Ubiquiti AF-4X Radio Firmware 4.0

New Features:

- All New GUI

- Receive Target Power (control tx power to hit remote receive target)

- Slave Frequency Scanning (autoscan of up to 10 frequencies looking for beacon)

- Immediate changes for Basic Wireless Settings; RF link maintained where possible

Improvements:

- Full password length now used (not just first 8 characters) for both web and ssh/telnet

- Addressed issue with unstable (periodic) links when using VLAN priorities

- Ethernet Carrier drop now has high and low trigger points, new timers, etc.

- Various Security Updates

- Improved RF filtering / adjacent signal rejection

- DFS trigger improvements (allows slave unit to use GPS signal) - should configure duty cycle on remote unit

- Tighter timing restrictions for NxN to improve registration timing

- NxN configurations now support DFS channels

- 75% Duty cycle now works correctly with 20MHz and 10MHz bandwidths

Known Issues:

- Spectrum Analyzer still Java based

- If your configuration has ALL three of the characteristics listed:

1. You have inband management disabled

2. You have a management VLAN enabled

3. You manage a remote radio (far side of an airFiber RF link) by connecting the remote data port to the management port either directly or through a switched network

You will need to enable inband management on the remote radio BEFORE you upgrade. After the upgrade, you can then reconnect to the remote radio and disable inband management. Failure to do so will leave the remote radio unmanageable over the RF link (local access via the management port will still function normally).

Notes:

- Recommend updating far end of link before near end

- Only first 8 characters of old passwords are used after update - must reconfigure for longer passwords 

About Range Extender Firmware:

If you intend to apply this firmware, first go to the system information page of the extender and make sure that the currently applied version isn't either newer or matching this release; you should get the downloadable package only after you have done this.

Updating to a new firmware can resolve vulnerability problems, fix various compatibility issues, enhanced existing features, correct different language-related errors, and improve overall performance and stability.

As for the installation steps, since there are numerous extender models, it would be best if you read and, above all, understand the update procedure before you proceed to applying the new firmware; this holds true even if you are a power user.

Bear in mind, that during the upgrade, you mustn't use the device's buttons or interrupt the process in any way. Doing so can cause serious malfunctions to the wireless extender.

Therefore, if this firmware satisfies your needs, get the desired version, and install it to your system; if not, check with our website as often as possible so that you don't miss the update that will improve your device.
