Hi, the challenge should be coming from the fact that you had formatted your system so you may need to install the Wireless Driver or update the one that is already existing on your system.

 

Use this link to find compatible wireless drivers for your PC. Scroll down to Driver-Network on the page.

Hi, @15-da0326tu12 

 

It is absolutely impossible that your notebook ever was able to connect to the 5.0 GHz Wi-Fi band.

 

Below is the link to the product specs for your notebook.

 

HP Notebook - 15-da0326tu Product Specifications | HP® Customer Support

 

It comes with a Realtek RTL8723DE Wi-Fi adapter which can only work on the 2.4 GHz Wi-Fi band.

 

Specs on the RTL8723DE Wi-Fi adapter:

 

RTL8723DE - REALTEK

 

If you want to upgrade the internal Wi-Fi card to a dual band model, you can replace the existing Wi-Fi card with this model...

 

Realtek RTL8821CE 802.11 ac 1x1 Wi-Fi + Bluetooth 4.2 Combo Adapter (MU-MIMO supported) HP part # L17365-005.

 

The card has a maximum throughput of 433 MBPS on the 5.0 GHz Wi-Fi band with an AC router and an excellent signal.

 

You can find this model on eBay, or Ali Express. 

 

I see some Intel 3165 cards listed on the eBay listings, so don't buy those.

On the Ali Express listings, make sure the card has the HP Part # of 915620-001.

 

Below is the link to the service manual where you can find the Wi-Fi card removal and replacement procedure...
