Problem wireless connection with WPA2 Enterprise

Hello,
I am experiencing an annoying problem while trying to connect at the wireless network at the University, adopting WPA2 Enterprise. After some days of frustration I decided to post a help message here, I hope it's the right section (my problem could be kernel related...). Basically I can't connect to the network, no matter how many times i may try. Other operating systems do not give me the same problem, I can connect without issues thus my card is working properly.
Summarizing:
- My card is a BCM4313 (Broadcom), natively supported within the kernel by the module brcmsmac.
- I tried the module wl as well, with no result.
- I tried both Arch standard kernel and the LTS one.
- I am Gnome user, hence I use NetworkManager (never had a problem in the last 2 years at least...)
- I tried Wicd as well (in the past it was working when NM was failing), with no result.
- Both MS Windows, Ubuntu and Linux Mint (driver brcmsmac) allow me to connect to the network.
- The problem occurrs only in case of WPA2 Enterprise, unfortunately this is a "parameter" I cannot change...
What follows is a portion of NM log file, where I isolated the part related to one connection attempt.

As I said before, it may be a kernel related problem, but it seems very strange since I would expect a higher number of users experiencing some troubles.
As a final note, I've been Arch-dependent since 4 years already and I love it. I can't really imagine to change distribution just for this...but I am stuck at present and I need to work with the laptop, so any help is really appreciated.
Thank you

I did what you suggested and I could connect to the network, ergo it was a NetworkManager problem.
I am migrating to netctl, and I will test it at the university in the next days. I hope it will work.
Thanks for the hint, I should have done this test in the first place...:(

MAC OS 10.4.11 connecting to WPA2 Enterprise not permanently working

Hi,
I have an issue with the following environment. I will try to simply my wording to help understand the problem.
Hardware: Macbook Pro 17" Intel Core 2 Duo and Macbook laptops
Operating System: Both run MAC OS 10.4.11 fully updated (According to Apple Reps, this operating system is no longer supported)
Airport cards: Both have Airport Extreme cards. The Macbook Pro's card is using Firmware version 1.4.4 ( card type requirement to connect to WPA2 Enterprise network)
Connection type: Connected via PEAP (Inner Protocol:MSCHAPv2)
Wireless Access Point (WAP): Cisco Aironet 1142: Macbook connects to WAP to gain access to the Internet.
Cisco ACS version 5 server (validates macbook username and password entries to Microsoft AD servers.)
Microsoft Windows Server 2003 with Active Directory (holds user accounts)
Other Operating systems MAC OS 10.5 to MAC OS 10.7 (Leopard, Snow Leopard, and Lion make automatic connections.)
Basically, the process is that the macbook user enters in their email username and password into a WPA2 Enterprise wireless connection. The Cisco 1142 broadcasts the SSID for the user to connect to. Once the wireless connection is made to the Cisco 1142 WAP, the WAP sends the username and password to the ACS server. The ACS server verifies the username and password from the macbook to Microsoft Windows Server AD user accounts. If the password is validated, then the ACS grants access to the wireless Internet to the macbook user.
The wireless configuration involves the following process:
1. Click on the desktop, Go should be available now.
2. Click on Go, then Applications. The Applications window will appear.
3. Click on Internet Connect.
4. By default, The 802.1X connection is not available. We will be using the 802.1X connection to enter and save the username and password. Click on File and select "New 802.1X Connection."
5. A windows should appear. Under Configurations, select Edit Configurations.
6. An 802.1X windows will appear to enter in the following:
- Description: name of connection
- Network port: Airport
-User Name: domain\username or just username of email account
-password: password for email account
-Wireless Network: SSID of Cisco Aironet 1142 Wireless Access Point (WAP)
-Authentication PEAP configured with outer identity of anonymous. We uncheck TTLS, EAP-FAST, LEAP, and MD5.
7. Click Ok. Select Connect and it should connect to the SSID if the username and password are valid accounts.
8. Select File and then "Export 802.1X Configuration to login Window."
To verify connection:
1. We go to Apple - System Preferences and select Network.
2. The Airport should say that it is conected to the SSID. You are connected to the Internet via Airport.
3. Go a little deeper, we click on configure for the Airport.
4. Under By default join: select Preferred networks. Under network name, we should see the SSID connection. We select it and click on the edit button.
5. We verify that the connection has Network Name, Wireless Security, User Name, Password, and 802.1X Configuration entered in correctly. We select Ok after verification or modification. Then we select Apply Now to save any changes.
---------------------------------------------------------------The Problems---------------------------------------------------------------------
1. When shutting down the system and then turning it on. The Airport doesn't make a connecation to the SSID being broadcasted automatically. We would have to turn the airport off and back on for it to make an connection.
2. When the laptop is left idle or goes to sleep, the wireless connection drops. The user would have to turn the airport off and back on to stay connected.
Is there a fix for this?
Thank you to anyone that would take time to read this and provide helpful feedback.

