As I am messing around online, I am suddenly getting numerous warnings about an IP conflict on my system. I've been told that this means that someone else is able to somehow use the same IP address on my wireless system, and the only other computer in the house is off. What would this mean, and is there a way to combat this?
I keep getting an IP conflict error

Umm.. Turn on security on your wireless router to prevent most (unless they have mad Wpa or Wep hacking skills) from connecting. Also, most routers can show you the MAC address of the systems that have/are connected to your network, so if there is more then your 2 computers on the list you can see if others have connected.
Any idea on how to do that sort? I use a linksys wireless B, I don't know the exact model number unfortunately.
Can you login to the linksys itself? That is what they are asking you to do. If you log into the linksys you can enable the security and enable passwords and such.
You can probably connect to your router by opening a browser window and in the address bar type 192.168.0.1. That might be the default IP of the linksys.

XP: Press Start, then run, type in "cmd" and press OK.
Vista or 7: Press start, type "cmd" into the search box and press return.
The black Command Prompt will open up. Type in "ipconfig" and press return. There should be a listing for Default Gateway, commonly it is 192.168.1.1, but if it is different take a note of it. Now go to your internet browser of choice and in the address bar enter the values for the default gateway. A login box should appear asking for a username and password. If you don't know the password for this leave the username field blank and enter "admin" for the password. If this doesn't work use "admin" for the username and the password. If this doesn't work and you don't know the password you will probably need to reset your router by holding down the reset button for ten seconds and then trying again.
Once you get into the router's webpage you should find some sort of link for security or wireless settings. Click that. If it says that your security options are off or set to none, you need to turn it on right away. Set it to WPA if there's an option for it, if not select WEP, and enter a password into the box. Remember that password, your computer is going to want you to enter it... right away, I would presume.
If you still get the ip address conflict, or your router already had security turned on, then check to see if your computer is set to obtain its ip address automatically.
XP: Start, Control Panel, Network Connections, right-click on the active connection and select properties. Select Internet Protocol (TCP/IP) and press the Properties button.
Vista: Start, Control Panel, Network and Sharing Center, Advanced Network Connections, right-click on the active connection and select properties. Select Internet Protocol Version 4 (TCP/IPv4) and press the Properties button.
7: Start, Control Panel, Network and Sharing Center, Change Adapter Settings, right-click on the active connection and select properties. Select Internet Protocol Version 4 (TCP/IPv4) and press the Properties button.
See if it is set to obtain the ip address automatically or if it is using an ip address entered into the boxes. If it is set to get an ip address automatically it should resolve any conflicts in the future, if not then report back and one of my helpful assistants will be able to help you.

I figured out my model number, in case that at all helps (I am not having much luck on the support site). BEFW11S4 (V4). I decided to risk it and change the password, so far everything's working (I did not change any of the selected settings, so I hope nothing else got screwed up when I hit apply). How do I check the list again, would it be the "DHCO Clients Table"? If it is, I checked that, and saw my computer listed and several others, one says server another has random characters and another is a name I do not recognize. There's only one other computer in the house at the moment and it is turned off, so technically, shouldn't my computer be the only one listed to be accessing it?
I can't seem to figure this out, all of the menus on the support site are just different enough so that the terminology and how to access what works differently, despite the fact I had to enter my damn model number just to be able to access the customer support area *sighs*. Would "WEP Key Settings" take care of this by any chance?
Simple solution.
a) make sure DHCP is enabled on the router (it's usually under the network settings
b) make sure your is set for assigned IP addresses.
This will ensure you don't get the IP address conflicts as each computer that connections will be automatically allocated it's own address.
And under no circumstances use WEP - it's broken like a hooker hymen.
if you're connecting wireless you want use at the very least WPA but preferable WPA2 with AES.
Setup this up under the wireless configuration on the router and it will prompt you for an encryption key - the longer the better. When you connect you'll be prompted for the key and until you enter it you won't have network conncetivity.
Oh and the DHCP table shows which IP addresses are allocated to which computer.

After a night of troubles, I ahd to reset the router because I frigged things up. How do you look at a list of people connected? That table I mentioned, it for some reason only shows one now, and it's definitely not mine.
What does it show?
Sometimes the router will just show the IP address and the MAC address it's associated with.
I can't remember what MAC stands for but it's unique indentifier for each network card and appears as combination of numbers & letters seperated by ether a - or a :
e.g A1:00:B5:FF:11:4E:BB
if you're connected to the access point what you're seeing is the connection from your computer but to make sure
open a command prompt on the computer
enter ipconfig /all | more (hit space to scroll down)
look for the line that says Physical Address and compared the numbers.
return to windows (type exit and hit enter)
Now make sure you've got encryption eneabled for the wireless - as I mentioned above you want to use WPA2 with AES (there maybe an option for WPA2 Enterprise which you don't want). If you've got the wireless enabled and you not using WPA at the least you're dancing naked in a full moon.
It shows a name "fountain" and then "Fountain itouch" none of the numbers are mine or my fathers, that's for sure. Before I began all of this, that table showed several names including mine (but I can't remember my fathers and his computer was on for some of it, he's connected by cable wire), and after I've done the firmware upgrade and a secure attempt (which I had to do a router reset as it didn't work properly), I had to reset the modem (that took two tries because I didn't hold the button long enough), the firmware upgrade held, then I made a change to the access web interface password and did a simple port opening, that's all I can recall that I've done. Since then, my information does not show up on the client table.
Oh, and I just got another ip conflict warning, even though the list doesn't show anything other then two items, and the ip's a different. Bah.

Well it sounds like some-one's found you access point wide open and have decided to connect.
So disconnect the router from the internet
change the SSID away from the default.
Lock it down with encryption with a strong password
change the IP address of the access point (for example the default might be 192.168.0.1 in which case go for make it 192.168.67.1.
Check that's updated the IP address range for the DHCP.
Make sure your computers are set for server assigned IP address and DNS entries.
check the computers connect and are able to get an ip address from the router
check they can ping the router
reconnect to the internet
If you don't think you can do this yourself - find some one who can get and get them to come out. Even if you have to pay the local computer store, it's going to be cheaper int he long than have a wide open access point that any tom dick or harry can connection which it sounds like you've got at the moment.
Just hope no-one's been looking at dodgy pictures or planning terrorist attacks via your router.
