I just purchased an AX1500 to add to my home wifi. I was having many drops with my xfinity cable modem wifi router. I hooked up my AX1500 to the existing cable modem using the WAN port on the AX1500 and turned off the wifi feature from the cable modem. Are there any settings on the AX1500 i should change besides the default settings? Should it be in (Wireless router mode) or (access Point Mode)?
