Looking to buy the NETGEAR - Nighthawk RAX45 AX4300 WiFi 6 Router

[heshie75v]

     Must I have a cable modem to install this router, or is it enough to have a Cat 5 ( I believe its called Cat  5 ) cable coming into my home directly from the OEM that Hotwire communications installed in my home. 

I currently have an old Buffalo Router which seems to be failling after about 10 years, and want to replace it with the Netgear.

Thanks

Must have a cable, DSL or Fiber ONT to connect with any external WiFi router that has a RJ45 WAN port connection.

Netgear has set up a community forum specifically for the NightHawk RAX WiFi 6 Router products. Might be more likely to find someone who has a solution if the question is posted there:
