I know nothing about networks and internet. This point has been reinforced when, after days of trying to install my new TP Link Wifi Router AX20 to my network, I am told that I need a modem before it will work. On further reading, I now have a choice of purchasing a DSL Modem AND a Wifi Router OR purchase a combined Modem Wifi Router. I should add that it is a home network for a family of 5 adults including one gamer, 3 film-watchers and a tv sports fan. The house is old and large with 4 bedrooms on 3 levels. All floors have foil-backed solid insulation that plays havoc with wifi although it did work with extenders before. I also purchased 2 TP Link Wifi 6 AX1500 Extenders that provide a OneMesh coverage.
Can anyone provide step by step advice on this? Thanks you.
