A simple setup can dramatically accelerate the hotspot on your Android phone

By changing a simple setting, you can share your phone's 4G or 5G connection better.

If you use your phone as a hotspot, you have an Internet connection everywhere that is far more secure than using free public Wi-Fi. However, if you have an Android phone, you may not get the fastest possible speed. This means that websites on your laptop or tablet, for example, load much slower than they could.

Testing the 5G networks of Sprint and Verizon in Chicago, I wondered what would happen if shared the fast connections with an iPhone with 4G-Limit ($ 1,000 at Best Buy) over Wi-Fi. While the S10 5G on Sprint reached fairly constant speeds between 100 and 200 Mbps during the day (and a S10 5G on Verizon between 400 Mbps and 800 Mbps), the iPhone had difficulties over 30 Mbps get out. A similar problem occurred when T-Mobile's 5G network was tested in New York last month .

So what is there? After confirming with Samsung and the network operators that no one has reached the top speed, and checking out other devices, including OnePlus 7 Pro and LG V50 ThinQ ($ 1,222 at Best Buy) 5G, the problem seems to be In an Android setting, Wi-Fi hotspots transmit Wi-Fi over a slower 2.4GHz frequency rather than over the much faster 5GHz frequencies.

When I switched to 5 GHz at the mobile hotspot, I saw a speed jump. After the iPhone XS Max ($ 1,100 at Best Buy) had trouble crossing the 30-Mbps limit over Wi-Fi, it was able to switch the hotspot settings of Sprint and Verizon in each 5G network of the respective network operator reach speeds of over 300 Mbit / s.

In a similar test with the OnePlus 7 Pro connected to Verizon's 4G LTE network in New York City, the download speed improved from 33.1 Mbps to 2.4 GHz to 86 , 1 Mbit / s over 5 GHz. Interestingly, the upload speeds seemed to be okay with both bands.

Why is there a difference?

As with 5G mobile phones, there are many different types of Wi-Fi and a few frequencies that can be used. The 2.4 GHz band is great for directing the Wi-Fi signal to greater distances from the router. However, this is slower and more prone to interference from other devices such as cordless phones, baby monitors and even microwaves.

The 5 GHz band (also known as the 5G) is much faster and works with less interference, although its range is much shorter.

Since nothing is so easy, your home router may display 2G and 5G versions of your network, although these Wi-Fi networks are different from those provided by mobile operators. In short, use your router's 5 GHz connection at home when it's available for the fastest speeds, especially on devices such as 4K TVs or game consoles.

When streaming to a 4K TV, use 5 GHz WiFi if available.

Since your phone is often near the device you're connecting to, the 5 GHz range limits should not be a major issue.

Most modern devices can connect to Wi-Fi on both bands. However, some older devices only detect 2.4GHz. For this reason, it makes sense if this is the default option.

How to make sure your phone's hotspot is transmitting at 5 GHz. We give examples of three different manufacturers, but if you have another Android phone that supports 5 GHz, the steps should be quite similar.

Samsung Phones

Step 1. Go to Settings [194559006] Step 2. Tap on "Connections" and then on "Mobile Hotspot and Tethering"

Step 3. Click "Mobile Hotspot" and then tap the three dots in the upper right corner.

Step 4. Tap Configure Mobile Hotspot. This will allow you to change the network name and Wi-Fi password for your hotspot, but scroll down and select "Show advanced options."

Step 5. Select "Use 5 GHz Band if Available".

Selecting the 5GHz band allows much faster sharing of hotspots.

LG Phones

Step 1. Go to Settings [194559006] Step 2. Select "Tethering"

Step 3. Tap "Wi-Fi hotspot" and click "Set Wi-Fi hotspot"

Step 4. Scroll down the pop-up window and click "Show advanced options."

Step 5. Switch from Preselected "2.4GHz Band" to "5GHz Band"

Step 1. Go to Settings [19659006] Step 2. Select "Wi-Fi & Internet"

Step 3. Select "Hotspot & Tethering" followed by "Wi-Fi Hotspot".

Step 4. Change the "2.4GHz band" AP band to "5GHz band".

What about iOS? Apple does not allow iPhone users to change the band on which Wi-Fi is broadcast via the Personal Hotspot iOS feature. For optimal speed, it is recommended to connect the phone directly to a laptop. Regardless of Android or iPhone, no settings need to be changed to complete the full high-speed connection.
