Limited access to the internet via wireless or wired after an apt-get update on deb 6
Hello people,
Having a few issues and I'm a bit stuck as to what has gone wrong. Have updated the distro using apt-get update and apt-get upgrade.
Using firefox and chromium I cannot connect to google even when pinged but can connect to facebook. Can ping facebook but the pages that come up arent like the normal facebook page. Can ping facebook fine.
It's a shot in the dark, but since you can connect to some sites but not others, try clearing your browsers' caches. It takes seconds, can't hurt, and might help.
What are the contents of /etc/network/interfaces and what DNS settings are you using?
Some things I can notice
- you have an eth1 interface, probably made out of nowhere, unless you have a wireless card or another nic
- that eth1 interface is not configured at all in /etc/network/interfaces
so are you sure you are using the proper interface to connect to the outside world?
Not sure why it changed on its own; probably the upgrade replaced the interfaces file (or any other) for some reason. Anyway, once you know which interface is linked to each card, you can check this link on Debian network configuration in order to set up your connection.
Also, being a laptop, which will probably need to connect to different APs, I would install some GUI network management tool, like network-manager, wicd, or any other of your preference, to ease the connection process each time you switch to a different AP.

Ah have been messing about and noted that plugged in to the router it does seem to be able to apt-get upgrate. But still cant access the internet via firefox or chrome. Chrome get the message Error 102 connection refused and unknown error.
Eth1 is the wireless card. The config of the wireless card is on here as I had issues.

Sorry taken a while to get back to this.
Why would there suddenly be a problem when there wasn't before? Having installed debian for the same disc on another laptop, a friends old Dell D600. I have compared that laptop to mine,. On her laptop:
When I do cat etc networks, this is the output

# This file describes the network interfaces available on your system
# and how to activate them. For more information, see interfaces(5).
# The loopback network interface
auto lo
iface lo inet loopback
I don't have a solution, but a long-shot suggestion; it's more a "rule out" idea than anything else. At the least, if it works as I expect, you can rule one more possibility out of the list of suspects.
Boot to a live CD of something and test your network connections, both wired and wireless. If they work, it's almost certainly something to do with your software load/configuration. If they don't, there may be some weirdo hardware thing going on.
