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

[kinrose]

Are you sure your interface is eth0 -- that is usually the ethernet wired interface.

Hi, MeThinks I was confused by our Eee's which show ath0 as the interface.

I have re-run the instructions several times and now have the message:
No DHCPOFFERS received.
No working leases in persitent database - sleeping.

Best advice

Figure out the interface
Try an unencrypted connection
Use an ESSID with only letters or numbers -- no spaces or crazy characters.
Broadcast the Essid

Make sure you can see your router with
iwlist scan

Hmm. maybe you could provide more info.

I put "sleep 20" in, and still nothing.

I tried it again manually (deleted the commands out of rc.local) and it does work that way. But when I enter the line "sudo wpa_supplicant -w -Dmadwifi -iath0 -c/etc/wpa_supplicant.conf" with and without "-dd", it either goes in a loop or just sits there without returning back to commandline. I then open up another terminal, type the rest of the commands, and voila, it connects. Could this be the problem when rc.local runs at boot?

[kevdog]

Can you try with a -Bw flag instead of a -w flag? B sends it into the background. Not sure if this will make a difference in your case.

[tornsolitude]

It worked! Thank you so much!

[kevdog]

Does it work without the sleep statement and only the -Bw flag?

[tornsolitude]

Yes, I took out the sleep statement and used -Bw.

Do i need to do something else?.

Thanks in advance.

Brilliant!! I love you!!
It's so great to go back to the very basic level, that's why I love Linux when things aren't working you can start from scratch and build them up.

Thank you!

What's the problem?? -- We are not using the /etc/network/interfaces file in this example. -- neither does wicd.

Did you type any commands on the command line?
