"Connecting when Wi-Fi signal improves": What it means and how to troubleshoot network issues

Have you ever seen a notification on your smartphone, laptop or TV that says "connection when the Wi-Fi signal improves"? This message may appear unexpectedly—for example, when you're trying to connect to a network but your device gets stuck during the connection quality check. Most often, it indicates that your device is attempting to automatically switch to a more stable channel or access point but is encountering obstacles, such as a weak signal, interference, or incorrect router settings.

In this article we will take a detailed look at Why does this notification appear?, the technical processes behind it, and what to do if the device gets stuck during the signal improvement phase. You'll learn how to diagnose the problem, configure the router for stable operation, and avoid similar situations in the future. We'll pay special attention to modern Wi-Fi 6/6E standards, dual-band networks and the specifics of connecting smart devices (TV, IoT gadgets).

If you are experiencing this issue on a specific device - Android, iPhone, Smart TV or laptop — the article includes a section with step-by-step instructions for each platform. We've also compiled answers to frequently asked questions, from the differences between 2.4 GHz and 5 GHz to the impact of neighboring networks on connection quality.

What does the message "connecting when Wi-Fi signal improves" mean?

This notification appears when the device detects an available Wi-Fi network, but it can't immediately connect to it at an acceptable level of quality. Instead, it starts a process connection optimization, which may include:

• 🔄 Automatic search for the best channel (if the router supports DFS or Auto Channel Selection).
• 📶 Switching between ranges (from 2.4 GHz to 5 GHz or vice versa).
• 🔗 Re-authentication (if the previous session was interrupted).
• ⚡ Speed ​​and latency check (on some devices, for example, Samsung Smart TV).

Ideally, this process takes a few seconds, and you won't even notice it. However, if the network is configured incorrectly or there is external interference, the device may "freeze" at this stage, displaying a connection notification. endlessly or with errors.

For example, on Android-in devices this is often associated with the function Wi-Fi Assistant (in Google services), which tries to connect to the "best" network, even if the current one is working stably. iPhone the option plays a similar role Auto-Join in the Wi-Fi settings.

Reasons for the notification: technical and external factors

The message about connecting when the signal improves is not an error, but symptom of a problemHere are the main reasons why it occurs:

One of the most common scenarios is conflict between the 2.4 GHz and 5 GHz bandsMany modern routers combine them into one network (function Smart Connect or Band Steering), but not all devices handle this switching correctly. For example, old printers or smart light bulbs can only work on 2.4 GHz, and the smartphone tries to “improve” the connection by switching them to 5 GHz, where they are not supported.

⚠️ Attention: If you use mesh system (For example, Google Nest Wi-Fi or TP-Link Deco), the notification may appear when roaming between nodesIn this case, check the settings. Fast Roaming (802.11r) in the admin panel.

How to Diagnose the Problem: Step-by-Step Guide

Before making any changes to your router settings, please follow these steps: basic diagnosticsto understand the source of the problem:

Check the Wi-Fi signal strength on your device (in settings or through an app like Wi-Fi Analyzer)|

Reboot your router (unplug the power for 30 seconds)|

Try connecting to the network from another device|

Disable Band Steering in your router settings|

Check if your antivirus or VPN is blocking your Wi-Fi connection-->

If the problem occurs on specific device (for example, only on Samsung Galaxy or LG TV), try the following steps:

1. Forget the network and reconnect:

   On Android: Settings → Wi-Fi → [Your network] → Forget
   On iOS: Settings → Wi-Fi → ⓘ → Forget This Network

2. Disable automatic connection (on iPhone: Settings → Wi-Fi → Auto-Join).
3. Check your IP settings: If the device does not obtain an address automatically, assign a static IP manually.

For Smart TV (For example, Samsung QLED or Sony Bravia) additionally:

• 🔌 Switch from DHCP to a static IP in the network settings.
• 📺 Turn off the feature Wi-Fi Direct (may conflict with the main network).
• 🔄 Update your TV firmware via Settings → Support → Software Update.

Configuring your router to fix the problem

If diagnostics show that the problem lies with the router, make the following changes to its settings. Log in to the admin panel (usually at the address 192.168.1.1 or 192.168.0.1, login/password - on the device sticker).

1. Separation of 2.4 GHz and 5 GHz bands

If your router combines networks into one name (SSID), separate them:

• 📡 Go to Wi-Fi Settings → Basic Settings.
• 🔄 Turn it off Smart Connect or Band Steering.
• 📛 Assign different names to networks (eg. MyWiFi_2G And MyWiFi_5G).

