intel pro/1000 ct gigabit ethernet never can connect at 1000 only 100

[sdowney717]

This is a builtin device to motherboard, Intel server S875WP1-e

I tried different cables, and moved switch next to PC. I also tried Ubuntu.
The cables do work at gigabit speeds.

So does anyone know why?
It is enabled in the bios. And latest bios p18 is installed.

I tried installing the intel win32 drivers for ethernet, and it errors saying there are no intel adaptors are present, yet they are. This board has 2 builtin Intel ethernet controllers..

What is the make/model of the switch? Is the switch gigabit capable?

 

[sdowney717]

It is a gigabit switch, trendnet TEG-S50G

It wont connect at 1000 straight on to another gigabit nic card in another pc either.

What colour is the 100/1000Mbs LED showing on the switch? The manual does state to use either CAT-5E or CAT-6 cables, and that not all CAT-5 cables are gigabit capable.

Hi sdowney717,Which revision # is the nic ? download the manual from here TRENDnet | Downloads | Switches | TEG-S50G(v3.0R) for either rev 1 or rev3 see if this helps

 

[sdowney717]

"revision # is the nic"

how to tell, I went into properties and set to 1000 full duplex, still at 100.

on the port, both lights are green on motherboard.

3.9 Network Interface Controller (NIC) Subsystem
The Intel Server Board S875WP1-E supports two Network Interface Controllers (NICs), one that
runs at 10/100Mb and is based on the Intel 82562ET NIC and the other that runs at one gigabit
and is based on the Intel 82547EI NIC. When looking at the rear of the chassis, the gigabit NIC
is at the left (closest to the video port) and the 10/100Mb NIC is at the right. The Intel Server
Board S875WP1-E supports independent disabling of the two NIC controllers using the BIOS
Setup menu.
The NIC subsystem consists of the following:
36 Intel 82801ER ICH5-R device with an integrated LAN Media Access Controller (MAC)
37 Intel 82547EI Platform LAN Connect (PLC) device for 10/100/1000 Mbits/sec Ethernet
LAN connectivity
• RJ-45 LAN connector with integrated status LEDs
The 82562ET is controlled by the ICH5 and supports the following features:
38 Integrated IEEE 802.3 10Base-T and 100Base-TX compatible PHY
39 IEEE 802.3u auto-negotiation support
40 Full duplex support at both 10 Mbps and 100 Mbps operation
41 Low power +3.3 V device with reduced power in unplugged mode and automatic
detection of unplugged mode
• 3-port LED support
The 82547EI is controlled by the CSA interface off of the MCH and supports the following
features:
42 Basic 10/100/1000 Ethernet LAN connectivity
43 Integrated Gigabit Ethernet Media Access Control (MAC) and physical layer (PHY)
44 IEEE 802.3 10BASE-T/100BASE-TX/1000BASE-T compliant physical layer interface
45 IEEE 802.3ab Auto-Negotiation support
46 Low power (less than 350mW in active transmit mode)
47 Reduced power in “unplugged mode” (less than 50mW)
48 Automatic detection of “unplugged mode”
49 Communication Streaming Architecture (CSA) port provides higher throughput and lower
latencies resulting in up to 30% higher bus throughput (up to wire speed)
50 Full device driver compatibility
51 Programmable transit threshold
52 Configuration EEPROM that contains the MAC address
• Teaming and Fail over support

trendnet switch is unmanaged and works on gigabit speeds to 2 other PC. Cable I tested works at gigabit but when plugged into Intel server board, only gets 100.

 

[sdowney717]

I dont see any revision numbers.
under properties, driver version is 8.4.1.1, file name is E1G60132.sys

I set to link speed 1000 full duplex
gigabit master slave mode auto
flow control tx and rc
Adaptive interface spacing enable
tried turning off other items, anyway still at 100

So the speed switch is showing green? According to the manual, that indicates a 100Mbs connection. For 1000Mbs, this indicator needs to be showing orange.

 

[sdowney717]

This is a ver2 switch not version 3
This switch reports speeds with green lights.
2 lines one 1000, under that 100
Link line 1000 all green
link line 100 all green

trendnet shows green on all connection speeds regardless.

IS it possible that this intel pro/1000 ct must have cat6 cable to work at gigabit speeds?
Only other thing is it is broken.

What OS are you running on this board?

I wasn't referring to the indicators on the switch, but those on the NIC socket on the motherboard.

 

[sdowney717]

it is windows 7
also seriously, green leds only show up for the 1000 connections on the switch. Maybe version 2 of this switch differed.

Ok, on the motherboard, the 1000 port is all green both sides = 100.

The following link is for the latest Vista drivers for the 82547EI 10/100/1000 Gigabit Ethernet LAN (you may need to install this in http://www.sevenforums.com/tutorials/316-compatibility-mode.html).

http://downloadcenter.intel.com/Det...ersion= &DownloadType=Drivers

 

[sdowney717]

I tried that with compatability mode and get the error

No Intel adapters are present in this computer.

why does it say that? Does it consider the intel motherboard with intel networking non intel?

There is win7 install version and I get the same error.

 

[Dwarf]

Strange. It could well be that for some reason or other an alternative NIC was installed on your particular board.

With reference to http://www.sevenforums.com/tutorials/73420-hardware-identification.html, can you give me what information shows for all devices in the Network adapters section. It should look something like PCI\VEN_10DE&DEV_0611&SUBSYS_00000000&REV_A2 (copied from Tutorial).

 

[sdowney717]

I took a screen shot showing it is an intel nic.

 

[sdowney717]

sure, here are the details

PCI\VEN_8086&DEV_1019&SUBSYS_34288086&REV_00
PCI\VEN_8086&DEV_1019&SUBSYS_34288086
PCI\VEN_8086&DEV_1019&CC_020000
PCI\VEN_8086&DEV_1019&CC_0200

 

[sdowney717]

This is an 82547GI embedded controller
Which reached end of life in 2012
so is there a driver?
ARK | Intel® 82547GI Gigabit Ethernet Controller

which is supposedly this one, but when run says no adapters present

pic showing this.

 

[Dwarf]

Thanks. That confirms that the board does indeed have the 82547EI NIC installed and, following the links from the database referred to in the Tutorial, I arrive at the same downloads as before.

It could be that the controller is faulty, and is only working at 100Mbs. You said that you also tried Ubuntu and got the same result, so I wonder if my hypothesis is correct.

See if you can get hold of a PCI Gigabit network card to check this out. Alternatively, you might just have to accept that the board only works at the 100Mbs speed.
