WiFi Standards

Wireless or WiFi networking is very common these days.  With so many devices capable of WiFi networking, it can be a challenge to make the all “talk” to each other.  We are experts in wireless networking.  Need to print from your iPad or iPhone or even iPod Touch?  Need to share files or printers with other computers in your home or office? Or maybe you want to enjoy streaming movies from Netflix or other favorite site to your TV.  We can get you setup to work more conveniently and enjoy the pleasures that technology brings to our lives.

WiFi works on the 802.11 standard that was first developed in 1997.  Over the years, many revisions of the 802.11 standard became common then outdated. Today, the most common WiFi standards are 802.11g, n and the new ac.  We’re going to talk a little about each.

  •  802.11g is becoming obsolete as it has a maximum throughput of 54Mbps.  It operates at 2.4Ghz giving it wide coverage indoors. But because it operates on the 2.4Ghz frequency, it is prone to interference with other common household products (cordless phones, baby monitors, microwave ovens, for example).  While the data rate is adequate for most internet surfing and email, watching a streaming movie while other wireless activity is going on, such as downloading large files or playing online games, it can be a problem as the bandwidth required isn’t enough to sustain all of the activities of all wireless users without occasionally buffering.

 

  • 802.11n is a replacement to g, offering backward compatibility while increasing throughput to nearly 600Mbps.  But this is almost unachievable and usually throughput is around 54-115MBps.  It operates on the 2.4Ghz or 5Ghz frequency so it can overcome some of the interference issues that 802.11g suffers from.  However, with the 5Ghz frequency, range is less than that of the 2.4Ghz frequency because the signals are more easily absorbed by solid material such as walls due to the smaller wavelength.

 

  • 802.11ac is the newest standard.  It operates at 2.4Ghz and 5Ghz and enables higher throughput at the 5Ghz frequency through higher RF bandwidth and high density modulation, allowing WiFi speeds to achieve 1Gbps.  Like it’s predecessors, 802.11ac is backward compatible.

Whichever WiFi you have, the maximum throughput rate is always going to be defined the wireless card standard employed by your device.  So even if you have the newest, hottest, and fastest WiFi router, it doesn’t mean your wireless device can go that fast.  Check your wireless device specifications to ensure it will be compatible with your router.

 

WiFi Security

 

When you are setting up your home internet security it is very important to not rush through the process just to get the job done, take the time to set it up to ensure your data is secured.

Take the time to change the default password.  We have visited so many customers who have left the default password settings that came with the equipment.  These passwords are easily accessible on the internet and to hackers.  This being said, change those passwords, it is critical.

Change the Default SSID.  The default SSID is something like “Netgear”.  This is a signal to hackers that the connection is probably not secure, poorly configured  and easily attacked.

Assign static IP addresses to devices.  For ease, many home based networks are set up with dynamic IP addresses.  Unfortunately, networks setup in this manner makes it easier for hackers to who easily obtain the IP addresses from the DHCP pool for your network.  Turn off the DHCP on the router or access point and set a fixed IP range.  You then set up each device to match those numbers.

Enable Firewalls on Computers and the Router.  Make sure that your firewall is enabled on the router.  For additional security, install and run personal firewall software on each computer that is connected to the router.

Creating a secure home network is imperative to protecting your data.  We can come to your location of log in remotely to check your network is setup in a manner that offers you the most protection available.
