How to Increase Internet Speed ​​on Your Phone When Sharing Wi-Fi: A Complete Guide

Sharing internet from your phone is a convenient way to connect a laptop, tablet, or other gadget to the network when there's no router at hand. However, users often encounter the following problem: low speed, connection breaks or high ping, especially if multiple devices are connected to the hotspot. The problem isn't always your mobile carrier's plan: even with stable 4G/5G, the speed on connected devices can drop by 2-3 times.

In this article we will analyze technical and software optimization methods that will help Increase your phone's Wi-Fi speed by 30–70% without purchasing additional equipment. The emphasis is on customization. Android And iOS, choosing the right frequencies (2.4 GHz vs 5 GHz), as well as little-known tricks that carriers and smartphone manufacturers don't advertise. All recommendations were tested on devices manufactured between 2020 and 2026.

If you are distributing the Internet with iPhone 12 or Samsung Galaxy S23, but the speed on your laptop doesn't exceed 10 Mbps—this guide is for you. We'll start with simple settings and move on to advanced methods, including changing parameters. MTU and work with DNS.

1. Check your actual mobile internet speed

Before optimizing your data distribution, make sure the issue isn't with your carrier's network connection itself. Speeds on your phone and connected devices can differ by 2-5 times due to network restrictions. access points (hotspot).

How to check:

• 📱 Turn off Wi-Fi sharing on your phone.
• 📊 Run a speed test on your phone itself via Speedtest or nPerf (applications are available for Android And iOS).
• 🔄 Repeat the test 2-3 times in different places (for example, near a window and in the back of the room).
• 📶 Compare the results with the stated speed of your plan (check in your operator account).

If the speed on your phone is lower 50% of the tariff, the problem lies with your carrier's coverage or network settings. If the speed is normal but drops when tethering, read on.

⚠️ Attention: Operators may artificially limit the speed when distributing the Internet (the so-called throttling). For example, Megaphone And Beeline Some plans reduce hotspot speed to 10 Mbps, even if your phone has 100+ Mbps. Check your contract for details.

2. Select the optimal Wi-Fi frequency: 2.4 GHz or 5 GHz

Modern smartphones support Wi-Fi distribution on two frequencies: 2.4 GHz And 5 GHzEach has its pros and cons:

How to choose:

• 🏠 If you are distributing the Internet in large apartment or on the street - use 2.4 GHz (better coverage).
• ⚡ If needed maximum speed at short distances (up to 10 m) - switch to 5 GHz.
• 📱 On iPhone the frequency is selected automatically, but on Android can be set manually (see next section).

⚠️ Attention: On Android 12+ And iOS 15+ Some manufacturers hide the frequency selection in the settings. In this case, use apps like WiFi Analyzer (Android) or Network Analyzer (iOS) to force switching.

Make sure the connected device supports 5GHz|

3. Configure hotspot settings on Android

On smartphones running Android (including Samsung, Xiaomi, Google Pixel) There are hidden settings that affect download speed. Let's look at the key parameters:

Step 1: Change the Wi-Fi mode (802.11n/ac/ax)

• 🔧 Go to Settings → Connections → Mobile hotspot & tethering.
• 🔍 Find the item Wi-Fi mode or Wi-Fi standard (on Xiaomi can be called AP Band).
• 📶 Select 802.11ac (For 5 GHz) or 802.11n (For 2.4 GHz). If there is 802.11ax (Wi-Fi 6) - turn it on.

Step 2: Set up a static channel

By default, the phone selects a channel automatically, but this isn't always optimal. To set it manually:

1. Download WiFi Analyzer from Google Play.
2. Run a scan and find the least loaded channel (for example, Channel 6 For 2.4 GHz or Channel 149 For 5 GHz).
3. In the access point settings, find Wi-Fi channel and install the selected one.

Step 3: Disable Energy Saver

On Samsung And OnePlus the option is enabled by default Saving battery when using a hotspot, which limits speed. Disable it:

Settings → Device Maintenance → Battery → Power Saving Mode → Disable for "Mobile Hotspot"

4. Optimizing Wi-Fi Sharing on iPhone (iOS)

On iPhone (including models iPhone 13/14/15) the possibilities for fine-tuning are limited, but there are several working methods:

Method 1: Enable Maximum Compatibility Mode

• 🔧 Go to Settings → Tethering.
• 🔄 Turn on the option Maximum compatibility (if any). This disables Wi-Fi 6, but stabilizes the connection with older devices.

Method 2: Reset network settings

If your speed drops after updating iOS, reset your network settings:

Settings → General → Transfer or reset iPhone → Reset → Reset Network Settings

After the reset you will have to re-enter your Wi-Fi passwords, but this often solves problems with delays (ping).

Method 3: Disable Low Data Mode

Traffic saving mode (Low Data Mode) may limit the distribution speed:

Settings → Cellular → Data Options → Low Data Mode → Off

⚠️ Attention: On iOS 17+ Apple has added a limit on the number of devices that can be connected to a hotspot (maximum 5 simultaneously). Connecting more devices will reduce speed by 2-3 times.

5. Advanced settings: MTU, DNS, and IP addresses

If the basic methods don't help, try changing network parameters, which affect data transmission:

Setup 1. Change MTU value

MTU (Maximum Transmission Unit) — the maximum data packet size. Optimal value for mobile internet: 1472 or 1480How to change:

• 📱 On Android with root rights use the command:

  adb shell ifconfig wlan0 mtu 1472

• 🍎 On iOS change without jailbreak MTU it is forbidden.

