Connectivity problem after adding a second WLC

I have a client with two identically configured WLC's running 7.0.230.0 with approximately 370 AP's. We are currently testing before going into production and found that once the 2nd WLC comes online (same mobility/RF group), the clients are no longer able to connect / obtain an IP address. We removed all security and still had the same issue when the 2nd controller came online. This sounds like a bug and I'm thinking about upgrading to 7.2x, however, that requires upgrading the MSE/NCM. Although I don't mind doing this upgrade, I was just wondering if anyone else has ran into this issue.
I did run both configuration files through the WLC Config Analyzer and nothing seems to jump out other than some typical RF issues.
Thanks,
Bob

Simon,
No IP Conflicts. Ironically, when we broke the Mobility Group, everything is working fine and clients are able to obtain their IP addresses from the DHCP servers.

Airport extreme connection problem after adding computer to network

just added new imac to my network and for some reason my older imac {dome desktop} seems to have stopped recognizing the AEBS. the older imac was hooked up to the AEBS by ethernet and when i moved it across the room it fails to read the AEBS. I had installed the airport card a few mos ago and i know it worked...although most recently was ethernet connected. I cannot be certain the new computer addition is even related but seems to be. Have checked all the airport utility settings and see no issues. I did fool around with some network sharing features on the imacs so ? if that can create issue sharing the AEBS. Interestingly the affected imac does detect the AEBS in the utility app but times out when attempting to connect. also think i may have done recent AEBS download upgrade and see threads related to that as poss issue . have reverted back to older AEBS software without success. new ibook and new imac detect/connect without problem. Any thoughts out there??? thx for any help.

Is your AEBS configured to create an 802.11g compatible network? It must be for the iMac G4 to connect.
What channel is the AEBS configured to use?
If the AirPort Extreme card in your iMac G4 is from the US it can only use the channels between 1 and 11. If your AEBS is from somewhere else in the world it can use other channels which are not available for use with equipment from the US.
If your AEBS is not using a channel between 1 and 11, change it and see if your iMac G4 can connect.

Timeouts and connection problems after 5.1(2) upgrade

AIM/chat and some other programs are having timeout/connection problems after upgrade to 5.1(2). I am using S241 also. The connection problems stopped when the IPS was set to bypass. Rebuilt IPS and left sigs at default settings and problem is still happening. I am not seeing any of the IPs that are having the problem in the Event Viewer or on the Events in the IDM.
Any known issues with the 5.1(2) that would cause this type of problem?

I don't know specifically, but I did notice that 5.1(3) was released today.

XE connection problem after using Cisco AnyConnect Client

Hello
I have a rather annoying problem connecting to an XE instance AFTER I have disconnected from a VPN via a Cisco AnyConnect VPN Agent.
Sequence of operations:
- start Oracle XE and work normally
- connect to client's vpn
- do other stuff
- DISCONNECT from Client's VPN
-> unable to connect to XE service any more, unless I reboot
The problem does not happen with other vpn clients like Cisco VPN Service, Juniper, Checkpoint.
Details:
- sqlplus connection WITH service name (eg sqlplus user/pwd@XE): FAILURE with ORA-12170
- but...sqlplus connection WITHOUT service name (eg sqlplus user/pwd): SUCCESS (weird !)
- tnsping XE: TNS-12535 error

Dial-up connect problem after 10.4.9 update

After installing the 10.4.9 update it has been very difficult to connect to the dial-up internet server. It may take 19 tries clicking "Connect" before it connects and sometimes it connects after four tries. The error messages vary: unable to connect to PPP or no carrier detected are the most frequent messages. Once on-line everything works fine except for being able to send mail. I'm unable to send mail - that error message wants the SMTP server settings and any advanced settings checked.
I called Apple support and the Apple Tech had me reconfigure the Network to dial an "800" number to a PPP Dial-Up Test Site. When that worked succussfully a window displayed a message that the modem, the PPP or Remote Access software, the TCP/IP software is functioning and correctly configured for a PPP connection to this server. The Apple Tech checked the information on the 10.4.9 upgrade and did not find any reason to think it would cause this problem. Apple Tech suggested I contact the dial-up server.
The dial-up server went over all the configurations and they were all correct. During my phone call to them they could hear the computer dial-up sounds and said it sounded like the normal "hand-shake". The dial-up server has had no reports of problems with connecting to their service other than mine.
If anyone knows what could have caused this problem, how to fix it or has the same problem I'd be very interested in hearing from them.
Thanks, AppleProblem

