Slow browsing using Wi-Fi
1. 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.
i) 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.
ii) 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.
iii) 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.
2. Wireless Interference & Noise
You've probably never noticed but there are wireless signals all around you wherever you go and they're passing through you all the time. From where? Electronic devices, Wi-Fi routers, satellites, cell towers, and more.
Although Wi-Fi is supposed to be on a different frequency than most of these devices, the amount of radio noise can still cause interference. Some common causes of interference include:
i) Microwaves
ii) Bluetooth Devices
iii) Cordless Phone
3. Surrounding Wi-Fi signals
A truth of the modern world is that every household has their own Wi-Fi network, which can cause issues with channel overlap. This can be somewhat problematic in a townhouse, but is especially problematic in housing complexes and apartments where there can be many routers within close proximity.
Which is why it's important that you pick a good channel in your router settings. Modern routers can choose channels for you automatically, but sometimes it's better to investigate and find the best channel yourself.
4. 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, 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.
