Upgrade Information
In order to ensure compatibility between your devices, both the Neutron Switch and Neutron
Access Point must both operate under c1.6.x.
The following EWS versions can be directly upgraded to version c1.6.x:
 c1.0.6
 c1.0.9
 c1.3.x
 c1.5.x
If your device is running an earlier version which is not listed above, you must first upgrade
to one of the versions above ahead of upgrading to this release.
Your devices can either be upgraded manually from the device GUI or by using the
One-Click Update function on the EWS Switch.
Naming rule for CAPWAP version
cX.X.X
First digit: protocol design change
Second digit: feature change
Third digit: bug fix
The EWS Switch and EWS AP are only compatible if the first and second digits are the
same.

Enhanced & New Features
This section contains enhancements and new features that have been applied to the
Neutron Series in this release.
1.
Background Scanning
With Background Scanning enabled, the controller periodically samples RF activity of all
Access Points including channel utilization and surrounding devices in all available
channels. Background scanning is the basis of Auto Channel, Auto Tx Power and
Rogue AP detection, and must be enabled for these features to operate. You may, if you
prefer, disable it if you feel it's not helpful, or adjust the scanning frequency, if you want
scans at greater or fewer intervals.
Note: For latency-sensitive applications such as VoIP, it is recommended to set the
background scan interval to a higher value, e.g. 5 or 10 minutes. For regular application,
the recommended value is 30 seconds. This value will also be directly related on how
long it takes for the AP to scan for rogue devices.
2.
Auto Tx Power
Using the information collected by Background Scanning, APs can automatically adjust
their transmit power to optimize coverage. When enabled, APs will optimize their
transmit power based on the time interval configured for Background Scanning.
Note: Background Scanning must be enabled and Transmit Power of APs must be
set to Auto (under Wireless Radio Settings) for this feature to operate.
3.
Auto Channel Selection
Using the information collected by Background Scanning, the controller has the channel
utilization statistics of all channels. With this info, APs will be able to automatically adjust
their radio channel for the best channel utilization and performance.
Note: Background Scanning must be enabled and Channel of APs must be set to
Auto (under Wireless Radio Settings) for this feature to operate.
4.
Hotspot Service
A hotspot is a wireless network that provides access through a captive portal. A captive
portal provides registered users with network access while containing unregistered

users. Users will need to enter a valid user name and password before they are allowed
access to the Internet through the hotspot. c1.6.x supports authentication using the
controller’s internal database as well as authentication using an external RADIUS
server.
5.
Migration to ezMaster
This feature will help to migrate the EWS Switch and all the APs managed by the EWS
Switch to ezMaster automatically without the need of manually entering the check code
and MAC address of all the APs one by one.
6.
New Band Steering Algorithm
Once enabled, when the wireless client first associates with the AP, the AP will detects
whether or not the wireless client is dual-band capable, and if it is, it will force the client
to connect to the less congested 5GHz network to relieve congestion and overcrowding
on the mainstream 2.4GHz frequency. It does this by actively blocking the client's
attempts to associate with the 2.4GHz network. The 3 modes available in this release:
 Prefer 5GHz: All dual-band clients with 5GHz RSSI above the threshold will be
connected to the 5GHz band.
 Force 5GHz: All dual-band clients will connect to the 5GHz.
 Band Balance: Automatically balances the number of newly connected clients across
both 2.4GHz and 5GHz bands.

IMPORTANT INFORMATION: Band Steering only defines the action when a wireless
client associates with an AP for the first time, and the wireless client must be in both
2.4GHz and 5GHz wireless coverage zone when authenticating with the AP for the
Band Steering algorithm to take effect.

Known Issues
This section lists the known issues in this release.
1. Client Interoperability Issue
 Apple iPhone 6/iPad Air 2 running iOS 9, iOS9.1 unable to connect to a captive portal
enabled guest network.
2. Fail to send mail
 Email Alert using a Gmail account does not work. Click on Test button gets result: “Fail
to send mail.”
Resolution: Use port 587 instead of 465.
 Change TSL authentication security level for your Gmail account
at https://www.google.com/settings/security/lesssecureapps. "Access for less secure
apps: Turn on"
