Ethernet port active but not working after F7 install

MichaelS-R · #1 7th September 2007, 08:16 PM

I have just installed a completely new F7. I have a Tyan Thunder K8WE(S2895) motherboard with 2 built in ethernet ports. Only 1 port is detected and I cannot ping anything, other than my own ip address. Error message reads: Network is unreachable.

I think that I have a driver problem but am not quite sure where to start...

By the way, I had it all working nicely under FC4 for some time.

Many thanks,

Michael

Check your route settings, try command:

/sbin/route -n

and

/sbin/ifconfig

Put the output here. If worked fine in FC4, I don't think is a driver problem, may be a configuration problem. Are you using dhcp?.

Some on-board NIC's are having troubles.
What bran, model?
Which is etho, eth1?
Describe your network components(how is it all hooked up?) - dsl, dsl-router-firewall, gateway machine.
Is DHCP on? Y or N?

Problem solved thanks - silly really, jut wrong subnet mask!

While I am at it though, not entirely sure that I understand this... What is virbr0 anyway?

route -n output:

ip address is supposed to be 192.168.0.153 with gateway of 192.168.0.1 and same for DNS.

virbr0 is a kind of virtual interface used by xen. I never used it
