Possibly (probably) a dumb question...but here goes...
If you've got two PCs on two different floors that are sharing a broadband connection (via a wireless router), do they share the same internet history? Could I see their internet history on *my* PCs browser (and things like bandwidth usage etc)...and vice versa?

Each browser on each computer keeps its own history. Really, if you run multiple browsers (Firefox, Opera, IE) on the same computer each browser will keep track of its own activities and no more.
Now I suppose from the outside - the service provider, for instance - it all looks the same.

How do you view your bandwidth usage? That's usually an ISP function. If you have to visit a website to check your bandwidth then it's most likely the sum of the two (or more) computers sharing the connection. If it's a program that runs on your PC it's possible that the bandwidth total is only for your system.
Things are different on a satellite connection though. Satellites operate differently than DSL/cable. So my answer above might not be true for satellite broadband.

Yeah, I can login to my online account info on my ISPs website. They track total bandwidth usage.
Just didn't want the other computer to be able to access the history on my PC. Doesn't look like that'll be an issue.
Thanks for the replies.

That's slightly different from your original question.
You'd asked if they share the same history, and croy said - they do not.
Access is possible though. I suppose it depends on if the computers allow access to all of their files, to the other computer on the local network.
For example: Using Firefox, the history is kept in a file
named history.dat in the profiles directory.
If the other computer can access that directory, then it could copy that file.

Might there also be a possibility that the router itself is logging everything (or could be configured to do that)?

Hmm. There should be a way for me to find out if that's the case or not. As in, I can try to access their files. If I can't, then it's fine.
I don't see how it could happen, though. It's just a couple of computers in the same building. We aren't on a LAN or whatever. The wireless router is by my PC. That's the only connection between the two machines.
In fact, I don't even understand how the router works. I'm not very computer savvy. The router is plugged into a powerbar...and the other line is plugged into the back of my modem. Somehow they are able to get access just like that.

Keeping router logs typically requires a server. Routers send the data to the server, since the average router has no hard drive. Furthermore, routers log IP addresses, and maybe port numbers, so they aren't going to look like 'history' as defined by your web browser.

If someone is getting access "just like that" to your wireless router, it means you're running it with the encryption turned off, which is not a good idea. Even if you want these people on the other floor to be able to use your broadband connection, you don't want everybody else within range to be able to. Go into the router's web interface and follow the prompts to turn the WPA on. You'll need to pick a passphrase, and give it to whoever you want to be able to access the connection.

Geez. Shows how much I know.
I don't even know how to access the router. It doesn't "show up" on My Computer.
The router isn't mine, but it's connected to my PC. I didn't think anyone outside of the house could get access...since I'm not on wireless internet...but DSL. Confusing.

Time out . . .<ul style="list-style:none;padding:0px;margin:5px">
  • DSL is a type of broadband internet service delivered to your home over copper (telephone lines).

  • It connects to a special DSL modem which then connects by wire (either ethernet or, less likely, USB) to a computer OR to a router.

  • If you are using a router, it can be wired, or wireless, or both. (One wire connects back to the modem -- we are NOT counting that one.)

  • If you are wired to the router, there will be an ethernet cable connecting your computer to the router.

  • If you are operating wirelessly -- that is, you are NOT connected to the router with an ethernet cable, then you DO have a wireless internet/lan connection via your wireless router.

  • If you ARE using a wireless router, you SHOULD have security settings enabled. These prevent unauthorized use of your internet connection and outside access to your computer(s)

  • While most of us are constantly complaining that our wireless routers have very little range, their signals CAN be picked up as much as half a mile away under ideal conditions and with the proper equipment. This is WHY security is important.

    You access the router through your web browser. Usually, it's http://192.168.0.1 or http://192.168.1.1 The login/password, assuming it hasn't been set by the owner, is usually admin/admin or admin/.
    It would be a good idea to go to your router manufacturer's website and download the manual for the particular model you have.

    Thanks for the input guys. I'll try to process all this info.
    I tried accessing the router with those IPs...but nothing showed up.
    The router is an Apple AirPort Extreme (802.11g). I have a PC on Windows 2000 Professional. Not sure what computer the folks upstairs as using. Does anyone know if the base shown in the picture is the only piece of hardware? Or are there other parts as well?
    From what I can see, there is a large blue cord running from the router to one of the Local Ethernet plugs in my modem. The only other cord from the router is the power input or whatever that goes to my powerbar.
    So...it's not a true wireless connection, right? There's no way anyone outside of the home could "steal" any signal.
    It just seems "wireless", since I think the only real connection between my computer and theirs is the phone jack. We have two different numbers, but I'm assuming if they were to unplug from the wall upstairs, they'd instantly lose Internet access.
    Or something.
    :D

    The upstairs peoples' telephone jack (assuming it really is a telephone jack, and not a wired network jack) has nothing to do with your DSL connection.
    Does your modem have other cables plugged into the Local Ethernet ports, or just the one that goes to the AirPort?
    When you go to My Network Places and click on "View network connections," is there a wireless connection shown? What does it say under the "status" column?

