Re: KUBUNTU 10.10 HELP WITH NETWORKS

start by opening a terminal, typing ifconfig and iwconfig and then search this forum for solutions.

See the ReadMe link in my sig also...

Re: KUBUNTU 10.10 HELP WITH NETWORKS

Welcome to the forums wrxfifer!

Actually the problem is likely trivial, but there is no information on which to base an answer. The output of ifconfig and iwconfig will give some specifics. The "red cross" just says it isn't on - nothing more.

As for the 40 views, I have a number of forums and web sites on line and I still can't figure out what that number really means. In this case probably a member or two had a look but didn't feel comfortable with networking, and the other 30 something are random hits off the net - maybe also some bots.

BTW: the "ifconfig" command is almost the same as in MS-Windows where it is "ipconfig".

Edit: Oops, I forgot to address your "command line" comment. I'm not sure if you're kidding or not, but the answer is yes.

You open a terminal by clicking on an icon that looks like a monitor. It will probably say Konsole. Then you can type the word "ifconfig" and it will respond with information about your network. The same goes for "iwconfig" which is about the wireless. This is way faster and easier than clicking on stuff and much more informative as well as 100% reliable, which is particularly important when troubleshooting.

Re: KUBUNTU 10.10 HELP WITH NETWORKS

Hi Grant

Can you open up a terminal and type

Code:

lspci

That will tell us what ethernet and wireless adapters you have.

Unless you have an obscure ethernet card, simply plugging in an ethernet cable ought to produce a connection. That might be important, depending upon the output you get from the terminal with the above command.

Re: KUBUNTU 10.10 HELP WITH NETWORKS

Okay

You need to be running a wired connection.

I'll minimise the command line use - excessive exposure at the start can put newcomers off.

Open the package manager kpackagekit

Then select the software updates tab then check for updates. That will generate a full package list as at this point I think your computer probably only knows about those on the CD.

You can then install the updates at this point if you want - there will be a couple of hundred updated packages. Whether or not you do this you then need to select get and remove software and in the search box type b43 and you should see the package b43-fwcutter package. Select the package and click install.

Follow the instructions here
https://help.ubuntu.com/community/Wi...0b43%20drivers

Once installed reboot and your wireless should work

Re: KUBUNTU 10.10 HELP WITH NETWORKS

also if i stick an ethernet cable in nothing happens? nothing in network manager everything still greyed out etc?

**wrxfifer** · Mar 08, 2011, 09:21 AM

Re: KUBUNTU 10.10 HELP WITH NETWORKS

i assume thisis because the network adapter is not working either

Re: KUBUNTU 10.10 HELP WITH NETWORKS

Everything I have read about this laptop suggests there should not be a problem connecting with an ethernet cable.

Was the cable plugged in before you rebooted?

I wonder whether for some reason something has happened to disable the network manager (in which case you won't connect).

In which case please try this (in a terminal)

Code:

sudo service network-manager stop
rm /var/lib/NetworkManager/NetworkManager.state
service network-manager start

You will be asked for your password (sudo is the comand you use to raise your level to administrator).

Once you have run that, assuming no error messages, do you have ethernet?

That will happen if you have no network connection

Re: KUBUNTU 10.10 HELP WITH NETWORKS

right i dont know if this matters and am trying here lol, thanks for helping it's very appreciated, at the point of install etc no ethernet cable was connected just power supply after installation complete there was 3 things that was preffered internet connection being one of them which i assumed i did not have? no drivers etc

so before i plugged in ethernet cable just now i tried what you said and got this lock message? then decided to plug in in as i would normally for any other wired connection in my house from laptop direct to my router/modem this registers nothing on the laptop nor does the specific port on the router light up as it should to say its in use? have tried all 4 and all the same? i can confirm my network/wifi/router/modem is working fine 100%
