Troubleshooting questions/steps:

  • Where is your home router located in your home, is it sitting next to an adjacent exterior wall? If so you might want to consider moving to a more central location so you can get a more even coverage throughout the home.
  • How far away are you from the router? Can you move closer or even hardwire in with a Ethernet cord to see if you can get a better connection?
  • Is the router near a TV or microwave oven? These can cause interference with the connection on devices.
  • How many people/devices are connected at the moment? Can you disconnect some to see if your connection improves?
  • Have you tried to reboot your home network?
  • Do you have a 5ghz network connection? Some home networks come with 2.4ghz and a 5ghz. If you do you can try to connect to the 5ghz, so there is less interference?
  • Lastly have you contacted your provider to see if there is a problem on that end or something they can do to prove your situation.
