    I have a Linksys Wireless-G Broadband Router at my computer and a Linksys Wireless-G 2.4 ghz USB Adapter connected to my wife's computer (both Dell Dimensions) which is in an adjacent room. We're both using WinXP Home and we access the 'net via Comcast Cable.

    Today, when my wife tried to go online, the following window appeared: "Verizon Online- Denial of Service" at the URL "http://noaccess.verizon.net/noaccess/index.html".

    We have never used Verizon as an ISP. I think it was the default service on the computer when we bought it but we've always connected through Comcast.

    I did a "release & renew" of the IP address and the network icon shows we're connected with good signal strength. It just seems her computer has lost the Comcast connection. I even tried installing my original Comcast Installation disk on her PC but the Wizard is unable to find an Internet connection.

    I'm at a loss and would appreciate any assistance.

    Do you have an Anti-Virus running or a firewall by chance? If so, disable them, and try that.

    If you have encryption enabled, try w/o encryption until you get a successful session.

    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 (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?
