What is a Router  Connects one network to another … Sometimes called a “Gateway”  Connects your computer to the internet (cable modem or DSL Line) – keeps LAN traffic local  Routers keep track of IP addresses and physical (MAC) addresses of hosts  IP (Internet Protocol) address … your computers

internet address  MAC (Media Access Control) … id for each physical communication device Call US On Our Toll Free 1-866-978-8201 for Router Support

What is an Access Point  A point where computers access a network  Device which links wireless users to network  Transmits and receives data (Transceiver)  Bridge between wireless and wired networks

 Can be linked together to cover broad area  No security or firewall implemented Call US On Our Toll Free 1-866-978-8201 for Router Support

What is a Firewall  A device that filters packets of data or traffic  Its job is to be a traffic cop  You configure the firewall:  What will allow to pass  What will it block

 Hides your home network from the outside world  Can be either in hardware or software  Most popular routers for home have built in firewall protection

What Does a Firewall do? They:  Protect your home computer from the bad guys  Keep your information private  Make you less of a target By:  Stopping viruses  Hiding your computer from the world  Making the bad guys work harder to get your info

Configure Wireless Firewall/router Overview 1. Basic Settings … name, ip address, etc Check for firmware updates

2. Set Account name and password Change name and password … don’t used default

3. Wireless Settings SSID broadcast … make sure that remote computers are set to automatically connect

Do not enable DMZ Do enable ping blocking

4. Security - Blocking and Filtering Wireless Security encryption MAC filtering

5. Back up settings Toll Free 1-866-978-8201 Router Support

Basic Settings and Info  Run Install CD that comes with router  Basic info will be automatically entered or requested

 To change info:  For Belkin the default IP address is 192.168.2.1 

Other manufacturers use different ip addresses (later slide)

 Enter this into address bar  Setup page will be displayed

 Firmware - software that is embedded in a hardware device  Updated occasionally by manufactures  Check whenever you access router

Account Name  Change name  Default name is set by manufacturer … eg, Belkin54  Bad guys know defaults and default administrative

passwords

 Create Administrative Password  Use Strong Password

can make changes Router Tech Support on 1-866-978-8201

Passwords Your computer password is the foundation of your computer security  No Password = No Security  Old Passwords & Same Password = Reduced Security  Set and change the “administrator” password on router (and your

Wireless Settings  SSID - service set identifier  name given to your wireless network

 Broadcasting this ID makes network visible to PCs in area  

can be turned off so it will not be detected by other PCs in area Be sure to set up your own pc to automatically detect and logon to your WLAN

 DMZ –  allows you to select a PC to access WLAN outside the firewall  do not enable unless firewall interferes with some activity

 Ping Blocking –troubleshooting tool  Signal sent and echo received indicates valid ip address

 Used by hackers to find active computers  Enable ping blocking … won’t send echo back

Security Blocking and Filtering  Encryption – coding transmissions  Multiple variations. 2 most common:

 WPA-PSK … Wireless Protected Access (Pre-shared key)  Use same password for all computers

 Preferred Choice

 WEP … Wired equivalent privacy  64 or 128 bit encryption … doesn’t matter  Enter Password … converts to hex code  Must enter hex code  2nd Choice (if WPA not supported)

MAC Filtering  MAC address … Media Access Control address  Unique ID permanently attached to each

communication device by manufacturer – hardware id  Can find MAC address: run  cmd  ipconfig/all

 Enter MAC addresses of acceptable network clients  If address is not on filter list, access to network will be

denied

 Very effective security method

RECAP Steps to protect your wireless network

1. Change the default password on your router 2. Enable WPA(PSK) or WEP on router and wireless workstation 3. Use MAC address filtering 4. SSID broadcast off 5. Prohibit Peer-to-peer (Ad Hoc) networking 5. Keep current on hardware bios upgrades
