 Posted: Tue Jan 13, 2004 12:32 am Post subject: Wireless NIC cannot connect to another machine |
 |
|
i have two wireless NICs on the same channel and yet they cannont ping each other. i get | Quote: | | "From 192.168.1.2 icmp_seq=3 Destination Host Unreachable" |
192.168.1.2 is my ip on the machine that is pinging
any ideas?
They have the same subnet mask and they have the same ip range both on channel 3 and both adhoc connections
Here is my setup:
My Gentoo box 2.6.0 : -
with a wireless network card (yenta and orinoco) - which connects to pc 2 a windows 2000 box (eth2)
with a broadcom bcm4400 connected to cable broadband modem (eth0)
with a rtl8139 connected to an XBOX console. (eth1)
here is my ifconfig | Code: |
eth0 Link encap:Ethernet HWaddr 00:E0:18:9D:85:5C

and here is my iwconfig | Code: |

my /etc/conf.d/net | Code: |
iface_eth0="dhcp"
iface_eth1="192.168.1.1 broadcast 192.168.1.255 netmask 255.255.0.0"
iface_eth2="192.168.1.2 broadcast 192.168.1.255 netmask 255.255.0.0"
|
I tried making links to /etc/init.d/net.eth0 called /etc/init.d/eth1 and eth2 but it didnt work so i copied and pasted the files and renamed them in the same dir and it worked for them. otherwise they were not coming up in the startup sequence. i had to bring them up manually iwth ifconfig eth0 dhcp and ifoncifg 192.x.x.x/24 etc. |
