5 Wireless Network Design and Configuration Free Online FlashCards

What does an SSID identify, and what does it not provide?

An SSID is the network name clients see; it is not itself a security control.

Which security mode suits a home WLAN using a shared password?

WPA3-Personal is preferred for a home or small shared-password network. Use a strong, unique passphrase.

How does WPA3-Enterprise authenticate organizational users?

WPA3-Enterprise uses 802.1X with a RADIUS authentication server to support individual organizational accounts.

Which 2.4 GHz channels form a typical non-overlapping 20 MHz plan in the United States?

In a typical United States 20 MHz plan, channels 1, 6, and 11 do not overlap. Legally available channels vary by country.

What is a coverage tradeoff of 5 GHz compared with 2.4 GHz?

5 GHz generally offers more channel choices and less congestion than 2.4 GHz, but walls and other obstacles can reduce its reach.

What equipment can use 6 GHz Wi-Fi, where permitted?

6 GHz is available to compatible Wi-Fi 6E and newer equipment where permitted. Clients must support the band, and coverage through obstacles can be more limited.

What channel-planning tradeoff comes with wider Wi-Fi channels?

Wider channels can raise peak data rates but use more spectrum and leave fewer separate channels for nearby APs. In busy environments, narrower channels can improve channel reuse.

Where should an access point generally be placed for useful coverage?

Place APs near users, usually in open, central locations. Avoid hiding them behind metal, inside cabinets, or near radio-interference sources.

Why might a strong Wi-Fi signal still perform poorly?

A strong signal does not guarantee good performance; client load, same-channel overlap, interference, or a slow wired uplink can still cause problems.

Why can adding access points without a channel plan hurt performance?

Adding APs without planning can increase congestion. Spread nearby APs across available channels; in 2.4 GHz, reuse channels 1, 6, and 11.

What should a client verify about an enterprise Wi-Fi authentication certificate?

For enterprise Wi-Fi, confirm that the client trusts the organization’s authentication server certificate; do not blindly accept unexpected certificate prompts.

What should you check first if a Wi-Fi network is not visible?

Check that Wi-Fi is enabled, the AP is broadcasting, and the client supports the configured band and channel.
