high power mini PCIe wifi cards?

I'm using MikroTik RB2011UiAS-2HnD-IN as home router. It allows 1000mW emission power and i guess it's pretty fine considering its signal is outperforming in terms of SNR (signal-noise-ratio) all other networks in my flat (-60 dBm outdoor, about 200m from my block of flats comparing to -85dBm from basically all other networks around). Well this router is also available in U1 rack-mount chassis so i guess it could be considered server-grade hardware, I really doubt there's problem on this side.

So I guess the problem is weak laptop network card (especially phone network card seems to be a bit more stable than laptop). I usually experience unstable pings with Intel Centrino N 6235 and audio streaming to remote soundcard over pulseaudio isn't really comfortable, there are noticeable packet drops etc. So I've decided to look for some... more serious wifi card, to match this router and basically smash all the noise in flat on 2.4 Ghz plus provide nice range (like 500m or something)

I thought about something like this:

I found that there are linux drivers for this chip so it should work under linux in terms of software I guess. But the point is - will it work in laptop at all as in hardware? I mean - i have half-size PCIe slot (Clevo W110ER), but I've measured that after ripping off some parts of chassis and cutting hole in backplate to make space for radiator and isolating few metal capacitors bodies which will have physical contact with adapter PCB I'll be able to fit this card physically and probably it won't even blow up motherboard.

But on the other hand... Maybe there are already more... laptop suited 1000mW wifi cards? Which won't require ripping off half of laptop body to fit cooling system?

I mean I have packet drops when I sit literally 1-1.5m in straight line form router, so i don't think antenna would help, when I'm scanning wifi signals at home there are tenths of networks around with still pretty strong signal (-65dBm, my router -30dBm) so i think it might be noise? Or bad quality wifi card in general. I have ping drops sometimes to about 12ms whereas i need 0.5 - 2ms stable during audio transfer because 12ms causes noticeable hiccups in audio stream and video streams.

Hard to tell, phone is a bit more stable but also experiences hiccups however less often. But i don't have any other good quality wifi device at home.

Basically 90% of connections at my home are gigabit connections over wire, this router can route 1.6 gbps at once and all devices are connected using them. I don't have such issues when connecting over gigabit wire but I'd like to achieve similar latency and stability as using wire so I think i need pretty tough piece of hardware in order to achieve that. Enterprise routers allow wireless bridging (so does this mikrotik) so I don't think it's impossible to achieve super low latency wifi with enterprise grade hardware
