I'm just curious. Does the card was installed in the laptop by default?
If so what is the model of the laptop?

I observed quite similar issue on some rt2800 devices when
I applied this patch:
https://github.com/sgruszka/wireless-drivers-next/commit/846d205edd8c36d1b7828fee54bf4cf40bf8cb1a
It works on some devices and does not work on others with similar
symptoms - correctly associate but stop to work as soon as some
data traffic is performed.
So, I would check if send IEEE80211_TX_CTL_RATE_CTRL_PROBE frames
with qsel = MT_QSEL_EDCA would help.
Another thing to try is checkout vendor driver and see if there is need
to add extra code if device is_mt7612() .

No, I just buy this card on aliexpress and put into some dell (MTK
MT7612 2x2 half miniPCIE).

Do they sell dual-band version with ext amplifiers? I saw there is
5GHz version with 25dBm power modification...

Dual band is half version with lower power.
I also have full one with higher power - but works only in router
MT7621 (2xMIPS with HT - so, 4 cores - 880MHz).
My laptop PCI don't see this cards (some quirks probably for PCIE required?).
BTW, ath9k pcie works fine in MT7621 while ath10k not :)
Seems PCIE standard is "not the same" :)

Seems when data stall (iperf) and next reload driver, works much

patch improve hw (re)start.
Regarding iperf - as before :)
