Motorolla RF scanners getting disconnect and connecting back

Hi i have deployed wlc 5508 with software 6.0.199.4 . AP 1142 . Customer have few motorola RF scanners which i added the mac address
in mac filter and its working. Now cust informed that these scanners get sometime diconected in between and connects back .
and its using telnet application .
Can anybody help me out do we need to do any other configuration in WLC .

Just to add.... have you done a post site survey to verify coverage? Since its scanners you mentioned, I'm guessing it might be in a warehouse environment. Well how high are your ap's placed and what power level is RRM setting your TX power. You might have to tweak that so that the TX power doesn't drop too low. On the WLC, the lower the number the more power (1-8, 8 being the lowest power). Take a loot at the power levels and if you see 4-8, then I would maybe set the max and min power levels for both the 2.4ghz and the 5ghz. Or else you can manually set the TX power level on each AP:
Depending on how old these scanners are, make sure your data rates are at default with 1 & 2 mbps set to mandatory. You can also issue a debug client and post the output when the client is having issues and also post the client monitor detail when the issue is happening.

How do I get the internet connection back onto ipad even though it connects to Wifi successfully and I have checked on my iPhone which does connect via the same wifi and to the internet?

Your router may not have given your iPod a valid IP address. Go to Settings > Wifi > your network name and touch the ">" to the right to see the network details. If the IP address shown starts with 169 or is blank then your router didn't provide an IP address and you won't be able to access the Internet.
Sometimes the fix can be as simple as restarting your router (remove power for 30 seconds and restart). Next, reset network settings on your iPod (Settings > General > Reset > Reset network settings) and then attempt to connect. In other cases it might be necessary to update the router's firmware with the latest from the manufacturer's support web pages.
If you need more help please give more details on your network, i.e., your router make/model, the wifi security being used (WEP, WPA, WPA2), etc.

My wifi was disconnected and turned back on. Now my phone either won't connect to the wifi or connects but doesn't work

Reset network settings.

Then re-connect to WifI by setting it up again.

IChat disconnects and connects many times

when i'm connected via ADSL, my connection to friends thru iChat keeps disconnecting and connecting over and over again. is it my connection speed? i'm able to surf the web,etc fine, but iChat or Skype goes in and out of connection.. help please.thanx

This does depend on the actual spped of your IChat connections as well but:
Min connection speed is 100 Kilobits per sec
A min is therefore 6000 Kilobits and so on.
Add to this any other download and reugular web browsing, mail Send and collection (particualrly if they contain Pics or files)
Don't forget the just having iChat open and Logged in is constantly sending data back and forth regarding keeping the Buddy list updated with new Buddies, their icons (And changes they make) and their online status, not to mention changes in the Audio or Video Status.

I have pluged a portable battery to the USB and my macbook pro stopped working after that, right before it shut down there was a message on the screen that said something like " USB device is withdrawing so much power, please disconnect and connect again?

I have plugged a portable battery to the USB and my macbook pro stopped working after that, right before it shut down there was a message on the screen that said something like " USB device is withdrawing so much power, please disconnect and connect again?
if the device I connected have caused this, shouldn't the macbook itself have some type of protection that should prevent this from happening.
because when I took it to an apple certified maintenance shop, the guy said that now it could only run while connected to the power. it won't run on batteries. and that I have to change the motherboard.
can I just replace the damaged part only, would apple consider this as a design issue and they could pay for it, or should I just buy a new motherboard for 800$.
Help.

BB1B2,
The problem is in finding a tech shop that will/can do board level repairs on Macs. They are few. And I certainly wouldn't spend $800 on a new logic board - I would replace the computer if I had to pay that much!
You could call around to a few repair shops and see if they feel competent to isolate the problem and do a board level repair - but I'm afraid, in the end, that your search will be futile.
Sorry,
Clinton

Since installing 4.0.1 I can't right click on the Icon in my task bar and have Firefox give me the option of "close and save" the tabs. Only let's me know I'm about to close multiple tabs. How do I get "save and close" back?

Before installing 4.0.1 I could right click on the Firefox icon on my computer's taskbar and hit close window. It would then give me the option to "save tabs and quit" or "close all tabs."
Now it just alerts me that I'll be closing multiple tabs.
It was convenient to be able to close Firefox and open it with all of the tabs in place. There is nothing more irritating than having multiple tabs lost because your computer did an update overnight and restarted. Also it was helpful when you wanted to run a tun-up or cleaner that asked you close out of your browser for optimum result's.
How do I get "save and quit" back?
Thanks

Firefox now always stores the old session, and you can access it by going to the History menu and selecting "Restore Previous Session"
If you want Firefox to display the message to save the session, it can be turned back on by changing some preferences.
# Type '''about:config''' into the location bar and press enter
# Accept the warning message that appears, you will be taken to a list of preferences
# Locate the preference '''browser.tabs.warnOnClose''', if its value is set to '''false''', double-click on it to change its value to '''true'''
# Repeat this for these 3 preferences '''browser.warnOnQuit''', '''browser.warnOnRestart''' and '''browser.showQuitWarning'''
If you always open the last set of tabs, an alternative approach is this:
# Click the orange Firefox button, then select options to open the options window
# Go to the General panel
# Change the setting "When Firefox starts" to "Show my windows and tabs from last time"

Iphone 4 disconnecting and connecting repeatedly while playing music on PC

No one? I have a hp dv7-3085dx if that helps...Please help. People at the apple store didn't even try to help me when I asked...

