Ubuntu Networking :: Intel Network Card Up/Down On Current 10.04?

May 18, 2010

I am running Lucid Lynx and have only noticed this problem in the past couple weeks. Before Lucid I ran Jaunty & Karmic on this same box, although I installed Lucid as a clean install. My problem is that up to 5 or 6 times per minute my networking card drops its connection and then has its connection re-established. I have an integrated Intel 82566DC gigabit card on an Intel Motherboard DG35EC connected to a 10/100 network and am running the 64-bit version of Lucid. I've done some considerable searching on this problem and although I've seen many references to similar problems dating back several years, I have found none that seem to have any solutions that do anything for me. I never had this problem under any prior version of Linux on this box (all prior versions were also 64-bit).

In short, this block of messages repeats in my messages log:

May 18 20:18:50 mark-desktop kernel: [10121.062129] e1000e: eth0 NIC Link is Down May 18 20:18:52 mark-desktop kernel: [10122.730873] e1000e: eth0 NIC Link is Up 100 Mbps Full Duplex, Flow Control: RX/TX May 18 20:18:52 mark-desktop kernel: [10122.730876] 0000:00:19.0: eth0: 10/100 speed: disabling TSO

Most of the time I don't even see that the connection has gone down. Sonetimes everything seems to be operating fine for a half-hour or more, although it could be dropping out and coming back really quickly all of the time. Sometimes it goes out for 10 seconds.Sometimes it goes out for many minutes and I can get networking back by killing disabling networking and then re-enabling it. It's quite annoying.

I'm sorry if I'm duplicating an existing issue on this forum, but I can't find this exact problem anywhere. Does anyone have any clever ideas about how to fix this?

Ubuntu :: Intel 82567V-2 Network Card Won't Work With 11.04?

Aug 7, 2011

My problem is similar to this one [URL] and I've already tried some of the steps, to no final resolution.The OS in question: Ubuntu 11.04 64 bitProblem hardware: Intel Ethernet 82567V-2 network card[URL]I've already installed the latest driver using the README instructions (sudo make install, etc).The network card will connect ONLY to my Linksys router but not even to my Motorola cable modem, even when it's directly connected to the modem ! I cannot get any web pages at all outside of my LAN, only my Linksys configuration page on my router.As I said above, I've already tried most of the steps in that forum post above. I'm going back to retrace my steps to see what else I can do

Ubuntu Networking :: Intel 2200BG WiFi Card Won't Connect?

Jul 25, 2010

I have an old Toshiba Satellite A30 Notepad. I've installed Ubuntu 10.04 onto it and everything but WiFi works. I've installed wicd and several other network tools but just can't get Ubuntu to let me use the WiFi connection (the option is greyed out).I know the card works because the last OS (Windows XP) used it without any problems. The card is detected, the drivers are installed and the hardware (slider) switch is set to on.I think the issue is related to the Radio Frequency Kill Switch being on but I don't know how to turn it off.The output from various commands are:

Networking :: Intel 3945ABG Card Fails To Associate With The AP

Feb 8, 2010

Have been using Arch for about one year. Everything works great until a few days ago. My wireless card couldn't connect to my router.

kernel: 2.6.32-ARCH
wireless card: Intel 3945ABG
wireless card driver/firmware: iwlwifi-3945-ucode 15.32.2.9-2

[code]....

The wireless card:

Code:

#lspci -vv
03:00.0 Network controller: Intel Corporation PRO/Wireless 3945ABG [Golan] Network Connection (rev 02)
Subsystem: Intel Corporation Device 1010
Control: I/O- Mem+ BusMaster+ SpecCycle- MemWINV- VGASnoop- ParErr- Stepping- SERR+ FastB2B- DisINTx+

[code]....

Since the card works in scanning mode, I assume it's OK. I have other devices in the house that also connect to the same AP. Everyone works except this laptop.

Ubuntu Networking :: Constant Wireless Disconnecting With Intel Based Card

May 2, 2010

This is a fresh install of Ubuntu 10.04 on a Dell XPS M1530. I'm getting very frequent disconnects to my wireless network, despite good signal. I have wicd and nm-applet running side by side, wicd doesn't work by itself and nm-applet won't get a new IP after reassociating with the AP.

Wireless connection is steady in Windows 7, so I'm guessing it's a problem with the driver.

