There are some quick fixes that will solve most problems, but you may have to get your hands a little dirty.
1. Try loading the site on a different device.
Try loading the website on your phone or on another computer. If the website loads on the other device, the problem lies with your computer.
If the website doesn't load on another device, the problem is either with the network or the website itself.
2. Restart your computer.
Oftentimes, a simple reboot will fix the problem you're having. Reboot your computer and test the website again.
3. Try loading the site in a different browser.
There may be some settings configured incorrectly on your browser. Try a different web browser to see if you can load the website.

Quick Info
A Speedtest is a service that provides free analysis of Internet access parameters, such as connection data rate.
A Ping Test shows how long it takes for packets to reach host.
A Traceroute Test traces the route of packets to destination host from our server.
The amount you're charged depends on:
- Your contract period and how long's left of your minimum term from the date your subscriptions end, calculated in months.
- Your current box type - Ultra or Ulti/Other Astro Boxes
- The packages you subscribe to, including App services such as Disney+ Hotstar and Netflix
We encourage customers to ensure their TV compatibility with the Astro Multiroom (Smart TV) app first before making any purchase here.
If you are still experiencing any issues, please contact us at wecare@astro.com.my or call or WhatsApp us at 03-9543 3838 and our agents will be happy to assist you.
Multiroom discount rates will be removed upon splitting the account.
Yes, if a device is faulty due to customer's negligence, it is subject to a penalty fee for each device:
- WiFi router: RM200
- Fibre modem: RM500
- Mesh WiFi: RM200/unit
As a rule of thumb, this issue might happen when the devices are not equipped with minimum requirement above that supports the subscribed internet speeds:
- WiFi technology
- Network Interface Card (NIC)
As mentioned above however, it is important to note that despite meeting the device minimum requirements, it is not a guarantee that devices connected over WiFi will be able to achieve maximum subscribed internet speeds due to the following:
- Bad WiFi signal quality and coverage across the area due to:
- Distance from the RGW/Mesh AP with connected device
- Obstruction within the house (walls, metallic surfaces)
- Interference with other household appliances
- Congested bandwidth
- If there are too many devices connected to the WiFi network, then the bandwidth might be overloaded with traffic hence, slowing down the speed
- Devices are connected using WiFi instead of wired using LAN.
- It is important to note that wired connection offers better reliability and speed over WiFi.
- WiFi is more prone to interference compared to a wired connection which causes lower speeds and dropped signal.
- Router Positioning: Most people underestimate the importance of picking a good spot for a Wi-Fi router. Even a small shift in positioning could end up being the difference between day and night:
- High vs. Low: Put the router as high up as possible to extend the broadcasting range of the radio waves. This also helps clear the router of possible interferences.
- Concrete & Metals: Make sure your router isn’t blocked by any other objects, especially devices that are electronic. Also, avoid placing your router in your basement as this area is usually enclosed by a lot of concrete, which can be almost impossible for Wi-Fi signals to penetrate.
- Distance to Router: The further away from your router you get, the weaker the Wi-Fi signal. Therefore, the best option is to place your router as close to your devices as possible, but this is only practical if you have one main area where you tend to use your devices. Otherwise, you should place your router near the center of your home. After all, Wi-Fi broadcasts in 360 degrees, so it doesn’t make sense to put it at one end of the house.
- Usage
- More likely, however, is that the people on your network such as friends, roommates, or family members are participating in bandwidth-heavy activities like gaming and streaming Ultrabox/Netflix.
- Fortunately, if this is the case, you can prioritize your own network traffic by enabling Quality of Service in your router settings.
- If the problem persists, please run a Ping Test/Traceroute Test and attach the picture or screenshot of both test results in the Feedback Form below, in order for us to provide further assistances. Please make sure to attach the required screenshot(s) in ONE file (i.e. Microsoft Word document, PDF, Image file) before submitting the form.
Note:
Astro and its service providers will not offer any guarantees for compatibility of the customer's equipment (e.g., Personal Computer, Notebook, printers) nor provide on site troubleshooting for WiFi service issues related to the customer's equipment.
