Bad Realtek wifi hardware/card on Win 10 HP, full rebuild necessary?

To clarify, when I tried the external antenna, I disabled the ethernet and disabled the native wifi adapter. Haven't I isolated booth the antenna and the card this way?

I did learn here I should boot from USB and try the external antenna.

What troubleshooting steps were performed with HP support?
Any hardware testing?

Also, another point, if you send it back to HP, they are going to replace the existing WiFi card with the exact same model that is in there now. The next troubleshooting step, in my opinion, is to boot from Linux on a USB flash drive.

Should I use this?
Create a bootable USB stick on Windows | Ubuntu

thank you

I have gone through a variety of troubleshooting steps, tests, diagnostics, etc both myself from tutorials and twice with HP techs on chat with remote access. Hours. Way more than I can list.

Thanks

That sounds similar to the 25Mbps Wireless DSL I use, a dish aimed at an antenna on a hill.

hrmmmm Are we neighbors? is it on a church on a hill?

See post #4 for testing options.

There are also tons of settings from the device manager properties for the WiFi adapter that can be changed:

Attachment 311337

I have to say that despite hours of tweaking and testing. I do not recall adjusting a single setting on that advanced properties tab.

Yes definitely done that repeatedly , thanks. Also dumped winstack/IP. Updated, rolled back, and reinstalled drivers. Update bios. Reset networks. Forget wifi routers. Updated router firmware. Windows updates. Virus scan. Tweaked some device setting about power management and IP6. Even did a power drain.

NavyLCDR call my attention to a relevant point. Other nearby routers can be using same frequency / channel.
Nowadays there are so many routers on the area that an interference can occur.
Download, extract and run WifiInfoView.
WifiInfoView scans the wireless networks in your area and displays extensive information about them.
