Saved IP Addresses being forgotten

[joebro391]

Hello All,

I have a Samsung Tab A (2020) that I use to connect to a series of custom deployed systems via WiFi. Each deployed system has its own WiFi module that acts as an Access Point for the tablet to connect to. When connecting to a deployed device for the first time, I go to the WiFi menus on the tablet and click on "Add Network", add a name, then set the IP Setting to static, manually enter the IP address, gateway, etc... I am then able to connect to the device and communicate properly.

The issues arrises when I disconnect from a deployed system and then later attempt to reconnect to it. The tablet will always automatically connect to whichever added device's signal strength is strongest. If I attempt to connect to the device by clicking on it in the WiFi networks list, the tablet seemingly clears the IP address and I am unable to connect to my deployed device. When that happens, I need to manually re-enter all of the WiFi information for that particular deployed system. This does not happen when I am reconnecting to a normal network router.

My question is: Is there a setting in Android to prevent this wiping of the IP addresses when I press them?

Best,
Joe

Welcome to AC!
On your tablet under WiFi>upper right corner tap>tap intelligent Wi-Fi do u see these options? Can toggle off switch to better WiFi signal

The IP address is ultimately decided by the host device (router, for example) not the client device(a phone, for example). If you really want a static IP you would have to set this up in the host not your phone.

Thank you so much for your reply. I do not seem to have "intelligent WiFi" as a setting on this tablet. I just double-checked the firmware version to confirm my claim. Was intelligent WiFi added on a later Android Version?

Sure, I believe I understand what you're saying, however, while setting the WiFi setting to "static" on the tablet might be moot, it's still the tablet that's forgetting the IP address. And that's what I want to prevent

The network changes its IP address. The tablet isn't forgetting anything. The tablet just doesn't know to connect to a different IP address when it changes.

The network is changing which IP address? The tablet? Does it matter if the tablet's IP address is changing?

The tablet is forgetting the IP address of the AP that we had manually entered when we click on the device that we wish to reconnect to.

The IP of the device we're connecting to does NOT change. Remember, the tablet is connecting to a WiFi module that is in an AP mode. The device we're connecting to has a static IP (it's actually a address range, something like .20/255 iirc. That may or may not be important). The WiFi module is connected to a controller board that allows us to issue GPIO commands from the tablet via a proprietary App.

I'm not sure about tablets but on the phone it has been awhile

On phones intelligent WiFi is found by tapping the 3 dots on the WiFi in settings.

What if you set the name and password on all access points to be the same as on your router? https://www.windowscentral.com/whats-difference-between-access-point-ap-mode-and-router-mode

Can't do that as these systems can be deployed in public areas near open, public WiFi :/
