Wi-Fi gets no signal even when Pixel 3a or any Wi-Fi for that matter is nches from the Wi-Fi card

[Custom-PC]

I have tried changing system settings, I have tried drivers, I have tried everything I can think of including changing the battery performance to something other than automatic I've tried everything I can think of with the exception of opening it up, and I am afraid to open it up and see if there is a disconnected or otherwise missing Wi-Fi cable due to the warranty that I do have on it as well as the Walmart one and I don't want to avoid anything if indeed it is possible to do so by opening it up... Is there anything I need to know, or can I open it up??? it's a newer model 15-in non-touch screen model of like the slate or stream or something like that machine with like an i3 in it, and the device itself works fast enough, but even with my phone sitting right on top of the keyboard with Wi-Fi hotspot enabled or in my church where I should get really good Wi-Fi and do get good Wi-Fi with everything else this thing gets no Wi-Fi whatsoever... It goes from literally no Wi-Fi to three bars of Wi-Fi and then back to no Wi-Fi when I'm within like 4 in or maybe 10 in of the Wi-Fi card depending on where I have my phone located in proximity to the laptop... I mean, hell... My desktop I just created gets way better Wi-Fi than that and it's built in motherboard Wi-Fi as opposed to an extra Wi-Fi card like this laptop presumably has... I'm not sure what kind of cooling it has, but I believe it's passive cooling as there doesn't appear to be much room in there because it's one of them thin ones that doesn't have a CD drive or anything, And it does appear to be a unibody bottom without any extra plugs or covers or anything for the specific components I think you just take the bottom off and then that gives you access but I'll have to check when I get home as to whether I can easily do that without voiding the warranty if there's no warranty stickers I might try it but I'll have to look up when iFixit guide to know exactly how to do it without breaking something

I forgot to mention, that it's been this way since I bought it but I just thought that it might be the device itself being poorly designed and poorly made until I seen on here that lots of people have that problem and a few of them have found that it actually is the Wi-Fi antennas being disconnected somehow or broken... Also, if that needs to be known I don't know but it was built in like 2019 I think...

Welcome to the HP Support Community.

Let's run a test:

1. Power off the PC and make sure that it is completely powered off.

2. Press the power button and the moment you press the power button immediately start tapping F2 key, you should see the system diagnostics screen.

3. Look for the component test, under that all the hardware will be listed, please choose Wireless module  and initiate the quick test.

Note: If it fails it will generate a 24 digits alphanumeric failure id, please capture that. 

Also. help us with your product number.

Let me know if this helps.
