Transcript

  • 1. Home Networking MacPeople MUG October 11, 2012
  • 2. How It WorksInternet connections comes in from your ISP, is translated through yourCable or DSL Modem, then sent to your Router for distribution.
  • 3. Wireless RoutersApple Airport Extreme Apple Airport Express Linksys WRT54G D-Link WBR-2310
  • 4. Wired Options• Most wireless routers also include wired ports that allow you to connect other devices such as Printers and Hard Drives to be accessible to the network, and Ethernet ports for other network devices. Back of Airport Extreme
  • 5. Flavors of Wi-Fi• There are three commonly used consumer levels of Wireless Networking. • 802.11b, 802.11g and 802.11n• These protocols are certified by the IEEE (Institute of Electrical and Electronics Engineers) to create a standard and insure interoperability
  • 6. What’s the Difference? Theoretical TypicalProtocol Release Frequency Range Speed Speed802.11b 1999 2.4GHz 11 4.5 35m802.11g 2003 2.4GHz 51 23 35m 2008 (draft) 2.4 or802.11.n 248 74 70m 2009 (final) 5GHz*Speeds are measured in Megabits/second
  • 7. Interoperability• All 802.11b, g, and n devices can work together. Newer devices are backwards compatible with older standards. • A “g” router will run “b” devices. • A “n” router will run “b” and “g” devices.
  • 8. Interoperability• It’s best to run newer technology when possible.• Routers will have to slow down to operate with an older device, which will slow down speeds for the entire network.• Devices can only communicate with each other at the speed of the slowest component.
  • 9. What To Buy?• Apple’s Airport Products: • Easiest to setup. • Have the ability to connect printers and USB Hard drives to share. • Work with Macs and PCs. • Feature packed• They are also the most expensive devices.
  • 10. http://www.apple.com/wifi/
  • 11. What To Buy?• If you simply want to create a “basic” 802.11n wireless network, a brand name wireless router will work just fine with your Mac.• Setup will be more difficult through a web interface.• Less expensive, typically in the $50 - $75 range.
  • 12. Security is Required!• Give some thought to your Password• WPA2 is preferred• Check for updates to your router’s software.• Security is important! Don’t run an open network just because it’s easier!
  • 13. Use A Guest Network• Uses a separate password.• For internet access only.• More Info: http://support.apple.com/kb/ HT3477?viewlocale=en_US&locale=en_US
  • 14. Solving Common Problems
  • 15. Poor Signal or Slow Connection• Relocate wireless router to central location• Remove Old Devices• Check for interference • Change Channel • Change Frequency• Extend Network
  • 16. Goodbye b & g
  • 17. Watch Your Neighbors• Pick a channel that no one is using to minimize interference.
  • 18. Interference
  • 19. 2.4 vs. 5 GHz
  • 20. Wired is King
  • 21. Powerline Ethernet
  • 22. Extend Your Network
  • 23. Setting up a wireless network extension MacPeople October 11, 2012 Bill Castine
  • 24. • Needed: Macintosh Computer, Apple base station (Airport Express demonstrated), any wireless network using WPA, WPA2, or no security (does not have to be Apple branded, but you must know the password [if any]).
  • 25. • First, open System Preferences>>Network
  • 26. • Then open Airport Utility
  • 27. • Wait a few seconds; however, the indicator lamp on the Airport device will continue to blink orange and will not turn green. After a few more seconds, try your new connection. It should work!
  • 28. Questions?
