No, a router, whether or not it has wireless capabilities, should have a firewall, so that part should be fine. With that wireless, you'll want to make sure of these things, though:
[ol][li]If you are not using wireless currently, then the wireless capability needs to be disabled.[/li]
[li]Assuming you
are using wireless, the SSID should not be broadcast.[/li]
[li]Next step is that any modern wireless hardware should support WPA2 encryption. You need to have that setup so that no one is able to see/read what is being sent between your wireless client(s), aka laptop, pc, Wii, PSP, etc and your router.[/li]
[li]If you want to really ensure your wireless network, you should turn on Mac address filtering, probably under your security tab of your router settings.[/li]
[/ol]
If you are unsure as to how to log into your router, this would probably be a good time to learn how, and get logged in.
First, the easiest way to find out your IP Address of your router is to open a command prompt:
[ol][li]Start Menu[/li]
[li]Run[/li]
[li]Type
cmd[/li]
[li]Press <Enter>[/li]
[li]Next, on the black screen, type
ipconfig[/li]
[li]Press <Enter>[/li]
[li]The
Default Gateway address is/should be the IP address of your router.[/li]
[li]Keep that window where you can see it, or either write down the Default Gateway address. It will be something like 192.168.0.1 or 192.168.1.0 or something along those lines.[/li]
[li]Open up a copy of Internet Explorer - or whatever your favorite web browser is (Firefox, AOL Browser, Google Chrome, Apple Safari, etc[/li]
[li]Make sure any operation(s) has/have ceased there - it finished bringing up your home page, for instance.[/li]
[li]Type the Default Gateway address into the address bar, and press <Enter>.[/li]
[li]If you or no one else ever set a password for your router, then it will be one of the defaults, based on manufacturer. Here are a few from memory:
[ul][li]D-Link = Login:
admin, Password:
<Blank>[/li]
[li]Linksys = Login:
<Blank> Password:
admin[/li]
[li]Netgear (Most of them) = Login:
admin Password:
password[/li]
[li]US Robotics - well, the one I've messed with just let you strait in the first time, prompting you to set up your password.[/li][/ul]Whatever the case may be, you can find that information in your user manual or on the manufacturer's website.[/li]
[li]Once in your router settings, you NEED to set a password for your router, so that no one can easily get into your router and change/monitor your settings, history, etc.[/li]
[li]Once that part is finished, then you can make sure your wireless is secure, as listed above.[/li]
[li]One word of caution: the more secure your setup, the more of a headache it will be to maintain. For instance, if you use MAC Address filtering, then anytime you add a new device (friend brings laptop over, or you get a new wireless gaming system, etc), you will have to add their MAC address to the allowed list. You
can typically just go into the router settings, and say "allow currently connected", and that will usually do it, assuming the new device is already trying to connect to the router. But it'd be best to make sure there are no strange MAC addresses showing up before just allowing currently connected.[/li][/ol]
Oh, and don't tell me that you have FIOS. That's just gonna make me mad/jealous.
