Connection to Wireless Router

Discussion in 'Wireless Networking' started by =?Utf-8?B?TGluZGE=?=, May 22, 2007.

  1. It says that my laptop is connected to the wireless network, but when I go
    onto the internet, it does not allow me to and says "server cannot be found".
    When I click repair for the connection, it only works sometimes and if it
    does work, I am still not able to go on the Interent and even the AIM
    service. My router works and it says that I have a strong connection.
    Sometimes, it seems like the wireless network forgets the IP address and asks
    for the WPA key code. What should I do to be able to get on the Internet,
    AIM, and AOL? Does Firewall have anything to do with it?

    P.S. What is a Subnet mask?

    You may not actually be communicating with your router, notwithstanding
    the "strong connection" indication.

    Is this your own wireless network, and do you have physical access to
    the router? If so, try connecting the laptop to the router using an
    Ethernet cable. Can you connect to the Internet now?

    Has this laptop EVER successfully connected (been able to surf the
    Internet) through this wireless network? If so, what changed?

    Are you sure that you are always connecting to the same wireless network
    (i.e., is the network name (SSID) unique)?

    What IP address is "forgotten"? What is the IP address of your laptop
    when you think it is connected to the router? A subnet mask is used in
    combination with an IP address to break up a larger network into smaller
    "sub-networks." In the typical home network, the IP address will be in
    the range 192.168.0.1 through 192.168.0.254 (192.168.0.255 may be
    reserved) with a subnet mask of 255.255.255.0. This has only one
    "sub-network" with the possibility of 254 computers. See
