How To: Manual Network Configuration without the need for Network Manager

[kevdog]

Where are you getting the 28% stuff -- From the command line Im not familar with that output at all.

What is in the lscmnds subfoler??

There is an icon in the tray where you can click to connect to a wireless network. When I tell it to connect it starts connecting until it gets to 28% and then fails. It does this on any wireless network, not just my router.

followed all the directions step by step, but I'm still getting "No DHCPOFFERS received."

No icon is involved in these instructions -- if your having a problem with the icon, these instuctions are not for you!

I see that you are getting no dhcp offers. What is the sgnal strength reported for your router for

iwlist scan

 Quality:76/100 Signal level:-47dBm Noise level:-96 dBm

anything??

I am not using the icon with these instructions. It won't connect when I follow the instructions. When I use the GUI to manually set addresses, DNS, and Gateway or if I set it to automatic, there is a Icon to click to see available wireless networks. I can see the network, but when it tries to connect it only gets to 28%.

Here is the scan

I wish I could help you guys more, since it seems like you guys are doing everything right. Ive seen random problems like this before, and its always something I would never think to do that would fix it -- like uninstall a different package, or disable ipv6. Try disabling ipv6, not sure if this is going to help. Ive also seen some cards struggle with 64 bit wep (some driver problem) so I dont know if you are effected by this. Have you tried ascii based wep authentication:
sudo iwconfig wlan0 key s:ASCII

With WEP, are you using the first hex key??
You can set your key index with the following command:
sudo iwconfig wlan0 key [1] XXXXXXX (or s:ASCII) key [1]

Here's one for you.
I have two identical network cards. (ipw3945)

One is working A-OK.
The other is showing up in the system, but with no logical name, and no mac address. I've checked the wireless switches, bios settings for the card - and it is enabled...

Here's what I get for "lshw -C network"

*-network

Obviously - the bottom one is working, top is not.

Where would I even start to get a logical name assigned to this. Querying "dmesg" doesn't give me anything interesting (errors) about this card.

I've tried other forums, threads, and this is the closest one I could find relevent. ANY help at all is appreciated.

Thanks.
