Iphone 15 pro lost 6ghz connection after one day
I installed a TP Link Wifi 7 router (Aginet) from Singtel on 10gb broadband a few days ago. Setting to MLO, I was able to secure the wifi speed of about 1450 mbps on my Iphone 15 pro. I believed I had successfully logged on to the 6ghz band in the MLO. Although the speed on VPN dropped to about 300 mbps.
Strangely, one day after the installation, the wifi speed on my Iphone 15 pro dropped to about 700mbps. I suspect the 6ghz connection was lost, but the speed on VPN improved to about 500mbps. I searched around for answers on the internet and learned a few things here and there but did not find anyone sharing the same problem as me. I tried changing the wifi settings from the advice I gathered but to no avail so far. Everything looks perfect on the Router connectivity and Internet download speed. Therefore, I believed the problem lies with the system in the Iphone 15 pro. But in any case, I would be grateful for any help and advice here to resolve my problem. Thanks!
@David-TP Yes, it is a HB810. Anyway, contacted Singtel and was informed there was a fibre optical issue in my home connection. They are sending technician down to check - hope the issue would be resolve in due course. Thanks for the advice anyway 
@nico887 - Hi Nico, my problem remains unresolved to-date. My ISP (SINGTEL in Singapore) has arranged for a site visit with an Engineer from TP-Link this coming Sat. I am not hopeful that they would be able to resolve the problem as I firmly believe it has nothing to do with the wifi settings anymore (tried every combo there is). But it would be good that the Engineer could see the problem himself and take it back to TP-Link lab to study. A firmware update is likely to be needed here.
Your situation is slightly better than mine - at least you could see the 6 ghz broadcast. I have to put up with an illusive 6 ghz broadcast that only visits once a while for a very short period each time! 
I will get back to you after this Sat.
