This post will answer questions or address problems related to Samsung Galaxy S4 WiFi connectivity. While only one email message will be shown here, we have already received tons of questions related to it. Here is the actual email from one of our readers:

I have internet service through my home phone AT&T. I have a wireless modem. I have to enter my password every time I leave my home and return.  The phone detects the modem but I am required to enter the password. Why doesn’t the Galaxy S4 remember/save the password? Is there a setting to fix this? 

Another issue is my WiFi will be off and I have not turned it off. If I’m in an area that does not have WiFi, is there a setting that causes the WiFi to turn off?”

Basically, there are two problems here:

  1. Galaxy S4 always asks for WiFi network password every time the owner tries to connect.
  2. The WiFi automatically turns itself off. (The owner didn’t specify whether the disconnection problem happens while the phone was in use or not.)

Why doesn’t the Galaxy S4 remember/save the password? Is there a setting to fix this?

Yes, there is a fix to it. It’s actually just a matter of ticking a checkbox so the device would automatically connect to a trusted / saved network. Here’s how to do it:

  1. From the Home screen, tap the Menu key.
  2. Tap Settings then touch the Connections tab.
  3. Tap WiFi, then tap the Menu key again.
  4. Touch Advanced.
  5. Tick the option Auto Connect.

The Auto Connect option allows your device to automatically connect to a saved network whenever the phone is within range.

Another issue is my WiFi will be off and I have not turned it off.

Due to the power-saving features of the Galaxy S4, WiFi will be turned off the moment the phone goes to sleep or becomes idle for several minutes. But you can set the device to continue connecting to the network while other processes are being stopped. Here’s how…

  1. From the Home screen, tap the Menu key.
  2. Tap Settings then touch the Connections tab.
  3. Tap WiFi, then tap the Menu key again.
  4. Touch Advanced.
  5. Tap the option Keep WiFi On During Sleep.
  6. Tick Always.

This is just one angle of solving the problem. Let’s try to look at it from another angle; this time, let’s dwell on the network problem.

Modems and routers needed to be refreshed from time to time. When is the last time you power-cycled your modem? If you can’t remember when, then today may be the best time to do it.

  1. Unplug your modem (then the router if you have one).
  2. Let it rest for a minute.
  3. Plug your modem again (it may take 30 seconds or a minute before the modem can boot up).
  4. In your phone, go to WiFi settings and forget your network.
  5. Let the phone detect your network again and connect.
