The lease time is a good trick.
Other approaches. Many routers (not all) have the ability to associate an IP address to a devices MAC address (Media Access Control Address - this is the nn.nn.nn.nn.nn.nn address associated with the WiFi or Ethernet adaptor). This is part of the router's DHCP configuration.
You can give your Macs a fixed IP address via System Preferences -> Network -> WiFi -> Advanced -> TCP/IP. The address you would pick would be based on the DHCP assigned address you currently have. eg 192.168.1.n, or 10.0.1.n, etc... You would check your Router to see what the max DHCP assigned address is (or just set it to a new max address), then start assigning fixed IP address above the DHCP range. For example if the DHCP range is 192.168.1.1 to 200, you would start setting your Macs to 192.168.1.201, 202, 203, etc.. There are similar network setups for iPads, iPhones, etc...
HOWEVER, when assigning a fixed IP address to a laptop, this makes it difficult for the laptop to leave the building, as the rest of the world is still using DHCP and you cannot just walk into their building an expect your fixed IP address to work. Macs have the ability to have separate locations that you can configure and manually change, but it is a pain. System Preferences -> Network -> WiFi -> Location
I know this is an old thread but this response is the closest to the information I am looking for.
My iPad drops the wifi connection when the ip renewal lease expires. I have found online that the fix is to assign a statuc ip address to the iPad based on its MAC address. How do I do this?
I know how to get the iPad to connect using a static ip using this screen
And I know how to choose an ip address outside my router's dhcp range. But how do I find out what the other values should be for the above page?
I'm going to try to revive this old thread. I've read dozens of other posts regarding creating static IP addresses and I'm still confused.
Here's my situation... I am using an IP remote control called Roomie to control all of the devices in my home theater system as well as a couple Sonos speakers, the iTunes account on my iMac, lights, AC, etc.
The trouble I'm having is that the IP addresses for things like my TV, surround sound receiver, blu-ray player, etc, keep changing, and the remote control software loses its ability to control that device until it figures out the new IP address.
My ISP is Comast. My modem is a Motorola Surfboard. My router is a latest gen Airport Extreme. The router feeds an ethernet switch which further feeds a Netgear Powerline 500 transmitter. A Powerline 500 receiver is located near my home theater and it feeds a second ethernet switch which connects all of my devices to the network.
Everything shows up fine on the network and I have complete control over everything... until IP's change.
The home theater consists of a Samsung UN60F8000 Smart TV, Yamaha IP controllable receiver (RX-A1010), Oppo 103D blue-ray player and a 2nd generation Apple TV. Elsewhere in the house I have a Sonos Play 1 and a Sonos Play 3. I would like to assign static IP addresses to:
Sonos Play 1
Sonos Play 3
Can you (or anyone else) provide a step-by-step? Networking is not my forte and my command of Airport Utility is limited.
Thanks in advance,
