Wired Connection Not Working - HELP!

[Guest]

I have a Belkin router with wireless connections using WPA2 AES. But I'm trying to set up a desktop PC with KUBUNTU 11.04 with a wired connection to the router. I can't get the system to recognize the router connection. If I manually add in IP and DNS information it says it's connected but I can't connect or even ping to anything on my network. How do I set up my wired connection?!? I was really looking forward to trying Linux on my home network, but if it won't even connect it is of little use to me. HELP!!

Running KUBUNTU 11.04 stand alone.
Running KDE - Platform Version 4.6.2
No other OS's running
PC is HP Pavilion a1130n running AMD64 32bit
3 GB Ram installed
2 HDs installed (1) 250GB with KUBUNTU installed & (2) 500GB for personal storage
2 optical drives (1) CDWriter & (2) DVDWriter

Re: Wired Connection Not Working - HELP!

Hi there,

Does your desktop see the router via wireless connection and is it able to connect and browse the internet?

Is there another desktop/laptop running the same or another OS which you can plug to the router's ethernet connection?

Have you also tried using another ethernet cable or rebooting the router?

I know these are basic questions but, IMHO, they're a very good starting point.

Thanks very much.

From,
Jude

Re: Wired Connection Not Working - HELP!

its possible that your wired network card requires a propriatary driver (very rare for them btw). when you have established your wireless network connection (if you can) try using jockey (the additional driver tool) to see if you have a "restricted" driver for that card. you might have to update your package cache before you see drivers. (do that thru your package manager, look for reload/update button)

if you have not net connection please provide the output of lshw (run in konsole) we should only need the network section of it (edit out the mac addresses/serial numbers) . also provide ifconfig and iwconfig (again rub in konsole). that should help us help you more.

Re: Wired Connection Not Working - HELP!

Open a console (or, konsole) and type:
lshw | grep -nA 10 network
The listing should show all the available equipment.
If the listing shows a WLAN0 or ATH0 or something
similar and says it is "unassigned" (I think that is
correct), then you need a driver. This is only guess
work on my part because that is how I found out
that my laptop needed a driver. It is not shown in
documentation I have found.
Good luck!

This will be a long posting, so first I'd like to say thanks for quick responses...

2nd)
The machine I'm setting up doesn't have wireless access.
I checked the router & cables. I'm able to connect using the same cable & my laptop running Win7.
I also tried rebooting the router a few times. I'm able to log in to my router but can't see the Kubuntu machine in the DHCP Client List.

Re: Wired Connection Not Working - HELP!

it seams to be set up correctly. but why its getting a "fake" ip address is a bit of a mystery.

"inet addr:169.254.11.130 Bcast:169.254.255.255 Mask:255.255.0.0"

thats a "fake" ip address. telling me its a cable or the routers config? i see above you tried other cables. you might also want to peek in your network port and make sure you didn't bend any of the pins in the connector. (odd as it sounds i've seen ppl do it)

check that the card has a driver assigned. (lshw ) then check to see if the driver is loaded(lsmod) if not load it w/ "sudo modprobe <drivername>" . it seams that you have it set up because you get an eth0 and eth1 (two cards?)

as a test also try to set it all up manually maybe dhcp is just not working for some reason.

searching for "RTL-8139/8139C/8139C+ ubuntu" i found this.<link below> you should look it over..replace any "gedit" commands w/ "kate" and "gksu" with "kdesudo". other then that the same stuff should apply.

good luck and let me know how it goes.
