I am picking wireless networks near my home but I am having issues connecting to mine? Under the KDE gui setup it only lists WPA and WPA with TKIP but not WPA2 with AES. Is there a GUI feature that I am missing? Is there a flat file that I can alter to configure wireless for my laptop?

If you want to use configuration files, then you need to use YaST to
convert to “traditional ifup” control, which turns off NetworkManager.
You will also need to prepare a configuration file for wpa_supplicant;
however, this should not be necessary. The scan data for my system is
as follows:
That configuration was done with the NetworkManager GUI. Just
configure the connection with WPA and enter your PSK. The code is
smart enough to figure out that it needs to use CCMP (or AES).
I’m all about using the GUI especially coming from a windows background. I changed my wireless settings back to WPA2 with AES and I still can not connect by using the default WPA setup with my shared key. Are there any logs I can look at to see if the laptop is even trying to associate to the AP? I was not broadcasting my SSID before so I turned that back on but I still can not connect. I have 4 windows workstations that are connecting to this SSID with WPA2 and AES with no issues:\

If you edit
/usr/share/dbus-1/system-services/fi.epitest.hostap.WPASupplicant.service,
you can change the options used to start wpa_supplicant. I would add
-ddd and perhaps -K. The man page for wpa_supplicant will show you
what these do. After you do that and restart NetworkManager, the log
for wpa_supplicant should help you.
I added -ddd and -K but this is all I am seeing in the log:
> tail -f wpa_supplicant.log
CTRL-EVENT-DISCONNECTED - Disconnect event - remove keys
CTRL-EVENT-DISCONNECTED - Disconnect event - remove keys
CTRL-EVENT-DISCONNECTED - Disconnect event - remove keys
No network configuration found for the current AP
CTRL-EVENT-DISCONNECTED - Disconnect event - remove keys
CTRL-EVENT-SCAN-RESULTS
CTRL-EVENT-SCAN-RESULTS
CTRL-EVENT-SCAN-RESULTS
Does it matter if I broadcast my SSID? I am seeing about 10 SSID’s in the neighborhood I just can’t see mine but then again I am not broadcasting it. I deleted the wireless network profiles and re-created them but it still did not resolve my issue.

Turning off your SSID broadcast greatly complicates the process of
connecting to the AP and provides NOTHING to the security. With a
packet sniffer such as kismet or wireshark, I can get your SSID within
30 seconds even if it is hidden.
If you want to keep it hidden and use NetworkManager, you need to
research how to connect under those conditions.
So if a SSID is hidden you can’t connect to it even if you specify the proper credentials? Cisco AP’s by default hide their SSID name.
Remember most people are not using kismet and wireshark, I guess I’m protecting myself against the average Joe plus it is just a good security practice. Am I still subject to a drive by war driving, sure.

The average Joe is discouraged by WEP, even though it can be broken in
5 min, or less. Using a high-strength WPA PSK, or even better WPA2,
greatly improves your security.
Although you think hiding the ESSID is good security practice, I think
it leads to more interference. Why? What is the first thing I do when
I set up a new AP? I scan the neighborhood to find the channel in the
set of {1, 6, 11} that has the fewest, strong signal AP’s on it.
Hidden ESSIDs skew the data, and may put my AP right on top of yours,
with both of us losing throughput.
You can. But it’s much more complicate to configure …

I’ve seen these kind of discussions a lot of time.
3 year old kids think they are hidden if they just put their hands on their eyes … that’s similar if you hide your SSID … and block foreign MAC addresses …
Use a safe encryption algorithm (WPA or WPA2) and a secure PSK and you don’t have to worry about any attacks.
Ok, I enabled SSID broadcasting and I still cannot connect:-\ Where is the config file that stores my wireless settings? I went through the wizard and put in my SSID name, then I selected WPA Personal, then I put in my Shared Key and then hit OK. Are we sure the wizard configured WPA as WPA2 with AES?
So as I was troubleshooting anytime I would enable any security my wireless network would drop out of my network manager listing in my task manager. I tried WEP and WPA with no luck:\ I disabled all security and said to auto connect and it still would not. Will wireless not connect when your LAN jack is active? All the testing above was done on a spare AP that I had sitting around.
So I disabled security and I am broadcasting my SSID and I still can’t connect…
Here are my settings with just WPA setup and I have all adapters setup for DHCP and I tested the wireless SSID setup with my windows laptops with no issues reported.
Will wireless not connect when your LAN jack is active?
no it won’t,unless you have the ethernet set to on cable connect. In which case, unplugging the ethernet will allow wireless to connect/scan
Thanks for the links but can anyone help me with a Manual driver install? Do I need to compile it from the CLI? Remember I’m a windows guys so I will need a little help getting the driver loaded. I have tried ./INSTALL with no luck:\
compiling is fairly easy,after you’ve done it a few times. Firstly,you need to have the basics installed,kernel sources,make,gcc/gcc++.Then,read any readme which came with the file for any special instructions. All are done from the cli. A couple of how-to’s here:-
Wow as I am reading the Install files it’s making my eyes bleed. I have been working for days trying to get the sound and wireless working and now I’m almost 100% frustrated:\ I basically have to build a new driver into the kernel… You would think there would be an easier way. All it takes is one rogue kernel update to blow away hours or days worth of work.
I started to build the ieee80211 new subsystem but that didn’t work so now I need to remove it, I think?
-lo
First, we build and install the ieee80211 subsystem. You can obtain
the latest ieee80211 subsystem from ieee80211 subsystem for Linux. We
recommend version 1.1.12 or newer:
% tar xzvf ieee80211-1.2.16.tgz
% cd ieee80211-1.2.16
% make
# make install <--- You may need to be root
% cd ..
If you encounter problems with the above, you may need to install the
ieee80211 sources into your kernel and then build it as part of your
kernel image. See the INSTALL and README.ieee80211 file.
My Error:
ieee80211-1.2.18 # make install
make -C /lib/modules/2.6.27.23-0.1-pae/build M=/home/lodogg/ieee80211-1.2.18 modules
