Locate/identify the IP Configuration on a Windows device (e.g., computer), not a network device
1) Right-click the Start Menu
2) Select Windows PowerShell / Command Prompt / Terminal
3) In the command prompt, type “ipconfig /all” (make sure there is a space before the /)
4) Record the IP address, Subnet Mask, default Gateway, and DNS Server that was assigned to the computer
What are the Network Host Configuration parameters?
1) IP Address
2) Subnet Mask
3) DNS Server
4) Default Gateway

What are the steps/instructions for running a Ping?
1) Open Command Prompt on computer
2) type: ping [domain name or IP Address] -n 4
How do you look up your computer’s MAC address?
Command Prompt –> ipconfig /all –> enter –> Computer’s MAC address will be in the first Ethernet Adapter section as the “Physical Address”
How to lookup a MAC address’s manufacturer via the Internet?
Go to www.macvendors.com and enter the MAC address and it will list the manufacturer (is not always same as the name on the device)
The first six digits represent the manufacturer, the final six represent that specific device
Command prompt to identify the IP addresses, subnet mask, gateway, and DNS server
ipconfig /all
Command prompt to run a ping using an IP address
ping [IP Address] -n [number of pings to run], e.g., “ping 192.168.1.1 -n 4”
Command prompt to run a ping using a domain name?
ping [domain address] -n [number of pings to run], e.g., “ping www.amazon.com -n 4”
Explain how to manage a “combo unit” form an ISP
- disable the combo unit’s wireless
- connect only the router to the combo unit
- put the combo unit into bridge mode
What is the equation to determine a Power Budget?
Power Budgeting = maximum amount of power the device can provide - the sum of the watts required to power each device
*You want to leave 15% of headroom in the power budget for some wiggle room
Example:
Power budget = 65W possible - 45W required = 20 W
↑ headroom = 31%
How and why should you implement separate SSIDs for the 5Ghz and 2.4 GHz bands
First, setup the 5GHz band, then build the 2.4 GHz band to setup devices that still require 2.4 GHz (printers, thermostats, URCs, etc).
Once the two SSIDs’ band have been optimized, then join them into a single SSID
