[Known Problems]

  1. Maxtor SATA 3.0G hard disk drives have compatibility issues with N2100 firmware v1.0.5hotfix1 and earlier versions. The symptom may be one of the followings.
    - The RAID formatting process stops at 99% or never completes.
    -The RAID is successfully created but the usable capacity is wrongfully small .
    To fix the problem, you have to upgrade N2100 firmware to v1.0.5hotfix2 or latest one and re-create the RAID.
    1) In case you already put some files into the NAS, backup all of them to other storage devices.
    2) Upgrade the firmware to v1.0.5hotfix2 or the latest one.
    3) Remove current RAID. [Admin Web GUI : Storage / RAID / Config / Remove]
    4) Create a new RAID volume. [Admin Web GUI : Storage / RAID / Config / Select RAID Level / Select Disks / Create]
    If the remove button is grayed out and you could not remove the RAID, you could try installing the disk drives on a desktop computer, manually delete all partitions, and then put them back on N2100.
  2. We strongly recommend upgrading firmware to v2.1.01 or later to fix the security vulnerability of Web GUI. (Thanks to David Karlström for his great help!)
  3. For firmware v2.0.05 and earlier, creating RAID via Setup Wizard may cause improper folders permission; such as public folders need username / password to login. In case you encounter the problem, please contact Thecus technical support team for troubleshooting. However, it won't happen since firmware v2.1.00.
  4. In case the RAID1 was created in firmware v2.0.05 or earlier, the RAID rebuilding process will fail in firmware v2.1.00. Please upgrade to v2.1.01 or later to fix the problem.
  5. iTunes Server needs to cache the ID3 tag of every audio file in iTunes folder whenever N2100 reboots or the iTunes Server was disabled then enabled through Admin Web GUI. During this period, the NAS system has slower response. For the later rebooting, the cache time will become shorter.
  6. N2100 uses open source module to get USB printer server support. So, not all USB printers will work well. In case the printer has compatibility issue with N2100, please install it on a Desktop PC and share it over the neighborhood.
  7. Can not login Web UI when the NetBIOS name is with an underscore.
  8. When any HDD fails in RAID 0 mode, the system will display the warning message but unmount the HDD.
  9. MAC OS 9 Apple network browser sometimes freezes for 5~10 minutes after selecting N4100; however, using afp://IP always works fine on both MAC OS-9/X.
  10. Linux PC could mount public folders and upload files to N2100, but could not download files

[[Known Limitations]

  1. One-button-copy function is limited to front panel USB port.
  2. If AC power lost during RAID building, admin has to manually resume it through Web GUI.
    a) You will see "Total Capacity: N/A" after building process completed.
    b) Manually remove RAID.
    c) Create RAID again.
  3. Supports the following USB wireless dongles only. And it has to be installed before NAS booting up, no PnP.

  14. Some attributes may not be included with files and folders when copying to a USB drive with FAT32 format.
  15. If a USB hard drive is connected to N2100 formatted as FAT16/32, the following restrictions apply:
    - Copy file with size greater than or equal to 2 GB to the N2100 can not be performed due to FAT file system limitation.
    - Files created by Mac OS X like DS_Store can not be copied to the FAT16/32 USB drive.

    - Port 21 is allowed
  32. NAS performance has been improved in firmware v2.1.01 or later. However, it won't take effect just by firmware upgrade; you have to re-create the RAID too. In case you need it, backup all data, remove the RAID, create a new one, and then put all data back.
  33. iTunes Server will periodically rescan the audio files in the NAS and it will affect the disk power management. You may set the iTunes rescan interval longer thus the HDD will get into stand by mode.
  34. Disk Power Management : some HDD may not respond to “idle spin down” command, and they won't get into stand by mode even if the specified idle time had been reached.



  1. During firmware upgrade process, it is imperative that user DO NOT turn off the power to N2100 or closes the browser window. This will lead to catastrophic result.
  2. When installing the Windows Wizard program of N2100 on WinXP Professional SP1 or SP2, the firewall UDP ports 10000 and 10001 need to be opened.
  3. Reset to factory default function automatically resets all the system settings including network settings, administrator password, user groups, language setting, system notification setting, and time zone setting.
  4. Hardware reset button triggers the N2100 to reset its network settings and administrator password.
  5. To avoid accidentally shutdown the N2100, the power button of the N2100 is designed to take effect only when it is being pressed and held three seconds constantly.
  6. Users should obey the international RF regulatory rules as they set up the wireless RF channel on the N2100. The RF operating channels for different regions have been specified as following. Thecus has no responsibility for users attempting to violate the international RF regulation.