The "v" key at startup is not Safe Mode. Try holding the Shift key down and restart for Safe Mode. This will disable extensions and help it start. It also checks some things out.
Can you start it up from your Tiger disc? Hold the C key down at startup until you see the Apple.
Your hard drive may be going kaput. Hope you have a good backup.

Wifi problem after.4.3 update on xperia z

Hi all,
After updating my Xperia Z (C6603) to build number 10.4.1.B.0.101 I've been having connection issues with every Wi-Fi network.
I've checked the forum but I only found problems about people having Wi-Fi issues with their smartwatch, I do not own a smart watch this is just a general networking issues.
Here's the problem in detail:
When having no Wi-Fi switched on while booting the phone the phone will start without any issues, I will receive my 3G/4G signal and I can browse, e-mail, everything.
Once I switch on Wi-Fi it will start connecting to previously stored Wi-Fi access points but will not connect. Eventually it says that there was a problem with connecting, even though this will take several minutes.
I can go into the Wi-Fi settings, select a different Wi-Fi network (if it is in range) and press connect, however the settings app will freeze at that point and eventually I'll get a notification that the settings app has stopped working.
I have found a "work-around": I switch the Wi-Fi to on, power off the phone and power on again. Now the Wi-Fi connection immediately powers on without an issue once the phone has completely booted, it also will connect to the default Wi-Fi connection that is in range. A different issue appears however once I move out of Wi-Fi range, it will no longer pick up my 3G/4G signal. It is also impossible to switch off Wi-Fi or switch Wi-Fi network connections without rebooting the phone.
As I said before this happened to me after updating to version 10.4.1.B.0.101 after having it received through OTA update. I do not have root access on my phone either so this can't be it.
Is there anyone experiencing the same issues? Is this somehow related to the issues people are experiencing with their smart watch connections (as seen in this topic: http://talk.sonymobile.com/t5/Software-Updates/wifi-problem-after-4-3-update-on-xperia-z/td-p/490591...
If there's anyone who is experiencing the same issues, or has found a fix for this I'd gladly hear from you.
Regards,
Danny
Sony Xperia Z
Modelnumber: C6603
Android version: 4.3
Kernal version: 3.4.0-ge09aff8

I faced the same problem. So what u did now to connect your 3g or 4g. Did u tried kitkat update? Its works or not?

LEAP WIFI problem after updated to 4.2.2

I've just upgraded my tablet to 4.2.2.
Now I can't connect to my company's network which uses password LEAP. Major problem for me.
Seems this is a common problem across a number of Android platforms.
Does anyone know how to resolve on the Tab Z (not rooted). ?

We are looking into this (see http://talk.sonymobile.com/t5/Xperia-Z-ZL-ZR/XPERIA-Z-LEAP-WIFI-problem-after-updated-to-4-2-2/m-p/3...) but at the moment i have no solution. This seems to be a general problem with Android 4.2.2 from what i've been able to find.

Since I upgraded to Moutain Lion I'm dealing with wifi problems : no connection or random connection

Since I upgraded to Moutain Lion I'm dealing with wifi problems : no connection or random connection. With OS X Lion wifi was OK.

So, Darrall, it seems to be fixed. Mind you, this has happened through a seemingly unrelated, but hopefully replicable sequence of events. You be the judge.
I went to my other login account, which as it happens is also an admin account. Voila, the secondary click worked fine. So I returned to my primary account, where I did the following:
First, I unpaired the trackpad. then I remembered I needed something to move the mouse with, so I re-paired the magic mouse I'd had before. I thought I'd turned off the trackpad, but apparently not, so the computer re-paired it automatically. None of this had any immediate effect, as you'd imagine.
Then I went to Mission Control in Preferences. There, I deselected "Show dashboard as a space", and in the hotcorners, I deselected Mission Control from the bottom left, where it had been. I didn't replace it.
Now, my secondary click works. Uh huh. I was suspicious that it might have more to do with Mission Control and/or Dashboard than the trackpad, only because I'd beaten that horse till my arm hurt and this was all I could think of.
Never did I imagine this would get fixed short of creating a new login account and somehow copying everything - since I didn't know what was wrong, I could easily have copied the error too - so I'm very pleased and relieved. If you haven't fixed yours yet, try this. Let me know what happens!

There are many threads in the OSX Lion section describing wifi problems with 10.7.3 in general. Personally, I am experiencing wifi drops when my iMac wakes up from sleep. The issues are not isolated on the MacBook Air, but seem to be affecting all Apple products running 10.7.3.

