WiFi Devices not connecting to WLC 4402

Hi All,
I have a WLC 4402 running on s/w version 7.0.240.0. Currently devices are reluctant to join the controller.
I am getting continuous log shown below
%DHCP-3-SEND_OFFER_FAIL,
%DOT1X-3-MAX_EAPOL_KEY_RETRANS:
and Decrypt errors occurred for client
Could't find a proper solution anywhere. Pls suggest...

Need more info than that... can you post your show wlan <wlan id>
Make sure that if your using WPA, that you only either use WPA/TKIP or WPA2/AES, not both or a mix of one or the other.

My wifi is not connecting but searching the device

Please tell what to do , my wifi is not connecting to device but already searched the device

Some things to try first:
1. Turn Off your iPad. Then turn Off (disconnect power cord for 30 seconds or longer) the wireless router & then back On. Now boot your iPad. Hopefully it will see the WiFi.
2. Go to Settings>Wi-Fi and turn Off. Then while at Settings>Wi-Fi, turn back On and chose a Network.
3. Change the channel on your wireless router (Auto or Channel 6 is best). Instructions at http://macintoshhowto.com/advanced/how-to-get-a-good-range-on-your-wireless-netw ork.html
4. Go into your router security settings and change from WEP to WPA with AES.
5. Renew IP Address: (especially if you are droping internet connection)
    •    Launch Settings app
    •    Tap on Wi-Fi
    •    Tap on the blue arrow of the Wi-Fi network that you connect to from the list
    •    In the window that opens, tap on the Renew Lease button

I recently updated my apple tv and now you wifi will not connect all other devices in the room are connected to wifi

Go to your ipod touch wireless settings chose your network and right beside there is button looks like ">" click on that check the dhcp what IP are you getting? do you get any ip? if you do your ipod touch should work with wireless no problem. Also, you may have to enter wep key again. After that it shou,d save your device

Bought a new Ipod touch and the WiFi does not connect. Tried Reset and total Restore, does not connect to Router on DHCP, tried Static manually and still can not get it to connect even though it registers as connected.

Bought a new Ipod touch and the WiFi does not connect. Tried Reset and total Restore, does not connect to Router on DHCP, tried Static IP, Subnet, Router and DNS manually and still can not get it to connect even though it registers as connected. Using Airport for router, latest firmware, no problems with Iphone 4 or Macbook Pro or any other internet devices. After total Restore (factory settings) tried again, showed connected to router, but does not display "check" next to router but little rotating icon even though the wifi range signal shows connected at full strength and it says it is connected. Just can't seem to get it to generate an IP. Any solutions other than turning it on and off again? Not a Merry Christmas morning.

Ok, so, a couple of things: Denisefromwaleska and I have the exact same size/type/color iPod. Now wishing I'd bought the black one maybe...
Second, Airport is an Express and I have a second one that I carry with me when I travel. Tried to connect my Airport Express to the internet and could not although the iPod did recognize the router and tried to connect to the internet for some time, unlike my previous problem. Updated firmware on my travel router, still could not connect to the internet. Going to try to set up a manual Static IP on the travel router here in a few and conect through it although I predict the problem will persist. Back on the Christmas Present Airport Express router, it is back in play and working fine for all devices save the iPod.
Thanks again for all your help, hopefully I can get a solution in place soon,

Disabled
Place the iOS device in Recovery Mode and then connect to your computer and restore via iTunes. The iPod will be erased.
iOS: Wrong passcode results in red disabled screen
If recovery mode does not work try DFU mode.
How to put iPod touch / iPhone into DFU mode « Karthik's scribblings
For how to restore:
iTunes: Restoring iOS software
To restore from backup see:
iOS: Back up and restore your iOS device with iCloud or iTunes
If you restore from iCloud backup the apps will be automatically downloaded. If you restore from iTunes backup the apps and music have to be in the iTunes library since synced media like apps and music are not included in the backup of the iOS device that iTunes makes.
You can redownload most iTunes purchases by:
Downloading past purchases from the App Store, iBookstore, and iTunes Store
If problem what happens or does not happen and when in the instructions? When you successfully get the iPod in recovery mode and connect to computer iTunes should say it found an iPod in recovery mode.

How do i restore my wifi setting back to the factory settings? I have changed it somehow :/ and now my wifi will not connect. My Airport is on and showing full strength but will not connect.