Wifi card: 0b:00.0 Network controller: Intel Corporation PRO/Wireless 3945ABG [Golan] Network Connection (rev 02)

Ubuntu Networking :: Intel Centrino Wireless-N Card Stopped Working?

Feb 23, 2011

I have a new Thinkpad t510 laptop with an intel centrino wireless N card (no bluetooth). I installed ubuntu a couple weeks ago after I got another hard drive in the expansion bay. I have the drive partitioned into two sections, 250gb for file storage, and 250gb for the linux OS. Currently no other OS is installed on the other harddrive.

I have had everything perfect for the past couple weeks, but once i installed some updates today, my wireless fails to work now. Just some general info that you might ask me, lspci | grep Network, returns

00:19.0 Ethernet controller: Intel Corporation 82577LM Gigabit Network Connection (rev 06) 03:00.0 Network controller: Intel Corporation Centrino Wireless-N 1000 Furthermore, on the top right of my screen, my wireless is grey'd out and says no network devices available on hover.

[Code]...

Im trying to connect to my college wireless network. I have looked a thinkwiki and no one has posted any bugs. Any ideas on getting it working again?

Fedora Networking :: Intel Gigabit Card Only Connects At 100Mbps

Jan 24, 2009

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:

What I can try to bring it up to gigabit speeds?

Ubuntu Networking :: 10.04 - Upgrading Wireless Card - Intel 6300 On Sony Vaio?

Aug 11, 2010

I upgraded the wireless card in my laptop (sony VAIO CW) due to the original Atheros being incurably slow.The new card is an Intel 6300 ultimate n. In Windows 7, after installing the relevant drivers everything worked without a hitch.In my Ubuntu 10.04 installation, however, I have been unable to get it working.Initially I had the compat-wireless modules installed (linux-backports-modules-wireless-generic), as I had done so to try and get the Atheros card working better. I tried removing all of these, and that made the difference that iwconfig now (instead of nothing) listed

Code:
wlan1 IEEE 802.11abgn ESSID:off/any
Mode:Managed Access Point: Not-Associated Tx-Power=16 dBm

Ubuntu Networking :: Intel WiMAX/WiFi Link 6050 Wireless Card Not Working?

Dec 14, 2010

I'm dual booting windows 7 64 bit and Ubuntu 10.1 64 bit on my Dell Inspiron 11z with an embedded WiMAX/WiFi Link 6050 series wireless card made from Intel. I only use it for wifi, not 3g or wimax. I installed the latest driver from intellinuxwireless.org, iwlwifi-6050-ucode-41.28.5.1, but it still doesn't seem to work. I ran these terminal commands from another thread:

cd Desktop/wlwifi-6050-ucode-9.201.4.1
sudo cp iwlwifi-6050-4.ucode /lib/firmware
sudo chmod 644 /lib/firmware/iwlwifi*

[code]....

After running "sudo rmmod -f iwlagn sudo modprobe iwlagn", I get this read out for my wireless card.

*-network DISABLED
description: Wireless interface
product: WiMAX/WiFi Link 6050 Series
vendor: Intel Corporation

[code]....

In the ubuntu help section it tells me to flip a manual wifi switch to enable it, but pressing my windows wifi button, F2, doesn't appear to do anything while in ubuntu. The only experience I have working with linux is typing some terminal commands on my android phone to root it.

OpenSUSE Wireless :: Intel 3945abg Wireless Network Card Cannot Connect To Router Automatically

Apr 8, 2010

I clicked "Network Settings", and I found that the ip address was wrong, which is "192.168.1.10/24", and netmask field is empty, so I modifed the configuration file located in /etc/sysconfig/network, named ifcfg-wlan0, added one line(NETMASK= '255.255.255.0'), saved it and reboot the system. After rebooting the system, I still found the ip address is wrong and netmask field is empty, so I have to use ifup command to activate my card manually every time the system starts.

