Wired ethernet connectivity

[bogdanbiv]

Hello,

I've been trying the /almost/newly/ released version of Kubuntu Karmic on my HP 6730s laptop and I've been experiencing a weird problem with network connectivity. Wireless network works fine, I can browse the net all day long, but wired ethernet is not working. As soon as I put a cable into the RJ45 on my laptop, I cannot connect to any sites, even though both wireless and wired ethernet have valid IP addresses (via DHCP).

Here is a ping when wired ethernet is unplugged:

$ ping -c 1 google.com
PING google.com (74.125.45.100) 56(84) bytes of data.
64 bytes from yx-in-f100.1e100.net (74.125.45.100): icmp_seq=1 ttl=46 time=139 ms

And here is a ping when I have plugged in wired ethernet:

What can I do? Dolphin -> Help -> About KDE reports that I have KDE 4.3.2. I believe to have the latest updates. I'll test as soon as I can the Kubuntu Live CD to see how ethernet works.

Re: Wired ethernet connectivity

It turns out that I didn't have the latest packages installed. Even if I didn't see the update notification manager, when I ran sudo aptitude safe-upgrade there were 327 packages to be upgraded.
I'll see how this goes after restarting the system.
