Cannot get past modem
 
Hey Guys

I am sure I just missed something simple, but I do not do much wireless.

Wireless nic -> wireless router -> cable modem -> internet

Ok, I get an ip from the router, I can ping the router and the modem. Connection to the setup page of router and modem are accessible, but nothing beyond the modem. At first I thought I had DNS misconfigured but it does not like IPs either.

[root@localhost ~]# netstat -nr
Kernel IP routing table
Destination Gateway Genmask Flags MSS Window irtt Iface
172.16.227.0 0.0.0.0 255.255.255.0 U 0 0 0 vmnet1
192.168.0.0 0.0.0.0 255.255.255.0 U 0 0 0 ra0
172.16.238.0 0.0.0.0 255.255.255.0 U 0 0 0 vmnet8
0.0.0.0 192.168.0.1 0.0.0.0 UG 0 0 0 ra0
Router is at 192.168.0.1, modem 192.168.100.1.

The only thing I can see is that the destination is 192.168.0.0 and I THINK it should be 192.168.100.1, but have no idea where to change it.

Thanks

What is the output from
Code:

ping 74.125.77.103
ping www.google.com

It just times out, that was how I knew it was not just a DNS issue.

If your MODEM's IP address is 192.168.x.x then something could be amiss upstream.
Do you have any wired computers working?
New or existing internet setup?

lazlow 09-22-2009 01:59 PM

The wired connection (next door, windows) seems to be working fine.

Is the modem connected ?

lazlow 09-22-2009 03:13 PM

Yes, I gain access to the control page of the modem(but no further) and the other computers can access the web through the modem/router.

repo 09-22-2009 03:15 PM

Can't you copy the settings from the other computers ?
IP,GW, netmask ....

lazlow 09-22-2009 03:22 PM

The only number that seems to be different is the destination ip. If you can tell where to change that I will be glad to try.

repo 09-22-2009 03:36 PM

How do you setup the wireless connection?
Via GUI or CLI ?
If you mean by destination IP default gw
Code:

ifconfig add default gw xxx.xxx.xxx.xxx
