Ethernet and Wlan must work Howto SOS

English Network/Internet
#1

I lost due to lightenings and flashes which came througe the telephone line within 5 month 5 mainboards, 4 grafic cards, 3 UPS’s and 2 CPU’s.(I m living in Thailand).
Therefore, I must disconnect fron the telephone line and go to wireless.

Since 2 month`s I try to get the wireless working and red through tons of documents including this thread.

I have 3 computers in dual boot Opensuse 11.1, 11,3 and 11.4 with 2x Win XP and win98se.

Windows I got to work, however Opensuse not.

With Opensuse I can connect with each of the other linux and windows systems througe ethernet only, but I can not connect to the internet.

The Linux data are as follows

The above was with configuring the devices at boot. I could connect to all hosts, but not to the internet, because it doesnot find the Wlanrouter which has the ip adress 192.168.10.1
I tried several weeks all variations i could think of, even with addroute, but without success. None of the 3 linux versions connected to the internet.

Now my last try was to remove all network cards, I deleted all configured devices and started newover using configurationmode if hotplugged for the wlan and if cable connected for the ethenet. Here are the results:

I tried again to add a route, but I got the message ‘192.168.10.0’ is not a valid network. Idont know what to do anymore.

I am very glad if someone cold give me some advise or help.

Thank you.

Use <CODE></CODE> tags (substituting the <> for ]) to post the output of commands in the future. It would be much appreciated.
You say you’re using the telephone line, so I take it there is a modem involved somewhere. Are your computers going to the router (you say they can interconnect so I’m assuming they are) or plugged directly into the modem?
If they’re directly connecting to the modem, take a look at wvdial.
If not, try and run

sudo dhcpcd eth0

replace the eth0 with wlan0 if you’re trying wireless.
I’m pretty sure all of your interfaces are up, but running

ifconfig eth0 up

can’t hurt.

My 3 computers are connected to a hub which was connected through cable to a Bell router-modem. In this way, they can communicate with each other directy.
I replaced the Bell by a wireless one, where each unit is connectd via an wireless USB-stick with the modem, and lan cables with the hub.

Here is the outcome of the commands you suggested:

bill10:/ Code: dhcpcd eth0
err, eth0: timed out
warn, eth0: using IPV4LL address 169.254.108.4

bill10:/ Code: dhcpcd wlan0

As i saw the routing table was changed I tried with yast to reconfigure the network cards, but this did not work. it came aways back to the original configuration and when I restarted the computer everything was like before.
Sure, because neither the wlan nor the network card were in the 192.168 network any more.

Thanks a lot for your help.

I finally got my systems to work. It was just to write manually the right routing tables
For Opensuse 11.4 it had to be different as for the 11.1 and 11.3

For 11.4 it is

bill10:/CODE netstat -nr
Kernel IP routing table
Destination Gateway Genmask Flags MSS Window irtt Iface
192.168.10.0 192.168.1.10 255.255.255.0 UG 0 0 0 eth0
192.168.10.0 0.0.0.0 255.255.255.0 U 0 0 0 wlan0
192.168.1.0 0.0.0.0 255.255.255.0 U 0 0 0 eth0
169.254.0.0 0.0.0.0 255.255.0.0 U 0 0 0 eth0
127.0.0.0 0.0.0.0 255.0.0.0 U 0 0 0 lo
0.0.0.0 192.168.10.1 0.0.0.0 UG 0 0 0 wlan0

For the 11.1 and 11.3 they are:

bill50:/ CODE netstat -nr
Kernel IP routing table
Destination Gateway Genmask Flags MSS Window irtt Iface
192.168.1.0 0.0.0.0 255.255.255.0 U 0 0 0 eth0

169.254.0.0 0.0.0.0 255.255.0.0 U 0 0 0 eth0
127.0.0.0 0.0.0.0 255.0.0.0 U 0 0 0 lo
0.0.0.0 192.168.10.1 0 0.0.0 UG 0 0 0 wlan0

I still dont know why they had to be different, but it works.
So my problem is soved.

Thank you again for your good hint with the command dhcpcd

If your router is at 192.168.10.1, then that first UG rule in the top table is
just plain wrong. Did you enter one with a typo? The tables for 11.4 should be
the same as 11.3.
