The 2.4GHz band is great for pushing the Wi-Fi signal to distances far from the router, though it does so at slower speeds and is more susceptible to interference from other devices like cordless phones, baby monitors and even microwaves. Why is there a difference?Īs with cellular 5G, there are many different flavors of Wi-Fi and a few frequencies that can be used.
Here's how to make the change on your devices. A quick switch to 5GHz nearly tripled the throughput, boosting the connection to 116Mbps in the same location. While this was in 2019, you could still be encountering the same issue in 2021 with 2.4GHz as the default hotspot setting.Ĭonnecting an iPhone 12 Pro Max to a Galaxy S21 Ultra 5G on T-Mobile's 5G network in New York earlier this year saw download speeds of 33.6Mbps over 2.4GHz. After struggling earlier to break the 30Mbps barrier over Wi-Fi, switching both Sprint and Verizon's S10 5G hotspot settings allowed the iPhone XS Max ( $425 at Amazon) I was using to get speeds above 300Mbps on each carrier's respective 5G network. Switching to 5GHz on the mobile hotspot, I saw download speeds jump. So what gives? After confirming with Samsung and the carriers that nobody was capping speeds, and checking out other devices including the OnePlus 7 Pro ( $349 at Amazon) and LG V50 ThinQ 5G, it appeared that the issue lies in an Android setting that has Wi-Fi hotspots broadcast Wi-Fi over a slower 2.4GHz frequency, instead of the much faster 5GHz. While the Samsung Galaxy S10 5G on Sprint pulled in fairly consistent download speeds between 100 and 200Mbps throughout the day (and an S10 5G on Verizon getting between 400Mbps and 800Mbps) the iPhone was having a hard time getting past 30Mbps. Testing out Sprint and Verizon's 5G networks in Chicago in 2019, I was curious to see what would happen when sharing the speedy connections with a 4G-limited iPhone over Wi-Fi. But if you have an Android phone, you might not be getting the fastest speeds you can, which means that websites on your laptop or tablet, for example, load much slower than they could. Using your phone as a hotspot gives you an internet connection anywhere, and one that's far more secure than using free public Wi-Fi. Changing a simple setting could let you better share your phone's 4G or 5G connection with others.
