[CLOSED] After rebooting no connection with internet via router

[Goeroeboeroe]

After installing Lucid Lynx I still have some issues. Most of them I've solved by searching on Internet, but some things I couldn't find.

I have two computers connected via a router to the Internet. One of them, Windows XP <whisper mode> is working okay </whisper mode>.
After rebooting with Lucid Lynx there's no Internet. I have to log in the router with 192.168.1.1, click a few times on Quick Setup, Next, Next, Finish, and I've got Internet.
It looks like something is not written down somewhere, but I have no idea where I have to look. Could somebody please help me?

Do you still have knetworkmanager installed? It causes all kinds of problems.

Try this:

reboot
assuming no internet, open a terminal and type route
you should see

Kernel IP routing table
Destination   Gateway     Genmask     Flags Metric Ref  Use Iface
192.168.1.0   *        255.255.255.0  U   0   0    0 eth0
link-local   *        255.255.0.0   U   1000  0    0 eth0
default     myrouter.home  0.0.0.0     UG  100  0    0 eth0

or similar. I'd bet the last line is missing in your case. Likely this command (assumes eth0)
route add default gw 192.168.1.1 eth0

will bring up your internet connection (you may have to restart your eth0 also).

My suggestion is to remove knetworkmanager (search for a post on here on how to remove it completely) and then manually configure you interface. Takes about 2 minutes...

Thanks for the reply.
After booting I had again no internet. Route gives me this:

Kernel IP routing table
Destination   Gateway     Genmask     Flags Metric Ref  Use Iface
192.168.1.0   *        255.255.255.0  U   1   0    0 eth0
link-local   *        255.255.0.0   U   1000  0    0 eth0
default     192.168.1.1   0.0.0.0     UG  0   0    0 eth0

So that looks pretty much like it should look, in my opinion.
After manually connecting I looked again at route and the output is exactly the same.

I found how to remove knetworkmanager, but I couldn't find how to manually configure my interface.
Do you think I still should do this, even if the output of route looks good? I ask because I actually have almost no idea what I'm doing. Very long use of Windows probably put a virus inside my brains too...
And if I should manually configure my interface, could you give me a hint in what direction I should search for info how to do this? Searching on words like 'interface' gives very much pages.

Re: After rebooting no connection with internet via router

The favored solution to network problems seems to be to automatically remove knetworkmanager. Alright I'll say it, there's nothing fundamentally wrong with knetworkmanager. What usually happens is a conflict between network managers (i.e., knetworkmanager vs. wicd). They do not play well together. Pick one, keep it, blow away the other one(s). It's that simple.

From about 7.10 to 10.04, I played tag alternating between wicd and knetworkmanager with equal results. Each will work without the other, quite well. When I had 9.10 I blew off wicd and purged all things "wicd". Don't get me wrong, wicd is a fine product, but it is absolutely necessary to make choices. When I upgraded to 10.04, the process was so smooth, and the b43 driver just worked, and knetworkmanager just popped right up and worked without any necessity to use a wired connection to my router (as was needed in past upgrades), I just left it all alone. With the exception of certain PEBCAK errors, knetworkmanager has not had any problems or instability issues under 10.04.

So make your choice of network managers, blow off and purge any other(s), and all will be well.

Thanks for the reply, but I have only one networkmanager installed. wicd is not installed.
But in the mean time I've decides to quit Kubuntu completely because of the enormous amount of problems there are. So I'm not in need of an answer here anymore.

jglen490: The topic is closed I guess, but I'll comment anyway...

Although I believe you are correct about the issue of conflicting managers, most people don't initially install wicd, pointing to a larger fundamental problem with knetworkmanager. So I respectfully disagree with your assessment of knetworkmanager.

From what I've read on this board - almost everyone with a wireless connection has to remove it and install wicd.

I have to remove it from my wire connected machines because they have 2 nic's that are both connected and there is no easy way to correctly configure them using knetworkmanager. I use port aggregation, but even not doing that the interfaces simply aren't listed in the knetworkmanager configure dialog.

Of course, this is not a true cross-section if users. Obviously, those it works for aren't chiming in to say so. Also to be fair, since I started using Kubuntu with Jaunty and found knetworkmanager to be unusable then - I have just automatically removed it with each upgrade. I suppose I may give it a try again someday if they add in interface bonding - or not... 8)

I totally agree with your "Pick One" advise - I think many new users install everything with no idea that some packages don't play well together.
