I can create 5GHz Network, But cannot connect to them.

Hello,

I have a "Macbook Pro 2016" and a "Huawei Mate 9" phone.

My Macbook can create 5GHz networks without any issues, and my Mate 9 can connect to them just fine, but not vise versa!

So I cannot connect to Phone-created 5GHz Hotspot with the Macbook.

These are the only 5GHz devices I have, and where I am right now, I don't have any access to the customer support.

Installed "WiFi Explorer" on Macbook and "PingTools Pro" wifi analyzer on the Phone.

WiFi Explorer does not show any 5GHz signal at all.

Is there any way, I can diagnose the issue here?

any help is appreciated.

So to be sure I understand things you can access your MacBook from the Huawei Mate 9 phone via WiFi just not the other way.

With your Mac you created your own peer to peer AP an was able to get the Huawei Mate 9 to connect to your Mac and internet connection it offered.

Within the Huawei Mate 9 you would need to do the same if you wanted to leverage it as a WiFi hotspot. The Mac's P-to-P AP is not needed here only the Huawei Mate 9's P-to- P AP and then you would need to enable the routing function within the phone to use the cellular connection.

Looking at the user manual here: Huawei Mate 9 User Guide jump to the bottom of page 60 it talks about setting up a mobile hotspot. Did you follow the instructions?

Make sure to setup a secured network using WPA2. Alter your phones name and use it with the password you created on the Phone's hotspot settings on your Mac to connect to the phones AP. That should do it.

Thank you for replying,

I created a 5GHz Hotspot on Huawei Mate 9 with the right steps, my Macbook cannot see it or connect to it.

When I choose 2.4 GHz on the Phone it's fine, I can connect to it, the issue is only with 5GHz Hotspot.

I tried 5GHz P-to-P on my Macbook just to check if it works the other way and it did (I can connect to Macbook's 5GHz Network with my Phone).

I tried changing SSID on the phone, restarting Network Settings, restarting both devices, tried using both "WPA2" and "No Password (just to test if I can connect to it)", whitelisted Macbook's Wireless MAC Address, also tried using all 5GHz channels my Macbook supports (36,40,44, etc ...)

but still cannot see or connect to my Phone's 5GHz Hotspot using the Macbook.

TLDR; I'm doing everything correct, tried all settings, but I cannot connect to the 5GHz Hotspot created by my Phone.

I was hoping maybe to get some advanced technical advice here, because if the devices are broken why does it work the other way around?

You do have a very odd problem here! If you can setup a 2.4 GHz connection from the MacBook Pro to the Huawei Mate 9 phone then you've proven you are doing things correctly!

What that tells me is you likely found a bug in the Huawei Mate 9 phone! You'll need to speak directly to Huawei to make sure your phones firmware is up to date. If you can find a friend with the same model you should try to set it up with it. Or, try a second system to connect to your phone.
