Rain, according to the review site Techwalla, has an influence on Wi-Fi signals, "especially for wireless systems employing the 2.4-GHz radio band." "Water droplets absorb this radio frequency and partially block the transmission," the website states. "This is why you can't have a wireless router in a bathroom -- even if there's no water damage to the walls or floor."
The problem with this type of coverage area is that it leaves large areas without connectivity. So if you want to be sure that you have good service where you need it, it's best not to deploy Wi-Fi in areas where it might get blocked by moisture.
This is not to say that you should avoid deploying Wi-Fi in bathrooms or other areas where it could be blocked by moisture. Rather, you should try to deploy it in an area where there's no chance of interference from other devices. A router mounted on the wall above a bathtub, for example, would be well positioned because it wouldn't be affected by water droplets on the floor below. It would also be easy to maintain cleanliness over time.
In general, though, if you can avoid it, we recommend avoiding deploying Wi-Fi in areas where it might get blocked by moisture. The last thing you want is to create a gap in your network coverage due to environmental factors beyond your control.
Water can also slow down Wi-Fi speeds. Assume your room is really filled and you're throwing a party. According to Kalle, this can really reduce the strength of your Wi-Fi connection. Humidity can also have an effect on Wi-Fi speeds, although not significantly enough for the ordinary user to notice.
While rain can cause interference, much like it does for human vision, attenuation due to distance from the router is a much more likely cause of low signal strength, according to Techwalla. In other words, sluggish internet and terrible weather are examples of correlation rather than causality. The reason is simple: Water tends to conduct electricity, which means that a network cable running near water may not be as protected from exposure to electrical current as one that is not close to any water.
In addition, moisture in the air will increase the resistance between wires, causing less voltage to reach the end device. This effect becomes more significant at higher frequencies because more power is needed to transmit data at high speeds. Finally, if a node on the network is flooded, its connections will be unable to communicate with other nodes, which will cause delays while they re-establish connections.
If you're experiencing slow speeds during heavy rains, there are several possible causes. First, if you live in an area where flooding is a problem, make sure that you don't have any cables running under floors or behind walls because even small amounts of water can cause these types of circuits to short out. Also, keep in mind that if a tree falls on a power line, this could also cause power outages.
In most circumstances, a wet day or a little snowfall will not disrupt your internet service. During strong rainstorms, satellite internet, television, and mobile phone services may be disrupted. Other atmospheric occurrences can also create intermittent internet connectivity. For example, lightning strikes can damage electrical lines that connect to your house, which can cause your modem to reset itself and lose its connection to the web.
If this happens often, call your internet service provider immediately to have your line checked for damage. If the problem persists after such maintenance work has been done, then there is probably something else wrong with your connection. For example, if you use your modem as your only means of accessing the internet, but it keeps losing contact with its host server, then you might need to replace it.
The people who design satellites know how much water can fall on them before they break. Satellites are designed to operate in extremely dry conditions (as well as being exposed to direct sunlight for many hours at a time). Therefore, when it rains heavily for several days in a row, it can cause problems for wireless internet services. These problems include flooding on residential streets with poor drainage, which can lead to damage to porch lights, street signs, and other objects; increased traffic accidents due to reduced visibility caused by flooding; and increased risk of fire because of the presence of hydrocarbons in water.
Stormy weather may degrade free Wi-Fi hotspots around your area, and it can even cause your home Wi-Fi network to go down. In general, the intensity of the Wi-Fi signal from your router to your device is unaffected by the weather (barring some slight interference during high humidity). However, rain does change the radio frequency (RF) quality of the air, which could affect other wireless devices in your house.
If you are one of the many people who use Wi-Fi hotspots provided by restaurants or hotels, there's a good chance that they were once public access points that have been switched over to private mode. These areas try to protect their investment by shutting off their access points when severe weather is expected, to avoid disrupting their customers' connections.
In addition, heavy rain can cause trees to drop their leaves onto electrical lines, which can lead to power outages if not corrected soon after a storm. This is another reason why businesses might shut down their Wi-Fi networks during thunderstorms.
Finally, lightning can strike nearby antennas on fiber-optic cable or utility poles, causing them to malfunction or be destroyed. This would also explain why companies might turn off their Wi-Fi networks during cloud-to-ground storms, since fiber-optic cables are usually kept away from buildings in order to prevent this from happening.
