Common problems and their solutions

Even with the correct settings iPhone 6s may not connect to Wi-Fi. Let's look at common scenarios and how to troubleshoot them.

Problem Possible cause Solution
The network is not displayed in the list. Hidden SSID or incompatible Wi-Fi standard Enter the network name manually or enable SSID broadcasting on your router.
The connection is interrupted Weak signal or channel congestion Switch the router to a channel 5 GHz (if supported) or change the channel in the settings
Incorrect password (error) Typo or password change on the router Check your keyboard layout and capitalization. If necessary, reset your router password.
Connected, but no internet Problems with DHCP or DNS on the router Reboot your router or manually enter DNS (for example, 8.8.8.8 from Google)

If iPhone 6s connects to the network, but the speed is extremely low (less 1 Mbps), try:

  • 📶 Disable Automatic connection to the network in the Wi-Fi settings (this will prevent switching to weak networks).
  • 🔄 Restart your router and iPhone simultaneously.
  • 🛠️ Enable the mode in the router settings 802.11n/ac (disable obsolete standards b/g).
What to do if iPhone 6s doesn't remember the network?

1. Open Settings → Wi-Fi.

2. Click on the icon ! next to the network name.

3. Select Delete this network.

4. Reconnect by entering the password.

⚠️ Attention: On some router firmware (especially TP-Link And ASUS) MAC address filter is enabled. If iPhone 6s It doesn't connect, check the router settings section Wireless MAC Filter and add the MAC address of your device (you can find it in Settings → General → About → Wi-Fi Address).

Setting up additional Wi-Fi settings

For stable operation Wi-Fi on iPhone 6s Several hidden parameters can be optimized. Let's look at them in detail.

1. Network priority

If there are multiple networks in range (for example, your home network and a neighbor's), your iPhone may connect to the weaker one. To set priority:

  1. Open Settings → Wi-Fi.
  2. Click on the icon ! next to the desired network.
  3. Enable the option Auto-connection and disable it for unnecessary networks.

By default, the iPhone uses the DNS provider. To speed up the internet, you can specify alternative DNS:

  1. In the Wi-Fi settings, tap on ! next to the current network.
  2. Select Configure DNS → Manually.
  3. Add addresses:
    • 8.8.8.8 (Google DNS)
    • 1.1.1.1 (Cloudflare DNS)

3. Low data consumption mode

If you have limited traffic, enable this option:

  1. Go to Settings → Wi-Fi.
  2. Click on ! near the network.
  3. Activate Low data consumption mode.

This mode limits background activity of applications, but may affect real-time updates (for example, in instant messengers).