You have been most helpful and we think the problem is solved. After I send this message explaining what has transpired I'll go back and click on the "Solved" button.
Based upon your suggestion to try "Script, like v32" I started experimenting with the four internal modem options we have in our Modem settings. They are v.32, v.34, v.90 and v.92. I tried to connect three different times with each one. The v.32 didn't connect, the v.34 connected all three times, the v.90 connected the first two but not the third or the fourth try. On the fifth attempt the Mac froze up, the mouse/arrow wouldn't work and there was a high speed motor sound. I tried a Force Quit (Option,Command,Escape), I tried a Hard Shut Down (holding the power key) and when these didn't work I pulled the plug. Then, I booted back up and connected on the second try using the v.90. I don't know why the computer froze up and assume it is nothing to be concerned about.
I then called our ISP and found that the two access numbers are both v.90. I suspect that until we did the version upgrade to the 10.4.9 that our computer was accommodating the v.90 eventhough it was a v.92 (!?!). Just a guess.
I also asked the ISP tech why we couldn't send mail. He asked if we had the password set for the outgoing mail. He said if we're using the access number owned by them it didn't require a password but the other access number is not owned by them and is used by other ISPs and it does require a password. We had never set up our Mail Preferences outgoing mail settings to use a password. Before our connect problems we had always used the number owned by them and after the connect problems we started using the other number because we found that we could connect to it with fewer attempts. We put in the necessary information and now have no problem sending mail.
We have also been looking for another ISP and the web site you gave us www.fastermac.net looks very promising. They have one access number in our area and we want to check if it is v.92 or v.90. During our research for an ISP we learned that if it is a v.92 access number (and we use our v.92 modem) we'll be able to answer phone calls and remain online. That will be a real blessing. Thanks!
We really appreciated your brain storming with us and your perseverance. Thanks so much!

Bluetooth Connection lost after a few seconds - EV...

Hey,
I have an new Nokua Lumia 920. I want to connect my Lumia via Bluetooth to my laptop and in the university I treif to connect it to another laptop, as well as to my old XDA Touch Diamon!
The problem: I can find all bluetooth devices and can also connect to them, BUT every connection is lost after about 5 seconds. This cannot be! Here are my firmware versions - are there issues?
OS-version: 8.0.10211.204
firmware-revision-version: 1232.5957.1308.0007
hardware-revision-version: 1.0.0.0
radio-software-version: 1.0.202093.3
chip-SOC-Version: 8960
I am located in germany. Anyone has a hint or solution - phone nearly useless to me without bluetooth.
Best regards

You do not have to be bluetooth connected to transfer files to and from the phone.
Initiate the trandfer and it will happen. If they have been paired before, no passcode will be required.
Theey won't keep a BT connection because none of the profiles the phone has requires one.

WiFi Internet connectivity problems after upgrade to 10.8.4

After upgrading to MacOS 10.8.4 I am facing regular interruptions to my WiFi internet connectivity. Periodically the internet connectivity is lost and the only way to fix the problem is to turn WiFi off and on again. This happens frequently when I am downloading files at using big bandwidth (more than 1.5-2 MB/s). If I use assist me on the Network preferences tab, it displays an ISP error when the connectivity is down, however I am certain that I do nota have any kind of ISP or router issue since at the same time I have WiFi internet connectivity from my iPad mini, iPhone 4S and Samsung Galaxy S3. Therefore it should be a 10.8.4 issue

How to change security questions after adding a second email address?

I'm at a loss and really really frustrated with Apple for the first time in my life.
I've added a second email address and tried over the last 3 days on my iPad and Mac to change my security questions. There is no option present that I can see that allows you to do this without first entering the answers. (to which I don't know anymore)
I called Apple support (even in english) and every time the call has been dropped.
In all the years since switching to Apple I've always been impressed with the level of customer service. This is the first time that I've felt this level of sincere frustration.
I'm not sure why I have to book a time to speak with someone. Updating or changing security questions, should be a process one can do over the internet. I'm confused either way why questions are necessary if the apple password entered was correct. It's not my bank account; why the need for such extreme security just to download an app paid for by an iTunes card!
Any help or direction would be appreciated!!
Thank you
Kate

Hello there, Kate.
Apologies for your frustration. For your security the existing questions need to be answered before new ones can be created. The following Knowledge Base article provides some additional steps to try if you are unsure of the answers to the existing ones:
Apple ID: All about Apple ID security questions
http://support.apple.com/kb/HT5665
Specifically:
What should I do if I don't remember the answers to my Apple ID security questions?
Try answering them at least once to see if you can get them right, even if you are not sure you remember the answers to your security questions.
If you are confident you can't remember them, try one of the following:
If you have three security questions and a rescue email address
sign in to My Apple ID and select the Password and Security tab to send an email to your rescue email address to reset your security questions and answers.
If you have one security question and you know your Apple ID passwordsign in to My Apple ID and select the Password and Security tab to reset your security question.
If you have one security question, but don't remember your Apple ID password
contact Apple Support for assistance. Learn more about creating a temporary support PIN to help Apple confirm your identity when you contact Apple Support.
Note: If you have forgotten your password and answer your security questions incorrectly too many times in a row, you will be unable to try to answer your security questions for a period of time. During that time you will not be able to reset your password and will not have access to your account.
Thanks for reaching out to Apple Support Communities.
Cheers,
Pedro D.

