I think this might be the reason. 5ghz wifi band has considerably less range then 2.4ghz band. You can google it up. So if you test your speed at the same place then 2.4 ghz will obviously have better speed and coverage than 5ghz band.
You're Using the Wrong WiFi Channel
Each WiFi frequency band is broken up into several “channels,” which are used to send and receive wireless data. The 2.4 GHz band has three non-overlapping channels to choose from, while the 5 GHz band has up to 24 non-overlapping channels.
The 2.4 GHz Wi-Fi frequency band uses lower frequencies than the 5 GHz Wi-Fi frequency band—that's why 2.4 GHz Wi-Fi is better at penetrating solid objects and why it gives you more Wi-Fi range than the 5 GHz frequency band.
For help with slow speeds when not on the 5G network, please head here. There are a few factors that can impact your data speed, which includes: Your phone - Is your phone 5G compatible? Too many data sessions - Do you have any too many apps open?
1. Check for any software updates and install them if available – this will ensure that you are using the most up-to-date version of iOS which could help with performance issues. 2. Restart your device – this can often help resolve simple technical issues.
Ideally, you should use the 2.4GHz band to connect devices for low bandwidth activities like browsing the Internet. On the other hand, 5GHz is the best suited for high-bandwidth devices or activities like gaming and streaming HDTV.
In some cases, turning off 5GHz may improve WiFi because it can reduce interference and improve the stability of the connection. However, in other cases, turning off 5GHz may actually worsen WiFi because it can limit the available bandwidth and reduce the overall performance of the connection.
On the 5 GHz band, set the channel width to 40 MHz and see if that improves reliability. Keep in mind that 80 MHz and 160 MHz channel widths may carry the promise of extra speed, but will also interfere with, and receive interference from, many more sources than 40 MHz.
Auto or all channel widths for 5GHz and 6GHz bands ensures the best performance and compatibility with all devices. Wireless interference is less of a concern in these bands.
A 2.4 GHz connection travels farther at lower speeds, while 5 GHz frequencies provide faster speeds at shorter range. Your choice of 2.4 GHz or 5 GHz will depend on where and how you use your WiFi connection most.
The 5 GHz band has a lower range because higher frequencies can't penetrate solid objects such as brick walls. It is however faster. In addition, your connection can be slower in either band due to interference from other WiFi enabled devices and things like microwave ovens.
Simultaneous dual-band routers are capable of receiving and transmitting on both 2.4 GHz and 5 GHz frequencies at the same time. This provides two independent and dedicated networks which allows more flexibility and bandwidth.
Theoretically, multiple devices connected to Wi-Fi doesn't slow down the internet speed. But in practice, more the number of devices are connected to the internet, the bandwidth is being shared thus affecting the speed.
5 GHz networks do not penetrate solid objects such as walls nearly as well as do 2.4 GHz signals. This can limit an access points reach inside buildings like homes and offices where many walls may come between a wireless antenna and the user.
Using a 5Ghz frequency, you will get about 50 feet or about 15 meters of reach. The reach of your signal will be impacted by the manufacturer of the equipment that you are using, the location your router is installed, and the obstructions that might block the signal in your home or business.
If you're able to use most of your devices near your router, 5 GHz is your best choice to take advantage of higher speeds. Similarly, if you're doing a lot of high-bandwidth activities online, such as gaming or videoconferencing, it's best to use this frequency and move as close as possible to the router.
Ethernet is faster than WiFi because it connects through a physical cable rather than a signal – and a wired connection is always faster and more reliable than any wireless, whether WiFi 6 or 5G. The fastest average speed of Ethernet is around 10 Gbps, making it the fastest Internet option.
The most known standard that it (5 GHz) is supported is on and the 802.11ac. Therefore the standard is dependent on the speed a connection encompasses and they bring the difference in both differences in speed of the WiFi and Ethernet.
In the battle of Ethernet vs. WiFi, an Ethernet connection is the best choice for incredible download speeds. Most modern gaming devices take advantage of a 5GHz wireless connection. Still, you will experience a slower speed than Ethernet, even if it's just a few Mb/s.
5G up to 100 times faster than 4G
In the right conditions 5G download speeds can reach 10 gigabits per second. That's up to 100 times faster than 4G – and certainly the level of performance needed for an increasingly connected society.
The iPhone 11 is using different cellular bands than the iPhone 13 can. Since fewer phones can use the bands the iPhone 13 can, they will always appear to be less congested. Unfortunately, the cell towers are not always properly optimized for the new frequency bands. Further, 5G itself is slower than LTE in many areas.
