WHAT HAPPENED TO THE WIFI SSID WHEN BAND STEERING IS DISABLED?

When Band Steering is disabled, you will see two separate WiFi SSID based on its frequency bands. Example:

i. SSID: SSID2G, Password: 1234567

ii. SSID: SSID5G, Password: 4567890

*WiFi SSID (Service Set Identifier) is the name of your wireless network, also known as Network ID. It is viewable to anyone with a wireless device within reachable distance of your network.


WHEN WILL THE 2 MONTHS ACCESS ON PRIME VIDEO WILL EXPIRE?

The 2 months of access will expire exactly two months after your account is activated. For example:

  • If you activate on 24 April 2025, your access will expire on 23 June 2025.

WHAT IS THE PROCESS OF TERMINATING ASTRO ACCOUNT?

Below will be the process to terminate Astro account:

  1. Account holder to give 30-day notice period for account termination.
  2. Account will be scheduled for termination 1 (one) day before customer’s billing cycle date.
  3. After account terminated, there will be a collection of Ultra/Ulti box and Broadband Equipment.

Notes: You need to settle the outstanding balance and penalty (if any)

Ultra/Ulti Box retrieval:

  • West Malaysia except for East Malaysia, Tioman, Labuan and Langkawi – Courier partner will contact customer for box retrieval.
  • East Malaysia, Tioman, Labuan and Langkawi – Installer will do the box retrieval.
  • For other than Ultra/Ulti box, refer to recycle information here.


Broadband Equipment retrieval:

  • Installer will do the equipment retrieval.


WHY DOES ASTRO RECOMMEND THIS FEATURE TO BE DISABLED?

While this technology has its benefits, different devices at home have different reaction and response to changes in signal strength and quality, and it's almost impossible to predict if they will make good band choices due to the interaction between the devices and the Wifi router. Some smart home devices also recommend that band steering is not used due to various reasons such as needing a constant consistent connection, ability to only connect to a particular band, registration of the respective MAC address, etc..

Example:

As single SSID is used, the device may remain on a weak 5GHz network instead of switching over to stronger 2.4GHz network.


HOW WILL THIS PRICE INCREASE AFFECT MY BILLING CYCLE?

There will be no changes to your billing cycle.


HOW CAN ASTRO CUSTOMERS ENJOY WETV?
