    Dear Readers,

    For the past month... For some strange reason my Internet connection dies out on me...

    I mean... My comptuer is supposedly the 'Host' as I am using SBC Yahoo DSL with a DI-604 Router... and so then I assume my Computer is the Host while my Sisters/ is just another Computer sharing the connection... Yet... For some reason every now and then (No pattern/ just random timing) MY computer will die and lose connection/ when I try to repair the Connection it cannot renew my IP Address. Also the Disconnects last from a range of a minute to 5 minutes... Also I tried switching the Ethernet Cables and that didn't do anything, so I actualyl went out to buy a new one from GeekSquad and THOUGHT that fixed the problem on the first day, but the next day bam the problem returned...

    Whenever my Connection is dropped... My Sisters is still active and runs normally.. So I am not sure if it is My computer or the Router that is causing the problem.

    I am not sure if I have provided enough information to get me anywhere, but if anyone can help me out that would be greatly appreciated.. And if you need more information do ask, thank you.

    Does your sisters computer have the same problem at different times or does it work ok allt he time?

    Do you have a third party personal firewall installed?

    What OS?

    Assuming XP, control panel->administrative tools->event viewer->system
    any network related error at the times of the itnernet not working?

    uhhhmmm...have you looked into your router's documentation?
    may be a clue in there
    I know nada about your router so can't really say what it may be
    now if you were on a Belkin router I might have had a clue
    (I think I'm the only one in here that has a Belkin )

    Ok as far as answering questions:
    @zaphodiv: My Sisters computer works 24/7 and has no problems...., I do have a Third Party Personal Firewall (BitDefender Pro 9), OS: WinXP Pro

    Well for the Internet thingy.. When it does 'disconnect' under my NetWorks.. The Gateway(Router) connection disappears and only my 'LocalAreaConnection' Remains.. But when I try to repair I get:"Your computer was not able to renew its address from the network (from the DHCP Server) for the Network Card with network address 000FEAFB2CA2. The following error occurred:
    The semaphore timeout period has expired. . Your computer will continue to try and obtain an address on its own from the network address (DHCP) server."(That is from that Event Log)


    @fkdup74: Let me post a LONG log as I not really sure how to 'read' it:

    From that log the router is receiving the requesst the renew the ip address.
    The most likly explation is the computer is not correctly processing the reply.

    I'm not familiar with bitdefender but I'v heard of personal firewall software causing DHCP renewals to fail.

    As a workaround try giving your computer a static address. You need to
    set the ip address, subnet mask and the dns server(s). Open a command prompt
    and type ipconfig /all to get the info.

    I think the problem is with your firewall.

    Btw with a router there isn't a 'host' or 'shared'. All computers connected to the router have the same status.

    @zaphodiv: I'll try that methood after this other one another forum suggested.. So I willupdate you on that if that method doesn't work.

    @Virtualbody1234: Firewall.. I am currently using BitDefender Pro 9's FireWall and the only FireWall setting I have enabled is the Programs.. ANd I dnot see anything on the list that is Internet Related so dunnos...

    ANd bleh yeah sorry about that Host/Shared thing forgot that the Router does serve as the Host.


    Edit: @zaphodiv: Ok the other method didnt work so I tried yours... And is the IP Address + the DNS Address supposed to be the same? Because on my config /all it shows as the same.. Only different is on the ip address it ends with .100 and the DNS ends with .1

    ^This seemed to have made it so that I can barely visit any websites... So I am reverting back to the Dynamic IP rather than Static to test out another method.^


    Uh OH... checked my Router Logs I gettinga lot of:

    No.

    Because on my config /all it shows as the same.. Only different is on the ip address it ends with .100 and the DNS ends wih .1
    So the addresses are the same except that they are different?
    I'm not quite sure what is going on in your brain there.
    Do you think bears and dogs are the same because they are both
    brown, furry and have four legs?

    Get the ip address, netmask and default gateway setting from ipconfig /all
    and enter them into controlpanel->local are network->propertys->tcp/ip->propertys->use the following ip address

    Type in the addresses _exactly_ as shown by netstat. Do not use some different address that looks a bit like that one you are supposed to be using

    IF it dosn't work then post _exactly_ what you did including the exact output of ipconfig and the exact addresses you used.

    Well I accidently changed my router settings so that MY computer is now udner the Static DHCP Client List and then my Sisters computer changed to 'Unknown' as the name now... And things seemt o be working ok.. except for the fact that when i do anything online it sort of 'lags' a bit before processing the data.

    And for your question.. I just mean that the IP's given like it would be 192.168.0.100 and another would be 192.168.0.1, is there really a difference in that? =X

    Edit; Ok i did as you told me to and things seem to be working ok.. I mean... should I switch my Computer Name/Information back to the Dynamic IP DCHS Client List?

    (Also how does one find out the MAC Address?)

    Duh, does 100 = 1? Of course there's a difference. What's your house number? Is it the same as the people at the other end of the street? Tip: don't get a job as a postman.

    Look at the physical address.
