Ubuntu 9.10 no wired or wireless connection

Asked by tecexec on 2009-11-06

I loaded 9.10 on a Compaq Armada M300. I can not get on my home network. There are no propriety drivers and ifconfig sees the hardware. However, they will NOT connect. If I try the NIC wired connection, it tries but end up saying "wired connection: disconnected, you now offline. The really peculiar thing is the router see both the NIC and wireless card, which it identifies the MAC addresses and even assigns IP address. If I try /etc/network/interfaces, it says bash: /etc/network/interfaces: Permission denied.

Here is printout of ifconfig:

you cannot run dhclient as a user. You must run it like this:

sudo dhclient

you should also try connecting an Ethernet cable between the system and router and run:

sudo dhcllient eth0

If this fails, you may have to try and set the network with a static IP suitable for your network and see if communications will flow.

Can you help with this problem?
