    I have a Dlink DGL-4300 and two xppro sp2 laptops with Dlink DGL-650 cards to run "super g" mode. I use the windows wireless utility, not DLink's.

    Sometimes when I boot the computers one of them cannot obtain an IP address (limited or no connectivity error), the other will be able to. I can plug in an ethernet cable and it works. I reboot the computer and still not working. I reboot the router and it generally fixes things but this is inconvenient for people. When it is not working, I can manually assign an IP address on my laptop and I get an immediate connection. When it is not working, I can connect to my neighbors router without problems. It will work often when I see a very low signal from my neighbor. I have called Dlink and they don't know. I made no changes to my computer really, I used to use a netgear wireless B and never had connection problems.

    Any ideas on how to keep consistent connections with my Dlink? :)

    I figured I was not the only one. I have called technical support a couple times but they have provided conflicting and not helpful advice. Rebooting the router seems to be the only consistent way to fix the wireless connection problem. Sometimes I can manually assign my IP address and it will work, but oddly, sometimes I will get a connected notice but still cannot connect to the router wirelessly. I have to reboot with an ethernet connection. Maybe they will patch it.

    The DGL-4300 seems to be a good router. I had the same problem with wireless when I first set it up. The fix that I encountered was kind of silly but I tested it numerous times and am sure that it is the cause. Ready for this?? I'll bet that your SSID name is in all capital letters, change it to all lowercase and then try your wireless. After I did this connects with no problems everytime. Changed it back to all uppercase and started failing again. Try it and let me know if it works for you. :D

    Are you by any chance using Windows XP SP2? If you are, then there is a bug that causes some computers to fail to recieve IP Addresses. Microsoft already offers a patch for this, which you can download here:
    http://www.microsoft.com/downloads/...d2-5034-4bbb-b74d-ad8430a1f7c8&DisplayLang=en
    Hope this helps, since I used to have this problem as well.

    If you are still experiencing this error message even after running the patch shown above, you may be experiencing one of several problems shown below:

    1) Your Network or DSL router may have bad or missing information. Powercycle your router and/or rebuild the configuration in your router.

    2) Double-check your cabling to the computer. Make sure you have the correct type of cabling, straight-through CAT 5 or possibly a crossover cable and try another cable or test the cable to make sure its working properly.

    3) Check your network card to make sure its configured correctly and working properly. Many times setting the network card to 10Mbps/Full Duplex will solve this issue. To do this, open Control Panel, System, Device Manager. Go to the properties of the Network card, click on the Advanced tab and find the Link Speed and Duplex section. Change it from Auto Detect to 10Mbps/Full Duplex.

    4) Check and test your firewall. Your firewall, especially if its a software firewall like ZoneAlarm, Black Ice, Norton Firewall or something else could be blocking the connection. Disable your firewall and test the connection. You may have to resolve the problem by even uninstalling and reinstalling the firewall.

    5) Check your IP address assignments and workgroup settings in the computer for accuracy.

    6) Reset your TCP/IP stack by downloading and running WinsockXPFix.exe a Visual Basic program designed to fix corrupted TCP/IP issues, host file problems and a variety of other connectivity issues.

    Thanks for your tips. My ssid was a mix of lower and uppercase letters. I changed to all lower case and had a problem the next time I tried to connect. I switched to the 54g speed and have had no problems for the past couple months. I'll try your suggestions, but it appears to be the superG mode has some glitch.

    Most of the so-called "turbo" modes in 802.11b/g will cause various issues, depending on the exact equipment and configurations in use.
