    Cannot use internet but connection is good
    Hi, I read a lot of questions with the same problem but I can't figure it out.
    I have a router with wireless and cable connection. The cable (local area connection) works fine (100Mbps), but when I try to enable wireless does not work. It says "limmited or no connection" if I don't put an IP, and it says "excelent connection (54Mbps)" if I put an IP address.
    There was a MAC using the same network and wireless, while I had to connect the cable. The same computer (laptop Inspiron 6000) always used wireless, and it works in other networks but mine.
    I did a tracing and this is the result:

    1 5 ms 6 ms 5 ms 10.40.0.1
    2 18 ms 7 ms 18 ms ip-22.net-80-236-6.asnieres.rev.numericable.fr [

    8 120 ms 101 ms 105 ms yo-in-f147.google.com [64.233.169.147]

    Trace complete.

    Anyone can help?

    If it works just fine when you provide an IP address but doesn't when you don't, then it sounds like you have a problem with DHCP.

    Go to the command line and type ipconfig /all. Post the results here both with an IP address provided and without. I need to see what it's doing.

    Probably DHCP server turned off on the router, go to http://192.168.1.1 and check it out

    It was off and I changed, but still does not work.

    Is your wireless access point built into your router or is it a separate device? If it is a separate device, plug it in to one of the available LAN ports in your router. If it is, change it to a different port. It is possible to assign a LAN port to an Internet address. If this has been done in your router, you probably want to change this.

    In section 1, you are showing the MS assigned IP address meaning that an address could not be obtained from a DHCP server.

    In section 2, you assigned an Internet IP address and not one from your router. Why is that? Did you connect your computer directly to the modem? If this is connected to your router, then you should assign an IP address similar to the one in section 3 except outside of the DHCP range. Typically, the DHCP range is 192.168.1.100 to 192.168.1.150 in a default router setup. So using something like 192.168.1.80 would be fine. You must use the same subnet mask and gateway address as the DHCP assigned addresses.

    In section 3, you obtained a proper DHCP address from your router.

    Well, I'm actually correcting what I said, try the following as your IP configuration:

    IP Address: 192.168.0.90
    Subnet Mask: 255.255.255.0
    Default Gateway: 192.168.0.1

    DNS Primary: 192.168.0.1
    DNS Secondary: 82.216.111.124

    The reason you couldn't connect to the Internet when you provided the IP address previously is that your router is configured to work off a private network, with your public IP address only being used on the interface leading to your modem. If you try to assign that directly to your laptop, it's not going to connect properly. Give that a try, also, if you later want to use DHCP, you might try searching the Internet for a file named dhcpd.dll and replacing the copy of it currently on your computer.

    wow, you lost me... well there is only one device: router wireless NETGEAR connected to the cable service. I can use internet connecting the LAN (computer-router). Remember that other computer was able to connect wireless, so the router is working.

    Now, when I change the setting as TWILCOX said, nothing changes, in fact the little computer icon on the bottom right of the computer (quick launch) that represents wireless does not blink, bu maybe that's normal cause the one representing LAN does not blink eighter.

    %&^(!#%)(&!! What should I do?

    What is the model of the NetGear device? I would like to look it up to see what it is capable of.

    Mmm... maybe... would be CBVG834G?? Says NETGEAR Cable Voice Gateway.

    Wow. Three bonded connections. That can offer some really high bandwidth rates. I'm jealous. Your router has (1) WAN connection, (4) LAN connections and (2) VoIP connections.

    To start with a simple configuration would be best and then go secure once you have it all working.

    Based on what you have posted previously, verify the following settings:
    DHCP Server is enabled.
    The Scope would be something like this: 192.168.0.100 to 192.168.0.150
    The Subnet Mask would be 255.255.255.0
    The Router (gateway) address would be 192.168.0.1
    The primary and secondary DNS Servers would be any two of the following: 82.216.111.124
    82.216.111.125
    82.216.111.121
    82.216.111.122

    Verify that your PC's Local Area Connections TCP/IP configuration are set to obtain an IP Address using DHCP. When connecting a PC to one of the (4) LAN port connections with a Cat 5e or Cat 6 Ethernet straight passthrough cable, you should be able to go to a command prompt and type IPCONFIG /ALL and get the same information as you saw in section (3) above:

    IP Address... 192.168.0.101
    Subnet Mask... 255.255.255.0
    Gateway... 192.168.0.1
    DHCP Server... 192.168.0.1
    DNS Server... 82.216.111.124
    82.216.111.125

    After this is confirmed, then attempt to setup the wireless connection WITHOUT security enabled in your router. Remember to disconnect your Ethernet LAN cable before attempting to connect to a wireless connection. You do not want to create a network loop with your laptop ethernet and wireless connections.

    Once you are confirmed that you can connect via wireless, you should then be able to setup a wireless security key using WPA-PSK, WPA2 PSK or WEP. Write down what method you use and what the key is so that you can duplicate it in your wireless setup. If your wireless software uses saved profiles, remember to place this profile at the top of the search order. If there are other nearby wireless devices that have previously been discovered by your wireless adapter, it will attempt to connect to these devices in order of preference. Yours should be first.

    I don't remember seeing anything about wireless security enabled or not...

    I have seen lots of times, that if you're using WEP, with the correct key/phrase, your connection will show 'connected' and 'excellent' but you will NOT get an ip address via DHCP.

    To resolve this, if this is the case, check your wireless settings inside the router and see if it's "open" or "shared" type of encryption... and make sure your windows configuration is the same. For example, in the list of available wireless networks in windows, you can go to 'advanced' and set the settings manually. Check the drop-down menu for 'open' vs 'shared' and adjust appropriately.
