If the WiFi signal in your home isn’t that great and there doesn’t seem to be any technical problem with your router, computer or WiFi provider, it might just be where you have the router located in your house.
If you position your router next to an outside wall, you’ll send part of your signal outside and make it weaker in the rest of your home. Think location, location, location… Place the device so it is centrally located for the devices that will be accessing the signal. I know routers aren’t the prettiest things in the world. But hiding it in the basement with the cat’s litterbox can weaken the signal. This is a case where you should choose function over form.
Keep it away from metal objects like file cabinets. They can wreck your signal. I recently had the experience of having a new whole-house DVR installed. The DVR wasn’t functioning and my WiFi signal was weak. It turned out that my DVR and Wireless Router were too close together and that I’d also plunked a heavy metal candle holder I got for Christmas down beside them. The nice service tech my cable company dispatched to my house said that was probably making it worse.
Short service calls are nice, but I felt a little silly calling someone out to watch me move things farther apart.
