Final answer:
To correct the problem, check if the DHCP server is functional and ensure that the default gateway device is working properly. Checking the connection of the DNS server to the Internet may also be necessary.
Step-by-step explanation:
To correct the problem of customer mobile devices not receiving network configuration information, the first step would be to check if the DHCP server is functional. The DHCP server is responsible for assigning IP addresses and network configuration details to devices on a network. If the DHCP server is not working properly, customer devices will not be able to receive the necessary information to connect to the wireless network.
Additionally, it is important to ensure that the default gateway device is working properly. The default gateway device is responsible for routing network traffic between different networks. If the default gateway device is not functioning correctly, it could be preventing customer devices from accessing the Internet.
Checking the connection of the DNS server to the Internet might also be necessary, as the DNS server is responsible for resolving domain names to IP addresses. If the DNS server is not connected to the Internet, customer devices may not be able to access websites by their domain names.