WiFi problem after upgrading to Windows 8.1 Lenovo R400 ThinkPad

I have this problem after updating to 8 to 8.1
Right after updating to 8 to 8.1, all of a sudden my wifi stops working. I used my philips external wifi usb stick and now I'm able to get the internet going.
However if I disconnect my philips usb I no longer get the internet because the built in wifi that came with the R400 ThinkPad no longer works. I went through the device manager and under properties it tells me, 'Device not working properly' however it is up to date.
Im Running Windows 8.1 64bit Laptop Lenovo R400 ThinkPad

Hi Matti,
Thank you for replying back!
I suggest you to reinstall the Windows 8.1, as all the windows driver will not update, if you have upgraded the Windows 8 to Windows 8.1.
Please download Windows 8.1 separately and reinstall the OS, I hope this may resolve the issue.
Note: I am not suggesting for clean installation, only reinstalling the same OS.
Do not update the drivers from ThinkVantage system update utility. I suggest you to uninstall the current drivers and download the drivers manually for Windows 8.1 and install it.
Below is the link to enter the downloads page and download updates accordingly, please click on "Select Product" then in "QUICK PATH" enter the MTM no. select the exact model.

Wifi problems after update airport configuration

Hello, i have a question about my wifi. After i installed airport configuration 6.1 my computer said there is no wifi hardware installed. Does anybody knows how to fix this?
Or to get back to 6.0 ?

Thank you.
The problem is that I used to have a wifi network that let me go on the internet from my iPad, iPhone and laptop. Two days ago, it disappeared: no access to the internet via wifi from anywhere but my desktop. The old wifi network isn't listed anywhere, on my desktop or other devices that detect wifi.
I access the internet via ethernet from my desktop, via virgin media.
What I want to do is get a home network up and running again. Originally, it was all automatic - I didn't have to know anything to get it working. Then I followed some nifty spec on the forum to slightly alter the address of the device, and my other devices, so that I could use my computer's wifi from my Kindle. For the next 9 months, no problems. Then I casually updated the airport utility and poof, the wifi network vanished. And I don't know how to get a DHCP ID or anything else, because I didn't have to do it originally. I just plugged in my computer and did what I was told to.
This sounds so pathetic. I'm sorry. Is there some way I can just start all over again?

Ipad Wifi problem after 7.1.2 update

Hey there! I noticed a big problem after updating my Ipad Air (Wifi Only) to iOS 7.1.2
When I put the device on standby It disconnects from the Wifi network, so I don't receive any push notification. Then when I start using the iPad again, the device reconnects immediately to the Wifi.

Try this - Reset the iPad by holding down on the Sleep and Home buttons at the same time for about 10-15 seconds until the Apple Logo appears - ignore the red slider - let go of the buttons. (This is equivalent to rebooting your computer.) No data/files will be erased. http://support.apple.com/kb/ht1430

Wifi problem after updating my phone to ios 7.1.1

Hello everyone ,
I seems to be having wifi problem on my Iphone 5s. Before I updated my iphone to IOS 7.1, the wireless works just fine and without any disconnection. But now since i updated my phone to 7.1, my phones keep getting disconnected or hardly could connect into it. Sometimes when i go into the wifi setting, it detect the wireless but it says "Unable to join the network". However I'm using the same wireless connection on my laptop in the same location where i stand and my laptop wifi connection work just fine and smooth. What could be the problem? I need a solution.
I've Tried to put it on Airplane mode and reset network settings but still unable to solve it out. Secondly i also tried to reset all setting and hold both home and power button. Nothing is solving this. I need a solution, help please society :')

I am having the same problem since updating to 7.1.1. I also would appreciate any help.
I have tried the airplane mode and reset network settings with no luck.
Thanks in advance for any solutions provided.

Problems after connecting USB 1.1 devices to an unpowered USB hub

After connecting a mouse, usb stick and an external hardrive to an unpowered USB 2.0 hub, I now get no response from any of those devices, though they had been working fine before. Other devices that I have since plugged into that same usb slot work just fine. What could possibly have happened??? I appreciate any insight!

Nance,
Welcome to the Discussions.
You did not mention if each one of these devices still works when plugged directly into the USB 1.1 port. If they do, then I cannot explain the problem. If they do not, it is possible the USB 1.1 port was overloaded with all three devices connected to the unpowered USB 2.0 hub. You may have gotten such a warning on the screen.
If you have not done so, I would disconnect all devices, shut down the powerbook, then reset the PRAM.
http://docs.info.apple.com/article.html?artnum=2238
Now test each device by connecting directly to the USB 1.1 port.
If both the USB stick and USB HD (I am assuming that you have an unpowered 2.5" HD) were mounted on the computer's desktop when this 'possible' power shortfall occurred, it could have corrupted both devices so they will not longer mount properly. Connect each device to the USB 1.1 port, then see if Disk Utility can see the device and repair any damage. The mouse may no longer work if the preferences or other software was corrupted.
If you are running an unpowered HD, I would recommend a powered USB 2.0 hub so you can connect other devices without worry.
