GENERAL INFORMATION

1. What is the NMH Series?

The NMH Series is a Media Hub that serves as a Home Entertainment Storage with a 500 GB drive.  It is designed to store your media content including music, photos and videos in one location for convenient access.  You can copy files from a computer or other network devices directly to the Media Hub.

NOTE:  The NMH300 is shipped without the 500 GB hard drive and a separate hard drive should be installed manually.

2. Does the NMH Series require a password when you login?

Yes.  The default password is “admin”.

3. Can I access the NMH Series from a web browser?

Yes, by performing the steps below:

Step 1:
Open your web browser.

Step 2:
In the Address field, enter ONE of the following:
"http://<Friendly_Name>" or http://<IP_address_of_Media_Hub>

Step 3:
Press [Enter].

4. Where do I place video files that I've copied from the computer?

Open the media\videos folder of the Media Hub.  Then, go to Edit and click Paste.

5. What backup options are available for the NMH Series?

You must first install the backup software provided in the Setup Wizard.  You can then create and schedule backup jobs.  If at any point of time you want backup to be performed immediately, you can press the Backup button located on the front panel of the Media Hub.  Backup jobs created earlier will then be initiated automatically.

For further information on how to backup media files on the NMH, click here.

NOTE:  The computer must be powered ON for backup jobs to be performed.

6. What is the warranty period for the NMH Series?

The warranty period is dependent on the country of purchase.  For more information about your device's warranty, click here.

7. Why is the Power LED of the NMH Series flashing amber?

The Power LED flashes amber when there is an error.  

8. What are the security features supported by the NMH Series?

There is password protection for Security Administration, File Access and Remote Access.

9. What are the memory card file types supported by the NMH Series?

Secure Digital (SD), MultiMediaCard (MMC), extreme Digital (xD), Memory Stick (MS) and CompactFlash (CF).

10. What does Re-Scan mean in the Media Hub?

The Re-Scan button refreshes the Media Hub's index of media files.

11. What are the basic functions of a Network Media Hub Fan?

The fan inside the NMHxxx will spin at different speed while the unit is powered ON.  The fan spins at a dynamic speed and is usually running around 10% speed in idle mode.  The fan control is programmed to keep the internal temperature below 50 degrees Celsius.  If the NMHxxx reaches 65 degrees Celsius or higher, the unit will shut down.

12. Is Adobe Flash Player supported for playback in a 64-bit browser?

In order to use Flash Player to view Flash content on a 64-bit operating system, you must run a 32-bit browser.

13. What operating system does the NTI Shadow support?

The NTI Shadow runs on Windows XP (32 & 64-bit), Windows Vista (32 & 64-bit) and Windows 7 (32 & 64-bit).

14. I've enabled 'Find Shared Media on My Local Network' and the UPnP crawl has begun.  Now I need to shut down my computer while the music is being indexed.  Will the indexing continue from the point of shutdown?

If the indexing is not complete by the time the computer is shut down, indexing restarts when the computer is once again available.

15. How are video thumbnails generated in the Network Media Hub?

The Media Hub decodes the first five (5) seconds of each video and randomly selects an I-frame, then creates a thumbnail.

16. How does the Media Hub know what album art to display for a track or album?

Media Hub first searches for the AMG database for the album name in the track metadata, followed by the artist name (maximum of 100 hits).  If this fails, the Media Hub displays a photo of the artist based on the artist metadata.

17. What language does the Import Tool Support?

The languages supported by the Import Tool are:

USCA - English
French EU - English
French
Spanish
Portuguese
Danish
Italian
Swedish
German

18. How does the Device Language in the NMH4xx series work?

The NMH4xx has the option for nine (9) languages in the NMH User Interface.  Once the Device Language is changed, the language in the LCD Menu will change accordingly.  The Device Language feature only applies to the LCD Menu on the NMH4xx series.

However, the language on the computer or the NMH User Interface will not change unless the computer's language has been changed.  The computer's operating system dictates which language will appear on the User Interface.  For example, if the computer's language is in French, the language on the NMH User Interface will automatically be French.

When the language has been changed in the NMH User Interface, the computer screen will keep the new language until the web browser window is closed.  When the web browser window is opened again, the language of the computer’s operating system will appear.

19. How many characters can be used when creating a file name on the NMH?

The maximum amount of characters allowed is 32.

20. What is the purpose of the Eject function for USB devices?

Some files on your USB device might still be in use or open by the system.  Therefore, you need to select the Eject button on the main page for the USB storage device to be properly removed.

21. Why do apostrophes in files or folders make parent folders and files unreadable?

The Media Hub does not support the use of apostrophes in file and folder names or the device itself.  Rename any items that use apostrophes in their names.