Connection problem after firmware update 7.5.2

Until I update 7.5.2, my Airport Extreme station worked fine. But now every time my computer starts it fails to connect to the station. I have to recreate à new connection on my MBP or I have to disable and enable Airport repeatedly to establish a connection. (No connecting problems with my Iphone, but same problem with another MBP).
Need some help, thanks

The question of which channel to use is very dependent upon your environment. Probably the #1 item to work through is finding a channel that is relatively free of other interference. This is especially true of the 2.4 GHz band (802.11 b/g) which has been used for quite a few applications. This includes:
- Other WiFi base Stations
- Bluetooth devices
- Microwave Ovens
- Some Cordless phones.
In the case of Cordless Phones and other Base stations, these can often be from your neighbors, so you may have to use trial and error to find a channel.
In my particular case, all of the devices which were failing were trying to use the 2.4 GHz band on 802.11 b/g. When it was set to "Automatic" the Base Station software indicated that my base station was using Channel 1. I just set it to Manual and selected Channel 3 and things started working for me. (Since it required me to make a selection for the 5 GHz band, I whose Channel 48 for that)
The key in any situation is to find one not in use by other devices. Normally, selection of "Automatic" allows the Base station to make this choice by listening when it is not broadcasting and trying to sense other items on the same channel. However, this doesn't always work 100% because your end device (like your PC) may be closer to the other source of interference and it can "hear" transmissions that the base station cannot.
What I find strange is that this inability to select a free channel appears to have been triggered by the firmware upgrade, so perhaps there is something in this new firmware which doesn't do as good of a job of finding the clear channel to use.
I hope this helps someone else out there as well!

Mail Connection Problems after latest Maverick Update

My macbook pro contains the latest OS Maverick update (12/17/2013) and I am still having mail connection problems.
Several times an hour the mail app is dropping the mail connection on all my accounts. I have to sign in to all my connections each time the connection drops. Does anyone think of a solution to this problem? Anyone else still having this problem with Maverick Mail connections?
Thanks

Same problem here. For a couple of weeks, I've had an error message that my accounts can't log in. I've gone thru the account prefs and made sure all settings are correct and set to Apple's suggested settings. Also getting double messages sometimes. Not all messages, but one or two will be doubled. This happens on my iPhone and Mac's. If I scroll the window the double message disappears.
Also had lots of errors that mail can;t be deleted. I go back and delete the message again and it goes away.
I kinda feel like this is Mavericks related since these issues were not happening under ML.

Problem with adding a second Categories field to my Enterprise Wiki Page template

I wanted to add a second category field beside the default wiki category. So I did the following steps:-
Inside my enterprise wiki site collection, I added a new Site Column, named “customer” with a managed metadata type.
Then I added the site column to the “Enterprise Wiki Page” content type.
After that using the SharePoint Designer , I added the new “Customer ” column to my EnterpriseWiki.aspx page layout.
The result was that I got a new category field , but I am facing these two problems:-
When selecting items for the new metadata column, the items are not clickable, unlike the default Wiki Category field, which allow users to click on the terms , as follow:-
The new category column was not displayed inside the Tree View , same as for the default Wiki category, as follow:-
So can anyone advice how I can solve these two problems ? Thanks

The Visio Web Part displays Visio diagrams that are located in SharePoint. Once you log out it won't have access to your desktop anymore. Instead you should upload the Visio document to a SharePoint library and then reference it from
there. It would be nice if it was integrated into a single process, but I suspect its not something MS thought enough people would do to spend the time writing the extra code to integrate it. So at least for now its a two step process.

Connection problems after 10.7.5 update

After updating my mid-2010 MacBookPro from 10.7.4 to 10.7.5 my network connectivity is severely compromised.
What happens is that I can't get an external IP from the modem/router.
This occurs at home (where other devices are able to connect properly) and at work,
does not occur whet booting Wind*ws 7 through Bootcamp (only tried at work so far),
and both through ethernet and wifi.
I blame the DHCP and I think the problem is that my mac is not able to get proper settings for 'subnet mask'.
When set manually at home to values that I know they work, and after rebooting the mac and the modem/router 3-4 times (and some voodoo magic)
I got lucky yesterday, only to see the problem coming back today.
Anyone gets the same/ has any suggestions?
I reinstalled from 'client combo' but still the same.
My second to last option seems to restore 10.7.4 from TimeMachine.
My last to update to 10.8.2.
Thanks,
Vassilis

It appears that this is not an uncommon problem:
