Intel Ethernet Connection I217-LM (WinPE drivers)

$

0

Hi everyone,

 

We purchased a few DELL Optiplex 9020s that came with an Intel Ethernet Connection I217-LM ethernet controller, and I've been unable to find the correct WinPE x64 drivers for this adapter.

From the Download Center I found what I thought were the correct drivers. In the EXE, I found some WinPE drivers, but apparently these aren't it as I'm not able to connect to my network when I boot up using WinPE.

 

Can anyone point me in the right direction to get the correct drivers please?

 

Thanks!


Option ROM Shadow RAM Allocation error for Intel X520

Hi,

 

I have recently bought X520 DP 10Gb DA/SFP+ ServerAdapter - Kit to go into Dell PowerEdge R210 II, however, this error message pops up after BIOS initialization and before OS start:

 

"Plug and play Configuration Error: Option ROM Shadow RAM Allocation error."

 

Although it can be skipped with key press, I would rather not have this error at all.

Could you please help me resolve this issue?

 

Thank you.

Martin

Problem with Intel 82577LM Gigabit Network Adapter driver

$

Hi,

 

I am recently using a new system which is a Lenovo T410 with model number 2537LE3.

I noticed that whenever I am playing musics files from a USB flash drive which surfing the internet,

it causes a blue screen sometimes with error message something like "IRQL_NOT_EQUAL_OR_LESS" with file "e1k62x64.sys".

The incident happens when I press I press enter when finished typing address or clicked link in webpage in Internet Explorer.

I did a quick search on the file and found that it is from the ethernet card driver.

So I suspected that when there is simultaneous usage in USB and Ethernet, then the blue screen will most likely occurs.

 

Hope somebody will help me to solve this problem.

 

Running on system:

Lenovo Lenovo T410 2537LE3

BIOS version: 6IET68WW (1.28)

Windows 7 Enterprise x64 with latest updates

Ethernet driver version: 11.6.92.0

 

Thanks.

Intel x540-T2 adapter + ESXi 5.5 = Poor Transmit performance

$
0
0

I found an issue and I've narrowed it down to the Intel driver.

 

Just to show the work I've put into this:

- I used iperf to test the bandwidth on all server types (Physical Linux install and inside a VM)

- I have an existing VMware support ticket and we've worked it down to the driver.

- I tested the issue with three different x540-T2 adapters and a x520-DA2 adapter.

 

Problem: When a server with the intel x540-T2 adapter is connected at 10Gbps and tries to transmit to another server that is connected at 1Gbps, All flows out of the 10Gbps adapter drops to a max of 1Gbps until the 1Gbps flows stop.

Let me clarify a bit:

 

Server A has an Intel x540-T2 adapter and is connected at 10Gbps.

Server B has an Intel x540-T2 adapter and is connected at 10Gbps.

Server C has a HP Server adapter and is connected at 1Gbps.

 

I start a Transmit flow from Server A to Server B and I see the iperf session reach full line rate (10Gbps)

I start a concurrent iperf flow From server A to Server C.

My expectation is that Server A will continue to transmit at 10Gbps (total), Server B will drop down 1Gbps to (8-9Gbps) to allow bandwidth for the 1Gbps flow to Server C.

BUT, this does not happen.

Server A will flop down to 1.5Gbps transmit and Server B and Server C will now receive 500-700Mbps until the flow to Server C stops then the flow from Server A to Server B goes back to 10Gbps.

 

Driver data:

If I use driver version 3.7.13.7  this problem does not exist!  Everything works as expected and Server A continues to transmit at 10Gbps while Server B drops to 8Gbps+ and Server C receives at a full 1Gbps.

If I Update to any version after that, it has the transmit flop.

Driver Version 3.7.13.7 is the default driver used in the ESXi 5.5 build 1331820 install ISO.

 

Newer version tested: (these are listed as compatible with ESXi 5.5 on the VMware compatibility guide)

3.15.1.8

3.18.7

3.19.1

 

Some extra info from ESXi cli:

Things to note here are the VID and DID are still being detected correctly as 8086 and 1528.

Any thoughts or questions?

I have a ton of screen shots if needed to prove the case.

Hi, I have recently bought a i350-T4 NIC, and flash the iscsi boot agent into it (18.8 version)

 

After reboot , the rom said   "error : no iscsi boot port available" and don't have the ctrl +d to do configuration.

search on the internet but cannot find any information about this problem.

 

i tried to use the intel CT adapter before and don't have this problem.

just press ctrl+ D to configure and connect to the iscsi target.

 

Could you please help me resolve this issue?

Thanks

I'm not sure if this is good category. If not- im sorry.

Hi,

Couple days ago i just bought a new computer (Asrock z87 extreme3, intel i5-4670k...). So i buit it by myself, everything went alright, settings, then i installed windows 7 x64. So then was time for drivers which i installed from CD, i was really happy, until i plug in rj-45 into. Connection is limited to 2 Mbps download and 0.03 Mbps upload, which i have connection 30 mbps / 3Mbps. Router is Linksys wrt54GL which have nothing to do, becouse when i unplug cable and plug into my laptop (hp g62-b45ew Win 7 x86) i have connection 30/3 Mbps.

