90% of the time, a reboot of your router fixes the problem. Try that first.

The other 10% of the time, there are a few reasons why your Internet connection might drop. Here are the most common reasons and possible fixes:

• Network maintenance. If you experience drops between the hours of 3 am to 6 am daily, it's likely us doing network maintenance. We have a lot of sites that have hardware that needs to be updated, patched, rebooted, etc. We have to do this maintenance during a time that is least disruptive on the network, and these hours are the lowest use times in general.
  
  
• Frequency interference. If we are broadcasting Internet to you on a 5 GHz frequency that is the same as (or close to) the 5 GHz frequency you are using on your wifi router.
  Solution: Please make sure your 5 GHz wifi is set on channel 36. We don't use that channel so it's safe for you to use.
  
  
• Another WISP. If another Wireless Internet Service Provider has a relay near your house, they may be broadcasting a strong signal on a frequency on/near what we are using to provide Internet to you.
  Solution: call us during business hours and we can do a scan from your antenna to see if there's another transmitter we can move you to.
  
  
• Doppler tower. Weather towers (Doppler towers) in the USA have priority over certain wireless frequencies. If you live near a Doppler tower (within a few miles) and we are broadcasting to you on a frequency they might use, you could lose Internet for brief periods of time while they scan the horizon for weather patterns).
  Solution: patience. Dopplers have priority but their weather scans are usually 10 minutes or less, once or twice a day.
  
  
• Internet antenna. It could be out of alignment, has lost its line-of-sight to the transmitter (e.g., tree branch or parked RV in the way), components are failing, etc.
  Solution: call our Office during normal business hours so we can schedule a time for a technician to come out and investigate.
  
  
• Interference. Please see this article for all the things that can affect your wifi signal.
  
  
• An older router. Routers live about 4-5 years. If you have an older router, it may not be able to manage (route) traffic as well as it once did.
  Solution: upgrade to a newer router. Here are some recommendations.
  
  
• Old firmware on your router.
  Solution: Make sure your router has the latest firmware (software).
  
  
• Virus(es) or malware/spyware. One or more devices may be infected. Antivirus software doesn't mean you are protected against getting a virus any more that a flu shot guarantees you won't get the flu.
  
  
• BitTorrent program. If someone is using a BitTorrent program to download movies/games, it could affect network speeds.
