WHY INTERNET GOES DOWN?

 

The most common cause is a problem with your router or modem, or a loose cable, but your internet can also fail because of a more technical reason.

 If you're on a wireless connection, try plugging in with a cable. Next, unless there's good reason you cannot or should not do so, try restarting your computer and, if applicable, your router and/or modem. Restart, not reset: just unplug them, wait 30 seconds, then plug them back in again and let them reboot confirms Google when wifi connections  are not well.

For most homes with regular Internet use, speeds between 25 Mbps to 100 Mbps are just right. Slow lane. A low bandwidth is typically considered to be less than 10 Mbps.

Routers tend to spread their strongest signals downward, so it's best to mount the router as high as possible to maximize coverage. Try placing it high on a bookshelf or mounting it on the wall 

There could be a number of factors that affect your internet connection. First, and most likely, is problems with your equipment. Restarting your modem/router should resolve the issue. Other reasons why your internet may keep going out include inadequate speeds, network congestion and inclement weather.
