I live in a pretty crowded building, so the "airspace" is pretty crowded as well.
I get internet from FTTP through a 1Gbps link, which can be considered as stable and reliable for my question. Please consider only the WiFi aspect.
I currently have a higher bandwidth when uploading than when downloading (according to various speedtest services, and it's pretty consistant, about 2x more).
Here's various results from speedtest.net:
The last row is a wired result, just for reference.
Are my upload rate higher because my laptop antenna is just more powerful? Or is there other possible reasons?
My Intel 7265 chipset is supposed to have symmetric bitrate: https://wikidevi.com/wiki/Intel_Dual_Band_Wireless-AC_7265_(7265NGW) (2x2:2)
The router seems to have symmetric bitrate as well: https://wikidevi.com/files/Marvell/88W8366.pdf (3x3) (but only two antennas anyway)
EDIT: upgraded my AP with an Unifi AC Lite:
In conclusion, I guess the original router just shipped with the crappiest WiFi card/antennas/config and did not emit a strong enough signal.
