    Honestly, I have no idea what I'm doing nor do I have any idea what so ever as to what I'm talking about, so please, if you would, bear with me.

    Recently my Linksys wireless-G 2.4 GHz on one of my old XP Dell's decided to break connection from the Actiontec GT701-WG router that is connected to a newer Dell. No big deal, Quest DSL fails on me from time to time. . . I attempt to reconnect and after a long while it tells me that my session has timed out and that the solution is to refresh the IP

    I pull up the command prompt window, "ipconfig /release" followed by "ipconfig /renew", nothing happens. After a while the command prompt window says "unable to contact your DHCP server. Request has timed out"

    I know that the router is broadcasting a legit signal because my laptop with an internal card picks it up just fine.

    My questions:
    What is a DHCP server and why can't I contact it?
    Should I try to use the command prompt "technique" on the computer hooked up to the router (it would only make sense ...)?
    Any simple solutions to my problem?

    Anything I left out that could be the key to getting me out of this jam?

    Thanks

    DHCP is what your computer uses to get a valid IP so you can connect to the internet. Now your laptop that picks up the signal, does it work ok? What device are you trying to connect with, laptop, desktop? Do you know if you setup wireless encryption?

    Try unplugging the actiontec, waiting 60 seconds and replugging. Both computers should find back the network within a minute after the router has been replugged.

    If this happens often (actiontec freezing and needing a reboot), I would guess that you are using p2p programs (most probably bittorrent) and that the router is overwhelmed by the amount of connection this uses. When overwhelmed, no new connection can be established, hence blocking the router until old connections expire.

    BTW, DHCP is a protocol that distributes IP addresses automatically to the devices connected to a network. The server is the one distributing the addresses. If your computer cannot contact the DHCP server (usually the router), it cannot get an address and cannot participate in the network.
