Hi Folks.

Recenlty I purchased Acer Aspire 3002 notebook with AMD Sempron 2800+ Processor . I have installed FC3 & XP Professional (Dual Boot) on that, now everything works fine under Win XP. But when I switch to FC3, I can not connect to my network(LAN).

Following is my eth0 setting.
IP: 192.168.1.150
SM: 255.255.255.0
GW: 192.168.1.1.

I can ping successfully to eth0, that is 192.168.1.150, but when I try to ping my gateway ip address, I get "Destination Host Unreachable" from 192.168.1.150. I am not able to understand why this is happening, initially I suspected the cable, but the same cable working fine on XP. I also tried to connect one other PC directly with my notebook using "ethernet cross cable" back-2-back, but still no success.I checked everything whatever I can, but not able to get any clue for not working.

Please help !.

It is possible, yet difficult and moronic, to block out computers running Linux or Windows or any other OS specifically. This is due to the fact that every OS has slight differences in how the TCP/IP packets look.

I doubt that this is the case, but it could be.

Have you tried pinging another computer on the network than the gateway?
if you are able to do so, and get a result it MIGHT be that Linux is blocked by your gateway.

IF you find that you can ping other computers on the network, try talking to who ever is providing the gateway and ask if they are intentionally blocking out Linux computers.

Have you tried with another computer? Distro?

Hi Clearer..

I already checked this with other PC, I can not ping any other PC in my network(LAN) with my notebook !. Always it shows that "Destination Host Unreachable"...

Guys..

Here one more thing I would like to tell. My notebook is detecting the cable and ethernet physical speed and duplex mode. As when I give the command "mii-tool -w", it shows the current negotiated speed/duplex mode.

# mii-tool -w
15:20:30 eth0: negotiated 100baseTx-FD, link ok

Now when I remove the ethernet cable from either end and it detects that.

15:20:49 eth0: no link

So cable and physical port has no problem at all. Now I don't know much about FC3 TCP/IP stack. How it works..

Hi,

I had the same problem, which I resolved by adding acpi=noirq as a kernel
parameter in /etc/grub.conf.

I figured out the solution after finding out that none of the packet countes were
getting updated or the interrupt routines getting called of the card.

Hope that helps.

Thanks and Regards,
KK.
