How to Set Manual DHCP and a Static IP Address on an iPad or iPhone
Certain Wi-Fi networks require clients to use static IP addresses or manual DHCP information in order for a device to connect properly, setting either of these is easy within iOS.
- Tap on “Settings” and then tap on “General”
- Tap “Wi-Fi” and look for the network name you are connected to, tap the blue (>) arrow next to it
- Tap the “Static” tab and enter network appropriate DHCP/static IP information
- Close out of Settings and launch Safari or another network app to confirm connectivity
Settings are applied automatically after all the information is typed in, if you need an easy to remember DNS try using Google’s 126.96.36.199 server, which is fast, efficient, and has very high reliability.
I’ve had to set manual DHCP information in order to connect iPads to certain older Wi-Fi networks on more than one occasion, something I’ve encountered in Mac OS X Lion before as well. This makes setting a static IP a fairly reliable network troubleshooting trick when certain iOS devices are having problems with very specific routers and networks, since sometimes the problem is either a conflict with another IP, or just an issue with how certain router firmware behaves with iOS.
The screenshot above demonstrates this used on an iPad, but the method is the same on an iPhone and iPod touch as well.
