View Full Version : [ubuntu] [SOLVED] WPA Security Troubles
January 4th, 2009, 06:58 AM
I had some trouble in the past with the wireless, so to eliminate confusion, I disabled the wireless security settings in my router.
With your help, I got my wireless internet up and running on my Ubuntu laptop. I have decided to re-enable the security settings on my router to protect my wireless network from wardrivers and crappy neighbors.
Now, I am unable to connect to my (now) WPA2 wireless network. I would like your help in troubleshooting my problem.
Dell Inspiron 1721
AMD TL-60 @ 2.0 Ghz
2 GB DDR2 667
250 GB HDD
Dell 1505 Draft 802.11N wlan mini card
Broadcom BCM4328 10/100 network controller
PS - PLEASE DO NOT point me to several web pages for help. I am a newbie, and still learning, so link after link, page after page of different codes and commands can be a little confusing and frustrating.

A couple of thoughts.
Have you tried using other password protocols. I remember reading somewhere that WEP often worked when WPA did not.
I'm assuming that you can still access your router through a wired line.

That is correct, I can connect through a wired connection.
So far I have tried WPA and WPA2, both personal.
I will try WEP and report back.

Apparently, my card won't get along with WPA or WPA2 personal in Ubuntu.
GOOD NEWS: WEP works just fine.
I am debating on MAC filtering, but I'm still on the fence.
Thank you so much!
