    Hello again tech guys,

    I am running a Dell Inpiron E1505, with an Intel(r) PROSet/Wireless built in card. I have connected with tons of networks before. I am currently out of town for a little while and am trying to connect to a network that is public (not password protected). I can easily connect to the network with excellent signal. I then go to Internet Explorer to start browsing and am unable to connect to any site. Whats my problem???

    Try to narrow down the problem with the following. Substitute "public network" for "router."

    First determine if the problem PC is really communicating with the router when it claims to be connected.

    To open a Command Window: Start - Run – cmd (command in 98SE) - OK

    To determine a computer's IP address and router's IP address: open a Command Window and type
    ipconfig /all

    The "Gateway" is the router's IP address.

    Now for some troubleshooting. Following is how to use ping to test for communication with your router, the internet, and the internet with symbolic name.

    1. On the PC open a Command window and type
    ping IProuter (where IProuter is the IP address of the router)

    Do you get Replies, or do you get packets lost?

    IF you got replies,
    2. ping 66.94.234.13 (or any other internet address you know)

    Do you get Replies, or do you get packets lost?

    If you got replies,
    3. ping www.yahoo.com (or any other internet name)

    Do you get Replies, or do you get packets lost?

    The default gateway IP address is 192.168.0.1

    When pinging 192.168.0.1 I recieved 0 lost packets, though when I pinged 66.94.234.13 I lost 100% of the packets sent. Needless to say yahoo could not be found.

    where from here?

    Those integrated Intel wireless adapters tend to be temperamental, so you could check Dell's website for a driver/utility update. And if you are using Windows XP's WZC, try using Intel's utility instead.

    Otherwise all I can think of is to make sure that you are connecting to the intended network (and not a neighbors accidentally) and then talk with a representative of that network.

    You clearly received an IP configuration from their Dhcp server but cannot ping an internet address, so it seems that they have a problem accessing the internet.

    Please keep us updated.

    Make sure you have a valid IP address for your internal network.

    Do other wireless devices get to the Internet?

    If they do, your wireless station may not be handing out a working IP address to your problem computer.

    If the wireless device only forwards an IP address from another DHCP server/router, then that server/router may not be handing out more IP's.

    This kind of problem is already an issue for most people. The reason for this maybe is that you RTS threshold and Fragmentation threshold on the router maybe too high.

    The problem is that you could not change it because the router is not yours. Power cycling will work, but definitely they would not reboot their router just for the sake of getting you connected.

    These things happen. And as i always say, blame the technology. Cheers!!
