    OK, I'm going to let everyone know that I'm not a computer guru. I can manage. Anyways, here's my problem.

    I've recently moved into an apartment complex that uses Hotwire Communications. My router is a LinkSys WRT54GS wireless router and my modem is a Zoon ADSL modem. I've talked to a friend who lived in a similar complex and he had a similar issue. He said that his problem was that his ISP used a DDNS, and not the static one (like my previous provider COMCAST).

    The problem seems to be me losing my connection. I'll either be playing a game or surfing the web when all of a sudden, the internet stops working. I've tried to look into setting up DDNS and signed up with DynDNS, but that's as far as I've gotten. All help is appreciated, and my current setup is Modem->PC (Not Modem->Router->PC)

    Thanks.

    OK, I think I may have figured this out. I mean, it's working now. I just registered a domain name on DynDNS and used that as my address for the DDNS option on the router setup. Is this the correct thing to do? Thanks.

    OK, that worked for about 5 minutes. Then it crapped out again. Windows vista said there was some problem with the DNS. I'm not sure how to fix this but any help would be appreciated.

    Here's what ipconfig/all says when I'm in the modm-> Router-> Computer mode (the modem-PC mode seems to work without problems):

    Now I just want to make sure you guys understand the situation. This is working right now (after restart of modem/router/comp). But the problem I've been facing is that all of a sudden it will stop working. Internet just poofs away... and later on it comes back (sometimes). And this is after cloning the mac address of the router to the same as the PC (I had an issue with this router and a cable modem before and had to do this). I've also setup the DDNS as explained above. I just used the DynDNS.org services. P

    As I was trying to post this, the internet decided to stop again. Here is what ipconfig/all had to say about it:

    I don’t see any differences here, so I’m not sure what the problem is….

    Using DynDNS is a way to make it possible for others (or yourself if away from home) to find you by a name instead of having to know the IP, which can change from time to time. It will not affect your maintaining a connection.

    Is that "DNS Servers . . . . . . . . . . . : 10.0.0.2" being assigned by your router or do you have it set in the TCP/IP properties? If the latter, I suggest you change it to 'obtain DNS auto.' If the former, then I assume that your Zoon ADSL modem is actually a modem/router combo with LAN address 10.0.0.2. Am I right?

    Do you get the disconnects when you take the Linksys router out of the picture? If not, then look for a firmware upgrade for the router. Then reset it to factory default settings and reconfigure it.

    There should be no reason that your IP address changes during an active connection. If that is happening, you have either equipment or ISP issues.

    Please supply the following info, exact make and models of the equipment please.

    What country are you located in.
    Name of your ISP (Internet Service Provider).
    What is the expected Upstream/Downstream speed for your ISP Connection?
    Make and exact model of the broadband modem.
    Make and exact model and hardware version of the router (if a separate unit).
    Model numbers can usually be obtained from the label on the device.
    Connection type, wired or wireless.
    If wireless, encryption used, (none, WEP, WPA, or WPA2)
    Make and model of your computer.
    Version and patch level of Windows on all affected machines, i.e. XP-Home (or XP-Pro), SP1-SP2, Vista, etc.
    The Internet Browser in use, IE, Firefox, Opera, etc.




    Please give an exact description of your problem symptoms, including the exact text of any error messages.

    If you're using a wireless connection, have you tried a direct connection with a cable to see if that changes the symptoms? Have you disabled all encryption on the router to see if you can connect that way? Have you connected directly to the broadband modem to see if this is a router or modem/ISP issue?

    If there are other computers on the same network, are they experiencing the same issue, or do they function normally?




    On any affected computer, I'd also like to see this:

    Hold the Windows key and press R, then type CMD (COMMAND for W98/WME) to open a command prompt:

    Type the following commands:

    PING 206.190.60.37

    PING yahoo.com

    NBTSTAT -n

    IPCONFIG /ALL

    Right click in the command window and choose Select All, then hit Enter.
    Paste the results in a message here.

    If you are on a machine with no network connection, use a floppy, USB disk, or a CD-RW disk to transfer a text file with the information to allow pasting it here.

    I do not get the disconnects when I take the lynksys router out of the picture. It definitely seems to be a router issue. I lose the connection with both a wireless and a non-wireless connection with two PC's. Also, the 10.0.0.2 may be assigned by my router (at least I did not choose that). I'm not sure how to set it to obtain DNS auto. Now I'm going to look into everything the previous post asked for....

    Oh, and the *Zoom modem is not a modem/router combo.

    To answer your easier questions, I see the same symptoms (randomly losing my internet connection) while using a direct or wireless connection to my ROUTER. When using a direct connection to the modem, I see NO PROBLEMS! Other computer are seeing the same problem. I'm not actually sure that my IP is changing. I talked with someone else who lived in a similar community who had a similar problem and he said that he made some change because of DDNS and it worked. I wasn't sure if that was the actual problem though.

    Now I will work on getting all of the other information together.

    What country are you located in. - USA
    Name of your ISP (Internet Service Provider). Hotwire Communications (DSL)
    What is the expected Upstream/Downstream speed for your ISP Connection? I'm not sure about the up speed, but the down is ~6MB
    Make and exact model of the broadband modem. Zoom ADSL Modem Series 1064 Model 5660A
    Make and exact model and hardware version of the router (if a separate unit). Lynksys Wireless-G Router WRT54GS v. 5
    Model numbers can usually be obtained from the label on the device.
    Connection type, wired or wireless. This computer is wired, but I can also do a check with wireless if need be
    If wireless, encryption used, (none, WEP, WPA, or WPA2) Encryption is WPA Personal
    Make and model of your computer. My computer is home grown, but again, I can give specs if needed.
    Version and patch level of Windows on all affected machines, i.e. XP-Home (or XP-Pro), SP1-SP2, Vista, etc. XP Pro SP2
    The Internet Browser in use, IE, Firefox, Opera, etc. IE and Firefox. Both don't work.


    I will run the ipconfig after I return (my girlfriend is making me leave now).... Thanks for your help.

    Now this is in the modem->router->PC setup. It is currently working. I will try all of these again when I lose the connection.

    OK, so about 2 seconds later, the same exact setup would not work (modem->router->PC). I made no changes. Here are the same commands from CMD:

    On a side note, I’ve found an option in the advanced routing tab of my routers config page this:

    Operating Mode : Routing
    Dynamic Routing : RIP : Disabled

    I can set this to LAN and Wireless, WAN, or Both. Is this what you were talking about with the automatically detect DNS?

    I was talking about obtaining DNS auto on your PC, but with that truckload of data above I'm no longer concerned about that.

    The last ipconfig /all indicates, FWIW, that your Zoom is a modem/router combo with LAN address 10.0.0.2, so that's where that address is coming from.

    What all that information you've given boils down to, I think, is that the Linksys router is losing its connection to the Zoom, and the problem is the Linksys.

    Two things to try to fix this are a firmware upgrade and then a reset to factory default settings and reconfigure it.

    Good job of putting together all that information for us! :)
