Asking the user to confirm the exact Service Set Identifier (SSID) they are trying to connect to is the best next step. This is crucial because the user may be attempting to connect to the wrong network due to a typing error or selecting the wrong SSID from a list of available networks. Confirming the SSID will help in identifying whether the user is selecting the designated SSID for the company's network. Checking if the SSID is visible only addresses whether the network can be seen, not if the user is connecting to the correct one. Restarting the user's wireless adapter or checking the DHCP server would be steps to consider after verifying the user is attempting to connect to the correct network.
