Hi, wireless speeds almost don’t depend on the NIC , but rather on other variables such as the place of the router/access point, the building materials of the place you are in, whether you have a “Line of Sight between the access point/router” or the presence of devices such as microwave ovens, DECT phones or other wireless devices utilizing the 2,4 Ghz band.
also a note on the, the ieee 802.11b/g/n standard (a.k.a wifi)
ieee 802.11n has a theoretical throughput of 300 mbps, but has lesser penetration than ieee 802.11g
ieee 802.11bg has a lower theoretical throughput of 54mbps but has way better penetration,
so in a situation where the router/access point is far away. you may have faster WiFi with the ieee 802.11g (54mbps) than the ieee 802.11n(300Mbps) because ieee 802.11g travels better trough materials and thus loses way less throughput
so to put things together, the wifi speed is barely determined by the device itself, but rather by other things
I hope you find this information usefull
