Cisco WLC 2504 internal DHCP does not work properly
I m trials with a Cisco WLC 2504 and some APs of 1832. I set up a DHCP scope on the interface of the controller with 2
a large number of different configurations, but the DHCP protocol does not work and Don t Access Point to obtain an IP address. My first question: is it possible to do DHCP for Access Points or only for wireless clients?
These are my interfaces:
Interface of the PA-Manager:
My DHCP scope:
I forgot something? Is there anyone using DHCP for its access points?
On Cisco WLC internal DHCP, you can add the option 43 to say where APs must register. In this case, they will try to resolve the DNS CISCO-CAPWAP-CONTROLLER or CISCO-LWAPP entry.
Let me explain briefly how AP-Manager works on WLC:
- Boots of Access Point and sends a discovery request to the management interface of the controller using the intellectual property you configured as DHCP Option 43 (as described above, it can be resolved by the DNS entry)
- Controller, sends it a response discovered that contains the name of the system, addresses AP-Manager, the number of access points already connected to each interface AP-Manager and the overall capacity of the controller.
- Joints access point controller using the less loaded interface AP Manager.
With this, every AP Manager must have a good configured interface and be connected to a different port, no LAG.

I'm completely stuck I have a portable satellite c660 keyboard did not work.
So I bought a replacement keyboard and installed and checked in the Device Manager and it says it is there and works correctly, but the replacement keyboard still does not work.
I updated the bios and uninstalled the keyboard drivers and reinstalled them that I've done everything I can think off to try and get this new keyboard working but I am having no luck and could so with some assistance.
Have you ever checked if the USN external keyboard works properly?
I ask because in the case where the external keyboard does not work properly, the internal keyboard problem could be related to faulty keyboard controller (motherboard) or a problem of system m.
In case the external keyboard would work properly, you had any luck with the new keyboard. It might be possible that the new keyboard is malfunctioning.
I have a Toshiba L500-1PU, running on 32 bit Windows 7,

Try reinstalling the Audio driver from the support site.
Click Start, Control Panel, audio recording tab. What is mic/line to IDT High Definition Audio Codec selected as default device?
Let us know how it goes.
I tried to understand why my internal microphone does not work for me.
What operating system do you use?
Did you of recent changes made to your PC before that?
Often, sometimes with a question like that, there is a problem with the driver. If you recently updated your PC, that might be the problem.

Reinstall the driver and check with the question.
a. click Start, type devmgmt.msc in the start search box and press enter
b. right-click on the device and click on uninstall. Restart the computer and allow the driver to install.
You can also consult the site mentioned below.
I searched on the web, without success, to find how to solve this problem.
I recently installed Windows 7, 32 bit, on laptop HP Pavilion dv6748us to my wife. Now its internal microphone does not work.
Have got some advice "roadside" use a Windows Vista driver; Have no idea what is the driver or how to get it.
Have found information about uninstalling driver realtek audio and reinstall an earlier version; Have no idea about it no more.
Would appreciate an answer with a positive result.
Thanks for any help.
Looking at your system information, you may have one of two possible audio cards:
Conexant HD audio or the RealTek HD Audio
The fact that you could not install the RealTek HD audio driver tells me that you don't have a sound card RealTek. Check your device manager and look at your sound card and check what sound card you have.
Here are the Vista 32 bit driver for the Conexant sound card:
Here are the Vista 32 bit driver for the Realtek sound card:
If you have the Realtek audio card, I would download and install the driver of more recent, HD directly from RealTek site:
Accept the agreement, download and install one on the list. Maybe it has been updated to solve the problem you are experiencing.
Difficulty of DVD player or buy the external drive
My DVD player does not work properly, in fact it can never work properly. Recently, I tried to back up my PC on a DVD using Norton 360. Norton did not recognize that the DVD was present. Then I tried to write a text file on a DVD and was a failure. DVD + R and DVD-R media were found to be (Maxwell 16 X).
I could have probably lived with this however, I received a copy of Dragon NaturallySpeaking version 10 on a CD and my Toshiba would not recognize it. I tried the CD in my laptop nearby and it was recognized.
An attempt to update the driver has also fails.
I was able to copy a CD of music last night so that at least works properly.
Does anyone know how can I fix? The important part is to be able to load my new program.
Research on some forums I found that other people have had problems with the Pioneer drive. If the drive can't be fixed, I'm not adverse to buying an external DVD drive. Unfortunately, where I live there is no brick and mortar stores selling external drives and I prefer to avoid the hassle of getting a drive online and discovering that it does not work with my Toshiba. Can someone suggest an external USB drive that will read and write CD and DVD and is certain to be compatible with my Toshiba?
Thanks for any help,

