I don’t have an airport extreme but this should work regardless…
on your mac, open network preferences from either the icons on the right of top menu bar or click on system preferences and then click on network.
from the connected ethernet or wi-fi information write down the following, the IP, subnet mask, router, dns server (more then one separated by a coma). You will need most of this information to type into your Cloud device. When you are done, close this.
in safari, bring up the dashboard of your cloud
go to setting, then select Network
you should see Network Profile
now be very careful here as users have known to enter improper info and the device no longer responds since they don’t know the ip. but lets get started.
a) click on static under Network Services
b) click on details…
ip address should be whatever the first 3 set of numbers from the ip that you wrote down from your mac
so something like 192.168.0.xxx <= this last number should be something like 190 or 150 but less then 240 (thereabouts)
remember this ip number because it is your new Dashboard IP number from now on.
Netmask = usually 255.255.255.0
gateway = 192.168.0.1
dns server 1 = from your Mac
dns server 2 = from your Mac
- replace your dashboard number with the new ip on the safari URL
Check your time date
settings / General
Time Zone, and make sure NTP service is ON.
Check with your Router to see what is your range of numbers for DHCP. Usually this is something like Starting IP Address and the other setting is Maximum number of DHCP Users. So starting can be 192.168.0.10 and max is 100. or ending can be 192.168.0.110
You might also see Client Lease Time, so try setting that to 7200 minutes which is 5 days. (max on mine)
