Few household appliances may make you feel as frustrated or perplexed as a router with a poor WiFi signal. You find yourself huffing as websites load on your laptop, fidgeting as YouTube videos stop on your tablet, and starring in despair at email inboxes and social media feeds as they struggle to refresh on your smartphone if you don’t have a fast and consistent internet connection. What about watching the most recent episode of “WrestleMania” on your smart TV? Put it out of your mind. To add to your anxiety, you might not know how to fix the issues—other than dialling a tech-savvy relative and begging for assistance.   According to Professor Bhaskar Krishnamachari of Electrical and Computer Engineering and Computer Science at the University of Southern California, “WiFi is electromagnetic radiation, just like light.”. “Some items obstruct it, while others allow it to pass.” Here are some common roadblocks to consider when setting up routers and using linked devices. We’ve set up a three-piece mesh router network in this diagram to assist avoid any dead spots in a multilevel home.   According to CR’s Fisco, the hub should be placed in the centre of your home (1) and between the satellites (2 and 3). Note that satellite 3 is located distant from the refrigerator on the kitchen counter (4). To avoid dead zones, WiFi signals from the hub and satellites can move up and down the floors.   The Walls   According to Krishnamachari, thicker walls absorb more WiFi signals than thinner walls. While you can’t readily adjust the thickness of your walls, relocating a mesh satellite closer to the room’s entry can assist enhance the signal. The Refrigerator   A refrigerator, as well as other appliances with a lot of metal, might cause problems. Instead of flowing through to the opposite side, WiFi signals may bounce off them. Metal plumbing and rebar in your walls can also cause issues.   The People Next Door   If you reside in an apartment building or a densely populated area, wireless congestion caused by nearby devices operating on the 2.4GHz frequency band may be a problem. Switch your router and other devices to the 5GHz frequency band, which has a lot more channels. Select a different channel in the device’s settings if your network doesn’t support 5GHz.   Microwave oven   Microwave ovens, Krishnamachari points out, also use the 2.4GHz frequency spectrum. If you decide to cook a second bag of popcorn while watching a Netflix movie, for example, this can cause interference, he explains. Switch your laptop or smart TV to the 5GHz frequency to eliminate interruptions during movie night.   The Aquarium   Krishnamachari claims that water absorbs radiation. As a result, your WiFi connection is likely to be disrupted near swimming pools, hot tubs, and, yes, that 100-gallon fish tank you put in.    A new modem from should be your first line of call if your current one isn’t working properly.
