- Turn on the other devices on the network.
- With Obtain IP Address set to Manual, compare the IP address, subnet mask and default gateway on the report with your network and fix any that are wrong.
- With DHCP enabled, set Obtain IP Address to Auto. To use the DHCP address as a static one, set Manual, enter the IP address from the report and use the subnet mask 255.255.255.0.
- If it still does not connect, switch the router or access point off, wait about 10 seconds and on again.
