I apologize if this question has been asked (a thousand times) before but my son has a AX1800 router and I want to purchase a range extender for his home. The description on the extenders usually says that " Extend the range of any Wi-Fi router". Am I pretty safe to get any TP Extender for this router? I just want to make sure there isn't any special conditions that would prevent the extender from connecting to the router/network. 

Thanks,

Greg
