?
Thanks in advance

If it's a 54mbps Wi-Fi card, it will only be B or G. N is a helluvalot more faster than 54mbps.
802.11B has a maximum theoretical bandwidth of 11mbits/sec
802.11G has a maximum theoretical bandwidth of 54mbits/sec
802.11N has a maximum theoretical bandwidth of 300mbits/sec.
The actual (practical) throughput is realistically maybe 2mbits/sec for B, 15mbits/sec for G, and depending on hardware, ~100mbits/sec for N. These are *really* rough numbers since actual throughput depends very heavily on hardware.

The bandwidth requirements for streaming HD media pretty much require that you have 802.11n in-place. 802.11G's practical throughput is borderline for streaming HD... Just the way things are...
