Weak Wifi Signal on Any Network, other Laptops in House not Having this Issue

[Olimig123]

My laptop has only 2 Signal Bars even when I'm within 6 feet of my router. I've tested this with other networks and the issue persists. My partner has the same exact laptop and has no issues with connectivity.

I've tried forgetting the Wifi, restarting, and remembering it. Tried uninstalling the Network Adapter (Realtek RTL8723DE) and restarting to have it auto reinstall. I've tried going through the HP Virtual Desk. Tried calling Verizon to fix any issues with our internet/router. I've taken it to Best Buy and they told me to contact the manufacturer for updated drivers, but from my searches, I already have the most up to date drivers (think the most recent came out in May of 2021). I've tried messing with DNS Settings a bit as well and nothing has worked.

Wondering if there's something physically wrong with the Network Adapter. If anyone has this issue or any other ideas for a solution, please let me know!

Hi:

This is the latest driver for the model wifi adapter your PC has:

If that doesn't help any, the Wi-Fi adapter may have a hardware issue of some kind.

If you decide to replace it, you may as well upgrade it to 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.
