Ubuntu Installation :: Network Cards Not Detected?
Feb 16, 2011
Toshiba T110 laptop, 4 meg ram, kernel 2.6.31-14; multi boot Suse / Ubuntu / Windows; Atheros AR8132 Ethernet card; Realtek RTL8191 SE wireless card.
Installed 9.10 from an old DVD lying around - everything appeared to go ok, but no networks cards - Ethernet or wireless - were detected during the install.
(Later versions do not install - problems somewhere with video card - I need to allow multi kernel selection - but this is another issue)
Does this mean that this install is toast, or can it be saved?

Does anyone have a kernel that supports Atheros network cards? I am using ASUS EEE PC netbooks and none of the kernels I have access to have drivers installed for the NICs. I am having issues when I try to build my own kernel and maybe someone has a precompiled one? Either that or if someone has a basic, step-by-step guide to building your own custom kernel. This is my first time building a kernel and I am kind of lost. This isn't actually for running Ubuntu I will be using it in an imaging program called FOG. I just need a kernel that will support these NICs so I am able to do some imaging.

I just replaced the ATI videocard by a NVIDIA GT430 videocard on my Slackware64 13.1 htpc and cant get the card to be detected by alsa so I have no sound through HDMI. Only the onboard devices are detected. Alsaconf does not see the card and the Kmix application does not see it either. Only lspci & cat /proc/asound/cards see it but seems not able to use it...I am using the stock slack64 13.1 kernel 2.6.33.4 and I've recompiled alsa from sources to version 1.0.23. What do I need to do to get this to work??aplay -l
Code:
**** List of PLAYBACK Hardware Devices ****
card 0: pcsp [pcsp], device 0: pcspeaker [pcsp]

I am trying to preseed the UBUNTU 9.04 x86 installer and everything else is okay except that for some systems, it says "No Network Interfaces found" with options as "Continue" and "Go Back". My network interface detection is set to "auto" in my preseed file. I want to remove this popup. Can someone please help with the correct line in preseed.cfg?

i installed a linux flavor (Ubuntu 10.04 LTS, Ubuntu 11.04, and then Linux Mint).. They all gave this same problem about the wired network (see the picture). The connection seems to be fine but i can't connect to internet or even to my router. Which is weird since it knows my router IP 192.168.1.79. Wasted the whole night trying to figure it out but i just can't understand why. I have a separate partition on this computer to run Win7 also and confirmed that the network connection is working.

I've installed Ubuntu Server 10.10 with two network cards. One for external, and one internal.My problem is that as soon as i activate eth1 (external), i can't access the server from the internal network (eth0)
With these settings i can't reach the internal network from inside.If i disable the gateway on eth1 and enable the gateway on eth0, it works.

Trying a minimal install with the mini.iso. I don't have a wired internet connection, only wireless from my iPhone which works fine with my full install of Ubuntu. The installer is not able to find my wireless connection stating "No Network Interfaces Detected". I did try to install yesterday in town with a friends wired internet connection and I got the same result. I'm able to get to the command line in the installer but have no idea how to start my wireless connection so the install can continue. I have searched here, and elsewhere on the net to the point of giving up.

I'm trying to do a minimal install via a USB flash drive. Everything was good until it tried to recognize my network (wired). It showed "No Network Interfaces Detected" (On Ubuntu and Debian). I wish to do a minimal install since I want to install the programs I want myself. Plus, I have a small flash drive.
I'm using an Atheros AR8151 PCI-E as my card (as shown by Windows). I also have a wireless, though I don't care much about that, wired will probably be easier. Through the command shell, I can see Ethernet Controller: Atheros Communications AR8151 v1.0 Gigabit Ethernet (rev c0). When I do plug the Ethernet cable in, I don't get the lights on during Linux installation but they do come on in Windows. If I need some additional driver, can I somehow add it to the minimal installation? I was looking through the log file and found that i82365 could not be loaded, a PCMCIA controller. I'm assuming this is separate from the NIC and interfaces between the bus and the NIC.
no idea whether it's because it couldn't find the drivers or because the controller was incorrectly identified. But I'm pretty sure this is why I can't get my network card to work.

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.

I have a desktop computer running OpenSUSE 11.2 with two network cards installed. I would like to use both cards for connecting to the internet using different networks. The setting would be the following: eth0 is the main (default) card, almost all programs should use this NIC for connecting to the internet. eth1 is used only by a few programs, which have setting for selecting which network interface to use. The two NIC's are connected to different networks, so the IP address of the NIC's, the related subnet masks and gateways are also different.
Saying short, I would like to have the two NIC's as they would be in two separate computers. I can set the IP address and subnet mask of the NIC's. The main problem is that I can only declare one gateway. How can i setup this? I do not use network manager, I configure network cards using yast, but if needed I can of course use ifconfig directly.

I'm planning to use Debian as the OS for a firewall machine, which will sit between my internet connection and the rest of my computers. Now my network is all wired, no wireless whatsoever. I'm using the onboard the motherboards cat5 socket which seems to be using the VIA rhine driver and I'm also using a 3com 100MBps card.
I can list the machine spec if you want but it's nothing special, an old Athlon 64 rig with 1gb ram and an OEM motherboard, it all seems to work ok apart from the internet doesn't' seem to work. Lenny seems to detect both cards ok and I even used the net install CD and it managed to download everything using the 3com card.
The strange thing is when I'm in Lenny, I can't seem to connect. I can ping google, but when I try and view a webpage, the browser just sits there with a while screen... Could it be that using 2 network cards is confusing Debian? Right now I've only got the modem hooked up the the 3com card, and nothing connected to the onboard network card.

