I have been meaning to do this for a while. The old one still worked but I wanted a stronger signal, more speed and range. It is ironic that most of my life was in IT, but I have been running older stuff at home.
In case anyone is thinking about upgrading their wifi also, this is a good choice and cost effective. This is not an affiliate link and I do not make a penny off it. https://www.amazon.com/gp/product/B01LXL1AR8/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&psc=1 This supports all wifi standards (b,g,n,ac), and dual 2.4 and 5 Gh networks.
A big plus for some - it is super easy to configure a true GUEST network. Guests can use the Internet but your wifi is private. It also allows bandwidth controls, so a guest can’t use the entire connection - or use more bandwidth than you wish. This can be pretty useful for some countries, where bandwidth is expensive and/or limited.
