IP Address keeps Changing

The IP address keeps changing and the app on the phone disconnects frequently from the device. Need to look at the face of the controller to re-verify which IP address it's on everytime it disconnects. Also cannot get to the HF main page on my computer unless I reverify the IP address. Can it be fixed or is there another way to make it static on the router? Thanks in advance for the advice.

You can easily set a Fixed IP address via the Network Setting / Wireless Settings page via the Web interface.
Click the TCP/IP link at the top of the the Wireless Settings page.

You can then disable DHCP and set a fixed IP address for your HF device. Be sure you enter the information correctly including DNS fields.

Typically you would configure your router DHCP settings to hand out addresses at a starting point and ending point that reserves other addresses for Fixed IP assignment.

For example: Set your Router to start handing out IP addresses at and limit the number of addresses to say 50.
Then you can assign the addresses from through and through to individual devices like HydroFLASH etc.

Once set HF will always be accessible via that address.

Hope this helps.

Another approach: Most routers have an option to assign a "static" DHCP IP address to a device based on its MAC address. This is my favorite approach. That way, the HF will always get an IP that will not conflict with anything else on the network, and it does it through DHCP, so you do not have to manually deal with all the IP address info.

Thanks. I fixed the IP at the HF device. Not really a network guy so a bit gunshy about the other suggestions. Everytime I mess with the router bad things happen. Appears to be working just fine on one IP. Thanks.
