The reason why WiFi speeds do not meet expectations is related to these six factors.
1. WiFi Signal Congestion
When users access the internet via WiFi, it is like tuning into a radio station, using a fixed frequency wireless band. Therefore, the number of similar signal transmission and reception devices around the user’s area greatly affects the WiFi experience. “If you live in a central apartment building in the city, and there are hundreds of wireless networks within that building, the WiFi environment will be very poor.”
Even if the WiFi signal bars on your phone are full, the actual WiFi speed may still be very slow, as devices like mobile phones, cordless phones, microwaves, and Bluetooth devices can all affect WiFi signal quality.
2. WiFi Data Latency
The WiFi access method causes more data latency compared to other methods. Moreover, many people using the same WiFi channel simultaneously can significantly impact the WiFi signal strength.
Additionally, if you are in an area with strong network signals, your router will continuously search for the best network channel, which can also cause network latency.
3. Inherent Limitations
No matter how much WiFi technology improves in the future, wireless connections will still struggle to surpass the current wired internet access models. WiFi will not completely replace wired internet connections; it is simply a more convenient networking solution.
4. Background Processes
If your WiFi speed still hasn’t improved after eliminating all the above factors, check if your software is automatically syncing data and photos, as this can impact your WiFi speed. Moreover, since these applications often work quietly in the background, many users may not even remember their existence.
5. Router Placement
The placement of your wireless router also affects the signal strength. For example, if you place your router next to a concrete wall, its signal strength will significantly decrease. Ideally, the best placement for the router is at the center of the house on the ceiling (although many consumers do not have such conditions).
6. Differences in Connected Devices
If your iPhone 4’s WiFi connection speed is slower than that of an iPhone 7, don’t be surprised, as the WiFi connection speed is also greatly affected by the processing speed of the connected device.
1. Upgrade your router to a dual-band router that supports both 2.4GHz and 5GHz frequencies. However, it should be noted that the 5GHz frequency signal does not penetrate walls as well as 2.4GHz, and many older devices do not support this WiFi frequency.
2. Use a channel viewer to check the WiFi channel usage in your area and then choose a less congested channel for use.
3. If you have an idle wireless router, consider using it to extend or amplify the indoor WiFi signal strength.
4. If your router offers different power usage options like high power and low power, typically the low-power option will provide better WiFi signal strength.
