Hi there
I just took 10 minutes to read every answer and comment on this and here is you can solve the problem.
Dropping the internet or connection can be a difficult thing to locate because of the devices involved. here is how you do it =
***Connectivity distance -*** if your printer is away from the router depending on your router range then this may be the cause of the issue. if there are thing walls it also causes interference in wireless connection. please Bring the printer or router closer to each other or install a wifi range extender.
***Outdated Printer or Router driver-*** please update the router firmware or printer driver to make sure the technology and compatibility are in sync.
***Encryption Type -*** some printers do not support or work well with diffrent types of encryption types or security protocols and this very well could cause frequent connection with in printer to the wifi network.
***IP Conflict -*** if your printer is assigned the same IP like any other device in your network by your wifi router then this very well could also cause trouble. please log in to the router and check for the issues.
if the above solution does not solve the problem try the reset the printer and reconfigure it from start.
there are many ways and methods to connect the printer with the router. here is the best methods to configure the [link|https://printerhelps.net/how-to-connect-brother-printer-to-wifi/|connect brother printer to wifi network] and if recommend using the WPS method to connect the printer with wifi for better connection.
