When evaluating which statement about wireless networks is not true, it helps to consider common characteristics of wireless LANs vs. wired LANs.
Option 1: 'it is less trouble to install' This is often cited as an advantage of wireless networks because you don't need to pull cables to each device, set up switches in ceilings, or run conduits. However, some environments require careful planning for interference, security, and coverage, so the installation can still be nontrivial. Overall, it is generally true that wireless can be less trouble to install than wiring a full wired network, though not universally.
Option 2: 'it is convenient for users that work in many locations' This is a well-known strength of wireless: mobility. Users can connect from different rooms or buildings without reconnecting cables, so this statement is true.
Option 3: 'computers at the nodes can run different operating systems' Wireless networks are agnostic to the OS on each node; the network communicates using standard protocols (e.g., Wi-Fi) and supports diverse OS choices. Thus this statement is true.
Option 4: 'it is generally faster than wired LAN' This is the statement that is not generally true. Wired LANs (e.g., Ethernet with appropriate standards) typically offer higher and more consistent bandwidth and lower latency than wireless, though wireless speeds have improved. In many cases, wired connections outperform wireless, so this claim is false in the general case.

In summary, the first three options describe typical advantages or neutral traits of wireless networks, while the fourth option makes a claim about speed that is not generally correct. The incorrect statement is the final option.
