LAN Diagramming and Testing

Spring 2017

Name:_______________________

Diagramming/mapping your network.

Using either Visio, LibreOffice Draw, or PowerPoint, diagram your own home network. Include the following on the diagram:

THE REST OF THE ASSIGNMENT DELIVERABLES SHOULD BE IN THIS DOCUMENT

  • All hosts on the network, such as computers, tablets, phones, and game consoles.
  • The IP address for each host on your network. This would be the local (probably private) address that your local DHCP server provides. REMEMBER: Routers always have at least two IP addresses.
  • The public IP address assigned to your network (ipchicken.com).
  • List the auto-negotiated link speed for the links to your PCs. This is the theoretical link speed (Bandwidth) negotiated between your host and your router/switch. It can be found by right-clicking on the network adapter under “Control Panel|Network and Internet|NetworkConections” and choose “Status”. (You can also run the command “wmic NIC where NetEnabled=true get Name, Speed” at a command prompt to find the same information.Consult Google if you use a MAC or Linux. You do not need to find this for tablets, phones, and game consoles.
  • If known, the specifications, in terms of network speeds, of your wireless router and any switches and routers included in your network. Common speeds are: 100 or 1000 Mbps (1Gbps) for wired networks, and 54, 150, 300, and 600 Mbps for wireless networks. Hint: If youown the wired or wireless devices, Google is your friend for finding specifications and manuals. If you don’t control them, but can find the model number of the device, Google is your friend.
  • ASUS wireless adapter –
  • Data Rate802.11b: up to 11Mbps
  • 802.11a/g: up to 54Mbps
  • 802.11n: up to 300Mbps
  • 256QAM (2.4GHz): up to 400Mbps
  • 802.11ac (5GHz): up to 867Mbps
  • ArrisSURFboard cable Modem –
  • Donwload Speed: up to 343Mbps

Internet speed test.

LAN Speed tests

  • Run a speed test (using speedtest.net or anothertest site of your choice) on a PC/Laptop. Insert a screenshot of the speed test results here.
  • Run the same test using a mobile device or a game console. Use either a dedicated speed testing app or try http://speedof.me/ in a browser.Insert a screenshot of the speed test results here.
  • Explain any differences in the test results between the devices.
  • There was a large difference in the download speeds of the laptop vs the smart phone. The smart phone has a download speed of 60.25 which is almost double that of the laptop. Yet the upload speed of the laptop massively outperformed that of the smartphone. I assume that is because the laptop has an older antenna, making the reception not as strong as the smartphone. The wifi adapter for the phone is probably way more updated as well.

These tests will test speeds on the wired and/or wireless local network.There is a video on Reggienet under Resources showing how to use LANBench.

Please conduct the following local speed tests. I’d recommend LANBench from http://www.zachsaw.com/?pg=lanbench_tcp_network_benchmark. I WOULD RECOMMEND TURNING OFF WINDOWS FIREWALL FOR THIS EXERCISE. Last, but vital, BOTH MACHINES NEED TO BE ON THE SAME NETWORK/SUBNET.

If LANBenchdoes not work for you, there are several other speed test tools at: https://www.raymond.cc/blog/network-benchmark-test-your-network-speed/ you may choose one of them. Notably, Lan Speed Test (Lite) has a Mac version, but be aware you’ll need to share a folder from Windows to Mac.You are also welcome to use a more advanced bandwidth program like IPERF if you are familiar with it. I believe LANBenchis the easiest route though.

Do as many of the following with the LANBench or another test tool as are possible with your network setup. You may need to talk a roommate into helping by unzipping a copy of the testing tool on their PC/Laptop (No installation necessary for LANBench!).

Gateway laptop

  • A speed test between two computers, both connected to your router/switch using Ethernet cables.Insert a screenshot of the speed test resultsusing LANBenchor your other chosen tool here, or indicate this test was impossible.

Asus Laptop

Wireless –

  • A speed test between a computer connected using Ethernet and a computer connected via wireless. Insert a screenshot of the speed test resultsusing LANBench or your other chosen tool here, or indicate this test was impossible.

Asus Laptop

Wired –

The speeds for the wireless connections tested to be a lower speed than the LAN cable connection. That’s to be expected because physical connections almost always give you faster download speeds. The speed of the router was relatively well matched by what Xfinity has for our plan too. The only thing that I didn’t fully understand at first was the fact that the older laptop was receiving higher download and upload speeds.

  • A speed test between two computers, with both connected to your wireless network. Insert a screenshot of the speed test resultsusing LANBench or your other chosen tool here, or indicate this test was impossible.
  • Asus Laptop
  • Gateway Laptop
  • Considering the speed of your devices found in the diagramming portion, and the auto-negotiated link speeds, explain any differences between the speed you should have seen and the actual speed your tests showed. Be sure to cover all the combinations of speed tests you conducted above.

Your deliverable will consist of two documents:

Submit this document on Reggienet. DON’T FORGET TO TURN YOUR FIREWALL BACK ON IF YOU TURNED IT OFF.

  • Network diagram – use Visio, OpenOffice Draw, or Powerpoint. For Visio, use the icons included in the program, otherwise, use the Cisco set available at http://www.cisco.com/web/about/ac50/ac47/2.html
  • This document, with the screenshots and explanations indicated.
