    First time posting but have referred to old threads in the past - thanks to all. I have Windows XP (updated w/ SP2) on a compaq laptop with a Broadcom G-card (updated driver). I have DSL through SBC on a Speedstream 5100b. Finally, tried to hook up a wireless network with a Belkin 54g wireless router - I opted to do this manually and followed the steps carefully. If the laptop is directly plugged into one of the four router ports, I get internet access (through Explorer) with no problem (only when I have the router configured for dynamic connection, interestingly). However, if I unplug it and go wireless, despite an excellent signal I cannot access the internet. Initially set for WPA, but also tried WEP - still unable to browse.
    By reading other threads I have some things to try (like maybe just restarting the laptop and hope for the best, disabling encryption, etc.) but is there a more logical approach to this? Thanks in advance!

    Hi, bucky98. Thanks for doing your "homework" (reading other threads) before posting.

    With wireless it is logical to start as simply as possible--no encryption, no speedboosting, etc. And restarting is really good to try whenever a problem doesn't make sense--often Windows can clean itself up.

    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:

    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?

    Thanks, I should have mentioned that I'll be trying this stuff when I actually get home. But I know that I set up the router to not accept pinging so I'm assuming I'll have to change that first as well. Also, do I 'ipconfig / all' and 'ping' wireless-ly? I don't want to assume anything, although things work fine when I'm plugged into the router.

    "... set up the router to not accept pinging .."

    That was probably on the WAN or internet side.

    "do I 'ipconfig / all' and 'ping' wireless-ly?"

    Yes. Of course, you could also do them when connected via ethernet to see the differences and similarities.

    I get replies when I ping the router wirelessly, but not to any websites.

    After shutting everydown and restarting modem, router, computer (waiting 2 min each), now I cannot ping the router wirelessly (despite it saying I'm connected). I can ping when it's wired. I double checked the IProuter to make sure I was pinging the right IP, too. Also, the wired connection is working with PPPoE whereas before it would only work with dynamic setting.

    Can you right click the icon on the task bar and bring up the status box? If so, are there any return packets showing? If not, click the support tab and try " repair."

    Well, you have me lost. How about starting at the begining this time.

    Is the Speedstream 5100b a router? If so, how do you have it configured? Show us an ipconfig /all for a PC connected directly to the Speedstream 5100b.

    When you connect the Belkin router, does the WAN (Internet) configuration match the above ipconfig for the PC connected to modem?

    And finally, show us an ipconfig /all for a PC connected by ethernet to the Belkin rouoter and for PC connected wirelessly.

    And the plot thickens ...! :)

    The first ipconfig is unusual; I've never seen a router provide an ipconfig with public IP, public Gateway, and then give itself as DNS servers. But obviously it works, so that's no problem.

    After you connect the Belkin to the Speedstream, does it's WAN configuration match the above ipconfig? No reason to think it might not match, just want you to take a look at it.

    I think your 3rd ipconfig is a duplicate of the 2nd, so we still need to see the critical ipconfig /all for the wireless connection.

    Thanks again for your help. This has become a matter of pride now that I've spent an entire day on it...anyway...
    "I've never seen a router provide..." - just to clarify, the first ipconfig is from PC to modem, not through the router

    "WAN configuration match..." - actually, they don't:
    Subnet mask = 255.255.255.255
    Wan IP = 69.210.144.143
    Default gateway = 69.210.159.254
    DNS Address = 206.141.193.55

    "3rd config is a duplicate of the 2nd" - I thought it was weird too, but that was done wirelessly. However, I just did it again and got the following:

    >ping 192.168.2.1

    Pinging 192.168.2.1 with 32 bytes of data:

    Destination host unreachable.
    Destination host unreachable.
    Destination host unreachable.
    Destination host unreachable.

    Ping statistics for 192.168.2.1:
    Packets: Sent = 4, Received = 0, Lost = 4 (100% loss),

    That WAN configuration looks more normal than the 1st ipconfig I commented upon.

    I thought the Speedstream 5100b is, or could be, a DSL modem/1-port router combo. Whatever, I don't think it's important for this problem.

    The last ipconfig shows that your wireless adapter asked for a Dhcp server and none was found; so Windows assigned an APIPA of 169.254.x.y.

    Make sure the Belkin's wireless signal is not encrypted (until we get it working). You didn't do any of that other junk like disable SSID broadcast or MAC address filtering, did you? If so, undo it. Change the SSID, if you haven't already, to something unique.

    On the laptop, are you using the adapter's utility or Windows' WZC to manage the connection? Do you "see" one or more networks when you 'view available networks'? Is one of them yours? What happens when you tell the utility to connect?

    Encryption is off. SSID is unique and is broadcasting. MAC filtering actually was enabled, now disabled. How about the firewall? Currently enabled. I'm using Windows to manage the connection. I do see several networks and one of them is mine. If I tell it to connect I get "limited of no connectivity". You can see packets sent but none received. Strong signal strenth, speed 54Mbps. Thanks.

    Eureka! It works. It was the MAC filtering. Dunce cap on, sitting in corner. I'm going to take a time out and then see if I can start enabling encryption and all that other good stuff again. Can't thank you enough for your help. Have a great weekend.

    Enable WPA encryption with a passphrase of 20+ letters AND numbers. The other stuff is not good, it's dumb. Anybody who can break WEP or break WPA with a weak passphrase can break that other stuff much quicker and easier. See http://blogs.zdnet.com/Ou/index.php?p=43
