Fix: Samsung Galaxy S23 Won’t Connect to Wi-Fi Network

While the S23 series was a massive upgrade thanks to the new internals and nailing the overall balance, the battery life and efficiency see a major bump even on the smallest model thanks to the Snapdragon 8 Gen 2 SOC. However, the S23 isn’t free of issues. There are a lot of complaints on the Samsung forums their S23 devices are unable to connect to Wi-Fi.

The first type of issue is prevalent with the S23 series, with Wi-Fi 6. The S23 series has a Wi-Fi disconnection issue with Wi-Fi 6. If you have a compatible Wi-Fi 6 router at home and use your phone with a Wi-Fi 6 network, you can temporarily solve this problem until Samsung rolls out a fix.

You can disable Wi-Fi 6 from your router’s WLAN settings to see if this helps. It’s typically under the advanced settings menu of many ISPs. It’s not an issue on all units, but many people still face problems with Wi-Fi 6. There’s little real-life difference, so you can try disabling it to check if it helps.

It’s understandably frustrating to see so many problems on modern flagships. The phone sometimes randomly switches to mobile data despite Wi-Fi working perfectly fine. This is another common issue. In other cases, the phone refuses to connect to the Wi-Fi network. In this article, we’ll show you how to address this problem.


How to Fix S23 Wi-Fi Issues?

Fix 1: Register the Wi-Fi again

Note: Before trying this, you can manually forget the Wi-Fi network and re-enter the Wi-Fi password to reconnect. Check if that helps first.

  1. Open the Settings app and tap on General Management.
  2. Tap on the Reset submenu.
  3. Here, tap on Reset network settings. Tap on reset and confirm.
  4. Once complete, visit the Wi-Fi page and re-register the network. You have to enter your password again.

Fix 2: Soft reset your phone

This step clears all cache and RAM; any faulty cache memory will be cleared.

  1. Hold your device’s power and volume buttons down for around 10 or 15 seconds until the phone restarts.
  2. Forget your Wi-Fi network.
  3. Re-enter the passcode and connect.

Fix 3: Check your Wi-Fi Settings

  1. Open the Settings app and verify if you have airplane mode turned on. Toggle the switch off since Airplane mode disables Wi-Fi.
  2. Ensure Wi-Fi is turned on and displays a blue indicator in the quick toggles.
  3. Turn off power saving mode. In some cases, this may restrict the bandwidth of your router.
  4. Ensure you’re using a Wi-Fi 5 network since Wi-Fi 6 is still buggy on the S23 series.

Fix 4: Verify if your internet is working

If you have a personal computer or another phone, try connecting your Wi-Fi to that phone. If it works, then proceed to Fix 5. If it doesn’t work, there’s probably an issue with the cables or your router. Unplug and reconnect the cables, and turn the Wi-Fi router on again. You may get your router checked for problems too.

Try contacting your ISP and asking them to perform the routine checks. You can try flushing the DNS Cache and resetting the configurations from your ISP’s configuration page. Now, try reconnecting your S23 to Wi-Fi.

Fix 5: Contact a service center

If none of the fixes work, there’s a potential hardware defect with your phone. It could be a faulty Wi-Fi chip. Contact Samsung service and report these problems to them. While Samsung will mostly replace the chip for free, there’s a chance they might charge you in case of severe chip issues. Samsung will also try re-flashing the software package onto your device at the service center.
