Limited Compatabilitiy on wifi 6E

It has nothing to do with the SSID. How old is the router? If it wasn’t purchased new in the last year it can’t support the full bandwidth of Wi-Fi 7; the Wi-Fi 7 and 6 GHz standards are relatively new and has been in flux until recently. The final specification has not been ratified, and isn’t expected until the end of this year (in theory, about now). Is the message coming from your iPhone or from the router? Have you updated the firmware in the router?

The important question is what throughput do you get when measured within 3 meters of the router on 6 GHz? If you get close to the maximum for your internet connection then it doesn’t matter what “Limited Compatibility” actually means. And keep in mind that 6GHz has a much shorter range than 5Ghz, which is also shorter than 2.4 GHz.

The draft standard is up to 23 Gbps, but unless your internet connection is the same or higher than 58 Gbps you won’t see that. About the highest available for the home market is Verizon’s 2 Gbps FiOS service, and the the highest of any other vendor is 1 Gbps, with many much lower.

The other possibility is the iPhone currently only supports 160 MHz bandwidth, but the standard also supports 320MHz, which is required to meet the 23 Gbps. If the message is coming from your router, and not the iPhone, that may be the cause.

Sorry, Reply is bellow: Looking on the web a lot of people are having this issue on diffrent routers with the Iphone 15/16.

Again, thanks for the reply, It may be the 160MHZ limit on the Iphone, or the router but I know others who have this router and have great fast 6G speeds when near it of course.

What are “great speeds”? Even 5GHz connection speeds are limited by the bandwidth of the internet connection (which is rarely above 1 Gbps, and usually less) and the bandwidth capabilities of the connected devices. I find it unlikely that any home network configuration is capable of taking advantage of the throughput of even 5 GHz, let alone 6 GHz.

6G and 7G are here, as 5G came out back in 2013 they will make it less crowded on the 5G channel as everyone has LOT devices and Wi-Fi nowadays. Anyways, I was hoping you or someone had a solution. My Home network gets 800 upload speeds on my 5G and only 180 uploads speeds on 2.4 so I guess I am already taking advatage of faster speeds. It's just progress and it should just work as 6G was tested and used 4 years ago and now is out for close range wifi use along with 7G.

What is your internet connection speed; the bandwidth you pay your ISP for?

Wi-Fi 6 is NOT the same as the 6 Ghz frequency band. Wi-Fi 6 can actually use the 5 GHz band quite happily; it is a different coding standard, not a frequency band. And there are no 7 GHz Wi-Fi bands; that’s reserved for radar. Wi-Fi 7 is again a different coding standard.

2.4 GHz frequency band speeds are much slower than 5 Ghz or 6 GHz bands, but not because of the frequency band; it’s because the coding used at 2.4 GHz is different and was never upgraded, because most IoT devices do not support the coding for the higher bands.
