Hi, my wife got sick quite a few years ago and I slowed way down when she went to a nursing home. I want to get things running again. I used to use IPcop. Can you suggest another firewall/router for a basis home system. I installed Linux Mint 20.2 on my computer and have an old WRT54G2 wireless router for my phone and tablet. I know this is not very secure. My computer does not have any ports open as I don't play games or anything. I was wondering if the Microtik RB750GR3 hex router reviewed by thiggins would work as a cheap basic firewall/router. And should I replace the WRT54G2 or can I reuse it with a very long password behind the RB750GR3 router. I am almost 70 but I love learning about Linux, security, and networking. I remember following Phillip and yeoldstonecat years ago before my wife got sick. I took some class in Linux and networking in the early 2000s. I had to stop after the first semester of Cisco Networking. Thank you for listening and any help you can give me.
