This is confuzzling.

In vista I type in my routers ip 192.168.2.1 and it shows the router settings

ubuntu I do the same and it says cannot connect to server. Internet works fine though.

Any help is much appreciated

Can you ping it? What is the ip it has given to you by DHCP?

growse · 10 Feb 2008 at 21:18

To get the ip address, bring up a console and type 'sudo ifconfig'. Should get something like:

Code:

tickle growse # ifconfig
eth2      Link encap:Ethernet  HWaddr 00:04:23:64:7D:C3
          inet addr:192.168.0.2  Bcast:192.168.0.255  Mask:255.255.255.0

          inet addr:127.0.0.1  Mask:255.0.0.0

          RX bytes:64581951 (61.5 Mb)  TX bytes:64581951 (61.5 Mb)

In this case, my ip is 192.168.0.2.

The others computers use dhcp range 3 to 100 but I use static 2 router is 1

You seem to have an ip address of 192.168.2.2 on both nics, but it seems to be using eth1. Can you type 'route' - output should look like:

Code:

tickle growse # route

You have two NICs with the same IP...

EDIT: Beaten to it!

Think we've missed some things:

Can you do the following:

Code:

ping 192.168.2.1

then

Code:

traceroute overclockers.co.uk

and post the results?

Can you access the router from any of the DHCP clients?

Ross1234 · 11 Feb 2008 at 17:11

Ross1234 · 12 Feb 2008 at 14:06

anyone?

.walls · 12 Feb 2008 at 18:02

As said above - both NICs having the same ip address should be addressed.

How about do the easy thing and either:

a) Unless you are using both NICs, disable one.
b) Manually set the ip address of one NIC to something else
c) Set both NICs to DHCP

The latter two are less preferable, as it's generally a good idea to not have two NICs from the same box on the same subnet.

Ross1234 · 12 Feb 2008 at 18:22

Sorry, what is an Nic?

tntcoder · 12 Feb 2008 at 18:25

Nic is your network interface card, basically as said you have two of them both using the same IP address, which is probably causing a conflict.

you can use ifconfig to change the ip (temporarily), i.e ifconfig eth0 192.168.1.x

I went in the BIOS and disabled onboard LAN.

It worked and I can now access the router settings on 192.168.2.1

Thank you all for helping me
