Your laptop shows the WiFi icon with one bar (weak signal) and a video keeps buffering. What is the most likely cause and best first step?
AThe internet is down worldwide — call your ISP immediately
BYour laptop is broken and needs repair
CYour device is far from the router or walls are blocking the signal — move closer to the router
DYou need to create a new account with your internet provider
One bar of WiFi signal means weak connection — most likely because the device is far from the router or obstacles are attenuating the signal. Moving closer to the router is the simplest and most likely fix. Calling the ISP (option A) or assuming hardware failure (option B) would only be appropriate after basic troubleshooting — signal strength and proximity checks — has failed.
Question 2 Multiple Choice
What role does an Internet Service Provider (ISP) play in getting your computer onto the internet?
AThe ISP is the same thing as the WiFi router in your house
BThe ISP provides the connection from your home network to the broader internet
CThe ISP creates the WiFi password for your home network
DThe ISP is only needed for wired connections, not WiFi
Your home router creates a local network among your devices, but it connects to the outside internet through your ISP — the company you pay for internet service. Without an ISP, your router could network devices in your home but couldn't reach websites, email servers, or anything outside. The ISP provides the link between your home and the global internet, regardless of whether you use WiFi or a wired connection.
Question 3 True / False
A wired (Ethernet) connection is generally more reliable than WiFi because it doesn't depend on radio signal strength.
TTrue
FFalse
Answer: True
Wired connections transmit data through a physical cable, eliminating the variables that degrade WiFi signals: distance from the router, walls and obstructions, interference from other wireless devices. WiFi is more convenient because you can move freely, but for activities requiring a stable connection — video calls, large downloads, gaming — wired is preferred.
Question 4 True / False
When your internet stops working, the first step should be to call your ISP.
TTrue
FFalse
Answer: False
Most internet problems are local and easily fixed before involving the ISP. The correct troubleshooting order is: (1) check that WiFi is turned on, (2) confirm you're connected to the right network, (3) restart the router. Only if all local steps fail — and other devices in your home also can't connect — does calling the ISP make sense. Starting there skips faster solutions.
Question 5 Short Answer
What is the difference between a WiFi router and an ISP, and why do you need both to access the internet?
Think about your answer, then reveal below.
Model answer: The WiFi router creates your local network — it broadcasts the wireless signal your devices connect to and manages traffic among them. The ISP (Internet Service Provider) connects your home network to the broader internet. Without the router, your devices can't connect to the local network wirelessly. Without the ISP, your router can't reach websites or services outside your home. You need both.
Understanding this distinction helps with troubleshooting. If devices can see the router but pages won't load, the problem is likely with the ISP connection. If devices can't even connect to the router, the problem is local. Knowing which layer is broken focuses the fix.
