Wired Internet problem thru Belkin Router # F5D5231 in Dell Inspiron 9300

Hi,
First, which light do you have turned on or blinking?
Second, can you please open a terminal (Applications->Accessories->Terminal), execute the following command:
 lspci
and paste the output here.
Do you have a username and a password to connect to comcast?
It seems like your wired net card not be installed.

Thanks for your reply. Actually, this is my laptop and I have other Desktop running on XP connected to this Belkin Router (and internet is working fine in that-so Belkin router ports are forwarded correctly). The laptop has integrated network card. Please find the results of lspci command below:-

Thanks again for your support. You guys are good!

Seems you have two network cards eth0 and eth1 the eth1 seems have dropped packet

I think because your eth1 card have same ip address of your router 192.168.2.1

So please set your networkcard as DHCP double click on the top right network monitors icon and do the setting from there.

Hope this helps

I don't really get you. I changed the Method to Automatic (DHCP) under IPv4 tab in connection properties. Is that correct? Please let me know how to set network card as DHCP.
Thanks again
Ann

Yes please set also eth0 in thee same way then please try to reboot your pc...

Hope this helps

Thanks. Still it's not working. I am pasting here the config in my /etc/network/interface

***************************************************

Please let me know what is wrong here. If I uncomment
#auto eth0
#iface eth0 inet dhcp
Then, network icon disappears from the panel. What am I doing wrong? Why simple wired networking such a nightmare in Ubuntu?

Thanks for your support.

Also when I tried to restart the networking, the following messages are displayed:

*************************************************

Seems network 192.168.2.1

must be changed to:

network 192.168.2.0

and please add the gateway if you are sure your router has the 192.168.2.1 ip

gateway 192.168.2.1

----------------------------------------------------

By the way here to get dhcp my /etc/network/interfaces are set like below:

auto lo
iface lo inet loopback

auto eth0
iface eth0 inet dhcp

So your must be something like this to try them working with DHCP:

auto lo
iface lo inet loopback

auto eth0
iface eth0 inet dhcp

auto eth1
iface eth1 inet dhcp

Hope this helps

So please try to set your network with static ip please don't use network manager...

Open a terminal from Application → Accessories → Terminal and type:

sudo gedit /etc/network/interfaces

(if the system ask you a password give your user password, you will not see nothing when you type it, then press enter)

and please copy and paste this contents:

auto lo
iface lo inet loopback

iface eth0 inet static
address 192.168.2.10
netmask 255.255.255.0
gateway 192.168.1.2
nameserver 208.67.222.222

iface eth1 inet static
address 192.168.1.11
netmask 255.255.255.0
gateway 192.168.1.2
nameserver 208.67.222.222

Save and exit then restart your network type:

sudo /etc/init.d/networking restart

and try to connect to a site using Firefox

Hope this helps

Sorry, the latest is what i want send to you...

Thanks again. It didn't work yet. Before rebooting, a quick question:
1. if my router ip range is configured form 192.168.2.101 to 192.168. 2.110, should i change the address in your config?
2. Is the nameserver valid to my case?
Thanks for all your support. Sorry for being a pain.

Unfortunately it didn't work. Now the networking window diasppeared from the panel. What I doing wrong? Why is it hard to configure wired network in Ubuntu 8.1? Should I install 8.04>? Thanks for your help

Are you sure of your router settings...?

Can you ping your router now...?

is your eth0 or eth1 set UP if you do an ifconfig -a command...?

Can you try to use eth0 instead of eth1 to connect your router....?

Thank you

Thank you very much. I made a small change and it worked! I changed the code in eth0 from static to dhcp
auto eth0
iface eth0 inet dhcp

It worked like a charm. Thanks for all your patience and support

Thanks marcobra, that solved my question.