 

I was using drivers from attached disc, so i download the newest from asrock site. I remove old drivers, install new, and nothing have change. I also download the newest drivers from intel site ( its internet adapter intel ethernet connection I217-V)- nothing have change.

 

What should i do ? Is it becouse im using win7 instead of win8 ? I really don't want to change os and make format.

 

Here are prove:

1. Cable in laptop:

2. The same cable, on the same settings on new computer:

Intel 82579LM Gigabit Ethernet - UDP Packet Loss

$
0

I have a software application that runs on a laptop running Windows 7 SP1 which receives data at around 100Mbps via a UDP stream over a 1GbE connection.  I've run the software on multiple laptops successfully in the past (older network adapters - e.g. 82577LM) .  Recently I installed the software on a newer model laptop which has a 82579LM network adapter.  When running the software on the laptop with the 82579LM adapter.  With the 82579LM adapter I'm seeing approximately one lost packet every 25K-60K packets.

 

1.  I'm running the version 16.7 (latest) of the Intel Network Drivers

2.  Windows 7 - SP1 + latest updates

3.  I've observed the same behavior on multiple laptop models by different vendors which contain the 82579LM adapter.

 

Searching the Internet I've seen some postings of issues under Linux complaining about similar 82579LM adapter issues:

http://www.mail-archive.com/e1000-devel@lists.sourceforge.net/msg04765.html

 

And some more here:

https://bugs.launchpad.net/ubuntu/natty/+source/linux/+bug/870127

 

Since this is running under Windows 7 SP1 we obviously have different drivers but I'm wondering if the issue is related.  Any ideas for things I could try to fix the issue?

 

Thanks,

Ryan

Unable to PXE boot guest using SR-IOV VFs

$

Hello,

 

Config-centric info:

Using HP BL460C-G8 and 560FLB (82599 based) NIC.  Host and guest OS is RHEL6.4 (latest - 2.6.32-358.2.1.el6.x86_64). Guest is defined SRIOV interfaces, but when booting, the bios doesn't appear to see any NICs  and hence does not pxe boot (seen by examining the BIOS (seabios) output in the console).  BTW, we are using libvirt and KVM.

 

I believe I need to create an optional ROM to load into libvirt, but when trying to build for ipxe, it fails.  gpxe which ships with RH (latest - gpxe-roms-qemu-0.9.7-6.9.el6.noarch) has a option ROM (e1000-0x100e.rom), but it doesn't help.

 

Thanks!

Shawn

Operating system: Windows 7 SP1 x64.

Hardware: Hp Elite 8300 CMT Desktop with Integrated Intel® 82579LM GbE Network Connection (supporting vPro remote management technologies).

 

The Question?

Teaming can be applied between  Intel Gigabit CT PCI-E and the built in NIC mentioned above?

or shall be 2 NIC (Intel Gigabit CT PCI-E)?.

 

I ordered the 10 PCs and i am confused in ordering the NIC shall it be 10 or 20?

my application requires  dual lan support teaming to setup one ip and use the load balancing,link aggregation...etc.

No ehternet adapter found

Hello everyone.

After cloning MAC adress on my Ethernet adapter Intel 82577LC, the error PXE-E05 occured (in OS windows 8.1 the ethernet adapter was with yellow exclamation mark and led on the adapter had blinked).

I found in the internet the solution, using IBAUTIL in MS-DOS mode to set default configuration .

After setting to default by using "IBAUTIL -NIC=1 -devcfg" my adapter is down.

No one LED blinks and in the device manager is not found (only wifi is found).

I tried once again to use IBAUTIL, but there write error "No supported network adapters found".

In BIOS I tried to set diffirent configuration, defaults settings, but still the network adapter is not found.

I tried also to remove battery for 10 minut, but nothing happened.

 

Could you mind help me with this problem.

Intel 82579LM Gigabit Ethernet - Small Packet Loss

$
0
0

Hi,

 

my issue seems to be related to Intel 82579LM Gigabit Ethernet - UDP Packet Loss, but in my case, small TCP packets get lost every couple of seconds.

 

In my case, a DELL Latitude E6520 notebook communicates with a WAGO I/O-System device via Modbus TCP at a "high" rate of small packets (TCP_NODELAY), i. e. around 1000 packets per second (9.58 % of size 66 byte on wire, 90.42 % of size 117 or 119 byte on wire according to Wireshark).

 

Every couple of seconds, it happens that a reply of the WAGO device doesn't appear on the notebook, causing a delay of magnitude 3 compared to the normal packet exchange, which severely impacts the hardware controlled by the WAGO device.

 

Notebook and WAGO device are connected by a D-Link DGS-1210-16 switch. Activating port mirroring on the notebook port and running Wireshark on an different PC connected to the mirror port reveals, that the reply of the WAGO device is actually sent to the notebook, but the notebook doesn't see it and therefore the TCP stack on the notebook requests a retransmission after a delay of about 1 second.

 

I currently work around this issue by mirroring the sent packets of the WAGO device to the notebook port on the switch.

 

The notebook is running with current BIOS and is connected to the mains. Recent Intel network drivers are installed, using default settings. Diagnostics doesn't reveal anything bad.

