When I use my laptop running Ubuntu 12.04 as hotspot, I am only allowed to use WEP security instead of WPA.

I dual boot Ubuntu with Windows on this laptop and when I use Windows to create the hotspot I am allowed to use WPA security so it is not a hardware issue.

  • I use Intel PRO/Wireless 3945ABG wireless connection.

I've seen this problem on many different hardware configs, starting a bounty. – int_ua Jun 14 '12 at 13:46
I think it would be better to cut "with an Intel 3945ABG" from the title as it's not just this card affected. – int_ua Jun 14 '12 at 15:06

I researched for an answer for almost an hour, and was unable to find anything. It appears that the ubuntu built-in hotspot service doesn't support WPA.

(I could be wrong; in fact, I hope I'm wrong. The built-in hotspot service should support WPA, and if it doesn't then they should definitely update it.)

At this point I think the only way to create a hotspot with WPA security capabilities would be to use third-party software.

The other option would be to use WEP. It has some serious problems as far as security, but if security isn't a big concern then it could be an answer.

Choose wep 40/128 mode, not Wpa. Detail info:

While this might be a good answer to the question it is important to add the information from the link you supplied in to your answer. Answer that are mostly composed by a link do no belong on the site. – Bruno Pereira May 27 '12 at 8:51
Also, WEP is extremely insecure (regardless of the key length or password length/randomness)--if any form of WPA is available, that should almost always be used instead. (If security is not important, unencrypted wireless can be used instead...) – Eliah Kagan Jun 14 '12 at 17:08
