Question

Users are contacting the internal helpdesk, stating that they are having difficulty staying connected to the wireless network. When the technician investigates, it is discovered that the users are having a problem using the wireless network in the company break rooms. Which of the following should the technician do FIRST?

Options

  • BRemount the access points to a place on the ceiling closer to the break rooms.
  • CUnplug appliances (e.g. microwaves) to see if they are causing interference.
  • DChange the encryption on the access points from WPA2 to WEP.

Explanation

Wireless connectivity problems isolated to break rooms strongly suggest radio frequency (RF) interference from household appliances. Microwave ovens operate on the 2.4 GHz frequency band - the same band used by 802.11b/g/n Wi-Fi. The FIRST troubleshooting step should always be to identify the root cause before making changes. Unplugging microwaves and other appliances is a quick, non-invasive diagnostic test to confirm interference before committing to hardware changes or configuration updates. Installing new APs or remounting existing ones would be premature without confirming the cause first.
