Is the problem with a weak Wi-Fi signal on smartphones? Samsung It happens more often than you might think, and the router isn't always to blame.

In this article we will analyze reasons for poor Wi-Fi reception on phones Samsung (including models Galaxy S24, Galaxy Z Flip5 and budget series Galaxy M/J), and also 10 Proven Ways to Boost Your Signal — from basic settings to hidden functions Android 14Don't bother rushing out to buy a new router: in 80% of cases, the problem can be resolved with software or minor hardware adjustments.

Important: If you have Samsung older than 2018 (for example, Galaxy S8 or Galaxy Note 9), some of the tips may not work due to an outdated Wi-Fi module. In this case, please refer to the section about alternative solutions.

1. Check the basic Wi-Fi settings on your phone

The first thing to do is eliminate the "human factor." Users often disable key features without even realizing it. Go to Settings → Connections → Wi-Fi and run the check:

• 🔄 Update the list of networks: Tap the three dots in the upper right corner and select "Refresh." Sometimes the phone "forgets" available networks.
• 📶 Check your connected network: The phone may have automatically switched to nearby access points with a weak signal (for example, _ext or _5G from your router).
• 🔒 Make sure the password is entered correctly.: Even one extra period or space can cause constant connection breaks.

If your Samsung I'm connected to the network, but the internet isn't working, try forget the network and reconnect:

Critical detail for Samsung: If your router supports Wi-Fi 6 (802.11ax), but the phone doesn't see it, update the router firmware. Many models Galaxy (For example, S21+ or Note 20) require the latest version of software to work correctly with Wi-Fi 6.

3. Choose the right frequency: 2.4 GHz vs. 5 GHz

Phones Samsung They automatically connect to the network with the "best" signal, but this isn't always optimal. Here's how to select a frequency manually:

• 📡 2.4 GHz: Better through walls, but susceptible to interference from microwaves, Bluetooth devices, and neighboring networks. Suitable for distant rooms.
• 🚀 5 GHz: Higher speed and stability, but less effective at penetrating obstacles. Ideal for streaming video and gaming near the router.

To manually select a frequency on Samsung:

2. Tap on your network name and select "Change network."
3. Activate the "Advanced" option and find the "Frequency" (or "Band") item.
4. Select 5 GHz for speed or 2.4 GHz for range.

How do I know what frequency my Samsung supports?

Models Galaxy S10 and newer support both frequencies. To check:

1. Go to Settings → About phone → Software information.

2. Look at the line “Kernel version” - if there is a mention ac or ax, then 5 GHz is supported.

3. For accurate information, enter in Google request: "[phone model] Wi-Fi specifications".

⚠️ Attention: some budget models Samsung (For example, Galaxy A03s or Galaxy M12) do not support 5 GHzIn this case, all that remains is to optimize 2.4 GHz or consider purchasing a signal repeater.

Also check if the mode is turned on Ultra Power Saving (in some models Samsung (It completely disables Wi-Fi). To do this:

1. Swipe down the notification panel.
2. Make sure the Energy Saver icon is not active.

6. Change DNS and check for IP conflicts

Sometimes the problem is not the signal strength, but incorrect network settingsFor example, if the router assigns the phone an IP address that's already taken by another device, the connection will constantly drop. To check this:

• 🔢 Change DNS: By default, the provider's DNS is used, which can slow down. Try Google DNS (8.8.8.8 And 8.8.4.4) or Cloudflare (1.1.1.1):
  1. Go to Settings → Connections → Wi-Fi.
  2. Tap your network → “Change network” → “Advanced”.
