cristi101, thank you for your patience.
I have some information that I would like to share with you.
Creating an Ad-Hoc network in 5 GHz is not possible due to regulatory requirements, an ad-hoc network is not supported in 5 GHz using Intel® Wireless Adapters. Our drivers support a hotspot configuration, but in order to make work you need a third party software. If you are using Windows® 10, it has its own way to do it and we recommend to follow this; https://support.microsoft.com/en-us/instantanswers/c60dcfa3-c596-41d4-8c1a-b0d738e1d9fd/use-your-pc-as-a-mobile-hotspot. If you are using Windows 8 or 7 use these steps; http://www.intel.com/content/www/us/en/support/network-and-i-o/wireless-networking/000005772.html
I would also like to let you know that hosted networks are no longer supported after driver version 18.20; the option to create hosted networks was removed from Intel drivers. And, the reason why this option was removed is because Windows® 10 (Anniversary update) comes with a driver called WDI that has a similar option called mobile hotspot.
For information can be found here; http://www.intel.com/content/www/us/en/support/network-and-i-o/wireless-networking/000006057.html
Hope this helps.
I have Windows 10 Creators Update.
I don't know what limitations Intel Wi-Fi adapters have. I've tried from the begining exactly what your Microsoft link is saying to enable a hotspot in 5 GHz but without succes.
I don't know about any regulations. It is just a function of the operating system and I think it should work.
The 2.4 GHz hotspot is working.
The 5 GHz connection to the router is working.
But when I try to share the wired ethernet connection by starting a 5 GHz hotspot, I get an error that the band is not available.
Obviously cannot be any regulation involved because 5 GHz routers exist.
cristi101, thank you for your patience.
The regulation is just for hot spots, not routers. I just wanted to let you know that the information we have from Intel is located here: Frequently Asked Questions about Intel® Wireless Adapters.
For more information about regulations, I would highly recommend visiting: Wi-Fi Alliance.
Then why is there an option for 5 GHz hotspots in Windows 10 ?
The option should work for those Wireless Adapters that support the Ad-Hoc network in 5 GHz. Unfortunately, Intel® Wireless Adapters do not support this as mentioned before.
You said Intel adapters don't support 5 GHz ad hoc due to regulation but you admit there are Wi-Fi adapters that support 5 GHz.
Those regulations are especially made only for Intel ?
I think this is just an excuse for Intel to sell half arsed products.
I did not expect to buy a modern computer from a supposedly reputable manufacturer and have this problem.
I don't know much about how these wireless adapters work, but to me a hot spot with wired ethernet Internet connection sharing is very similar to a router (it routes packets so it must be a router).
Why the adapters would use ad hoc connections in such a case is beyond me.
I see no reason why Intel would not fully support 5 GHz Wi-Fi when others did. Especially when the Wi-Fi adapter is soldered and cannot be replaced and the Wi-Fi adapter is in a Intel designed device, not sold to third parties.
The only regulation I was able to find regarding 5 GHz band was about radar detection.
I use the computer inside and around here the walls are not made from wood.
I think there is no way it could interfere with any radar that may be nearby.
Another product that lie by claiming it implements the standards is Windows 10 bluetooth implementation.
I was previously able to make and take phone calls from a computer by cell phone via bluetooth but the Windows 10 free upgrade declared the bluetooth software is incompatible with it. Microsoft claim Windows 10 implements most bluetooth profiles, but this is obviously a lie. It implements half of each profile.
Screwing up customers is becoming a sport these days.
