Wits END! Cant configure Intel 82577LM Gigabit on dell e6410


All - Ive been trying everything possible, and cant get this Intel card to connect. Here are the details
Centos 5.5 Kernel 2.6.18-194.el5
Intel 82577LM Gigabit on dell laptop e6410

Broadband router with gateway 10.54.7.1
My network is 10.54.7.*

linux sees the exact card in the configuration utility.
If I choose dhcp, and try to bring up teh device, I get "no network, cable unplugged?" error

If I configure static ip for eth0 like
10.54.7.2
255.255.0.0
gw 10.54.7.1

The interface will come up (seen in ifconfig) but cant ping the gateway.

At one point it did work... I just cant get it back - Ive reinstalled like 4 times... in hopes Id catch something different, no luck. My network serices about 10 pcs many of them centos linux - no problem using static or dhcp with my router- I just got this new laptop and cant get ths card to work.

Man -Ive tried all the configuration possible - can someone PLEASE help me! I would be forever greatfull!

Thanks!
Bob

Also should mention if I ping the router I get "destination host unreachable"

If I do tcpdump -l
if says "listening on eth0" but just sits there.
Probably because there is no traffic

if I do route, it gives

destination gateway
10.54.0.0 *
169.354.0.0 *
default router

all for iface eth0

Router is defined in /etc/hosts

I dont know where the 169 address is coming from....? Not from me, thats for sure.

Its a little difficult getting output because the laptop is off the network.

Hope this helps

The 169.254 address (assuming you meant 254 instead of 354) is automatic private addressing and is usually automatically assigned if your host can not talk to a dhcp server when setup to get a dhcp address. You should disable dhcp for the time being.

Have you tried using a different cable? When you assign yourself a 10.54.0.0 address, are you able to ping the address you applied to the interface? Have you tried disabling dhcp when using a static address? That "destination host unreachable" also suggests that there is a problem with your routing table.

I dont see any dhcpd in chkconfig or services, I dont think dhcp is running.


Have you tried using a different cable?

Ive tested the cable and even switched it out - not the cable.
If I ping.. I can see the yellow light flash on each ping

If I dont ping the yellow light dosnt flash, when I ping it flashes with each ping


When you assign yourself a 10.54.0.0 address,
are you able to ping the address you applied to the interface?
Yes I can ping my address which is 10.54.7.2
The dhcp on teh router dhcp pool starts at 27- and up to 200

Have you tried disabling dhcp when using a static address?
I dont thnk dhcp is enabled

That "destination host unreachable" also suggests that there is a problem
with your routing table.

Ive captured some output via usb drive

here is the output of route
Kernel IP routing table

Destination Gateway Genmask Flags Metric Ref Use Iface
10.54.0.0 * 255.255.0.0 U 0 0 0 eth0
169.254.0.0 * 255.255.0.0 U 0 0 0 eth0
default router 0.0.0.0 UG 0 0 0 eth0

here is the output of intels netdriverinfo.sh

eth0 : 00:19.0

Make/Model = Dell Unknown device 040a
Ethernet controller = Intel Corporation 82577LM Gigabit Network Connection
VenIDevID = 00:19.0 0

Make/Model = Dell Unknown device 0010


Ethernet controller = Broadcom Corporation Unknown device 4727
VenIDevID = 02:00.0 0

here is ifcfg-eth0

Also an Eth0 issue on a Dell E6510?

Did this get resolved? I think I may have the exact same problem with a Dell E6510. It was working yesterday, but refuses to work today.
