    Hello, I have been having this issue for 3 weeks now and I'm absolutely stumped. whats been happening is that my online applications such as yahoo messenger, mozilla and my online games such as Final fantasy 11 have been disconnecting every hr exactly. as soon as each application disconnects it reconnects automatically (except ffxi) and its good for another full hr. while this is happening my connection remains solid and doesn't disconnect. I have tried many things such as updating my drivers, scanning for viruses, unplugging my router and just testing my gateway, portforwarding, turning off windows firewall, and even calling my isp.

    my isp said that my SNR margin was 6/7 and one i plugged another phone cord into the jack it jumped to 12/17 which is acceptable from what I understand. even after that dramatic increase in connectivity I still dc from my applications every hr. Its quite frustrating since its only been happening for the past few weeks. Im starting to think it could be my gateway but growing more unlikely as it seems to like clockwork. They had me check all the filters on the phone lines and they are fine. So any ideas would be very much appreciated, im at the end of my rope as far as ideas.

    thank you for your time,

    ~blaze

    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).
    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.

    Check the WAN status page in the router and post a screen shot of it here. I'm particularly interested in the lease start/end times for the DHCP lease.


    To post a screen shot of the active window, hold the Alt key and press the PrtScn key. Open the Windows PAINT application and Paste the screen shot. You can then use PAINT to trim to suit, and save it as a JPG format file. To upload it to TSG, open the full reply window and use the Manage Attachments button to upload it here.

    ok i hope this is what you are looking for, there isn't really a WAN tab in my linksys router page. it seems that every time the clock hits 50 like 1:50, 2:50, 3:50 etc, my applications disconnect and reconnect every time... doesn't matter if i start it at lets say 1:30, it still disconnects at 1:50 and i will be good until 2:50. its really odd... even if i do not have the router plugged in this happens. i hope this screen shot helps.

    I don't have any knowledge of what could be going on, but your description makes it sound like the ISP is doing something on schedule--say, checking MAC address of the modem against their database for example--that is interrupting service. Unless, very unlikely, you have something scheduled on your PC for every hour on the 50 minute mark.

    If this has anything do to with the lease time it would mean the lease is for an hour (and expires) or for two hours ('cause it should be renewed at the half way mark). If you connect again directly to the modem you can check the lease time with an ipconfig /all.

    Or, if you have nothing connected (and powered on) to the modem for more than two hours a new lease would be started, presumably not at x:50.

    maybe i will have to put more pressure on my isp... this only started about 3 weeks ago and the weird thing is my connection doesn't actually disconnect, just what ever i am running that requires internet. i dont know all that much about networking so lease times are not familiar to me, i dont see why that would be enough to disconnect my applications. Would using ipconfig /all before the disconnect and after the disconnect help a little more if i posted them?

    *edit* seems to be no difference in before and after the dc. ill include the print outs anyway to look at, i hope some of this info is some help.

    Those ipconfigs were for a connection to the router. I thought we are suspecting disconnects before the router. Before and after ipconfig /all for a connection directly to the modem may be revealing. Please post them directly here for our ease of reading.

    I neglected to look up the specs on your "modem." It's a modem/router combo, so we still don't see the connection with the ISP with the above. Need to look at it's WAN status, if one is available, to see the lease time from the ISP. Sorry.
