Wi-Fi in Rain: Raindrops normally do not affect mobile internet or Wi-Fi so much that its speed decreases.

(Why does WiFi speed slow down in the rain?)
Wi-Fi in Rain: It's often seen that internet speeds slow down during the rainy season. This impact is evident not only on mobile data but also on Wi-Fi. Many people believe that networks slow down during the rainy season, which is why the internet doesn't work. But is this really true? Let's find out why Wi-Fi slows down during the rainy season.
What is the connection between rain and the internet?
In fact, raindrops don't normally affect mobile internet or Wi-Fi enough to slow down its speed. Mobile networks use radio signals, while Wi-Fi also operates on wireless radio frequencies.
While light rain doesn't significantly impact these signals, heavy rain, thunderstorms, or other inclement weather can impact other parts of the network, leading to slow internet speeds for users.
Rain isn't the only reason Wi-Fi slows down.
If your home Wi-Fi is slowing down during the rain, it's not necessarily due to the Wi-Fi signal itself. The first step is to check if the connection from your internet service provider to your router is working properly.
Additionally, failures in fiber lines, local cables, or other network components can also slow internet speeds. External network infrastructure is especially vulnerable to damage during heavy rain and storms.
More people are using the internet at the same time
For your information, during the rainy season, people often spend more time indoors, in their homes, shops, and offices. Now, in their free time, people tend to use the internet more, which directly results in heavy network load. When many people in the same area simultaneously watch videos, use social media, play online games, or make video calls, the traffic on mobile towers increases.
Now, the tower's power is limited. When this extra load is placed on the tower at once, some users may experience slow internet.
Mobile signal may also be affected.
Mobile networks rely on radio waves. Heavy rain and bad weather can affect signal quality on frequencies. If network coverage in an area is already weak, internet speeds may automatically slow down during bad weather .
An electricity problem can also be the reason
Rain can also cause power outages or voltage fluctuations in many areas. If your router, modem, or network device isn't receiving balanced power, it can cause connection problems.
Sometimes the device doesn't shut down completely, but the network connection becomes unstable. In this case, the user experiences slow internet speeds or frequent connection drops.
Impact of backhaul network failure
Mobile towers alone don't deliver internet to users. In fact, fiber or other backhaul connections are needed to connect the tower to the main network.
