How do i put a lock on my wireless router - NetGear WNDR3400 N600 Wireless Dual Band Router (WNDR3400100NAS)

To connect to your wireless router, the router's wireless settings needs to be configured with the SSID, encryption etc. and also the wireless cards in all the laptops/computers needs to be configured with these router's wireless settings. Then the laptops/desktop computers can communicate with your wireless router.
Connect a LAN cable from the Linksys to the LAN port on your computer.
Open a browser and enter the Linksys configuration URL
http://192.168.1.1
The default login = admin
The default PW = admin
You can protect your router by changing the default admin PW (write it down and put it in a safe place)
Go to the wireless configuration and set up the SSID and WPA or WPA2 encryption to protect your wireless network and Internet from unauthorized access.
Now apply these settings to the wireless card in your laptop/computer.
To secure your wireless network from unauthorized access, please click on this link and follow my instructions :- http://www.fixya.com/support/r3559128-wireless_router_security

that symble means that your wireless signal is secure with either wep or wpa-psk or wpa2-psk.that means you have a passphrase set for the wireless part of your router.unless you mean that you put the wrong login password ,either way if you forgot either 1 you can always reset the router to factory specs by pressing the little button in the hole of the router most likely on the back,just use a tooth pick or something nonmetalic to press it in for 30 sec. or till it restarts.Then you will have to reset all of your settings in your router including the passphrase and password.it is best to do all the settings from a connected lan cable and not wireless to start,and you can set everything else up from the same too.

I assume you are talking about putting a password on your wireless router?
Type in: 192.168.1.1 in your web browser, this will take you to the router configuration page. enter the username ans password, if you haven't changed it, they will both be "administrator"
From this page select wireless security
Simply follow the on-screen instructions from there :)
Good luck!

You can enable wireless security on your wireless network by following the step by step procedure from my TIP.

Just click HERE then you can now begin the procedure to enable wireless security on your router.

Reset the router to factory configuration by using a paper clip or similar item to (while the router is on) depress the "Reset" switch on the back of the router. Hold it for about ten seconds, then release. This should put your router back to factory specs. You'll then have to log back in to the router using the web interface and re-enter your wireless settings.

It also sounds like someone perhaps hacked your router. When you re-enter your settings, I suggest you change the user name to something only you know, and also the router access password (not the wireless key) to a strong password that, again, only you know. This should keep anyone from locking you out of your own router.

Hope that's helpful.

You should check the password which you have given for the router. Either you are typing it wrongly or you have forgotten the correct password. Try resetting your password and then try to connect your laptop via that router. Your problem will get solved

To lock or put a password on your Wireless Router is you have to get the Gateway Address of your Router (Firmware) like for example: http://192.168.0.1, to check it in your LAN Network Connection.. Check it there, then go to your Internet Explorer and type it on the Address, (http://192.168.0.1) the ENTER then LOGIN: admin PASS: admin,
To get into your Router Firmware and read all the instruction if you get in to put a password on it.

Ok, to put a WEP key from our router. You need to configure it, by doing that you need ethernet cable (cat 5). You need to connect your pc to your router using cat5 cable. After you've done that, open your internet explorer/firefox ect., and enter your router's ip address (router ip address can be found in manual or at the back of your router). You will be ask for username and password, just key in if you have one, otherwise just enter the default (mostly, username:admin ; password: none/blank ; depends on manufacturer). After you've done that, go to SETUP menu, and go to Wireless setup you can enable WEP key there, just choose your options. Just try it, I hope it helps you.

Go to a computer wired to your router
Open an internet explorer browser
Click on the address bar and type in 192.168.0.1
Type your password for the router.
Normally be default its username admin and blank for password.
Go to wireless on the left side.
Under security type in WPA-PSK
Type in a password 8 charachters or more

ON your wireless computer
Connect to your network name and put in that 8 char password.
