1. Connect the iMac to the router. Make sure that your computers’ operating systems are up to date and that your router has the latest firmware.
Router:
2. Reset your router to its defaults.
3. DO NOT attempt to “Clone MAC Address”.
4. Enable static DHCP and assign your iMac the following static IP address: 192.168.0.100.
5. Under DHCP Server, change the “Starting IP Address” to 192.168.1.101.
6. Leave all other router settings AS IS for now.
iMac:
7. Open System Preferences: Network: TCP/IP
8. While “Configure IPv4” is set to DHCP, record the DNS Servers addresses.
9. Now make the following adjustments:
Configure IPv4: Manually
IP Address: 192.168.0.100
Subnet Mask: 255.255.255.0
Router: 192.168.0.1
DNS Servers: (Enter the addresses you recorded in step 8)
At this point, your iMac should have a static address to the Internet. Try connecting the laptop wirelessly using DHCP. If everything works, feel free to adjust encryption settings, etc.
EDIT: I should've told you to hook up your iMac to the router
before telling you to make changes to the latter. Doh!
