Hopefully this might have helped others aswell with the same problem.
Im not to bright with Linux yet so just trying to learn so sorry if I dont understand what u mean, please make it as simple as possible for me to understand.

NOTE: Every now and then an Internet connection appears, I can get onto the net when this happens but then it may just drop out 5 seconds later or so, then no internet connection again? Sometimes it gets really bad and my PC loses connection with card and I have to reboot, sometimes it works and sometimes it doesnt and at that point im screwed and try to reinstall Debian?
Oh by the way I am setting up through DHCP, NOT Static Ip, I did try Static IP and it worked but I think it was a fluke cos it dropped out again? Any ideas guys and girls? It must be a hardware problem yeh? But I tried another card and it was the same problem? Thanks for your help

hmmm...interesting...


Have you tried completely bypassing your router? If you have a cable modem, just plug it straight into your Linux box, allow for DHCP, and see if you can access the Internet.

I believe I had more or less the same problem you have, for me it really worked just changing my connection to static IP instead of DHCP like this:

Edit the following file: /etc/network/interfaces and change your eth0 configuration to static, here's an example of mine:

auto lo
iface lo inet loopback

iface eth0 inet static
address 192.168.1.11
netmask 255.255.255.0
gateway 192.168.1.1



auto eth0

You can find your adress and mask typing "ifconfig" in your terminal.
For your gateway you can type "netstat -nr".

It's fairly simple, all you need to do is open a Terminal and run the following commands:

su
<enter your root password>
gedit /etc/network/interfaces

Or if you're using a different window manager, substitute 'gedit' with 'kate', etc.

Hope this helps.

Also, if you can surf by IP address without running into any issues, you might wanna check to see if your DNS servers are resolving properly. Because if that's the case, then you are getting a valid connection to the Web. And that would explain why the problem rolls over to all the various browsers.

Definitely. You should check out your /etc/resolv.conf file and see which nameservers you're using. Perhaps your ISP's nameservers are down. If that's the case, you should easily be able to use some other nearby nameservers, seeing that you don't have any problem connecting to the internet.

Bizzarre. Linux should atomaticly jack itself into the internet if you have an Ethernet cable plugged in.

Not to strange, really. Tezux is connecting to the internet... just having a little issue with DNS resolving. And the /etc/resolv.conf file that John suggested should shed some light on what's happening for us.
