[UBUNTU Studio] Can't connect to internet via Wireless

**DivinityX** · May 24th, 2008

So I just installed UBUNTU Studio 8.04 on my computer and I'm lovin everything about it except...I don't know how to connect to the internet, much less my router...someone please help me out

I have a:
Linksys Compact Wireless-G USB Adapter
Linksys Wireless router in my other room, with no password security

also, could someone explain to me why it's so much easier to connect with plain UBUNTU rather than UBUNTU Studio?

We'll need to have a look at some things first. Please post the output to:

Code:

sudo lshw -C network

Code:

cat /etc/resolv.conf

Code:

ifconfig

Code:

iwconfig

Code:

iwlist scan

Code:

cat /etc/network/interfaces

Place the output in quote marks please. 4th button in from right on toolbar.

So I just installed UBUNTU Studio 8.04 on my computer

The output you have posted (thanks!) does not look good. Did you have this machine running OK (i.e access to internet) under a previous version of Ubuntu?

**DivinityX** · May 24th, 2008

Normal UBUNTU (which i'm running right now) is just fine. My computer has 3 Hard Drives, a 20, 40 and 80 gig, which each have an OS on them...

(Pri. Master) 20G = Windows XP Pro

(Sec. Master) 40G = UBUNTU 8.04 & UBUNTU Studio 8.04

(Pri. Slave) 80G = Windows XP pro

By defalut, UBUNTU Studio runs. (which I do not want to happen)

On the 20G I've been experincing major slow down but I believe that is due to the lack of mem left on the HD, Internet works fine. Doesn't always want to shutdown, very few crashes

On the 40G, it has been partitioned in half to put two OSs on there, UBUNTU works fine, it has a tendency to freeze (Which I believe is because of RAM or Graphics card) rarely the screen goes black and the sound cuts off but the computer still runs (or at least it sounds like it does) Internet works great.

On the 80G, I haven't used its OS in awhile, because I only have it for storage and back up, but it works perfectly fine along with the internet.

So yeah, in case you need to know, here's the other Hardware on the computer...

RAM = 1GB
CPU = 3GHz (Intel Pentium IV)
Video Card = (not quite sure, I lost the info, but I know it's ATI and it works pretty well in my standards...)

I hope this info helps...

i am having the same problem. I can hardwire in but cannot get wireless access. I can see the my network but everytime i try to connect, i get connection failed cannot obtain ip address. I am using ubuntu 10.10 and this is the first time i have used a linux os. I have read some of the posts so maybe some of this info can. I have been trying to figure this out for two days. It's really beating me down.
