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.

HP Pavilion 11 x360 Review

I usually don’t review hardware products but I felt a need to review HP’s Pavilion 11t-n000 x360.   

My father-in-law wanted a Microsoft Surface but still wanted a keyboard and the functionality of a laptop.   He also wanted to avoid the expense of a Microsoft Surface and wanted something with a small profile, light weight, lots of storage and plenty of ram for traveling.  He found the HP Pavilion 11 x360 that has the following features:

  • Quad core Pentium 2.17 Ghz
  • Windows 8.1 64bit
  • 4 GB DDR3 
  • 500 GB HD 
  • Beats Audio
  • less than 1″ profile
  • Screen 11.6″ (Touchscreen)
  • Gyros built in
  • 1 -USB 3.0
  • 2 -USB 2.0
  • Wireless 802.11
    • Miracast compatible 
  • Ethernet Port
  • 5 hour battery life (45 watt AC adapter)
  • SD Mediacard Reader
  • 12.12 x 8.46 x 0.86 in 
  • 3.08 lbs
  • HDMI
  • TruVision Webcam
  • 1 year warranty

I expected the laptop (netbook?) to be slow.  I was surprised at how responsive it was with 4GB of RAM.  It is by no means a powerful gaming computer but is a match for home, business or school users.   The pc is upgradeable to 8GB and a hybrid hard drive which would make a difference in performance.  Is this necessary for the typical user?  Probably not.

Once you setup a Microsoft account, Windows 8.1 has the Microsoft store (which now has over 400,000 apps ) and OneDrive to backup and sync pictures, files and more. 

With the HP Pavilion 11, you can fold the keyboard to have a tablet or you can flip the keyboard down and use the pc in ‘tent’ mode so it supports the tablet functionality.   Folding the keyboard under the touchscreen gives you a tablet.   The touchscreen is very responsive to the slightest touch.

At $399,  I don’t know why you would buy a laptop or a tablet.

Going to take a certification that involves binary?

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

 

Flip over and see the answers