Any external USB CD/DVD drive will be compatible with your laptop.
However, you won't be able to boot from CD (run recovery for example) If you are using an external drive.
So, your best option would be to replace the internal drive with a Toshiba drive designed for the laptop. Call an ASP and request a quote.
My Apple TV remote 3rd generation A1294 aluminium does not work properly, battery is good, and I tried all the resets including factory reset. the battery compartment is clean.
You don't say what you mean by not working not properly, however...
Your Apple TV can become affiliated with another remote control. Hold the remote control close to and pointed on the Apple TV, press and hold the menu and rewind buttons together for 6 seconds or until you see an icon of the chain broken on screen.
I downloaded Multi Access Tool from Mcafee with Firefox Mozilla, how do I reinstall if it does not work properly?
My sincere apologies, my Mcafee came via the Optimum/Cablevision, not Mozilla. I now managed to solve my problem and appreciate the 2 above responses. Thank you.
hope that this issue has not been covered before, but I've owned a Satellite P200 for 3 years now, and this week, it crashes all the time.
When it started going down he gave me a few messages in the sense of "your graphics card/driver does not work properly and windows will be arrested to avoid damage.
It has progressed to the point where now when I turn it on, I have vertical lines running down the screen and the screen flashes on and outside. Within 20 seconds, it restores the BSOD - 'there was a problem and windows will be arrested. Error Page_Fault_In_Non_Paged_Area"then stops.
I ran a system restore but the problem remains.
I have a feeling that my graphics card is toast. Is this good? Are there any other options to try? Thanks in advance for any answers.
Sounds like the GPU problem.
But try the graphics card driver update.
Use the most recent driver for your graphics card.
In addition, clean the fans of portable computers.
Dust and debris could prevent the cooling fans to turn with the best speed and this could lead to a higher temperature which would lead to overheating.
Use a jet of compressed air. I also use it and it helps to get rid of dust and debris.
If this is not enough, then a problem of graphics chip would be possible.
I have a laptop Toshiba Satellite L775. I run Win 7 Home Premium. My mouse pad does not work properly. I also have a Logitech Anywhere MX wireless mouse. I tried the mouse pad to work properly with the key FN and F9, but it does not work. And you really have no idea if that turns or out of the mousepad anyway, subj for another time I guess.
What does not work, but I have to do is to go to Control Panel then mouse option load that and just scroll the tabs without changing what each time and then close and the touch pad works. But only for this session. If I have my laptop nearby, or turn it off, I have to start throughout the whole process.
What's past and how to fix this?
Thank you very much.
> What's past and how to fix this?
After reading your ad, I still don t know what is your problem.
> My mouse pad is not working properly
How to understand this? What does not work properly? What happen exactly when you start your laptop?
I have a Satellite Pro M10 and my infrared does not work. I downloaded the zip file with the drivers from this site. Then, I uninstalled and reinstalled, but it always happens in the Device Manager under "unknown - SMC IrCC - Fast Port infrared (IR Module: HP). (with an exclamation point). When I look at the properties it says under device status:
This device does not work properly because Windows cannot load the drivers required for this device. (Code 31)
Click Troubleshoot to start the troubleshooter for this device.
However, under Driver Details is said:
I extracted the zip file in my home directory of c:\downloads\infrared.
whatever I do, it does not now. It worked when I bought it, but I have too many things on the system for a new installation. Which brings me to another question. Is it possible to re - install windows without losing all your data, etc.? I did it with other systems (95,98) Windows. But it seems that the Toshiba recovery disc means any wiping.
Thanks in advance for any help.
If your HARD disk contains two partitions and you have saved the data on a second you can reinstall the operating system on the first partition using recovery DVDs.
