UPDATE: Do everything below using an Ethernet Cable connection. Using Wireless can be problematic.
In this article I want to cover how to secure an Eircom router.
Log Into Your Router
1) Open your internet browser (Firefox, IE, Opera) and type in the address bar: http://192.168.1.254
2) Enter your username and password if you are asked for one
3) You should now be in the routers home page
Setting Up WPA (aka A Wireless Key)
Golden Rule of Wireless: Never use WEP. It is the equilevent of tissue paper. it is breakable in 1 minute. You can break it faster than you can set it up.
1) From your routers home page, click Wireless (Left Hand Side)
2) Give your wireless a name. (Hint: Do not use your address, phone number or real name)
3) Set Privacy to: WPA-PSK
4) Set your Pre Shared Key to a long password. Letters, Number and Symbols are best. Do not use one word. WPA is hacked by dictionary attacks, as such if you use a word in a dictionary it is hackable.
(Download this program: http://www.soroban.co.uk/wepkeygen.htm and create at least a 56 character passphrase Extended WPA KEY)
Simular to this:
5) Copy and paste your new key to NotePad and into the Pre Shared Key box on your router
6) Click Save Changes and say yes to restarting your router
7) Once the router has rebooted, open Windows Wireless Networks, search for your network, then use NotePad to copy and paste your new code in when required
Your router is now almost 100% secure.
1) Log into your router
2) Click Expert Mode
3) Click Statistics
4) Click LAN
5) Connect every device you have to your wireless. Once you have done this, refresh your browser (Press F5)
6) Note every devices MAC Address exactly.
7) Click return to your routers home page: http://192.168.1.254
8) Click Wireless
9) Click Advanced Configuration Options
10) Click Limit Wireless Access by MAC Address
11) Click Add, then add each devices MAC Address, clicking Submit each time.
12) Once finished, click Save Changes and Restart your router.
Explanation: Your router will now only allow devices on the allowed list to connect to your router. This adds an extra layer of protection to your router, thus stopping someone who may have cracked your wireless password from using your wireless. However, MAC Address's can be spoofed, so this is a basic level of protection.
Adding a Router Log In Password (Not the same as your WPA / Wireless Key):
1) Go to http://192.168.1.254/indexExptCfgRES...uterpasswd.htm
2) Create a new password and ensure the box is checked saying "Enable Local Admin Login"
3) Click Save Changes and allow your router to restart if required.
4) Now when you log into your router at http://192.168.1.254 your username is "admin" and your password is the one you just created
Explanation: This password will stop anyone who has access to your LAN or Wireless from changing settings or locking you out of your own network.
- Do not use wireless if you don't have to
- Always use WPA or above. WEP is not secure.
- Never use names, telephone numbers or personal information as passwords or network names
- Don't steal wireless from your neighbour. What goes around, comes around.
- Change your wireless key at least every 3 months if you live in a built up area
- If you suspect your wireless has been hacked, immediately turn it off. Contact your ISP and change your wireless key.