Ubuntu Networking :: Wireless Home Network Is Not Recognized By Network Card (RealTek RTL8190 Mini PCI)

Jul 12, 2010

my wireless home network is not recognized by my network card (RealTek RTL8190 mini PCI). The post was as follows: "I am using a new computer with Windows 7 , Athlon quad core 2.60 64 bit, 8GB RAM. Internet conection works fine with ethernet but ubuntu does not see my wireless network. card (RealTek RTL 8190 ID: 10ec:8190). Have searched this forum but unable to come up with a fix. I was looking for windows XP drivers to use Ndiswrapper but could not find a list of .inf files. My network is OK and works perfectly in windows and with my 2 laptops. Can anyone point me in the right direction? Additional info: install was done within Windows using WUBI to a separate partition on my HDD. I am new to this and thouroughly confused as to the procedure for installing the drivers if they are in fact available."

I am very frustrated in that I would like to use Ubuntu 10.04 but it is useless without internet connectability. I am new to linux and do not understand where to get the appropriate drivers or how to install them. I wish someone would answer this post and either give me a clue what to do or just say "give up" and uninstall ubunutu.

Fedora Networking :: Network Manager - Terminating Current Connection

Sep 19, 2009

I have installed recently the Fedora 8 in a computer and during installation it was set a static IP with the netmask and gateway. At first it worked well, but after some boots the connection begins to fail. It seems that the network-manager withdraws the static IP and tries
to get connection via DHCP. Below is the /var/log/messages file during the failed connection:

Code:

Ubuntu Networking :: 10.04 & Intel 4965 Wireless - Can't Ping The AP Or Any Other Computer On The Network

May 2, 2010

Installed Ubuntu 10.04 on my Sony UX280p with Intel 4965 wireless. Ubuntu detects the card without issues (as far as I can tell). I can see all access points in my area and select my access point and pair with it. I get a DHCP address from the AP (if ifconfig is to be believed) and iwconfig shows the ESSID of my AP but I can't ping the AP or any other computer on the network, nor can I ping the sony from any other computer on my network. Last year I had installed 9.04 on this computer and wifi worked out of the box without any issues.

Slackware :: Intel 945 And Current / Getting Blank Screen?

May 23, 2010

I upgraded one of my laptops from 13.0 to current yesterday. I has an intel graphics card:

Code:
00:02.0 VGA compatible controller: Intel Corporation Mobile 945GM/GMS, 943/940GML Express Integrated Graphics Controller (rev 03)

After all the package upgrading, removing obsolete packages, running lilo etc, I rebooted and I was really taken by surprise. Apparently, this certain intel graphics card doesn't work right with KMS. The boot process starts, I get to see the two tux twins and a few lines of boot messages, but as soon as KMS kicks in, everything goes completely blank. It doesn't crash or freeze or anything, the boot process continues, but it's all blank.

What's completely weird is that I have another laptop, which reports exactly the same graphics card, but KMS works fine there with current!

Anyway, I did some google search and I found that it's a common problem. There was a suggestion to remove any vga=... lines from lilo.conf, but that didn't help at all. Adding nomodeset to my boot options, disabled KMS, and I was able to boot to init 3, just like in 13.0. The problem was that then, it wasn't possible to launch X, because the intel driver that is included in current requires KMS to work!

So, after trying out a few different versions of the intel driver, I found that anything from 2.8.x and down wouldn't compile and that anything after and including 2.10.x require KMS. The only versions that would work are 2.9.0 and 2.9.1, which seem to have an identical effect here. They both work, but I have artifacts using my favorite mouse cursor theme, I get a black box instead of the mouse cursor. Not a big deal and choosing another theme fixed that too.

What I'm thinking is that probably more people will have the same problem and nothing is more frustrating than a completely blank screen. Maybe it would be a good idea to keep the 2.9.x versions of the driver in /extra. That and perhaps also add a note in the UPGRADE docs about adding nomodeset if you have an intel graphics card and you get a blank screen.

Ubuntu Networking :: Broadcom Corporation NetXtreme BCM5721 Network Card Randomly The Network Connection On The Server Will Stop Working?

Jan 29, 2011

I have a Broadcom Corporation NetXtreme BCM5721 network card on my server at work.Everything works fine for a few weeks, then randomly the network connection on the server will stop working. After it stops working, I will try to reconnect with the network manager, it shows a wired connection available, it shows the "connection in progress"animation, then the "connection disabled" icon.

I uninstalled the network manager and used manual configuration, but do you think the network manager was the issue? I can't have the server disconnecting randomly every few weeks with no way to know what the real problem is. Was there an issue with the network manager with 10.04?
