having it seen working before, I reverted to Fedora 9, and it worked, at least before I made an update of it. So I took a closer look at it, and besides finding out that there is nothing wrong with my PC and the WLAN card, I also found some oddities. My feeling is that the configuration settings in Network Configuration window seems a bit unrelated to the behavior of the system. Here is a summary of what I found:
1) The WMP54G/RaLink does neither work rightly after installation of Fedora-10-i386, and nor after updating it. 2) The WMP54G/RaLink device worked rightly after installation of Fedora-9-i386, but not after updating it. 3) It seems strange to me that there is no wlan0 entry in the Network Configuration window, neither for fc9 nor for fc10. (There is an eth0 entry though.) It feels even stranger that the systems connects anyway over wireless, even though there is no wlan0 entry, both for fc9 and fc10. 4) After having manually added wlan0 in Network Configuration window, it seems strange to me that the system tries to connect via wlan0, e.g. after a restart and login even though nothing is checked in the Wireless Device Configuration window for wlan0. (I believe this oddity is valid for eth0 too). 5) For Fedora 10, I get prompted to save the network configuration even in the case nothing has been changed.
I have an auxillary laptop that I use with Fedora 9 on it. Up until now, I have been using wireless just fine with a an old Marvell card. A friend needed a wireless card, so I gave it to her because I had a spare Belkin card (PCMIA) with a RT2500 chipset. This chipset has been supported in Fedora for a long time, and it does it fact work but it will not obtain an IP address and disconnects from the Network Manager upon every attempt to connect.. I get an error that says "set bit rate" failed and I cannot get assigned an IP address from my router.
I do not use encryption. Nothing I have tried with sysconfig-network has had any affect.
iwlist scan finds the router just fine with a good signal, but will not connect.
I have a Broadcom based PCMCIA wifi card that works great on an older kernel in Debian after a friend of mine did the fwcutter business.
I just installed Backtrack 4 release version on another laptop. While this card works right out of the box the sensitivity is greatly reduced. The built in wifi card (Intel chipset) can see twice as many APs at any given time.
Now, I know that Broadcom chipsets are not the best but this card normally has fantastic sensitivity and Tx power plus an external antenna connector so I really need to get it working properly. When it's working properly under Linux or Windows it blows the competition away.
Could anybody confirm that the D-LINK DWA-556 wireless N PCI-E network card works with Lucid Lynx 64 bit? Im looking for a reliable wireless network card that if possible works out of the box on Lucid 64 bit, so far my search has lead me to the above card, If anyone has hands on experience of this card on lucid 64
I was uninstalling some programs through the package manager, then restarted. When my netbook turned back on, I had no internet connection and the WiFi icon wasn't showing in the notification area as it usually does either. Says the card is functioning properly and everything. Other devices can connect to the WiFi.I'm kind of new to Ubuntu and searched around a bit, but am at a loss. HP Mini 110Ubuntu 10.10Broadcom BCM4313Edit: Quote:$ sudo ifconfig -s
I have a dual boot system (Suse 10.0 and Windows XP Pro) in my notebook. My notebook is toshiba m358, which has a Marvell Yukon Gigabit Ethernet Network Card (Marvell 88E8072) on it. My problem is this: in Windows XP Pro, the network card works well, but in openSUSE, the light on the network card does not turn on. I believe that there is no driver for the network card. I have tried several ways to solve this problem:
1. Download Marvell 88E8072's driver from "[URL]", whose name is "install_v10.85.3.3.tar.bz2", and then install it with following commands:
Code: # tar xfvj install_v10.85.3.3.tar.bz2 # cd DriverInstall # ./install.sh .....
Code: # modprobe sk98lin # WARNING: Deprecated config file /etc/modprobe.conf, all config files belong into /etc/modprobe.d/. After I reboot the openSUSE, the light of network card is still off.
2. Follow "[URL]" to configure the Marvell 88E8072. It also does not work.
I just got Ubuntu and am new at this stuff. I have a dual boot windows 7 64 bit one and ubuntu 10.4. I booted ubuntu at startup and then tried to go online, but it says my wireless device is disabled. I tried pressing the keys on my keyboard to see if that may work, but it doesn't. I am lost and new at this.
I recently installed Ubuntu x64 on my dell studio 1535 using the windows installer (wubi).
All seems to be working fine apart from the built in wireless card, the proprietary driver (found in hardware drivers) installs and activates successfully and works perfectly. Until I shut down or restart the system. On the next boot the wireless card is 'disabled' and no longer works.
The card I have is a Broadcom Corporation BCM4312 802.11b/g
I am going to try a proper install on a second partition rather than using wubi later on but wondered if this was a commonly occuring problem?
The wireless card works as soon as the driver installs, however I am shown a "restart to activate driver" message and after restarting it's dead.
I was wondering how much resources are necessary to run OpenVPN on a router or router computer at speeds of 50 Mbit/s. (I've Googled this and have found the results to be unclear)
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.
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.

This was the best optimisation I could get, I did follow the NFS HOWTO. Copying from my PC does not exceed 120Mbits/s (System Monitor). My PC nic does not support jumbo frames. I'm looking for any assistance to improve my network speed. My PC has 4GB RAM. I copied 74GB of average sized files between 4MB to 12MB (uh ... compressed audio) and it took 155 mins using tar:
I'm building a new system with a Gigabyte E7AUM-DS2H micro-ATX motherboard. The onboard lan is a gigabit RTL 8211CL chip. The led on the port is orange when it is in gigabit mode and green if it's 100Mbps.When I power the machine on, the led is orange. After ubuntu loads, it goes to green. Oh, and it -is- connected to a gigabit switch. I don't know where in ubuntu to set it to stay in gigabit.Here's part of lspci:
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 2 10.04 machines connected through a switch, both with gigabit on board ethernet. Both machines show 1000 Mb/s connections.When I transfer large files (gig plus up to multi-gig) the maximum I get according to ftp 11472 kB/s.I did rough computer school math in my head and that seems low but I'll admit I know very little about network transfer rates.My question is what transfer rates should I expect to get between the 2?
I'm using Ubuntu Server 10.10 64 bit and am trying to get my Atheros AR81xx gigabit ethernet controller to use 1 gbps.I have 2 ethernet controllers, one's a linksys 100 mbps (which is connected to the router which goes to the internet) and the other is the Atheros gigabit controller that is connected to a Windows desktop that has an NVIDIA gigabit ethernet controller (for faster file transfers with a gigabit connection) I've ruled out that the problem is with the desktop as I plugged the windows PC into my macbook (which has a gigabit controller), and both the macbook and desktop report a gigabit connection.
I plug the windows desktop into the server and I only get 100 mbps. I am using a Cat 6 patch cable. I've tried several methods with ethtool to force it into 1 gbps mode, but none work. I've tried using a different cable. no change. I've tried making windows force a 1 gbps connection, didn't have the option to in the driver configuration. Only 10/100 configs. the commands I've tried in ethtool
Code:
ethtool -s eth0 speed 1000
Reports no error, but no effect. I've tried forcing off auto negotiation (I had a hunch it was causing the problem)
Code:
ethtool -s eth0 speed 1000 duplex full autoneg off
I get this
Code:
Cannot set new settings: Invalid argument not setting speed not setting duplex not setting autoneg
I tried each setting individually, and autoneg won't set, the others will (but not do anything)
