Question
You are working as a wireless networking technician and have been sent to a user’s home to install a brand new 802.11ac wireless access point to replace their old access point. To ensure all of the current devices on the network will automatically connect to the new network, you set the SSID, encryption type, and password to the same ones as the existing access point. You turn the new access point on and notice most of the devices connect automatically, but one older wireless printer won’t connect. You notice that the printer is about 7 years old, but the user says it has always worked great over the old wireless network.
What is the MOST likely reason that the printer will not connect to the new access point?

Explanation
Correct Answer: C. The access point and the wireless printer have a frequency mismatch
- The new 802.11ac wireless access point operates exclusively on the 5 GHz frequency band for higher performance and faster speeds. Older devices, like the 7-year-old printer, may only support the 2.4 GHz frequency band (commonly used by legacy standards like 802.11b/g/n). This frequency mismatch prevents the printer from connecting to the new access point.
Why the other options are incorrect:
-
The transmit power on the access point is too low:
- Transmit power affects the range of the wireless signal. If most devices connect without issue, this is unlikely to be the problem. Additionally, the printer is not described as being far from the access point.
-
The incorrect channel is configured on the access point:
- Modern access points typically use auto channel selection, and mismatched channels would not prevent devices from connecting entirely. It would more likely cause interference or degraded performance.
-
The wireless printer is configured with the wrong password:
- The scenario states that the SSID, encryption type, and password were configured to match the old access point. If the password were incorrect, the printer would prompt for the correct password rather than fail to connect entirely.
