Como Reiniciar Mi Hp Laptop

Netgrears website is horible with no way to contact support. I purchased a EX7300 and it does not tell me how to set up a mesh system. All this unit is good for is an extender with 2 IP addresses not one like the ads state. Trying to even log into the unit is a chore. I have reset the unit three time now and it will now be returned. I have wasted 6 hours trying tom set it up.
