You work for a small enterprise that has three on-premises servers and a shared private network. You can connect a new laptop to the company's wireless access point, but the laptop has no network or internet connectivity. The servers on the same network are operating normally, and you know those servers use static IP addresses. Based on this information, where should you start troubleshooting first?
Verify that the DHCP service is functioning properly
Check for radio-frequency interference on the wireless channel
Connect to the 5 GHz band instead of the 2.4 GHz band
Disable the firewall that separates the Wi-Fi and VLAN networks
Because the existing servers use static addresses while the new laptop is expected to obtain its settings automatically, the most likely reason for having a Wi-Fi connection but no network access is that the laptop did not receive a valid IP configuration. Dynamic Host Configuration Protocol (DHCP) assigns IP addresses and other parameters to clients; therefore, verifying that the DHCP service or scope is functioning and issuing leases is the logical first step. Firewall issues or RF interference would not prevent the client from getting any IP address at all.
