What is the difference between a modem and a router?

A modem creates a serial link between two computers over some sort of long distance media. It operates at the data link layer. A router makes forwarding decisions between logical networks. It does not need to take account of the framing and transmission details—those are the responsibility of the modem (or of an Ethernet switch or wireless access point). It just needs to know that a particular logical network can be reached over one of its interfaces. Most SOHO devices pack all these functions into a single appliance but it is important to appreciate the differences between the functions.

What does attenuation mean?

Attenuation describes the loss of strength of a signal the farther it has to travel. Attenuation sets the distance limitations on different network media types.

What is the latest Wi-Fi standard and which frequency band(s) does it use?
