Can a computer be *allergic* to a specific WLAN?

Question

Don't downvote or mfd just yet. 😉

What I am talking about is this phenomenon:

I usually work in a certain WLAN and my girlfriend in another. Now whenever I move my laptop to her WLAN, I get a lot of connection faults, while she has no problems whatsoever.

What's funny: If she moves her laptop to my WLAN, the very same thing happens, only inverted - I am fine and she gets kicked out all the time.

What can be the reason for that phenomenon?

Can you explain it in a way that I understand although I haven't done any real network or OS stuff with code yet? What's going on there, technically, in the background?

And how to tackle that sort of issue?

Answer 1

What happens if she works on your WLAN first and you join later. Who gets kicked out? You or her?

Answer 2

Thank you anyway, ~ swim ~!

Right now it seems to work for both of us (funny, these things), but as soon as the next disturbance comes up, we will try what you suggested, and I'll report.

Answer 3

So that probably rules out a capacity/bandwidth issue?

Answer 4

Sonic, I remember when I had the problem with her WLAN, that it was independent. I could be all alone in the sphere for the moment and would have problems anyway.

Answer 5

Sonic, well I would guess so myself.

Subjectively, it looks to me like our computers each took up a seat in their respective WLAN and somehow now defend it:

'I was here first, so beat it.' 🤣
