Computer Hacking Forensic Investigator (CHFI v10) — Question 495

Tyler is setting up a wireless network for his business that he runs out of his home. He has followed all the directions from the ISP as well as the wireless router manual. He does not have any encryption set and the SSID is being broadcast. On his laptop, he can pick up the wireless signal for short periods of time, but then the connection drops and the signal goes away.
Eventually the wireless signal shows back up, but drops intermittently. What could be Tyler issue with his home wireless network?

Answer options

• A. Computers on his wired network
• B. Satellite television
• C. 2.4Ghz Cordless phones
• D. CB radio

Correct answer: C

Explanation

The correct answer is C, as 2.4Ghz cordless phones operate on the same frequency band as many wireless networks, which can cause interference and result in dropped connections. Options A and B are less likely to directly interfere with the wireless signal, and D, while it can cause some interference, is not as common in residential settings compared to cordless phones.
