In This Presentation:
  • Types of Internet access, basic layout diagram
  • Improving your Internet experience (routers)
  • Learn what NOT to do on the Internet
3
Four familiar types of Internet Access:
  • Each type of access has a unique set of strengths and limitations inherent in the various technologies.
  • DSL
  • CABLE
  • SATELLITE
  • ColusaNET Wireless Broadband

"DSL
With DSL"
  • DSL
    With DSL, both phone and Internet signals are combined and sent over the same pair of wires.  Bandwidth (speed) is severely limited, range is typically less than a mile. DSL was the first true broadband service but is late 1990’s technology.  Prior to DSL there was only ISDN which was very expensive.


5
"2.CABLE"
  • 2.CABLE
  •    Internet access over CABLE is a shared model based on cable “segments”.
  •    Multiple neighborhoods can share the same cable segment.  It is largely the same as early Ethernet networks where coaxial cable was “daisy-chained” from one device to the next. While easier to set up, one break in the cable results in a loss of service for everyone on the segment.
6
"3.Satellite"
  • 3.Satellite
  • Satellites are great for some things, such as one-way delivery of TV signals, but they’re not the best choice for the Internet if you have local, terrestrial service available.  This is the result of the enormous distances involved; the round trip to the satellite and back is over 70,000km.  Even at the speed of light, this takes over a half second, and is very noticeable.
  • Latency from terrestrial wireless service is generally under 10 milliseconds.  This makes an enormous difference in your Internet speed and performance.


7
ColusaNET Wireless Broadband
  • ColusaNET Wireless Broadband is unique to this area.  For over 12 years ColusaNET has been the only source of state-of-the-art Internet connectivity solutions.  Speeds exceed DSL and cable combined!  From residential service all the way to dedicated T-1, ColusaNET is unsurpassed in network engineering, performance and diagnostics.


  • Our newest systems are capable of up to 14 megabits split between upload and download in any desired ratio based on service level.

9
Improving your Internet Experience
  • Your Internet performance is largely controlled, or limited, by not only your choice of network components, but also your computer itself.
  • The fastest Internet speeds can only be realized by understanding WHAT NOT TO DO!
10
Improving your Internet Experience
  • The least troublesome and fastest possible network has only one computer!!  That is, nothing but the terminal itself.
11
"If you have a router..."
  • If you have a router on your home or office network, YOU HAVE TOO MANY ROUTERS!
12
"Due to the volume of..."
  • Due to the volume of routers on store shelves, everyone thinks they need a router, if not several routers!


  • There is no need for even a single router in any home or office network.  Every router adds more delay, and nobody needs a router.
13
"Sometimes we see customers who..."
  • Sometimes we see customers who have 3 or 4 routers plugged into each other!!


  • Having even ONE ROUTER on your home network will slow things down unnecessarily.
14
"To connect several computers and/or..."
  • To connect several computers and/or printers together, GET A SWITCH, NOT A ROUTER. (They’re cheaper too!)
  • While they may both look nearly identical, there is a big difference; they are NOT THE SAME THING!!!

16
About Firewalls
  • A FIREWALL stands between you and the Internet.


  • Firewalls are based on rules; they block any incoming traffic not specifically requested by the users it protects.
17
About Firewalls
  • Put another way, a firewall blocks all traffic from the PUBLIC SIDE of the firewall *UNLESS* the connection was initiated from the end user on the SAFE SIDE of the firewall.
18
"A ROUTER is not a..."
  • A ROUTER is not a switch
  • A FIREWALL is not a router
  • A SWITCH is neither a firewall nor a router
19
"If you don’t have specific..."
  • If you don’t have specific knowledge about routing, you have no reason to ever buy a router.
  • To connect the devices on your home or office network, you want a SWITCH, NOT A ROUTER.
20
"Don’t waste the extra money..."
  • Don’t waste the extra money to add delay and additional failure points to your network when a simple and less expensive Ethernet Switch is all you SHOULD be using.
