Extend your wireless network

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

Note:  IP addresses and MAC addresses in this demo are in a controlled lab environment

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.

Tomato RAF

Shibby’s Tomato

DD-WRT

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.

One last thing.  Enable STP (Spanning Tree Protocol) to ensure loop free topology.

Partition your HDD to increase performance

When a good friend gave me a laptop, the quad core (Intel i3), 6 Gb Ram seemed slow.   Thinking back to an old post, Resizing your HDD to increase performance, I decided to see what the difference in performance would be on the 500 Gb Seagate drive that was installed in the laptop if I partitioned the drive.

Most people install Windows and never update drivers.  Below you’ll see a significant gain in speed.

A SSD is much faster and can make your old computer perform like new again (better than new).   But what if you wanted to save money or didn’t want to invest in an SSD?

In order to test the drive, I downloaded CrystalDiskMark and ran a benchmark (one pass 50MB) on the drive.

The first test showed how sluggish the drive was.   Although I had optimized the OS and defragged the drive, 10 MB/s was the best performance it could deliver reading files.

before

Using the Disk Management utility in Windows, I shrank the drive to just over 200GB.  You can experiment with this to find the optimal size.

shrink

Running the utility again, the results were amazing to say the least.

after

While HDDs have become extremely large,  SSDs are the drive of choice for speed.   On desktops, SSDs are ideal for operating systems and at the time of this writing, HDDs are ideal for storage as a second drive.   SSDs will bring enormous performance to laptops but you may just want to partition your drive for the time being.

But what if you wanted to squeeze a little more out of your drive without doing anything really special?

Make sure you open the device manager and select the properties of your HDD and check both boxes under policies.

After after cache

Next, update the drivers on your HDD controller.  You can start at the computer manufacturer’s website.

Note: Most manufacturers stop supporting computers after a year or so and don’t update the drivers under their support section on their website.   One thing not to look over while you are there is BIOS updates.

Going to the manufacturer website can tell you what exact hardware is in your computer.   This in turn can lead you to the manufacturer of the hardware.  Once you find the hardware information, you can go to the hardware manufacturer’s website and download the latest driver.

Note: Manually installing the Intel drivers on this test computer resulted in more up-to-date drivers than the Intel Driver (Automatic) Utility.  Also remember that after you install an AHCI driver,  a reboot my undo the drive policies tab (above).  If the boxes become unchecked, go back and check the policy checkboxes.

after after driver

The end result in this test?  Not bad.

After after

One last thing…SSDs can get more speed out of updating their AHCI driver or Chipset driver. Make sure you update these drivers for the best speed.

Test your network speed

Need a quick way to check your network speed?  You can use TotuSoft’s Lan Speed Test.

This small (124kb), excellent program allows you to transfer data packets from one computer to another across your network.  TotuSoft offers advanced versions of this tool (Go check them out!).

lanspeed program

Install the program on each computer and open with Administrative privileges.  Navigate using the browse button to find a shared folder (create one on each computer) on the opposite computer.

1 lanspeedtest

(Note:  The picture above is a virtual computer on a separate computer than the sending computer.)

Above you will see a test folder on Windows 10 Tech Preview.  The first test was a 20 megabyte file transferred to the Windows 10 computer.   The result was 65Mbps.  On a 100Mbps network this can be normal.   You can expect a throughput of around 60+ percent on a busy network.

This is my home network while streaming videos and transferring files (backup) at the time of the test.

Speed

What happens when you put the computers on a 1 Gbps wire and transfer a gigabyte of data?   375 Mbps.

Go to logs in your router.  You should see ADBlock loaded.   While this will not get rid of all of the ads, you will notice that most are gone.  Can’t get to a website?  Enter the website in the above code on the router to whitelist the site.  Save and Reboot.

Want to remove it?  Open your router’s webpage, delete the code and click save.

Cannot update to Windows 8.1 or Windows 8.1 Update

Can’t get the Windows 8.1 Update from the Microsoft Store?  Have an administrator issue?  Here’s one solution.

Hit the Windows key + R

Enter control userpasswords2

users

Users Panel

Highlight the account and click properties (Note: If you are logged in with your email, create a new account and click properties to make sure the account is an administrator.)

Make sure you are an administrator.  If necessary, create a local account and make sure the account is an administrator.

Bonjour, the chatty protocol

Although an older article, it is important for IT personnel to tackle network traffic and provide a fast, clean and efficient network.

Bonjour is a chatty protocol, and with hundreds or thousands of Apple clients on a network, multicast traffic quickly swells to startling percentages (some universities report instances where this discovery traffic amounts to 90% of the network’s load)…read more
