How Do I Increase Security on My Own AT&T Fiber Home Network?

Probably a newbee question...

I have AT&T Fiber for the home. I have four laptops and several other devices (e.g. cell phones, home security/automation) connected via WiFi and ethernet. How can I secure my own data within my own network, effectively protecting certain devices from other devices on the SAME network. Bottom line, I don't want a tech-savy teenager being able to harvest my banking username & password by using a WiFi 'sniffer' or other hacking tools?. What does AT&T (or others) offer for protection in scenarios like this? Are we talking about VPNs, something else?

@brockster  One of the easiest things you can do is point all of your IoT devices, at least those that are 2.4GHz (unless your router also has a 5GHz channel) to the Guest Network, which should automatically be assigned a separate address from your primary network. Then change the SSID to something other than Guest and use a different pw than what you use for your primary network.

As far as passwords go, use a password manager that will generate those 15-20 character pw's (like DByZ9aw%...... etc) that you can change whenever you need to. I use 1Password so all I have to do is remember the 1PW password and can let 1PW change generate new pw's whenever I need to and have it automatically update my other devices (phone, laptops, iPads, etc) automatically. There are other pw apps that do the same thing so you have choices. I have separate logins for my web-based router admin login, my router login (primary and re-named guest), and any app that needs a login.

I also use the security features offered by my router mfr. Obviously there are other options that you can do that are much more intensive but if you're not well versed in the more technical aspects of router security this is about the best, and easiest you can do. I wouldn't trust my home security to any ISP or the security features/apps they offer.

As far as routers go, I use my own Mesh WiFi system which is much better as far as configurability and reliability than AT&T's gateways. And, to be totally transparent, I don't use AT&T as my ISP.

You could also research on pfsense or opnsense firewall. It is mainly for defending against external attacks, bit could have rules for internal hosts also with proper networking and VLANs.

Those are good routers but take a really good understanding of networking to configure properly.

FWIW, the current gateway (modem/router) is a Pace, Model 5268ACFXN.

It was installed and configured by AT&T about 3-4 years ago. I've always suspected that when it came to internal security, that device has far more features than I am using. Time for me to do the research, and Thanks All for pointing me in the right direction.

I wouldn't assume that. You'll get much better security options and reliability with a third party mesh WiFi router (Netgear, Eero, Ubiquiti, Google, etc) than you'll get from the AT&T gateways.