Setup 2: Use Alternative DNS

Your operator's DNS servers may be slowing down your connection. Try this. Cloudflare or Google DNS:

• 🌍 1.1.1.1 (Cloudflare) - minimal delays.
• 🔍 8.8.8.8 (Google) - stable work.

On Android change DNS in the access point settings (Settings → Connections → Mobile Hotspot → Configure → DNS). On iOS This cannot be done - DNS changes only for connected devices.

Setup 3. Set a static IP address

Dynamic IP allocation (DHCP) may cause delays. Set the static range:

Access point settings → Configure → IP range: 192.168.43.2–192.168.43.100

What is MTU and why is it important?

The MTU (Maximum Transmission Unit) determines the maximum size of a single data packet transmitted over the network without fragmentation. If the MTU is too large, packets will be fragmented, increasing the load on the phone's processor and latency. For mobile internet, the optimal value is 1472–1480, as operators often use PPPoE with an 8-byte overhead.

6. Hardware methods: cooling and external antennas

If the phone overheats while distributing Wi-Fi, the speed will automatically decrease due to throttling (overheating protection). How to avoid this:

• ❄️ Remove the cover while distributing - it impairs heat dissipation.
• 🔋 Do not use your phone for games or videos during the distribution.
• 🌡️ If the temperature exceeds 45°C (check in AIDA64), take a break for 10-15 minutes.

To improve the signal:

• 📡 Use Wi-Fi repeater (repeater), if you distribute over a long distance.
• 🔌 Connect your phone to a charger - when the battery level is low (<30%), the speed may drop.
• 📶 For Android-phones with support OTG can be connected external antenna (For example, Alfa AWUS036ACH).

⚠️ Note: External antennas only work on phones with a jack USB-C and support USB OTGOn . iPhone This method is not applicable without a special adapter (and even with it the efficiency is minimal).

7. Alternative methods of distributing the Internet

If Wi-Fi is slow despite all the settings, try other connection methods:

• 🔌 USB cable: Connect your phone to your laptop via USB-C or LightningThe speed will be higher than Wi-Fi, and your phone's battery won't drain. Windows You may need to install a driver RNDIS.
• 📶 BluetoothSlower than USB, but more battery-efficient. Suitable for text or email transfers.
• 🔄 Bridge mode (Wi-Fi Repeater): Some phones (eg. Samsung Galaxy S22+) can rebroadcast the router's signal instead of mobile internet. This is useful if you have weak Wi-Fi but a good router.

8. Resolving problems with the operator and tariff

Sometimes low upload speeds aren't related to your phone, but to carrier limitations. What to check:

• 📄 Tariff terms: Some operators (eg. Tele2) Traffic for distribution is charged separately. Check your personal account.
• 📡 Network type: If the phone is connected to 3G instead of 4G/5G, the speed will be slow. Manually select the network in Settings → Cellular → Network Type.
• 🔄 APN settings: Incorrect parameters APN may be limiting your speed. Reset them to factory defaults or request the latest ones from your operator.

If the operator artificially limits the distribution speed, consider:

• 🔄 Changing the tariff to an unlimited one with distribution (for example, Unlimited from MTS).
• 📶 Connecting external 4G/5G modem (For example, Huawei E5577).

⚠️ Please note: Operators often impose data transfer limits on "unlimited internet" plans (e.g., 10 GB per month at full speed, then 64 kbps). Check your contract for details.

FAQ: Frequently asked questions about sharing Wi-Fi from your phone

Why is the speed on my laptop slower than on my phone?

This is normal: when distributing data, it passes through the phone's processor, which limits bandwidth. A 30-50% drop is typical. Other factors that can affect this include:

• Laptop connection type (Wi-Fi 4 vs Wi-Fi 6).
• Channel load (check in WiFi Analyzer).
• Operator restrictions (throttling for hotspot).

Is it possible to share internet from a phone to a Smart TV?

Yes, but there are some nuances:

• Samsung And LG TVs support connection to a phone as a router.
• On Android TV (For example, Xiaomi Mi Box) manual IP entry may be required.
• For 4K streaming Mobile internet speed is usually not enough (25+ Mbps is needed).

How to share internet from your phone without speed limits?

It is impossible to completely remove restrictions, but they can be minimized:

1. Use USB cable instead of Wi-Fi.
2. Connect external 4G modem with support Wi-Fi 6.
3. Select a tariff without distribution restrictions (for example, Beeline's Unlimited Device Plan).

On Android With root access, you can disable throttling by editing a file /system/build.prop (line net.tethering.noprovisioning=true), but it's risky.

Why does Wi-Fi hotspot turn off on its own?

Reasons and solutions:

• Battery saving: Disable power saving mode for the access point.
• Overheat: Let the phone cool down or remove the case.
• Operator limitation: Some tariffs turn off distribution after 30–60 minutes.
• Firmware bug: Update Android/iOS to the latest version.

How to share internet from an iPhone to a Windows PC without iTunes?

On iPhone USB sharing requires a driver Apple Mobile Device USB Driver, which is installed together with iTunes. Alternatives:

• Use Wi-Fi or Bluetooth.
• Install iTunes for driver only, then uninstall the program via Control Panel → Programs (the driver will remain).
• For Windows 11 The driver can be downloaded separately from the Apple website.
