Exam 220-1101 topic 1 question 465 discussion

The user has a legacy computer hence probably the WLAN card (Wireless LAN card in their laptop) cannot communicate using the new access point since its either an encryption issue (ie the Access Point is using WPA2 and the WLAN does not understand it). The best thing to do here is to purchase a new USB adapter that supports the newer protocols and would connect to the access point using the USB adapter.

A USB adapter is a device that can plug into a USB port on a laptop and provide wireless connectivity to a network. A USB adapter can support different wireless standards, such as 802.11a, 802.11b, 802.11g, 802.11 n, or 802.11ac. A USB adapter can also support different wireless frequencies, such as 2.4 GHz or 5 GHz. In this case, the user with an older laptop may not be able to connect to the office network after new access points were installed because the laptop’s built-in wireless card does not support the same wireless standard or frequency as the new access points. For example, if the new access points use 802.11ac and 5 GHz, and the laptop’s wireless card only supports 802.11g and 2.4 GHz, the laptop will not be able to communicate with the access points.
