@Archerman61 You may have the mode set wrong or the security to high.

@SaelG Google "tp link ethernet easymesh connection" as I cannot post a link.

@Tico25 I do not know of any specific issue of that router that is open to easy hacking. When you say you changed the password, did you change the WIFI passwords, the router password, the tether app...

@fortsings Many routers allow for the connection of a USB drive that you can use to store information. Some allow for the USB drive to be a Time Machine Backup for Apple MACs but many do not support...