    There are four jacks under Local Ethernet. 1,2,3,4. In 1 is a yellow cord that runs from the modem to the network port or whatever in the back of my computer. 2 is this new blue cord from the router. 3 and 4 are empty. So is the WAN jack. The only other cable being used is the one into the phone jack on the modem.
    The thing I'm trying to wrap my head around is...how else are they gaining access if not through the phone line?
    I tried My Network Places. Clicked on "Computers Near Me". Nothing.
    Also checked out Network and Dial-Up Connections and it looks the same as it always has.
    Type: LAN Status: Enabled
    VIA Rhine II Fast Ethernet Adapter.
    I wonder if they have the software that comes with the Apple AirPort Extreme router...and if THAT would allow them to display things like connections, IP info, history etc...

    OK: your computer has a wired connection to your modem (which has a built-in router/four port switch). The AirPort has a wired connection to your modem. The Airport is a router which provides both wired and wireless connectivity. If there is no cable leading from either your modem or the Airport, and running upstairs to your neighbors, then the only way that they are using your DSL is wirelessly, i.e., their computer is connecting to the AirPort via radio waves. They, or you, should ensure that the security features of the AirPort are enabled; otherwise, anyone within range who has a computer with wireless capability can also connect to the AirPort in your room and leech your bandwidth, and maybe attempt more malicious activities as well.

    Who has the DSL, you or the people upstairs?
    If the people upstairs have the DSL then their phone jack is very relevant. (DSL is provided through phone jacks.)
    It sounds to me like 007 is accessing the internet through his router which forwards packets wirelessly to the router upstairs. (It doesn't sound like he has DSL. His neighbors do.) I know it's possible to configure two or more wireless routers to expand a network but forget what the lingo is to describe that feature.

    The Airport, like most consumer-grade routers, has a logging ability built into the router. It doesn't keep a long history if enabled, although it does have the ability to write that history out to a text file -IF- logging and this write-to-log function are both enabled. By default, they are not.
    Easiest way to be sure the only history active is on your own computer is to log into the admin screen of the Airport router and ensure that the logging function is disabled. For that matter, you really REALLY should have changed your router's admin password at startup.
    Here's how to log into your router, if you don't know how to do this already:
    1) In Windows, Press Start, then Run. In the box that pops up, type in COMMAND and then press the OK key. This brings up a DOS command line box.
    2) Once in the DOS command line, type this in: ipconfig This will display your IP configuration settings for the Windows box.
    3) Look for a reading for "Default Gateway." This is the IP address of your Airport Router. Write this down (or just leave the DOS box open so you can see it). On many routers, this is something like 192.168.1.1 or similar.
    4) Launch a browser window...any browser will do.
    5) In the browser address, type in the address you saw for your Default Gateway. HTTP:// is optional here...usually not needed. Hit enter.
    6) You will likely be presented with a username/password alert box. If you haven't changed anything from default on your Airport, the username/password combo is usually Admin and password or nothing at all. Check here for a complete list of default username/password combo's.
    Once in, you are now inside the router's various setup routines. Dig around and look for "history logging" or "logging" to find out what's going on with yours. And while you are in there, change your Admin username/password combo so nobody else can sneak in and take over your wireless.

    Thanks for all this.
    I was able to get into the network info using your steps LubeNLuv. Didn't see anything about the router though. Just stuff about my modem with my ISPs logo. I'll check it out more closely when I have more time.
    I'm the one who has the DSL. I've had for over a year. Literally, the only change between now and last week was that the router was brought down here. It was plugged into the back of the modem in the Local Ethernet jack. That's all. I don't know what they did upstairs. They just came back after a couple of minutes and said they now had internet access. There was no prompt to change any sort of password or anything. I didn't have to do anything on my own computer for them to get access.
    There is no Apple Router type software installed on my PC. I'm wondering if they have it on their computer. I'll ask them about security.

