5/9/24 Difference of WiFi and Internet WiFi Wireless Fidelity -conects divices to internet -uses radio waves to transmit information Internet -public/global/worldwide network -allows access to various webpages and services Internet Waves First - building the foundation of the internet Second - app economy and the mobile revolution Third - internet of things (alpha gen) all devices need internet to function Wireless Standard -a family specs started in 1990s -codified improvements that boosted wireless throughput and range -developed by IEEE for WLAN tech Here are some top router models: TP-Link's TL-WR940N is a high-speed router that supports IEEE 802.11b/g/n standards. Utilizing 802.11n technology, the TL-WR940N provides users with wireless performance of up to 450Mbps, making it suitable for demanding home networking tasks such as HD streaming, online gaming, and downloading large files. NETGEAR's WNDR4300 operates in the 2.4 GHz bandwidth and offers WLAN data transfer rates of 300,450 Mbit/s. This allows for seamless wireless communication over a wide area. Additionally, the router features five Ethernet LAN (RJ-45) ports, enabling users to connect multiple wired devices simultaneously. The Linksys Max-Stream AC2200 wireless router is equipped with Tri-Band technology, making it ideal for 4K and HD video streaming as well as next-gen online gaming. Households with heavy Wi-Fi usage will benefit from its combined speed of 2.2Gbps and Quad-Core CPU, ensuring fast data transfers. ASUS offers the 3-in-1 RT-N12 router, which functions as a Router, Access Point, and Range Extender. With a wireless N speed of 300Mbps, it caters to small businesses and home offices, providing both wired and wireless network connections. Securifi Almond stands out as the world's first wireless N touchscreen router. It boasts a throughput of 300Mbps, the latest WPA/WPA2 Security, and superior range, making it a reliable choice for users seeking advanced features and convenience. Networking 101 Interference -non-physical factors -caused by other radio signals -may cause sudden disconnection, slow speed, delayed responses, buffering/audio skips Example devices: -bluetooth speakers/headsets -remote (infrared) -cordless telephones -cellphones -wireless mouse and keyboards -baby monitors -microwave oven -other wifi routers Obstructions -physical factors that affect wireless connections -block signals if positioned in between devices Examples: -walls concrete or bricks -mirrors -metals -water -chicken wire How do we deal with them? -move it to a diffrent place if mobile -move router to better spot -use 5Ghz instead of 2.4Ghz -change channels -turn off devices which causes interference -get a wifi extender Networking VOICE Vertical - antenna must be pointed vertically for maximum coverage Obstructions - physical barriers that affects the signal quality received by devices Interference - different radio frequencies that interferes with the signal Central - modem or router must be placed in a central location so wifi coverage is even Elevated - modem or router must be placed in an elevated area for better coverage Internet Connection Risks for Standard House with basement and attic 1. Distance from the Router: - Risk: The farther your basement or attic is from the router, the weaker the Wi-Fi signal becomes. Walls, floors, and other obstacles can significantly reduce signal strength. - Solution: Consider moving the router to a more central location in your home. Placing it on the main floor can help distribute the signal better. 2. Signal Interference: - Risk: Other electronic devices (such as microwaves, cordless phones, and baby monitors) can interfere with your Wi-Fi signal. - Solution: - Move Electronics Away: Keep other devices at least six feet away from your router. - Change Wi-Fi Channel: Access your router settings and switch to a less congested Wi-Fi channel to minimize interference⁷. 3. Placement in Basement or Attic: - Risk: Placing the router in the basement or attic can weaken the Wi-Fi signal. - Solution: - Avoid Exterior Walls: If you must place the router in the basement, avoid using a shelf on the exterior foundation wall. - Central Location: Opt for a central location within your home to improve coverage³. 4. Use Ethernet Cable (Wired Connection): - Risk: Relying solely on Wi-Fi may lead to weaker signals in certain areas. - Solution: Consider using an ethernet cable (Cat 6 or higher) to directly connect devices in the basement or attic. Wired connections often provide faster and more stable internet speeds². 5. Wi-Fi Range Extenders or Mesh Systems: - Risk: Without proper coverage, you may experience dead zones in the basement or attic. - Solution: - Wi-Fi Extenders: Install Wi-Fi range extenders strategically to boost the signal in areas with weak coverage. - Mesh Wi-Fi Systems: Consider a mesh system with multiple access points (nodes) placed throughout your home. This ensures consistent coverage, even in basements and attics⁴. 6. Check Construction Materials: - Risk: Thick walls, metal structures, or dense materials can obstruct Wi-Fi signals. - Solution: If possible, position the router away from thick walls or use additional access points to penetrate these barriers⁹. Remember that optimizing Wi-Fi coverage involves a combination of placement, hardware choices, and interference management. Experiment with different solutions to find what works best for your specific home configuration! Techies and Non-Techies Non-Techie -don't know what to do -cable cannot connect to server -don't know what internet cable is Agent: -asking for some technical terms -verification of lights in modem -step-by-step guides Techie -the customer's voice is somewhat unclear, fast and says too much additional information -concern is about upload/download -she knows that there is something wrong with the internet speed -asks lots of follow-up questions about the package they have -asking the connection of their internet speed and their package -knows about satellite internet -gives advice or somewhat corrects the agent Agent: -asks for her account and verify it -giving the speed test result -speaking while customer is not yet finished talking -run again diagnostics about checking the alignment of modem Steps to communicate tech concepts to non-techie -know your customer -do not assume -let me know if you don't know something about this -no acronyms, jargons, buzzwords -simplify instructions -be descriptive -listen and observe your customer -listen to hints, words and terms -listen to verbal and non-verbal cues -capture hesitations like "uhms" -connect with customers -break down initial tension -smile at the beginning of the call -use humor if needed -use reassuring phrases -this won't be complicated, I promise you Hughes Technical Terms for the Day -Latency - form of delay before the transferring of data begins following a command for it's transfer. -Upload and Download - upload is the act of sending data from your device to the internet, while download is the act of receiving data from the internet on your device. -Ping - a command sent to a host that requires a response. Used to check if host is available and how long the response takes. Next Words 1. ATA 2. HD/HIgh Def/4K 3.
