| Are you machine and router really meant to be on different subnets? |

I am not sure what do you mean " to be on different subnets"
Ok. I have changed gw to 192.168.1.1

| So can you ping the g/w? Can you ping IP addresses on Internet? Can you resolve DNS? What do you get when you run ifconfig -a? |

OK. So you still have a residual from the previous error with broadcast address being on the wrong subnet 192.168.0.x.
Not sure if that would stop you reaching the G/W. Maybe. Can you please paste the output of |

Ok:
| Code: | localhost mirek # route
Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use Iface
192.168.1.0 * 255.255.255.0 U 0 0 0 eth0
loopback localhost 255.0.0.0 UG 0 0 0 lo
default 192.168.1.1 0.0.0.0 UG 0 0 0 eth0 |
and my working wireless:
| Code: | localhost mirek # route

| I notice that eth1 uses miroslaw as its default g/w. What is that? Is it also 192.168.1.1? |

| I am not sure how can I check it? I use dhcp for eth1 and static for eth0. I use also ifplugd, maybe it change any config? |

| You could look for it in /etc/hosts. You could ping it from the wireless set-up and see the IP that way. |

I am confused now.
My hostname:
| Code: | tux mirek # cat /etc/conf.d/hostname
# /etc/conf.d/hostname
# Set to the hostname of this machine
HOSTNAME="tux" |
and my /etc/hosts
| Code: |
127.0.0.1 localhost tux |
What I have to check now
BTW. If I unplug end plug my pcmcia card in again I miss the wireless connection. It will not help command /etc/init.d/net.eth1 restart, I have to reboot my laptop to get it back again. |

It is something wrong with my dhcppd-2.0.0 configuration. My /etc/dhcp is empty; I believe it should be dhcpd.conf file there?
I miss also /etc/conf.d/dhcp file.
As usual any suggetions would be much appreciated, Thanx |