22. Why are the dates shown for Photos in the File Browser correct, but incorrect for the Photos in the Media Library?

The Media Hub uses the date information stored inside the media files.  If no date exists, then the Media Hub uses the date of the media file itself.  For example, if a digital camera stamped a picture with an invalid date, then this date may be used when the Media Hub sorts the photo in the File Browser, even if the file import date differs.

23. When uploading of a large file from a PC to the NMH, why does the UPLOAD function in the File Browser show all bytes transferred but not completed?

During the uploading of large files, these files may not be available for cancel or use until the internal uploading process is complete.

24. Why is M4a playback "choppy" during remote access?

Depending on the media player used by your web browser, M4a playback may be choppy.

25. Why does the setup wizard for NMH4xx fail to find the Media Hub if the WHA DMRW1000 wireless handheld device is connected to the PC's USB port?

Before you run the Setup Wizard, make sure your computer has an active network connection to the router.  If your computer has more than one (1) network adapter, disable the inactive network adapter.

26. Why are the first few characters of the Media Hub name blocked in the Web-Browser's display?

To avoid a wrap around issue, limit the Media Hub name to 15 characters.

27. Can I use special characters such as the equal (=) sign and at (@) sign when creating a password?

No, the equal (=) sign and at (@) sign are not supported if used in a password combination.

28. What is the maximum character length for the password?

The length for the password has to be from 4 to 15 characters.


CONFIGURATION

1. Can I access the NMH Series remotely?

Yes, but Remote Access must first be enabled on the Media Hub.  By default, it is set to Disabled.  

2. In the web-based utility of the NMH Series, how do I change the layout view to list and album art view?

Click on the Grid or List icon located on the lower left corner of the Media Hub screen, to toggle between list and album art view.

3. How is a slideshow created for Photos in the Media Hub?

A slideshow is created for every folder of pictures in the Media Hub.

4. How to access the Media Hub over the Internet without using the Remote Access feature of the device?

In order to access the Media Hub over the Internet without using the Remote Access feature, you must forward the ports 443, 80 and 9000 on your home router.  After forwarding these ports, access the device using HTTPS://WAN_IP_Address.  Without using HTTPS, you will not be able to play any music or view any video files saved on the Media Hub.

NOTE:  While using HTTPS, you will be unable to access the configuration page of the Media Hub.  To learn how to set up port forwarding, click here.

5. I'm using Increased Protection mode, but I want to make an additional backup.  Can I remove one of the disks and archive, then put in a new disk and select Rebuild?

Yes.  Replacing Disk 1 will take five (5) minutes longer for the disk to come back up and begin the rebuild process.  The NMH firmware then resides on Disk 2.  In addition, if updates to the firmware have been made since the Media Hub was first installed, you must manually update the firmware to the latest version or wait one (1) week for an auto-update to take place.

NOTE:  Since NMH system files reside on Disk 1, users should consider choosing Disk 2 to archive and replace.

6. File types or extensions are not recognized properly in the Media Hub browser.  Can I still play files that have an .exe extension?

You may see .exe as a file type in the Media Hub browser, but this will not affect the ability to play your file if the actual file type listed in the file name is supported.

7. How can I recover my lost password?

If your password is lost, you will have to go back to the computer that was used in running the Setup CD installation of the Media Hub and look for the Notepad document that contains the friendly name, IP address and password.  Otherwise, you need to reset it.

NOTE:  Resetting the Media Hub will only restore to defaults the basic configurations like password to the UI, IP address, and time. The files and disk configuration won’t be affected.


TROUBLESHOOTING

1. What should I do when I can't access the web-based utility of the NMH Series?

You should use the router's web-based setup page to check the IP address currently assigned to the Media Hub.  Then, use that IP address and try to access the Media Hub utility again.

2. What should I do when the message "High Temperature Detected" appears on the LCD Menu of the NMH Series?

Make sure that there is nothing blocking the air vent on the back of the Media Hub, which can lead to overheating.  Then, press OK to exit the screen.

3. Why is there a delay in showing the pictures when I remotely access the Media Hub?

The delay is due to the fact that the image files needs to be downloaded first before it can be viewed.  The speed of the download will be determined by the upload speed of the Internet connection being used at the Media Hub site.

4. Why do some album art show up while others don't in the Media Hub?

The files with no album art probably haven't been tagged yet.  Every music file needs to have the proper tagging in order for the album art to show up correctly.

5. Why don't I see any changes on the NMH after upgrading the firmware?

The browser cache needs to be cleared after upgrading the firmware to the NMH.  This is essential for new features to appear on the Media Hub's interface.

6. Why are the computers on my home network getting a message about the NMH?

The message you receive on your home network about the Media Hub is the UPnP discovery message.  This message is basically the Media Hub advertising itself on the network.