Time Capsule 2TB was working until i disconnected and connected again.

Now the airport utility says "no configured AirPort base stations have been found."
And it has a flashing orange light.
I moved it from the house to another apartment.
I want to get back whats inside of the Time capsule, and back up again.
PLEASE HELP!

OK, newer laptops do not have an Ethernet port, unfortunately.
But i am conected to wi-fi on this device (computer) and my iphone.
Is this the Time Capsule WiFi signal, or does the complex provide a WiFi signal?
So internet is working.
So, you can connect to the Time Capsule WiFi and get an Internet connection on your laptop and the iPhone?
Or, does this mean that you are connected to another WiFi network (not the Time Capsule) and you have an Internet connection?

TS3221 My Iphone 5 disconnects and connects automatically repeatedly on windows 8.

I uninstalled the itunes and downloaded the latest version but I still have the same issue.

thank you

Hello Kelly1gh,
It sounds like you are plugging in your phone to your computer, and it keeps acting like it is being plugged in and unplugged over and over. I recommend troubleshooting the USB on the computer with this article:
iOS: Troubleshooting USB-related alerts when syncing
http://support.apple.com/kb/TS5254?viewlocale=en_US
See if the cable connection at the device or computer has come loose or unplugged.
Unplug the cable you're using to connect your iOS device from the USB port on your computer, and then reconnect it. Then unplug it from your iOS device, and reconnect it.
Remove any third-party battery packs or cases from the device and ensure that the USB cable is connected directly to the port on the device.
If your Lightning or 30-pin cable is connected to a keyboard, display or USB hub, try plugging it directly into a USB port on the computer instead.
Close any virtualization apps (such as Parallels or VMWare).
These apps may interfere with your computer's ability to communicate over USB if they aren't properly configured, or up to date. If this resolves the issue, contact the developer of the app to see if an update is available.
Restart your computer.
Restart your iPad, iPhone, or iPod touch.
If you're using an accessory or third-party cable to connect your device, try using an Apple cable with the device instead.
Update to the latest version of iTunes if you have not already.
Disconnect other USB devices from your computer, except for your keyboard and mouse. Then, reconnect your iOS device. If the issue is resolved, reconnect the other USB devices one at a time. Make sure your iOS device is still recognized by the computer after adding back each device.
If one of these steps resolves the issue, but it comes back later, make sure you haven't changed how the device is connected. For example, check to see if you plugged the device into a specific accessory, or used a specific cable that reintroduced the issue.
Thank you for using Apple Support Communities.

Getting songs and videos back I've already purchased

I have the 2nd generation iPod touch. I just upgraded my old software 3.1.1 to the new 4.1 software. It took about 5 hours to back up my iPod do all this other stuff. Apparently it restored it to factory settings so I lost all my videos and songs. I can get most or my songs and videos back but, what if I bought them with my iPod and didn't transfer the purchases to my computer? Where can I go to recover those? Because that's a lot of money I spent. Please help me and give me any suggestions that could maybe help me. I'm really stuck right now.

so i updated my ipod and it took 3 hrs and this morning i see it didnt save any of my songs i recently purchased and songs i had for years. wat can i do to get them all back?

thanks all

the following post by Zevoneer in this thread http://discussions.apple.com/message.jspa?messageID=8794716 says it all:
Did you back up your purchases before you you reinstalled your system? If you erased your drive then the purchases will have been erased along with everything else. If you didn't make a back-up of your purchases to restore from (as you are advised to do) then I'm sorry to say that the policy on lost purchases is that you have to pay to download them again:
"Once a Product is purchased and you receive the Product, it is your responsibility not to lose, destroy, or damage the Product, and Apple shall be without liability to you in the event of any loss, destruction, or damage." iTunes Store: Purchased content can be downloaded only once
You could try contacting the iTunes Music Store Customer Service and you might be able to persuade them to sanction a second free download. There have been occasional reports in the iTunes forum of this happening, however just be aware that they are not under any obligation to do so. If you click on this link you'll be able to email your query: iTMS Customer Service
If you have an iPod that still has the purchases on it the transfer of purchased content from the iPod to authorised computers was introduced with iTunes 7. You'll find details in this article: Copying iTunes Store purchases from your iPod or iPhone to a computer

Outlook Keeps disconnecting and connecting right away using ZenLoadBlancer

Hi Guys,
Have you seen this before? Im not sure you are familiar with this load balancer but if you are can you help me with the configuration? Everything is working fine except outlook a few times an hour disconnects and reconnects right away. I heard
it might have to do with my load balancer and time-out settings. Any help would be greatly appreciated.
Thanks

Hi,
Firstly, I’d like to explain, the connection issue may have many reasons and is not limited to the load balancer configuration.
Thus, to narrow down the cause, I’d like to confirm the following information:
Does the issue happens on all users including external users and internal users?
Does the issue happen randomly or regularly?
Does the problematic Outlook user use online mode or cached mode?
Can the issue be reproduced if you make client pass the load balancer and directly connect to CAS server?
If you have any question, please feel free to let me know.
Best regards,
Angela Shi
