Can not connect to any 5GHz networks.

seth · 2024-09-24 21:13:27

From what I can remember, my prebuilt PC never came with an antenna stub.

It does look like the posted picture?
These things *need* to have an external antenna.
It's either a stub you plug into the wifi card or build in and hidden under some plastic of the case (but still needs connection to the wifi chip)

How close is the system actually to the AP?
Have you tried turning it by 90° / 180° / -90° (yes, 270° but you're probably running out of cable in that direction

Edit: and just to pile up on that, the 5GHz band is much more sensitive to this than the 2.4GHz one - if the box isn't 15m, 4 rooms and one storage away from the AP, it's the cases EM shielding.

Just opening it ***might*** improve things just about enough.

I'd agree, but unfortunately I live with people who are against having a cable run across, even if I'm close to the router, they still are against it.

well - I AM aware I have no rights to write the following - but I can't find any other words for this than: "some stupid people just can't be reasoned with" - and hence calling this "being against running yet another cable" just "being stupid"
to at least try to give some "justification": there're already at least three cables: power for your pc, power for the AP, network for the AP - why would it be such a problem to run one additional cable along the power cable to the socket your pc is plugged into, along the wall to the socket where the AP's power is plugged into (which, if both very near, could be the same) and run it along the AP's power or network cable (which also has to be plugged in somewhere at the other end) - I'm actually curious about the reasoning of the people you live with about this idea - as you pretty much hide the network cable along already existing runs of other cables
I would understand if you would run it just straight in about 1,50m height straight across the room - but running it along other cables and he edge of the floor? come on - what kind of people are you living with not accepting THAT but instead let you suffer from your wifi issues? if a 20 bucks patch cable really is that kind of a big deal you really should reconsider if living with those people any longer is a good idea

Well, yes. My computer is and does look exactly like the one in the image *duh* but I never had an external antenna, it just worked out of the box for a few months and then the 5GHz broke.
So my 5GHz always worked until now, I don't know what happened, nothing changed. I never used an external antenna, any other wifi items, nothing. It just stopped functioning properly.
Rotating the computer doesn't help, Seems like a hardware issue on my end. I don't know.

I think "people" is "wife" "parents" and the router isn't necessarily anywhere near the next wall outlet or the monitor.
That being said, you can cast a 20m cat6 cable, covered, along the wall/floor corner.

@Calowed
The BIOS could be used in various systems - do you have an alternative AP, eg. a smartphone hotspot?
Edit: let me stress, if we're talking about -65dB over 3m distance to the router and the wall isn't full of asbestos, the antenna is missing or broke.

I live a room away from the router. I moved the PC to the room to see if it was because of the distance, it was not. I think that's why they don't let me run ethernet since the cable would be in the open, even if it ran against the wall.
And 5GHz connection worked even from my room to the router, so I doubt it's a range issue. All variables are the same. I could connect to 5GHz from my room, now I can. Nothing has changed besides the storage on my linux partition, that's when the wifi issue happened.
I can't not live with them either, as I am a young fella and living on my own would be impossible

Yes.

I tried to connect to my mobile hotspot, but still no luck, I dont think its a router thing.

I am connected to my 5GHz network on my phone right now, and I can not connect on my computer. I can not connect to my 5GHz Hotspot either.

Likeliest conclusion I can come to is that this is a hardware issue, I believe that my wifi card just... broke...
Maybe my fault, maybe not, but likeliest outcome is that I broke it by doing something stupid with linux. I haven't tinkered with the physical computer at all.
So either I made a bad decision on linux, or this situation is out of my control.
And to be clear, my walls are not filled with asbestos Probably meaning my antenna is broken

seth · 2024-09-24 21:59:37

You'll rather not be able to physcially break the antenna in linux (or any OS) so that windows is likewise affected…

Have you looked inside the system to see whether there's an antenna connected to the wifi chip?
It's supposed to look like this, https://i.pcmag.com/imagery/reviews/04d … _1050x.jpg (at least from a generic search result) and the antennas would go out to the board side of the case where you'll likely find a plastic sheet w/ a thin wire spirale (though not really round) attached to those cables.

Edit: just because it has initially worked doesn't mean it hasn't always been broken like this - just that something about the environment (could be humidity) changed that tipped the scale against your favor.

Yup, looks exactly like the photo you sent.

seth · 2024-09-24 22:33:59

If the cables look ok and are attached, the issue is gonna be on the other side - can you remove the outer wall of the case on that side?

I'm not too comfortable doing this myself, I'll ask my brother or something to help out. Is there any other option I can consider in the meanwhile?

cryptearth · 2024-09-25 03:55:12

well, if it's a pre-built and it not came with the accessories the hardware original arrived with at the oem you just got scammed and you should report this both to the public and the oem support
as for the cable ... well, some people ...

seth · 2024-09-25 07:14:12

Add

pcie_aspm=off

to the kernel parameters, but with windows affected, any kernel configuration is increasingly unlikely to do anything.
You could reset the CMOS, but if that causes any trouble that's usually not a weak signal or handshake timeouts, but the chip not responding at all.

Do you still have an old journal from when the system was in the room w/ the AP?
(you can access older ones by passing negative values to "-b", eg. "journalctl -b -3" is three boots ago)

I have logs which date back to when the 5GHz network did properly function. Would you like me to send you those instead?

seth · 2024-09-25 20:12:13

Ideally post both (I assume you moved the box afterwards)
Or, if you can, connect it to a smartphone hotspot in the same room.
You want to know whether the signal is poor-ish even though the AP is in immediate proximity because then the problem is the EM shielding of the case.
Just openening it should™ improve the signal to an AP that's facing the open side.

Nevermind, turns out do I not have those logs. And yes, now I am 100% confident it's something with the wifi chip.
My wifi chip comes with the bluetooth too, and I can't use bluetooth anymore unless it's a 2.4GHz connection, or I use a dongle.
The hotspot possible solution however did not work, it seems as there is something pretty wrong....
sorry for the radio silence the past few days, been very busy with life.

seth · 2024-10-01 19:04:31

Bluetooth exclusively uses the 2.4 GHz band. There's no 5GHz BT.
But both will likely use the same antenna.
Did you have any chance to inspect its physical condition inside the case and also the part on the outer wall?

The hotspot possible solution however did not work, it seems as there is something pretty wrong....

What exactly does this mean? Do you have a journal of that run? (Notably, how's the signal to the hotspot?)

I did not get the chance to inspect it yet, I thought I had the journal but I do not. Also the hotspot doesn't work either, the signal is amazing but it just wont connect.
And now, I've ran sudo pacman -Syu and now my xorg is broken
Any possible solutions? I upgraded my kernel and my nvidia-lts, that's probably the culprit but I dont have any ideas on how to fix it.

My apologies. That fixed my problem, thanks.
I'll get the hotspot attempt in a moment, I have people over at my place. I'll keep you updated.
