Tip & How-To about Computers & Internet

Home Computer Networking Tips

• Make sure you have changed the username and passwords for the administrator by default, especially if you use a wi-fi. Hackers can easily access the network from outside the building and has access to your system that all routers come with standard passwords.


• Make sure the firewall on all computers and routers are on. Revoke the privileges that may allow users to set firewall. Installing additional software on each personal computer to help you make your system more secure.


• Assign static IP addresses for each computer. Make sure you create a range of private IP addresses to prevent your computer from being directly accessible from the Internet.


• Set the "Auto connect to Wi-Fi option. Your computer may accidentally connect to a local network that may represent serious threats to security.


• If you have a wireless network installation, then change the default SSID immediately. Also, make sure to remove the SSID broadcast function of network routers.


• The network must be switched on when not in use. Turning often not a feasible solution, but when the network is not required for a period of time, you can disable.


• Enable and use Wired Equivalency Frequency (WEP) that will help encrypt all data transfers via your router.


• Enable MAC address filtering on the network. Also provide the MAC address of your computer to activate the filter. A MAC address is very difficult to counterfeit and increases security of a large network.


• Use a non-standard channel for the wireless network that make it difficult for hackers to access your network.

I cannot connect. I keep getting a message "authentication Failed"


Do you connect your PC to router in an administrator role using web browser? Or do you connect some device to Wi-Fi network?

  1. Administrator role: You need to have correct login name and password for admin access. Search in manual or ask Google for default login name and password of your router type. If non-default password is set in the router then you must reset router setting and erase its settings to default (factory) status. You will lose all router configuration but default password is back.
  2. Wi-Fi client role: There are more possibilities why authentication fails in wireless communication. Mentioned error message describes what kind of problem occurred.
    (a) A password you put to client device does not match the wireless network password which is set in router. Your computer, tablet or smartphone WI-Fi interface must have exactly same password as WI-Fi network which is transmitted from router. Check and compare passwords on both sides, in client device and in router.
    (b) Client Wi-Fi interface security (encryption) mode differs from Wi-Fi network encryption used in router. But the same mode must be set on both sides (client and router) for successful connection.
Encryption modes are
  • WPA2 Enterpise
  • WPA2 PSK ("home")
  • WPA Enterprise
  • WPA PSK
  • WEP
  • No encryption (open)
Higher position - better security. Enterprise Wi-Fi modes require security devices like authentication servers, certification authorities etc. They are not used in home networks usually.

Many households have unsecured wireless networks, which can lead to hackers as well as leaks in confidential information. However, you can password-protect your wireless network by taking some basic steps.

Determine your network IP address by navigating to the "Start" menu and selecting "Run." In the Run dialog, type "cmd" (without quotes) and click "OK." The Command Prompt dialog opens. Type "ipconfig/all" (without quotes) and press "Enter." The command prompt will display a list of data for you network, including your IP address. Launch a Web browser and input your IP address in the address box. The control page of your router is displayed. Refer to the manual that came with your specific router on the manufacturer password/user name to login to your network. Usually the User Name is "admin" or "password" and the password is either "admin" or "password." Sometimes these fields are left blank. After logging into the router you can access the administrative functions. Within the administrative functions, navigate to the security settings. Within the security settings, you can change the username and password to log in to the router. Disable the router's remote administrative functions. Remote administrative functions allow anyone using the Internet to access your router. To be more secure, disable these options. The only reason to enable them is if a network administrator isn't always on location. Change the network's name. Your router comes with a default network name like WLAN or Linksys. These names are referred to as SSIDs. You want to change the name to something that you will recognize, but others won't associate with you. If your name is John, don't call your network "John's Network." Enable encryption and enter a password in the appropriate field. Wireless routers use several types of encryption, including WPA2, WPA and WEP.
At the time of publication, WPA2 (Wi-Fi Protect Access 2) is the most secure encryption format available on some routers. But you can't use this encryption type if your router doesn't support it. WPA (Wi-Fi Protected Access) is recommended if WPA2 isn't available on your specific model. WEP (Wired Equivalent Privacy is the least secure of all the encryption formats and is relatively easy to hack. If you have no other choice, use at least WEP encryption. Some protection is better than no protection.. Record your password and settings for future reference. If you lose your password, you can reset your wireless router to the manufacturer's default settings by pressing the router's "Reset" button, usually found on the back of the unit. Remember to re-secure your network after a reset.

i have no wepkey to network the problem is anyone can browse connecting to my network using wi-fi


  • If you have forgotten your LinkSys router password, the easiest thing to do is to reset your router to the factory default settings.

    To restore the router configuration to factory defaults, hold the reset button on the unit for 30 seconds.


  • 2reset-password-linksys-router-1.2-120x120.jpg

    Once your router is hard reset, you will need to login and reconfigure it again.

    To reconfigure your LinkSys, connect a PC to one of it's Ethernet ports, load a web browser, and go to the URL http://192.168.1.1/. This will take you to a popup box which asks you to enter a username and password to login to your router.
    LinkSys Default Password

    On older LinkSys routers, the default username is blank and the default password is "admin." On newer Linksys routers, both the default username and the default password are set to "admin."

    Once you are past the login screen, you are able to reconfigure the LinkSys router.
    You want to go to the management tab and change the administrator password to something else to keep others from accessing your router.

    After changing the administrator password then you will need to enable WEP or WAP security so your nosy neighbors aren't tapping into your wireless network. I am picking up 4 networks with my pc antenna.


    Good luck

    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.

    Click on wireless settings WEP Security then add WEP code .It is your password to connect wi fi.Then save settings and restart router.

    If your linksys router has the default information, log into it by going to 192.168.1.1 or 192.168.0.1 with your web browser. Log in with the user name blank and password admin or 1234. Go to wireless, then security, there you can change your password for your wifi.
