Choose a computer that:

• meets or exceeds the LENA Hub Computer specs found on your System Requirements document
• can be left powered on, awake, and connected to the internet long enough to complete device processing

An internet connection is required for all steps of processing. If your internet connection is slow or if you'll need to interrupt the connection by transporting the Hub from site to site for processing, be sure to check out the settings options at the end of this article.

1. Click on the fully downloaded installer in the lower left of your Chrome window.
2. Click through the setup wizard, agreeing to any prompts asking for confirmation or permission to install the program.
3. Close the installer when complete.

Why?

If your computer sleeps while working on your LENA files, Hub will stop making progress and your reports will be delayed. The solution: change your computer's power settings so that it does not automatically sleep. You can still manually tell it to sleep...when you're not working on LENA files!

How?

1. Right-click the Windows start button.
2. Choose Power Options from the list.  
3. In Power & sleep settings, click the dropdown arrow to scroll through the options to select Never.

Turn off Autoplay for removable drives so that your computer won't open a File Explorer window every time you connect a recorder.

After installation, open Hub the same way as other Windows programs (icon on desktop or in Windows start menu).

Then log in with your LENA Online username and password.

Hub's default setting is to delete the audio immediately after upload and/or processing.

If you wish to extract and store audio, adjust the SP Program Settings for audio storage accordingly.

Yellow means Hub has detected that your internet is too slow for cloud processing. However, sometimes Hub's internet reading is wrong, so before making any changes try an independent internet upload speed test, such as the one at speedtest.net. 

If the best available Ethernet or Wi-fi connection doesn't meet the 2 Mbps minimum upload speed, you have two options:

Option 1: Set the Hub to process LENA files on the hard drive and send only the small results file to the cloud. This is called local processing. This is the only option if:

• You never have access to high speed internet on this computer.

OR

Option 2: Set the Hub to hold transferred files until you can situate the computer in a location with fast internet. This is called deferred uploading. It is a great option if:

• Hub is on a laptop that goes from place to place, and
• Hub laptop frequently returns to a location with fast internet - for example, each evening it comes back to a central office, main library, etc. You'll just need to open Hub and click a button to make it upload the files when you're connected to fast internet.

A hotspot or Mifi device is fine for transferring devices, but to actually upload the recordings can use up a LOT of data (each file is 1/2 GB!) and it may simply fail toward the end of your billing cycle. If you have not access to high speed internet via Ethernet or wifi, it's usually better to set the Hub to process LENA files on the hard drive. This is called local processing.

If you find that transferred files can't finish uploading within the allotted time at your off-site location, then set the Hub to hold transferred files. This is called deferred uploading. As soon you can leave the laptop sitting in one place long enough to handle all the files, you'll open Hub and click a button to kick off uploading. Note that this works for standard cloud processing or for local processing (if you don't have high speed internet).
