Securing your wireless network is a simple process, which generally does not require a lot of time. Please follow these instructions to secure your wireless network. Accessing the Router 1. Go to your desktop and double click on Internet Explorer (Located on the Start Menu in Windows XP) 2. When "Internet Explorer" opens type the "Address" bar and click on Go 3. The "Enter Network Password" window will appear. 4. Skip user name and type admin (admin is the default password) as the password, and click OK Setup Page Security Options When you arrive at the Setup page, you'll see the bulk of your wireless security features. There are three things you're going to want to set on this page: 1. SSID a) Delete linksys from the "SSID" field b) Input your own unique SSID. We general recommend something easy to remember, but secure enough to where people would not be able to guess it easily. Sometimes your best bet is to use your last name and add some numbers. a) Click Apply then Continue 1. SSID Broadcast (Firmware 1.42.7 and above only) a) Click No on the Allow "Broadcast" SSID to associate? b) Click Apply then Continue 2. WEP a) Click Mandatory for the "WEP" Option b) Click the WEP Key Settings button c) When the "Wep Key Settings" Window appears, change the option from 64 to 128* NOTE: 128 bit WEP may not work on non-Linksys products due to its lack of an IEEE standard d) Enter a passphrase** that is different from the SSID. Try to make it alphanumeric; instead of password, use password5532. Once the key has been Generated copy the key into a notepad document and copy that file onto a floppy. **NOTE: The passphrase will not work with non-Linksys products, so you will need to use the passphrase that you copied onto floppy. e) Click Apply then Continue f) Close the window g) Click Apply then Continue on the setup page. Setting up Station MAC Filter The Station MAC Filter option is a very good security feature that has been added to Firmware 1.42.7 and above. This option denies all wireless clients except those listed. To implement this feature please follow these instructions: 1. From the "Setup" page, click Advanced 2. When the "Filters" page opens, click on the Wireless tab 3. Make sure all wireless computers are setup to the router, and are currently able to access the internet. Once this is done, click on the Active MAC Table button. 4. Move the "Wireless Active MAC Table" window and click on Edit MAC Filter Settings on the main window. 5. When the "Wireless Group MAC Table" opens, go to the task bar and click on the Wireless Active MAC Table so that window appears. 6. With the two windows side by side enter the MAC Addresses from the "Wireless Active MAC Table" window into the Wireless Group MAC Table. - NOTE: When you enter the MAC Addresses do not include the dashes, and do not click "Filter" 7. Click Apply then Continue in the "Wireless Group MAC Table" window. 8. Close the "Wireless Group MAC Table" window and the "Wireless Active MAC Table" window 9. On the Main window Enable the Station MAC Filter setting.

You can secure your wireless network wit WEP or WAP code.
For that Connect your router to computer with ethernet cable then you can access it with following default link.
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 "1234" blank.
Then you can see configuration page of router.
If you are not able to access router then RESET it .You can RESET it with reset button it is in back side of router press it for 10 seconds then all settings goes to defaults then you can access it with above link.

Problem with linksys router

You won't be able to get into the internet until you configure your router - hence the security screen. Go to the Linksys book (or "quick start) that came with it should have given you the router's address and password (for instance linksys. It'll also give you password instructions for when the security screen comes up. ) Once you're into your router's configuration page. You should be able to follow the steps and then you'll be home free. Good Luck or get back to me.

New notebook on wireless network

Your IT guy turned broadcasting off. There is a reset button on the back of your router. Use a pin to hold the button down for a few seconds then plug back into the router with a hard wire to your computer.

Open a web browser on your computer and go to

It'll ask you for a user name and password.