Ok, if other devices are connecting but just not your MacBook then let's start troubleshooting the MacBook to possibly find out why.
Please try each of the following, in order, until hopefully resolved:
Note the following are excerpts from an OS X Daily article.
* Turn Airport on & off – You can do this via the Airport menu bar or from the Network Preferences. This is the first thing you should try when troubleshooting Mac wireless problems.
* Make sure Wireless/Airport card software & firmware is up to date – This is usually done just by going to the Software Update menu, if there are any updates available for your Mac or Airport, install them.
* Delete and recreate connection – Try deleting and recreating/reestablishing the wireless connection, sometimes a setting can be corrupted and this may fix it.
* Create a new Network Location – Similar to the above suggestion, try creating a new and different wireless network location to see if it resolves the connection problems.
* Change DHCP auto settings to manual – sometimes there is a problem with the DHCP server, and if you manually set an IP address on the network you can be fine. Remember to set the IP to a high number so it wouldn’t interfere with other DHCP machines. As long as you have the subnet mask, router, and DNS settings configured manually as well, this shouldn’t be a problem.
* Flush the DNS cache – Launch the Terminal and enter the following command onto one full line within the Terminal: dscacheutil -flushcache
* Zap the PRAM – Reboot your Mac and hold Command+Option+P+R during restart until you hear another chime, let the Mac boot as usual.
* Delete Wireless Config files – Delete com.apple.internetconfigpriv.plist and com.apple.internetconfig.plist files from ~/Library/Preferences and reboot
* Trash your home directories SystemConfiguration – Remove all files within ~/Library/Preferences/SystemConfiguration/ and then reboot your Mac.
* Reset your Mac’s System Management Controller (SMC) – For MacBook and MacBook Pro’s: Shutdown the MacBook/Pro, remove the battery, disconnect the power, hold the Power Key for 15 seconds. Replace the battery, reconnect power, and zap the PRAM and wait for 2 chimes before letting the keys go. Let boot as usual.

Same here.... No fix. Replacing is the option apparently and if you're out of warranty, you're SOL. That was as per the "Genius" at Apple.

MuVo "device not connected" firmware update error

When I try to execute the plan given by Pook Kok Choy (below between "=====")
I successfully get MUVO_DRV_LB_00_04_250.exe installed.
When I move to step 2 I have the device attached to the PC but I get the message "device not connected to the USB port".
This happens, with the device connected and on while trying to install:
MUVOAudible_PCFW__40_2_L4.exe
Apparently, I am not alone in having this problem.
Apparently, this happens to others - using XP - specifically when trying to do this firmware upgrade in order to play purchased WMA, DRM protected music.
The PC recognizes the MuVo 28.
It assigns it a dri've letter when it is plugged in.
The install procedure for the *Audible* firmware does not see it.
Please help.
Tbanks,

JLRtist,
After you have installed the latest downloaded driver, did you run the player into recovery mode? Try this,press and hold the PLAY button, continue holding the button while inserting the player into the USB port for about 0-5 sec. Run the firmware update file.

WLAN override option not available for WLC 4402 - 6.0.196.

Hi All,
Its kind of weird BUT it seems that the option for WLAN override is missing.u.
I could find it on the lower version BUT not on the 6.0.196.
Please help.
Does this mean I could only set it up via the WCS and not the WLC directly.
Thank you.
Warmest Regards,
Azzafir Ariff Patel.

Hi Scott,
Thank you so much for the clarification.
Thanks again.

I replaced an old airport extreme with a new one. None of my wifi devices will connect - always say incorrect password. Reinstalled old device, works fine. Any ideas?

I have a 5 year old airport extreme. I bought a new one to upgrade for better range. I connected the new one to the internet with a few problems, but a phone call to my internet provider resolved them. With an ethernet cable from the new airport extreme to my iMac, I'm connected. However, none of my wifi devices will connect. They see the network, but it either says "incorrect password" if I'm trying a new network name and password, or it repeatedly asks me to reenter the password if I use the old ones. I reinstalled my old airport extreme and everything works fine. I'm about ready to box up the new one and return it. Any ideas?

It is extremely difficult to fix these issues.. remotely.
If none of your wifi devices work.. that does sound unusual..
Have another try.. This time deal with the COMPUTER only.. leave everything else turned off.
Unplug the Extreme from the router.. reset it to factory.. do this full setup.
Unplug power from the Extreme.. hold in the reset button.. plug in the extreme to power and keep holding in the reset.. 10sec or so the front led should flash rapidly.. release the reset and wait a couple of min.
Now in the computer does the Airport extreme show up under wifi as new device??
Please make sure IPv6 is set to link local only to go further but it should work no matter what the settings are.
No luck clear out all the old wireless names from the computer.. reboot the computer and try again to scan for new wireless devices.
Hold the reset and try again.. it must appear in the wifi to be setup.
No sign of it the unit is faulty and can be returned.

Hi glomp,
From the information provided, it sounds like your device may not be fully recognized by iTunes. Here are two articles (depending on your computer's operating system) for troubleshooting this:

Hello, give this a try...
Make a New Location, Using network locations in Mac OS X ...
http://support.apple.com/kb/HT2712
10.5, 10.6, 10.7 & 10.8…
System Preferences>Network, top of window>Locations>Edit Locations, little plus icon, give it a name.
10.5.x/10.6.x/10.7.x/10.8.x instructions...
System Preferences>Network, click on the little gear at the bottom next to the + & - icons, (unlock lock first if locked), choose Set Service Order.
The interface that connects to the Internet should be dragged to the top of the list.
For 10.5/10.6/10.7/10.8, System Preferences>Network, unlock the lock if need be, highlight the Interface you use to connect to Internet, click on the advanced button, click on the DNS tab, click on the little plus icon, then add these numbers...
208.67.222.222
208.67.220.220
(There may be better or faster DNS numbers in your area, but these should be a good test).
Click OK.
