    Alright well recently, as in the last couple of days, I have been having problems with my internet. At random intervals of the day my computer will tell me that it is connected to the modem but the modem is not connected to the internet. However when I look over at the modem all of the lights are on and flashing like they should be. The DSL light is on and the Internet light is flashing to show that it's working. Furthermore if I go into the setup page for the modem using my browser the status page there also tells me that the DSL is connected and that the LAN is connected as well.

    This happens randomly and when it does I attempt to correct this myself by changing my static IP settings and DNS server settings. Eventually it does start working again but I don't know if it is because of something I actually fixed or by random luck. I hope you guys here can help me figure out this problem.

    Welcome to TSG.
    Do you receive any error msgs when this happens.?
    Operating system and level ?
    Any hardware /software changes ?
    Just for safety sake,I would run your antivirus/spyware progs to flush out any potential problems.

    Then,when you feel that you are having the problem.
    Let's see these pings.

    From a Johnwill post on the Networking Forum

    Try these simple tests.

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

    In the command prompt window that opens, type the following commands one at a time, followed by the Enter key:



    PING 206.190.60.37

    PING www.yahoo.com
    Right click in the command window and choose Select All, then hit Enter to copy the contents to the clipboard.
    Paste the results in a message here.

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

    Name of your ISP (Internet Service Provider).
    Make and exact model of the broadband modem.
    Make and exact model and hardware version of the router (if a separate unit).
    Make and exact model and hardware version of any other network equipment, like a repeater, a booster, hi-gain antenna, etc.
    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)
    Version and patch level of Windows on all affected machines, i.e. XP (Home or Pro), SP1-SP2-SP3, Vista (Home, Business, Ultimate), 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?
    • For wireless issues, 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 on separate lines, following each one with the Enter key:

    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.

    My modem is a Zyxel P660RT2 ADSL2+ modem. It is a wired modem and there are no routers in play. My ISP is Disel (UTK), there is a 100% chance you are not familiar with them because it is a russian firm and I am currently located in Russia lol. I use firefox as my browser and I have Windows Vista Home Premium Service Pack 1 installed. I am connected with an ethernet cable to the modem and there are no error messages invovled. All that happens is the network page tells me that the modem is not connected to the Internet and when I try to navigate to a web page it tells me the web page was not found.

    Here is the paste:

    That shows a working connection. We need to see it when it's not working.

    I hope this turns out something I can fix however I have a bad feeling that this might be out of my control.

    That confirms that your computer appears to still have a connection with the modem/router but that unit does not have internet access.

    Access the router part and check the WAN (Internet) status when it is working and when internet access has failed. Any difference? If so, what?

    When it is working the WAN status says that the DSL is up and downloading and uploading at a certain speed. When it is not working it still says the DSL is up and downloading and uploading at a certain speed. This also applies to the indicator lights on the modem itself. However right now I assume that this is actually the problem on the end of my ISP since this past day the internet was pretty good and only went out once and creating this interesting situation. However if there is something on my end that is causing this I would like you to inform me. Until then I leave this unsolved but if you can assure me that this has nothing to do with anything that I will be able to do then I'll change it to solved.

    Can't completely rule out some problem with the modem/router, but I agree that the cause probably lies with the ISP. You could try calling them to see if they admit to having some issues recently. If you do, you might want to call several times as some tech/customer support people are more reliable with this type question than others are.

    I wouldn't advise marking this Solved until and unless you get good uninterrupted service for 2 or 3 days running.

    Alright thanks. I'll make sure to come back and mark it solved if that does happen. Thank you for all your help.
