From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

If you are only at home you don't need it because the router already has a firewall. But if you're is using public WiFi definitely use it.
It depends on how much do you trust your router.
Some home routers have poor security: unfrequent updates, http (not https) web consoles, single factor authentication (password only, without username for instance).
Enabling your firewall is the bare minimum, costs nothing and it's a good security practice.
Your router and every single device connected to your local network.
Sure that is true but if you're getting it from the ISP and it's that bad, you need to change ISP.
Plus, ALWAYS get into the router and set a new password. Always. And go over all the settings to be sure. As you say, a shit ISP may have lax security.
Changing an ISP is very rarely an option. That's why they pull the shit to begin with.
You should bring your own hardware wherever possible. I'd never trust my local network to the ISP.
Not to mention, a lot of ISPs still provide you with shit hardware, so by just purchasing an actually somewhat decent router you may even notice a performance improvement on your network as well.
You say that like its easy. It usually isn't.
It usually isn't too hard to insert your own router into your network setup. You might have to battle with ISP support a bit though, but a ton support either Bridge Mode or IP Passthrough.
I'm now sure how is is in your country but where I live we don't have a contract with the ISP. We just pay monthly and at any time we can cancel. But if you have a contract, then yes you'll need your own router ideally
In my country all ISP routers suck hard. I can change ISP but it doesnt help at all. You have to be lucky to get a working router it seems. We can get service with no contract with extra €, but you still have to use their router that doesnt support bridge mode. Im not even talking about routers security
