Help! I've had a wireless network using my d link router for a year now. all of a sudden my laptop can't get on and on the available wireless networks it keeps showing several different ones but not mine anymore. i've tried system restore but nothing. ive reset my router, nothing. i've tried to go to run and then ipconfig and now the usual black box with a prompt only shows up for a second and disappears.it was just working! help

someone might be using ur connection

Yeah... sounds like a few people in your area are using your connection. Are you using WEP security? If not then any one within range can hook into your router.... just some simple foot work involved.

Most (all?) wireless routers allow you to restrict access to those wifi cards you allow; all others are excluded. You usually have three/four options: "anyone" allowed; only these allowed; any but these allowed...; and of course the fourth - no-one allowed... The list is based on the mac address of each wifi device. So you need to know what that is for each of your wifi devices. Also hide the ssid (the router's "name"); if you do not hide it then it broadcasts itself to all and sundry - and they will use it.... You can also change this to another name known only to you... If you change it - then you have to tell each wifi device what the new name is... and to use that device (access-point). M$ provide this basic approach KB: http://www.microsoft.com/windowsxp/using/networking/learnmore/bowman_05february10.mspx and these two have useful how to etc... http://www.securitypipeline.com/news/163700023 http://www.wi-fiplanet.com/tutorials/article.php/2026541 I suggest you first reboot the router; reset/renew/re-install all your entries/settings - with above the ssid/mac address info (as above) in mind. Initially do not involk/use the wpa/wep security options... BUT do use the mac filtering approach as outlined above, and also hide/change the ssid. Then when you are able to connect again to the router and the www, use whichever security option you feel comfortable with... If I can find my references to two other excellent/detailed "how to" articles (the references are on another PC) I'll post them here later.

d-link sucks...I know, because I have several routers and network adapters. Anyway, which router do you have? If it has Super G, and your laptop has it inactive, you'll see two wireless networks instead of one (it happened when I re-installed the laptop's drivers). When you do ipconfig, you're supposed to go to Start->Run, then either type "cmd" or "command" (without the quotes). Then you type ipconfig there. If you type it from the Run box, the black "dos" box will close itself when ipconfig is done. All wireless routers come default with the security disabled (to make it easier for people to set up their networks). Thus, anyone can get on your network. As for changing the router settings to lock you out, they can only do that if they found out your password. Here's what I would do. First I'd make sure it really is a router problem and not a modem/ISP problem. Connect a computer/laptop directly to your modem to see if it works. If the internet is working, the next component you should work on is your router. First, reset your router (poke a paper clip into the reset hole). You'll only be able to set up the router hardwired (ie: you can't set it up wirelessly, since the wireless radio is off by default). Follow the d-link instructions on setting up the router for the first time. If you're able to set everything up at this point, be sure to set up your wireless security. Make sure you don't turn on "remote management", as this will allow outsiders to attempt to hack into your router and change the settings. Turn on encryption. WEP is the most basic type of encryption, but can easily be cracked. WPA-PSK is the better choice, but not all devices are compatible with it.
