Problems Internet connection is an impact of interference experienced at important moments, where

the impact can cause financial losses due to the delay in sending or uploading and downloading a file. Problems

that occur on the internet include not being able to connect to the internet, slow internet connection, so that it

cannot share files in the local network. And this is a factor that decreases performance results in any institution.
