Cannot connect to internet

[venutip]

Hi,

I have installed Mandriva 2006 Free on my Windows XP machine (dual-booting) and everything is fine except the internet. I connect through a D-Link router to a cable connection. It is not wireless. Under Windows, everything is fine, but when I get into Linux, I can't access anything. The connection uses DHCP.

Here are the results of some commands that I ran:

ifconfig

ping
[paul@localhost Desktop]# ping www.google.com
ping: unknown host www.google.com

I also checked the contents of resolv.conf. The entire contents are as follows:

nameserver 192.168.0.1

This makes sense to me; the router's IP address is 192.168.0.1.

I've tried a lot to get this thing to work, but it ain't happenin. I had the same issue on Debian, too.

Anything you can tell me will be greatly appreciated. If you need more info I will be happy to supply it.

Thanks.

try changing it to a static ip, and make sure that you give them Host Names, when it prompts you. i had a similar problem, i also got it to work with DHCP, make sure you dont give a DHCP host name, have it obtain it automatically.
sorry its only a little bit of help, but i am also new. i dont know a whole lot about linux yet =D still learning

[maebjkcaz]

OH YEAH! aaannndd.... dont forget to reboot after you set up the connection, cant tell you how many times i thought something was wrong when all i had to do was reboot. good luck.

I have tried giving it a static IP. I used the Configure Network dialog in Gnome 2.10. It's currently using DHCLIENT. I gave it the following info:

• IP--192.168.0.115
• Network mask--255.255.255.0
• Gateway--192.168.0.1

Didn't give it a host name. Also, I'm sure that the IP I gave it is not already in use. And I have restarted many, many times.

Shouldn't the gateway be 192.168.1.1 ? (dunno, it migth depend on your router)
If you put that address in a browser-window do you get the route-config page?

Also shouldn't the resolv.conf contain the actual nameserver-addresses for your internet-provider? On my system i get 2 addresses (not the gateway).

[darkrose0510]

Can you ping the router? Then like muha says try entering the router address in a browser window.

If you can access your router but not the web, try restarting the network by rebooting the router and then your PC.

Also see if you can ping a domain by IP address rather than name - try 64.233.167.99 (google.com) - just to be sure your DNS connection is OK.

The router is definitely at 192.168.0.1. I've configured it many times using the web-based interface. I have not tried to access it from within Linux -- I should give that a shot and see what happens. But that is its address, for sure.

I will try to edit resolv.conf. But how do I find out what the nameserver address is for my internet provider? I have Comcast (not that it matters).

give your ISP a call, or check their site ..

Did you give the computer a static IP with the dlink comtrol panel? If not then you need a static IP outside the DHCP range, my guess is that your static IP should be changed to 192.168.0.5 but it has been a while since I have used dlink routers. And your gateway should be the IP of the router, in this case 192.168.0.1. Oh and one more thing, what happens when you try to ping your router or other computers on the network?