So I am looking to modify my network cards MTU (for some testing purposes), and I only know how to do it it Windows (via command prompt ping command with special flags) and not in Ubuntu.
Any easy way to figure out proper MTU numbers in Ubuntu?

I have two D-Link network cards installed in my computer. The Ubuntu 10.04a2 installer seemed to recognize only one of them, though I know both are functional. I plugged a CAT5 cable in here, connected to my home network (with Internet). The installer proceeded happily, configuring DHCP and synchronizing clocks. However, when I rebooted after its completion, Ubuntu didn't recognize that I was connected to the network. I re-jiggled the RJ-45 connector, to no avail. When I run "System Testing," it does list both network cards during the Network suite, one being D-Link, and the other "James Bond" or something. So, what gives?

I just installed Debian 5.0 onto my laptop (Dell e6410) and it appears to boot and run fine, except that it does not recognize the network card (it did not do so during the installation). It also does not seem to recognize the wireless card.I have an ethernet connection, but running ifconfig displays only the local connection.I have tried adding -nomodeset and -noacpi to the boot menu, but that does not seem to change things

I have a small pc running fedora 8 with iptables and 2 network cards for routing/firewall and secondary DNS.For some time I've been alerted by the network guys that this machine was generating some alerts. The real network IP address keeps being assigned to the other interface, intended for LAN only (10.0.0.1/24).I've already changed the PC, installed a more recent operating system, replaced the 2 network cards and the problem persists. I have another pc running the same services (except DNS) in a very simillar way and no alert logs from that one.onder if it is some configuration issue on my startup firewall script.I've also installed arpwatch and I could confirm this IP and physical address issue:
Arpwatch output:
hostname: my.host.name
ip address: my.ip.address

I'm going to come right out and say I am a complete novice with Linux/SUSE. The equipment I'm having a problem with is a little web-server that was purchased by my employer that has, quite suddenly, stopped functioning. I was changing the IP address within YaST, at which point the device offered to update itself, which I saw no harm in. Post-update, however, I was unable to so much as ping the device.
I tried "ifconfig eth0": "Error fetching interface information: Device not found." I went into network settings via YaST and found that there are two cards now listed as: RTL8111/8168B PCI Express Gigabit Ethernet controller Both IP addresses are "Not configured". The information pane, for both cards, cites:
RTL8111/8168B PCI Express Gigabit Ethernet controllerBusID : 0000:02:00.0 Unable to configure the network card because the kernel device (eth0, wlan0) is not present. This is mostly caused by missing firmware (for wlan devices). See dmesg output for details. The only difference in either of the cards is the BusID (0000:02:00.0 and 0000:03.00.0)
I can neither edit nor delete either of these cards. As I mentioned, I am a total Linux novice, and am at a total loss for what to do next, or even how to find critical information about the system itself. I know enough to check dmesg, but not enough to have any clue what to look for in the output.

I have a Proliant 7000 with 4 interfaces across 2 cards - 3 intel 10/100Tx and 1 intel 100FX. During install it detected the 3 tx interfaces - but couldnt see the network - post install the network devices were no longer there, their devices missing from /dev/.
Neither google nor a forum search have been particularly edifying, is this a known issue with any cards? If so is there a known fix? ifconfig gives me information for loopback only as expected.

I've got two NICs connected to two different routers, and on different subnets of course. Each is set for static IP. But somehow I must have mixed up the connections at some point, so the NICs don't always have the IP addresses I expect. I think there may also be a mixup with different ways of setting the network addresses. When I click the Network Icon on the Desktop, I see that each NIC has both addresses as options. The /etc/network/interfaces file has some information about eth0, but all commented out, so there must be another place the addresses get set. And I just discovered that eth0 and eth1 aren't physical but virtual. I guess eth0 is the first one that is set.

I'm new to Ubuntu - I've decided to give Ubuntu Studio a go as an alternative to Windows. However, after installing it, neither of my network cards work. I have a Intel Pro Wireless 3945ABG wireless card, and a Broadcom Netlink Gigabit Wired card. Neither work, And I'm not sure how to. I've tried searching, and have come up with the .tgz file here, but I have no idea what to do with it I'm concentrating on the wireless card for the moment, seeing as that will be the main one I use.

I'm running xubuntu 10.04 LTS (upgraded from 8.04 LTS) on an old low power sempron machine as an always on 'internet machine' i.e. it does all my downloading email etc. and up until yesterday it has always performed flawlessly. Yesterday wasn't its fault, it was a BTI network problem that took out my internet service but while talking to tech support I realized that this machine has lost all ways to control the network cards. Network-manager and network-manager-gnome are installed according to synaptic but they have no menu or notification appearance. I've tried reinstalling them to no avail.

I've got two network card interfaces on my computer, one wireless and one wired. The wireless card is connected to the Internet and the wired is connected to the LAN. When only the wireless card is active, Internet works. As soon as i enable the second wired card, Internet stops working. And it seems like Ubuntu chooses the wired card for Internet as soon as it's enabled.
Are there any ways to solve this? So my Ubuntu box always chooses the wireless card for Internet traffic and let me use the wired device for LAN only?
