    I meant that the whole apartment could be hardwired into one router, IE everyone in the building sharing the same internet connection. Thats where the apartment reference came from.

    It's very difficult to know without knowing his actual router and security configs. For instance, if he had a Linky WRT54G, plugged it in with the stock wireless security settings (none), DMZ'ed his pc for gaming or something and forgot, then he's as wide open as Paris Hilton :grin: And if that's the case, he definitely should check his rig thoroughly, 'cause it's got a nice target all over it. And then it would be as easy to bot it as taking candy from a baby!

    It would be also interesting to see, if when the pc's are showing on his HR20, if they also show up in the router's DHCP client table. But then again, if they half way know what they are doing, they could simply select a static LAN IP outside of the router's DHCP assignments and they will never show in the router's DHCP client table (I do this with my gaming server).

    Vikerex, to me it still sounds as if your network has been compromised. I would highly recommend scanning for nasties after you plug your security holes. It might surprise you what you find.

    I use MAC address filtering, and although it can be a PITA when I add new devices to my network, it gives me a little piece of mind.

    I can't add any more suggestions than what everyone else here posted, but it sounds to me like the router is acting as a WAP and neighbors are connected to your network, and your HR20 is seeing this.

    We definitely need to know your router brand, and the model would be helpful. Almost all routers allow you to see what devices are connected to it, and whether they are wireless or not, so you also need to log in to your router and see what it's reporting.

    Actually, to the best of my knowledge, all wireless routers come with wireless OFF by default...

    Actually, most wireless routers have wireless ON by default. And on without any security. Of course, this is limited to what I install, but includes LinSys, DLink, Buffalo, Vonage, Belkin and a few off brands. I've never actually seen a wireless router with wireless OFF by default, typically, you can plug them in and they just start working, having wireless off by default would cause users to make more calls into support.

    What can I say, all 4 routers I have purchased in the last few years were off by default, Linksys and Netgear models. Just going by what my experiences had been.

    I'm using a Linky WRT54G. Just plugging it in and leaving it at factory settings the wireless is on by default with no security settings on the wireless side. You either have to push the "Secure Easy Setup" button on the router, or set up something like WPA from within the GUI (which I did). But, on mine anyway, the wireless is on by default.

    Do you mean wireless is off, or wireless security is off? I thought you meant wireless functionality is off.

    Wireless was off by default. BTW, I never use those ridiculous setup disks that come with them. I had to turn the wireless on, and of course encryption, mac address filtering, etc...

    Intersting, by default dlink and buffalo stuff is on by default with no security. I rarely use linksys and didn't try wireless before configuring the last two linksys devices. But dlink and buffalo are on by default, take them out, plug them in and they work.

    Well, last night I redid my set up. Now all I can do is watch and see If it happens again. I am running a Motorola VT2442 router from Vonage. The computer and HR20 are hard wired to this. The router is then hard wired to a Motorola SB4200 Cable Modem. I tried to look at the "other" computers, but could not see any pictures or music. There were folders I did not recognize on the "other" computers. As far as I know it is a NAT router, and the firewall is on, I am also running Zone Alarm firewall program. If/when I see the "other" computers, I will have to see if they are listed in the router's DHCP client table.

    I also wish to say thanks to all of you who are trying to figure out this problem for me!!!

    Thanks again,
    Ted

    Yes, the Linksys comes with the wireless on and wireless security off by default.

    What program are you running on your computer for the media sharing? I saw on another thread where someone running twonky I think said that it sometimes would set up two effectively identical servers on his computer. Just something to look at.

    I've found the opposite to be true. I have the popular Linksys WRT54G and it happily serves up my nieces Wii and DS handhelds in its default configuration. Come to think of it, it also opened a channel to a friends Ubuntu laptop.

    From what I can tell you have nothing wireless. The ZA firewall should keep your pc okay. Check and see if the pc's appear again, and if they do, if they show up in your DHCP client table.

    Also, do you have a fax or anything else connected to the Vonage router? I'm not too familiar with the Vonage routers, but maybe it assigns a LAN IP to all your stuff, and this is what you're seeing? Just a thought...

    I have used two wireless routers, a Belkin and a Netgear (I returned the Belkin because it only had limited port forwarding capabiity). Both had wireless on and encryption off by default.

    If you set up encryption (WPA, WEP-128 or WPA-64, in decreasing order of security hardness), your HR20 should not see any computers not having the proper security key. Your game adapter or wireless ethernet adapter and computers all need to be set up for the same encryption, of course.

    A software firewall on your computer won't isolate the HR20 from other computers accessing via your router. My Netgear router has an optional "access control" setting which allows me to specify the MAC address of devices for I wish to allow access. MAC addresses are unique to each piece of networking hardware, so this is reasonably secure.

    My first cable modem [a long time ago] had a flaw in their controlling.
    If I went into my network and looked for other computers, I could find other computers in my [actual] neighborhood. Cable modems work off a node before they go to fiber.
    If someone else didn't have a firewall setup, I could go into their PC and copy files to mine. I couldn't leave a file [message to tell them they had a security problem], but after it was publicized the ISP fixed it.