7. The playback of Windows Media files (.wma, .wmv) in Firefox requires a third party browser plug-in.  Why does the plug-in work fine when playing Windows Media files locally, but does not support playback over https?

Due to technical limitations with a Windows Media Player plug-in, playback of Windows Media files in Firefox is not supported over Remote Access.

8. Why doesn't the video file play via the computer's default media player application or via the Network Media Hub's interface?

The correct video codec must be installed for the computer's default media player to enable the video to be played.  This includes playback for the NMH, too.

9. How do I determine which codec is required by the video file to be installed?

You can use the application, gspot to inspect the video file and display the codec required to be installed.  Download the application from http://www.headbands.com/gspot and use the File menu in the program to load the video file.  Observe the upper right section of the gspot application for the codec required.

NOTE:  Since there are many types of video files, the best place to find a specific codec is by performing a Google search.  Linksys does not offer any technical support for codec/player installation or configuration.

10. When I'm using the Photos application to view my pictures, some of the pictures need to be rotated.  How can I rotate the pictures so that the orientation is correct during a slide show?

You can use your existing photo editing software to rotate the photos to the correct orientation, and then update the newly edited photo to the Media Hub.  The Photos application is designed for photo viewing only and does not come with any photo editing tools.

11. Why is it that during the Media Hub detection in the Setup Wizard, the wizard instantly displays 'Error 100 - No Device Detected' message?

The error message indicates that the computer has lost its connection to the router.  Check the wired or wireless connection to the router and re-establish the network connection.  Once the connection has been repaired, click Retry on the Setup Wizard to reload the Media Hub detection.

12. How to resolve the issue Error 107 on a laptop installed with Security Agent during installation of the NMH?

Disable the Security Agent shown in the system tray as a red flag.  Right-click on the icon and select Security Level. Select OFF.  After the installation, user can turn ON the Security Agent by repeating the previous steps.  Select Medium or High whichever was previously selected.

NOTE:  For more information, you can call the toll-free VIP number 1-866-509-7452 (Toll free from U.S. and Canada).

13. Why does my Firefox browser session crash?

Disable Piclens Add-on from Firefox. Piclens has issues with Flash-based web sites and will crash the browser.  NMH can be used directly from the browser and the web-based access page is built based on Flash therefore Firefox with Piclens Add-ons will crash when accessing the NMH web-based utility.

14. Why is it that the audio is still playing after the video has been closed?

Internet Explorer 7.0 and 8.0

Users may continue to hear the video audio track if video is not properly exited.  When user plays video and then abruptly closes the video play window without exiting, the audio track may continue to play until user selects another video or the video ends.

Mac OS® 10.4.11 running Safari® 3.0.4 and Mac OS 10.5.6 running Safari 3.2.1

When a user clicks the Close button directly, the video closes but the audio keeps playing until the end.  You have to open another file, click Play, then click Stop, and lastly click Close.

This is a Safari Flash issue and it is fixed for the Mac 10.5.6 running Safari 3.2.3, but not yet for Mac 10.4.11.

15. Why does the NMH reboot when I enable Remote Access?

When you enable Remote Access for a new ID, the device downloads a new "https" certificate and reboots.  If you are re-enabling Remote Access for the same ID you had before, the device doesn't grab a new certificate and doesn't need to reboot.

16. What could be the cause if the name of a USB storage device connected to the Media Hub is displayed in a foreign language?

If you have a USB storage device connected to the Media Hub, its name may not display properly if it is in a non-Western language.

17. What should I do if I get an error when moving folders from external storage device to the Media Hub?

You can only copy (not move) files and folders from external USB storage devices, such as USB flash disks or USB hard drives, to the Media Hub.

18. Why do I receive an "Operation Failed" error message at several instances on the Media Hub web-browser?

When you move large amounts of data to the Media Hub, it will be busy processing the data import and preparing the media files for the Media Browser.  If you attempt to use the Media Browser or Configuration utility at the same time, then the Media Hub may become unresponsive, or a message, "Operation Failed", may appear.  Wait a few minutes and try again.

19. During remote access on either Windows or Mac OS, uploading of 20 M4a files takes 32 minutes to complete.  Is there a way to increase the uploading speed?

Upload of large amounts of data over remote access may take a long time to process, depending on the broadband speed of both your home connection and remote connection.

20. Why does the installation software wait 15 minutes if the user selects "I have more than one Media Hub" on a computer?

If more than one Media Hub is present, it may take up to 15 minutes for the computer to complete the discovery.

21. File and folder copying in File Browser allows duplication of files.  How do I rectify this?

You can use Windows Explorer (for Windows OS) or Finder (for Mac OS) to delete duplicate files.

22. Why is the playing screen sometimes out of its player frame when playing a video?

When playing videos with certain older graphic cards (NVIDIA GeForce 4200) the video may appear slightly out of the media player's frame.