2. Selecting the optimal channel

In the range 2.4 GHz Channels are often overloaded. Use the app. Wi-Fi Analyzer (Android) or NetSpot (macOS/Windows) to find the least crowded channel and set it manually:

Wi-Fi Settings → Channel → Select channel 1, 6, or 11 (for 2.4 GHz)
For 5 GHz: Select channels 36-48 or 149-165 (if DFS is supported)

3. Setting the transmission power

On some routers (for example, ASUS RT-AX88U or Keenetic Ultra) you can adjust the signal strength. If the devices are close to the router, reduce power up to 50–70% to reduce interference:

Settings → Wireless → Transmit Power (Tx Power)

⚠️ Attention: On routers with firmware DD-WRT or OpenWRT Incorrect power setting may result in overheating devices. Do not exceed the value 20 dBm for 5 GHz.

4. Firmware update

Outdated router firmware can cause conflicts with modern devices. Check your firmware is up-to-date:

• 🔄 Go to Administration → Firmware Update.
• 📥 Download the latest version from the manufacturer's official website (for example, TP-Link or ASUS).
• ⚠️ Do not update firmware over the air (via Wi-Fi) - use an Ethernet cable.

Features for different devices

Signal enhancement algorithms vary depending on the platform. Let's look at the nuances for popular devices.

📱 Android (Samsung, Xiaomi, Google Pixel)

On Android The service is responsible for optimizing Wi-Fi Wi-Fi Assistant (Part Google Play Services). To disable it:

1. Open Settings → Google → Google services → Wi-Fi optimization.
2. Disable the option Automatic connection to open networks.
3. IN Settings → Network & Internet → Wi-Fi → Advanced turn it off Switching to a mobile network.

🍎 iPhone and iPad

On iOS the problem is often related to the function Auto-Join And Private Wi-Fi Address (random MAC address). To fix:

Settings → Wi-Fi → [Your network] → ⓘ → Disable:
- Auto-connection
- Private Wi-Fi address

📺 Smart TV (Samsung, LG, Sony)

TVs are especially sensitive to signal quality due to video streaming. For Samsung QLED:

• 🔧 Go to Settings → General → Network → Open network settings.
• 📡 Choose Wireless connection and specify it manually DNS (For example, 8.8.8.8 or 1.1.1.1).
• 🔄 Turn it off Wi-Fi Direct on the menu Network → Advanced Settings.

Why does Smart TV take longer to connect to Wi-Fi?

TVs check not only the signal strength, but also connection speed (4K video streaming requires ≥25 Mbps). If your router is delivering low speeds, your TV may get stuck during the optimization phase, trying to find a more stable channel. Solution: manually lock your TV to the 5 GHz band or use an Ethernet cable.

Additional ways to improve your Wi-Fi signal

If setting up your router doesn't help, consider hardware and software solutions to enhance the signal:

1. Repeaters and Mesh systems

If the problem is coverage area, use:

• 📶 Repeater: suitable for small houses (eg. TP-Link RE605X for Wi-Fi 6).
• 🕸️ Mesh system: ideal for multi-room apartments (Google Nest Wi-Fi, ASUS ZenWiFi).

2. External antennas and amplifiers

For routers with removable antennas (for example, ASUS RT-AX86U) can be installed antennas with a gain of 9 dBi. Alternative - Wi-Fi amplifier chip-based Qualcomm IPQ4019 (For example, Keenetic Plus).

3. Software tools

For diagnostics and optimization:

• 📊 NetSpot (coverage analysis).
• 🛠️ Wi-Fi SweetSpots (router location optimization).
• 🔍 Fing (search for interference from neighboring networks).

⚠️ Attention: When using repeaters Connection speed may drop by 30–50% due to double signal retransmission. For stable 4K streaming, it's better to use Mesh system or an Ethernet cable.

Common mistakes and how to avoid them

Many users make the problem worse by taking incorrect actions. Here typical mistakes and their solutions:

Critical error: ignoring router firmware updates. Manufacturers regularly release patches to address vulnerabilities in Wi-Fi protocols (e.g., KRACK or FragAttacks), which may cause connection problems.

FAQ: Answers to Frequently Asked Questions

Why does the notification only appear on some devices?

This is related to different connection algorithms. For example, iPhone uses aggressively 802.11r (Fast Roaming), which may conflict with the router settings. Android the problem often lies in the service Wi-Fi Assistant, which tries to connect to the "best" network, even if the current one is stable. Solution: Disable automatic connection in your device settings.
