Configuring WDS to extend your wireless network

Want to extend your network and make it more reliable and robust?   

Here’s what you will need -

  • Two routers with the same firmware
    • Preferably Tomato or DD-WRT

Login to the first router.  

In this example, the static number 192.168.1.1 is the Main router.

  • Enable the WAN to match your ISP  
  • Enable DHCP
  • Enable Access Point + WDS  (Picture two below)
    • You must have the same wireless configuration on both routers
      • Enter the MAC address of router two under WDS Link with.

Router 1 no 1

Router 1 no 2

Login to the second router

  • Disable the WAN
  • Disable DHCP
  • Assign the router a static IP address (Below we have given the router .250)
  • Enter Router One’s IP Address for the Gateway
  • Enter a DNS of your choice
  • Make the wireless configuration the same as the first router.  Under WDS, change the drop down to automatic.

Router 2 no 1

Router 2 no 2

With the same settings, you can now extend your network several hundred feet under the right conditions.  Because the SSIDs are the same, once you join one of the routers with a smartphone or laptop, it will seamlessly change to the stronger signal.

With Tomato, you can chain together approximately 12 devices.

Note; The IP addresses and MAC addresses are in a lab environment.

How does it look on a network map?  The two routers are actually connected together.  The switch is the four ports on the back of the router closest to the internet.

Wi-fi takes a long time to find network after computer sleeps

After your computer goes to sleep, do you notice it takes a long time to connect to your wireless router?
slow
There can be several reasons for this.

Here are some tips~

  • Power management on the adapter is enabled
    • Disable in the Device Manager
  • Advanced Power Management
    • Disable under Power Options (Advanced)
  • Bluetooth Interference
    • Disable under the advanced tab on the wireless network card properties
  • Outdated Driver
    • Updated the driver from the manufacturer of the wirelesss chip and not from the computer’s support site
  • Disable the Virtual Wi-fi under the device manager if you don’t use Adhoc

Advanced Power options – Set to Max Performance

Use the following freeware to see if you have channel interference and to analyze the power in each room of your home or business:

Vistumbler
NetSurveyor
Xirrus

 

Ultimately, reset your network by going to a command prompt as an administrator and type the following:

netsh int ip reset reset.log
netsh int ipv6 reset reset.log
netsh winsock reset catalog
nbtstat -r
nbtstat -RR
ipconfig /flushdns

Restart your computer

Going to take a certification that involves binary?

Here’s a quick tutorial~

Let’s say you are given an IP address of 192.168.1.135 in an answer.

What is this number in binary?

Here’s what you do.

Take a simple key to convert the numbers in the octets into binary.
The key is this:

128   64   32   16   8   4   2  1

Now let’s take the first octet of 192 and let’s see how many times the numbers above (the key) go into the given octet.

How many times does 128 go into 192?     192 – 128        1 time
This will leave us 64.
Next, how many times will 64 (your remaining number) go into the next number in the key(64)?

64 -64       1 time

Now the remaining number is 0.   So if you subtract 32 from 0 the number will be 0.  16 from 0 is 0, 8 from 0 is 0, 4 from 0 is 0, 2 from 0 is 0 and finally 1 from 0 is 0.

Look at your answers. 11000000 -This will represent 192.

Now let’s do the 168 octet.

128 goes into 168 – 1 time.   The remaining number is 40.   64 goes into 40 – 0 times.    32 goes into 40 – 1 time.  This gives you a remainder of 8.   16 (the next number in the key) goes into 8 how many times? 0 . 8 goes into 8 – 1 time.  The remainder is now 0.    4 goes into 0 – 0 times.   2 goes into 0 – 0 times.  1 goes into 0 – 0 times.   Look at your answers (bold).

168 will be 1010100

Of course the next number (third octect) which is 1 will be 00000001.

If you use the above key for 132, along with the subtraction method, 132 will be 10000100.

Your final answer is 11000000.1010100.00000001.10000100

 

Try a these yourself using the subtraction method above -

192.168.1.32
192.168.1.111

An introduction to Big Data – RackSpace’s CloudU MOOC

CloudU

Several years ago we introduced you to CloudU. A perfect introduction to how the ‘cloud’ works.  CloudU by RackSpace now has a MOOC (Mass Open Online Course) that introduces you to Big Data.

According to Wikipedia, Big Data is a term used to describe a collection of data sets so large and complex that it becomes difficult to process using on-hand database management tools or traditional data processing applications. Thats a great definition but its only one. This topic is too big to base this learning series on one definition so we asked the brightest minds in academia and the cloud industry the same question, “What is Big Data”? We are confident you will enjoy their insights and take away a broader perspective on big data.       Sign up, it’s free (Link)

Earlier Post

“After contacting Rackspace so that my students could benefit from the cloud university curriculum as a supplement.   I was met with open arms and personally talked with Greg Alfaro, Michael Ferranti and Ben Kepes either by phone or email.   Here’s a quote from Ben. - “CloudU is an excellent resource for anyone wanting to learn about Cloud Computing. As an instructor of information technology, the certificate provides a great learning tool for the planning, deployment and logistics behind cloud computing.”    ~ Ben Kepes
