debian netinst: upgraded kernel; cannot access internet.


Recently, I did a fresh netinst of Debian 3.1. I upgraded the kernel using apt-get (because x-window-system only works with 2.6.8). After I boot 2.6.8 though, it seems to have trouble accessing the internet. For one thing, trying apt-get install x-window-system gives me lots of "Temporary failure resolving: '<host name>'" errors. Also, pinging 192.168.0.1 gives me "connect: Network is unreachable." I checked my /etc/resolv.conf and everything seemed to be in order. Any ideas?

It is worth noting that my internet worked on version 2.4.27 of the kernel, which was originally included with the installation. I have that kernel available in case anything else needs to be installed.

ifconfig
should show you your interfaces. Are they up?
/etc/init.d/networking start
may be needed.

Tell us about your hardware, particularly the interfaces to the internet. Do you have an ethernet card (NIC, Network Interface Controller) or a connection on the motherboard? Do you intend to use dial-up?

To show some of your hardware devices:
lspci
On my machine, among many other lines, I get these two:
Quote:
0000:00:06.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL-8169 Gigabit Ethernet (rev 10)
0000:00:0b.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL-8169 Gigabit Ethernet (rev 10)


To show installed modules:
lsmod

Among others, I get
Quote:
r8169 18436 0

Is there anything in the output about interface devices?

You can also skim through
dmesg
to see what may have been detected at boot time. You can also see stuff in /var/log/messages

I have an external RCA broadband cable modem, which I use to connect to the internet. Based on the output below, I may have an ethernet card, but I am not certain. I do not use dial-up. In addition, I use a D-Link DI-604 (residential gateway) router.

Of particular interest, I noticed

Code:
#lspci

seemed to be related to the information output by lspci.

I do not believe dmesg revealed anything of interest, but in /var/log/messages, I noticed

Code:
#vim /var/log/messages
...
Mar 17 14:25:48 localhost kernel: eth0: VIA VT86C100A Rhine at 0xcc00, 00:50:ba:af:9c:a5, IRQ17
Mar 17 14:25:48 localhost kernel: eth0: MII PHY found at address 8 status 0x782d 05e1 Link 45e1
...
I will attempt to install the newest version of the kernel (2.6.15, I believe, as opposed to 2.6.8) to see if that has any effect.

I have unsuccessfully attempted to install a newer version of the kernel. Unless anyone thinks it would be a good idea otherwise, I have given up...I do not believe there are significant enough differnces between the 2.6.x versions to solve my problems.
