All routers come with some degree of firewall capability.It usally will not say it because it is know by standard that routers can be configure to restrict incoming and outgoing information.Check the routers manual.There will be a section that will assist you in configuring your router to restrict traffic as needed.

To add to the other answers, a router is a hardware firewall at least, and is almost always better than a software firewall, like Zone Alarm or XP's built in one.
A router takes 1 public IP (visible to the whole Internet) and makes the Internet available to computers on a private network (invisible to the Internet). That's called NAT (Network Address Translation), and it's one of the best ways to maintain security from hackers on a consumer or business computer.
I've never heard of a network adapter having a firewall, but I've heard of the concept.
A properly configured software or hardware firewall should keep almost anyone (except a teenage male who downloads malware in the process of doing "cool" stuff) safe from hackers.

a router simply by the nature of the way it works is a firewall.
Want a simple test? take a system with no router, and install a firewall like Zone Alarm. It'll go off about every 5 minutes or so.
Then put a router on it.
See if it reports 1 violation over the next...oh...6 months.
Routers provide far supeior firewall tye protection than anything PC based (assuming the system is free of trojans etc to begin with).If you use internet explorer or Outlook or Outlook express though, you should probably also run a softwall like zone alarm.

Many routers do come with firewalls as a part of their firmware. And yes, it should say on the box if they do. I've never heard of a network adapter with a firewall on it, but I suppose it is possible.

Routers provide protection because hackers need to know the specific IP of your computer to violate it. Routers will broadcast a generic IP address which is of no use to them. I would still get a firewall just to be safe.

Yea it would. Check your router's manual.

many do, but I'd stick with PC based ones. There are plenty that are free.
