No more wireless router options in right click menu, "wired" icon showing in tray

how can i should i go about fixing this problem still new with linux os really can us the help appreatiate it

Hi James,

Sounds like a lot of stuff has gone wrong for you, and perhaps you're going to end up spending longer fixing things than it'd take to reinstall Ubuntu from scratch.

Because you can't run the latest install of your kernel, it sounds like you have serious problems (because the kernel is the core of the operating system). If you aren't really that experienced with Linux yet, and as long as you don't have anything stored on your computer that you'd hate to loose (although you can always back it up over your network first) it might be easier to simply do a fresh feisty install.

In my opinion, you'd be better off doing a fresh install of feisty than go from dapper > edgy > feisty anyway mate.

OK, my name isn't James, it's Paul. I don't know what that was all about with James up there.

Anyways, I guess I'll take your advice and do a fresh install. There are a few programs (like Skype for Linux and Teamspeak for Linux) I'll have to reinstall - is there a way to actually back up programs or is this impossible? I know I can do it with Teamspeak because that was just an "extract to location and run in terminal" type of thing.

I'll start backing up my business and school files to my USB drive.

Are there any specific steps to take before I re-install, for example: doing anything with the partition (there is a another partition with Windows that broke itself, and I keep it for some old files that didn't get deleted in the "Big Chkdsk Swipe") and how should I clean off the old Ubuntu OS after I back everything up?

Sorry Paul, :-)

The poster (called James) above my reply said "how should i go about fixing this problem...." I assumed he'd posted the original thread!

I'd be inclined to install TS and Skype from scratch to be honest.

Skype have got a debian repository, so if you go to | add/remove applications > preferences > Third Party Software > add | and put in this repository:

deb http://download.skype.com/linux/repos/debian/ stable non-free

You'll be able to install skype from add/remove apps or via sudo apt-get install skype . If you do it this way it'll also update when there's a newer version.

Whether you want to use your full disk for Ubuntu and get rid of your other partition, or leave things as they are, running the installer lets you choose a partitioning format. Its in a wizard format and fairly self explanatory so you should be fine.

Hope that helps you get sorted, and hope you enjoy Feisty.

Cheers

Chris

Just double checked the skype site, and they don't seem to have that
repo there anymore.

You can still get it from here though.

http://www.skype.com/download/skype/linux/

I forgot one command though - I tend to use Kubuntu a lot (I installed it through Ubuntu). What's the command to do that again, and I assume that will install the 7.04 version of Kubuntu?

On Skype: I think that's where I got the install file from in the first place - thanks.

I don't use the KDE variant myself, but I believe that

sudo apt-get install Kubuntu-desktop

should do the trick

I know how you feel, I was a Windows only sysadmin not so long back.
I've turned away from the 'dark side' now though :-P - The more you
use it, the easier it gets!

Have fun

Chris

And sorry I meant

sudo apt-get install kubuntu-desktop

not Kubuntu-desktop

A cool command is

sudo apt-cache search WhateverYourLookingFor

Ah ok, so it's case-sensitive.
Thanks for that and the tip!

OK. I'm having a bit of trouble now with the install. What do I do for the partition? It asks me to partition the Linux partition with the slider, use the whole disk, or Manual. Manual won't do anything for me, it keeps saying I haven't selected a root system or something. Do I do the first option but move the slider to 100 or does that create a 0 byte partition???

I learned that using the Guided with the slider leaves the 2GB for the Linux that's already on there - I don't want that anymore. I want to completely overwrite that partition and use it for the new installation. In Manual I selected the Format checkbox for the correct partition but when I do that, it still says I haven't selected a root. Am I supposed to select Format as well as changing "/dev/sda2/" to just "/"? It says in the little note that you define the root system with a forward slash.

OK, I did some research and the install was successful but I am having one problem so far.

When I go to connect to a wireless network, it refuses to connect. I did a manual configuration and that wouldn't work either. At times, if I tried pppoeconf when it was trying to connect to the router, the system would hang and I'd have to force the computer to shut down. Eventually I tried going quickly from a Manual to Roaming connection and it then the icon said it was connected. However, there is no IP information. Everything is 0.0.0.0. I would assume this has something to do with DHCP not working right. I haven't tried wired yet.

I just rebooted and now it is not showing any wireless networks.

I'm using a Linksys WPC54G card which worked before I did this fresh install.

Keep in mind that I installed via another laptop by switching the hard drives. The laptop I use doesn't have a working CD drive.

Hi Paul,

Run this command, it'll show the network devices on your computer:

sudo lshw -C network

Find your network card, copy and paste the info back here.

Also try this command:

iwconfig

And paste the output of the command back too please.

In fact - If you're feeling brave there is a full tutorial on
troubleshooting wireless problems in Ubuntu here ;-)

OK,

So your output shows that you have drivers installed, your wireless
card is up and running, you can see the access point (although the
signal's not great) but you're not associated with the access point.
You need to get associated with it.

Personally, I've had a couple of issues with activating the 'roaming'
option in the NetworkManager applet. What I suggest, is that you go to
administration > network, select the wireless connection, select
properties and fill out the fields manually.

You'll need the ESSID name from the iwconfig output. Enter that
manually, put it on DHCP make sure theres a tick/selection next to the
wireless card.

Restart your computer/router if that doesn't work straight away.

You can give the command ifconfig to see if you've been issued with an
IP. iwconfig will show you if you're now asscociated with the AP.

Cheers

Chris

I tried using Manual mode and that didn't work at all either. After I switched from Manual to Roaming and it showed some kind of "fake" connection, there was still no IP address assigned by the router.
At this point, I can't even select a network to connect to because they're not showing.

I just tried Manual again and there's no indication from the network manager icon that I'm connected, but ifconfig says I have a LAN address (woohoo! now if it would do it on its own...)
I'm going to re-run pppoeconf because my ISP uses PPPoE. OK just did that (I'm doing things as I type here). I started the PPPoE link and I was able to get on google.com. I'm gonna run the Update Manager to see if there's anything the computer needs.

I'm seeing this exact same problem. One moment my wireless was working and the next knetworkmanager doesn't show any wireless networks.

I can see the network using iwlist

I can see packets on the network using kismet

I can't acquire an IP address using DHCP, and I'm having trouble associating with the access point.

I tried turning off WEP at the router and now I can connect to the Internet using iwconfig and dhclient but knetworkmanager STILL doesn't show any wireless networks.