 

What can I further do, to get that issue fixed?

 

Thanks in advance. Bye.

Intel Gigabit CT Desktop Adapters all stop seeing other computers and server

$

I have 3 PC's, each of which is running Windows 7 x64, and each of which had no prior problems connecting to the internet or the network via their PCI-e Intel Gigabit CT Desktop Adapters.  Over the course of the last week, each PC started connecting to "Network 2", instead of the usual Network, and while they could connect to the internet, they would not see the other PCs on the network or the Windows Home Server.  I tried disabling the adapter, deleting the Network and Network 2 profiles, and then re-enabling the adapters.  While this allowed the adapters to connect to the Network Profile, none of the other PCs on the network or the WHS could be accessed, even though I still had full internet connectivity.

 

When I disconnected the ethernet cables from the Intel CT adapters, and connected them to the embedded adapters on each PC's motherboard, the network was instantly discovered, so I thinking the culprit must be the CT adapters.  However, it can't be possible that all three failed at the same time, or in the same manner.  There has to be something else going on...

 

I'm certainly no networking expert, so I would appreciate any help from the community.  I paid a decent premium for these adapters, and all are using the most recent drivers.  Suggestions?

 

Thanks,

intel pro/1000 mt server problems with CAT6 cables!

$

I have a new intel pro/1000 MT server adapter, adter so many problems to get it work (both on ubuntu 13.10 and windows), there seems to be a major issue in it's operation. when using cat6 patch cords (tried different 4 new patch cords all manufactured by Belden, and all tested to be OK by other adaprtos ) there is a huge packet loss, as much as the interface speed is in range of kbps when connecting to another GB interface, just by replacing the cable with any old cat5e, it would work fine! what could be the cause?!

 

let me repeat that I have checked those CAT6 cables, connecting other interfaces, and they work perfectly, the issue is only happening for this 82545gm intel pro/1000mt interface. as much as I know CAT6 is fully backward compatible! so I cant understand whats wrong in here! int

 

Update:

after checking the interface statistics I see many errors:

ethtool -S eth1

     rx_errors: 1670
     tx_errors: 0
     tx_dropped: 0
     multicast: 0
     collisions: 0
     rx_length_errors: 0
     rx_over_errors: 0
     rx_crc_errors: 9354

 

but I don't know the reason!

After installing this driver i started creating the vlans: 2 tagged vlans and 1 untagged vlan.

the untagged vlan is out primary vlan used to connect to our servers and internet.

This primary vlan didn't seem to work properly.. I could connect to the internet but not to all local servers.

When looking at the traffic flow on the server i was connecting to i saw traffic being send from the interface and toward the interface but it never reaches the browser. when reverting to version 18.8 it all started to work again.

 

further it is a pain to find a place where to file a bug report on this site..

I am testing RHEL 6.4 VMs (ixgbevf 2.6.0-k driver) on RHEL 6.5 Hypervisor (KVM with the ixgbe3.15.1-k driver) using SR-IOV .  I have a high-rate multicast application and it appears that every VM is receiving the packets for every multicast packet going into the PF, whether the VM associated with the VF registered for that multicast address or not.  Does anyone know if we have something misconfigured?    Is there anyway to configure the PF to only forward the multicast packets to VFs that registered for particular multicast addresses?

 

Thanks!

Freebsd 9.x - Wake on Lan not working

Hello,

 

I ran into the problem that wake on lan is not working with freebsd and intel nic.

 

Shutdown the system with poweroff, WOL is not working.

 

if I comment out

/sbin/ifconfig -l | /usr/bin/xargs -n 1 -J % /sbin/ifconfig % down

in /etc/rc.shutdown, wake on lan is working.

 

the catch - after the reboot, the interface doesn't react (no IP - not even static - can be assigned). I've to poweroff the machine again (with ifconfig down) for the interface to work again.

 

Port LEDs stay on - with and without ifconfig down.

 

Thanks,

Andreas

Speed setting

Hi,

I have installed PROWinx64.exe. in Windows 7 64 bits and trying to set speed of all the installed Intel NICs in the PC using PROSETCL. I use the Adapter_EnumerateSettings 3 command to get the settings of the NIC. I see *SpeedDuplex             - Auto Negotiation.

When i try to get the setting using: PROSetCL.exe Adapter_GetSetting 3 *SpeedDuplex

I get the following Error: Setting name not found: *SpeedDuplex

 

Does anyone know why it Settcan not find the setting name, although, is right.

Thanks.

Dell Latitude E6230, Windows 7, 82579LM, and NT Kernel and System

I have an otherwise functioning install of Windows 7 64bit edition. Sometimes, the process NT Kernel & system jumps to 20-30% from its usual 0. I can sometimes go a week without it happening. Sometimes, it's an hour. It goes away if I reboot. It also goes away permanently if I disable the 82579LM network card. So, that's the problem.

 

I've tried the Dell drivers, the last 2 or 3 versions of Intel drivers, and it still occurs. I've also tried virus and malware scans. Anybody have an idea how to fix it? It's not a huge deal, but I'd still like to fix it.
