I haven't got any security on my wireless router and so it seems the whole neighbourhood is using my internet connection. I don't know how to set it so it's security enabled, can you help?

LOL, how did you forget the security key? OK, lets pray for a little luck here. On some wireless routers and some modems that contain wireless capability the security key will be either on the side or bottom of them on a label. It is called the Network Security Key or Network Password. This is especially true if you have AT&T as your provider. If you have a wireless router that you purchased from a store such as Netgear, Dlink, Belkin, etc. then you will need to use a Network Cable to plug the wireless router into the computer ( it may already be plugged up if you have a desktop computer). On the computer with the network cable coming from the router plugged into it you will open up internet explorer and in the address bar you will type in the ip address of the router. For example the ip address for netgear might be 192.168.1.1 so you would put that in address bar where you normally type www to get to webpages. If you have access to a computer that is already connected to the internet just get on it and go to www.google.com and in the search type for example "netgear wireless router ip address". you'll find the ip address, or you can go to your router manufacturer's site to find the ip address. You 'll also need the userid and password to get into the router, so make sure you google that or get it from the manufacturer's site. Most times the router might be set to the default user id and password. Let's hope that's the case otherwise you'll need to get it from whoever set up your router. Once you're in the router, go to the wireless settings and look for the password. It might be under wireless security or it might just be under wireless. That's all there is to it.

I know it seems like a lot, but it's quite simple. The only thing that might throw you off is if whoever set up your wireless also changed the default userid and password to get into the router. Don't fret you can get around it by clicking the little button on the back of the router with an ink pen and hold it for about 30 seconds. This will reset the router to the factory settings including the password. You'll have to go back into it and turn on the wireless and set a password if you want one to secure it. Also if your internet connection is a PPOE Connection which is what phone companies use such as AT&T then you will have to put in your Network or Internet Userid and Password. Most folks don't know that because they think the only userid and password they have is their email userid and password from the phone company. NOT TRUE.... You'll need the Internet Password or you'll never reach the internet. In fact you might spend time talking on the phone to a customer service rep to get it all set back up. And they won't help you with the router because the don't deal with anything that's not their product. So in short HIT THE RESET ON THE BACK OF THE ROUTER AS A VERY LAST RESORT.

Is it asking you for wireless network key?
You need to check the wireless settings of your router.
Connect one computer to the router with the Ethernet cable.
OPen the setup page of the router and check the wireless settings of your router.

Hello.
- This error occurs when the wireless security that you set on the wireless laptop does not match the wireless security on the router.

• If the wireless router's security setting is WPA but on the laptop you used WEP for the wireless security, that's when a mismatch occurs.
  

- What you can do to resolve the problem is to delete the wireless profile you created on the laptop. After that, let the laptop search for wireless connection available, select the correct wireless settings and it should connect.
--For example the operating system of your computer is Vista, in order to remove the wireless profile you created and reconnect to the wireless router, do the following instructions:- Go to Start>Control Panel>Network and Internet> Network and Sharing Center- Click on Manage Wireless Networks on the left panel. Delete the wireless profile then Search for available wireless networks again. Type the correct wireless security settings on your laptop
-- If you would like to know what wireless security has been setup on the router, connect the laptop or use a desktop which is wired to the router then access the router setup page by typing http://www.routerlogin.net or 192.168.1.1 in the address field of your browser and then press Enter. Enter admin for the router user name and your password (or the default, password).

--After logging in. In the main menu on the left, click on Wireless Settings, from there you can check the wireless security or you can setup wireless security from there if you haven't done so.

Hope this helps. Have a nice day. Don't forget to vote if you find this guide helpful. Thanks.

Connect your router to computer with ethernet cable then you can access it with following default link. http://192.168.1.1 or http://192.168.0.1 or http://192.168.15.1 or http://192.168.2.1 If you are not able to access it with above ip then check your computers ip address gateway ip is your router ip try with it. Then it ask for user name and password. Type user as "admin" and password as "admin" or "password" or blank. Then you can see configuration page of router. If you are still not able to access router with above ip then you need to RESET it for that press RESET button for 10 seconds it is in back side of router then all settings defaults..Then you can access it with above method. Then click on WAN settings set it as your internet service provider settings enable DHCP Then click on wireless and enable it. . Then click on wireless->wireless security->WEP security there is code password note down it or enter new password then save setting s and restart router. then you can connect wireless with new password. Let me know if you need further assistance. Thanks for using FixYa.

How is your internet security set? Try resetting your router to factory specs and see if your laptop works. I know it seems weird that only one computer wont connect, but try a different router, and try a different security setting within your wireless router.

download inssider and install it, scan your neighbourhood with it and make sure no one else is on the CHANNEL you want the NETGEAR to use. Connect the netgear to your pc with a network cable, then use internet explorer to goto to web address 192.168.1.1 or 192.168.2.1 to get you to the routers web page and login in as Admin (check netgear manual) password may be blank. Now make sure that mac address filtering is either NOT enabled or enable with your PCs address on the exceptions list. Make a note of the SSID and change the wireless security WPA-PSK code to one you can remember. Enable BROADCAST on the SSID. Save all settings and then reboot it and unplug your network cable, then try to access the router wirelessly, if it all fails, go back into the router and check that your settings were remembered, sometimes a router fails to save changes if it does this after several attempts get a new one.

Login in using your browser and go to the wireless settings and set-up a wireless password/key. Remember the key because each device will now need it to connect. You can also turn OFF Broadcast SSID and your network name will not be shown on anyone's device. You must remember the network name when using this method.

First connect your router to computer then access your router as following link.
http://192.168.1.1
or
http://192.168.0.1
type user as "admin" and password as "admin" or blank or "password"
Then you can see configuration page .
Then set WAN settings as your internet service provider settings.
Enable DHCP.
Go to wireless enable wireless.
SEt wep security if you want secure wi fi.Add WEP code it is your password to connect internet so only who know the password are connect to your wi fi .
Then save settings and restart router.
Let me know if you need more assistance.
Thanks.

You need to access the setup page of your router by typing this to the address bar 192.168.0.1 using the pc that is connected to it and there you can find a wireless portion that's where you can secure it.
