I am having problems with wireless connections


Hello:


I have installed ubuntu 10.10 notebook Edition on an ASUS
M5200N notebook.

iwconfig
lo no wireless extensions.

eth0 no wireless extensions.


eth1 IEEE 802.11b ESSID: "rmhsnew"
#######
#####
#####

I don't know how I should enable the wireless connection.
This machine was given to me by someone for free. The previous owner had Win XP installed on it and worked just fine for wireless connection.
Everything else works well on it. I have wired connection to internet.

Can you post the outputs of ifconfig, lspci, and lsmod? I want to see what kind of chipset you have, what drivers are loaded, and what all is being configured in ifconfig. Thanks,

Josh

You can fix the disorganization by editing your post and using code tags.

Now as far as your wireless, issue the following command as root:
Code:
ifconfig wlan0 up
If that succeeds, then issue the following to see if you can scan for networks:
Code:
iwlist wlan0 scan

I don't know how to do it.
But do you have all the info you needed?

Yes I do. Read my previous post though.

And as far as editing your post, click "Edit" and use code tags as such:
Quote:
[ code ]
[/ code ]
(Remove the spaces from the code tags)

OK.
As root I did:

root@ubuntu-notebook:~# ifconfig wlan0 up
wlan0: ERROR while getting interface flags: No such device
root@ubuntu-notebook:~#

Try using ifconfig eth1 up instead, since your iwconfig listed eth1. I hate when wireless settings use eth*....

OK, I had google page appearing and then never came back again.
I am back on square one.
Actually I also bought a USB stick Adapter(D-Link DWA 125) 2 weeks ago, and still can take back to store. But so far hasn't worked either. I can try connecting that also.

Run ifconfig eth1 up again, then after you do that, run ifconfig and iwconfig and post the outputs. What it looks like is that it don't have the proper configuration to initiate.

By looking everything over, it seems you should be good. You have the proper drivers installed, and they are listed in lsmod. Run the following just to be sure that all of the drivers for the module are loaded:
Code:
modprobe ipw2100
Overall, you should be good though. Use network manager and see if it will let you connect now, and report back if it works.

Good Morning Josh:


Yes, I have internet now through wireless connection.
I enjoyed the whole experience, and learned a lot from you.
Well done.

Thank you so much.
