TX55E (UN Ver 1.2) Can't connect to 5Ghz wifi
I just bought a PCIE TX55E Adapter, but I found a problem where the 5ghz Wi-Fi won't connect. My main router uses Archer AX73 US Version 2. At the beginning, since it was turned on, it was connected to 5Ghz Wi-Fi Channel 36 Aggregated link speed (Receive/Transmit): 1922/1297 (Mbps) normal at the beginning when I turned on the PC, but after I restarted everything went wrong where the 5ghz Wi-Fi won't connect anymore, it's always rejected and until now I can't connect to 5ghz Wi-Fi from the ax73 router, this is the 2nd unit after I submitted a request for a new item and the new item also has the same problem
PC Specs
Intel Core i5-10400f
MSI B460M Mortar Motherboard No Wi-Fi BIOS Latest Update
POWER SUPPLY FSP PSU HV PRO 550W 80+
Please help me, is this a firmware bug or what, because at the beginning of the installation it was normal but after restarting it couldn't use 5Ghz. For 2.4Ghz it works normally.

ax73 router settings
5GHz 20/40/80 MHz settings
Can connect but the speed drops and this is very disappointing.
Hi, did you purchase Archer TX55E and Archer AX73 both from the local market?
I used to see the local Indonesian WiFi routers prefer using band 4(channel 149-165) over the 5 GHz band.
How about the other 5 GHz devices? Are they able to connect to Archer AX73 when the 5GHz bandwidth is 20/40/80/160 MHz? What is the currently used 5 GHz channel?
When the 5 GHz bandwidth is set to 160 MHz, can you change the channel on the Archer AX73 here to channel 36/48?
Thank you very much.
Wait for your reply.

@David-TP Everything works on my phone, even on the router extender of the other brand, there were no problems. Oh yes, and previously I used Ax12, but I thought because this TX55E needed 160Mhz I upgraded to Ax73, and it turned out to be the same, it couldn't connect to 160Mhz Wi-Fi if it was lowered to 20/40/80 the speed would drop according to my picture, and I have set everything from the router side even from the driver, at the beginning the first time the power was turned on it could connect to 5Ghz Wi-Fi 160Mhz channel 36 full speed, but after I restarted my computer it didn't want to connect to 5Ghz Wi-Fi anymore