    Based on your new comments....here's my guess.
    You have the DSL connection. It's yours. Your PC is hardwired into your ISP's DSL modem. They came down with an Airport Router and they plugged that into your DSL modem. They are now "broadcasting" your DSL connection (via sharing) to their PC upstairs and are connected wirelessly. Depending on security, either they are the only ones with access to your DSL line -OR- dozens of other people can now share your DSL bandwidth.
    This opens up some security concerns if it were me. But to your original question, they (upstairs peeps) shouldn't be able to access your PC's history. They may be able to access the DSL modem/routers history if it's kept, but I'm betting it isn't as it doesn't by default...you'd have to set it up to do just that. The Airport is just a broadcaster in this case.
    Your bigger concern is whether or not they have applied security to the Airport wireless router and if they are the only ones with access to your now-shared DSL connection. Because if they didn't, anyone else can surf using your IP address. They access kiddie porn sites? Guess what....it will show up as a hit on that web site attached to YOUR IP address registered with your DSL provider. So make sure you trust them before you let them loose like this. Even if it's secured with a username/password, they could give that out to others and you'd still lose control.
    Safest bet is that you take over admin access to the Airport, assign it your own username/password and you control access via MAC addresses. Then only those people you trust and have granted access can surf using your DSL line.
    But I'm a paranoid MOFO.....YMMV of course.

    I can give my NIC your MAC address, so that by itself isn't a foolproof method of controlling access. If you aren't using an encrypted link, I can sniff your username/password, too. However, MAC access control will deter the casual hijacker next door who may accidently discover a 'free' internet connection.

    My wireless Router DOES keep a record of all web history from all computers as a default setting and can be changed or single records can be deleted from the admin access by browser or manual reset. It must have some kind of storage. I assumed this to be common, but I don't know.

    Exactly Hardware....MAC addresses aren't fool proof....nothing is really with consumer-grade routers. But it's "good enough" unless 007 is under serious hack attacks.
    Some other no-cost, low-effort security measures:
    1) Don't broadcast your router's ID.
    2) Enable WEP or other password encryption, and pick a difficult password.
    3) Turn on the logging yourself...and monitor it. And if you see Billy Bob upstairs is surfing "porn4pedofiles.com," report the guy to the cops.
    Safest bet is to not share your DSL connection at all...but it sounds like he was open to this in the first place.
    BTW, somewhat distantly related....I just saw that one of the RIAA cases ended in a judgement for the defense. The woman claimed her WiFi wasn't password protected and, therefore, she couldn't legally be held accountable for activity on her IP address. I think the better answer is to not do things that will get you in trouble in the first place.
    Oh and smartass comment of the day.....HARDWARE QUOTED MY POST WHICH WAS RIGHT ABOVE HIS OWN!!!! WOOT! I'm going POSTAL with quotes now!

    This seems the most likely scenario. I went back into the network setting by entering the default gateway IP...still can't see any router listed or find anything about LOGGING. Since the router is down here with me, I doubt the people upstairs could access any logs anyway. All this stuff about MAC addresses seems too advanced for me. I'll ask them if they know if the signal is protected or not. Then I'll go from there. Appreciate the help guys.

    You're not accessing the internet through the Airport router. I doubt your PC is configured on the same LAN. You won't be able to access it.
    I was thrown by the fact that nothing is plugged into the WAN port on the router. The folks upstairs essentially setup their own private wireless network using your DSL modem as a gateway.

    Oh. Right.
    So maybe there's nothing to worry about then? As in, I'm not using the router for MY access. Thus, it isn't logging my activity?

    The DSL account is yours, so you are still responsible for its security. If there are no security measures in place on the airport router, it is possible for others to steal bandwidth and do any number of legal or illegal things using your DSL account as their conduit.
    I hate to ask the obvious, but why are you supplying free internet access for a neighbor? Or, alternately, why are you allowing a neighbor to use your internet access without YOU having full control over its security and their access to your network?
    Then again, maybe it's none of my business....

    We're sharing the cost. I didn't look into security originally because I didn't know the signal could be stolen. I only thought that could happen on a "true" wireless connection.

    Hehe. That's the thing though. It's not WiFi. This is all so complex to me.
    They are girls though, yes.
    In addition to this desktop PC with DSL, I do have a laptop with a WiFi card. I could always try and see if there are any WiFi signals in my area (ie. my own) and then try to use it.

    Wireless router = WiFi....that's what an Airport Extreme is that it sounds like they/you plugged into your DSL modem to allow them access.
    But your idea is good actually....put your laptop into DHCP mode so that it automatically assigns it an IP and then see if it can "see" the Airport wireless. If you get an IP address, it's open for anyone else to use as well.
    BTW -IF- you do get a signal and can access the 'net, use the method I gave above, but this time on your laptop. That will let you get into the Airport configuration/setup routines.
    And I _KNEW_ there had to be pheromones involved somewhere in this plot.
