Here are the results if someone can help me analyse the situation:
My setup- Raspberry Pi (512MB. Brand new) connected to a 54Mbps router. The "server" where I want to stream files from is my laptop, and it is connected via wifi to the router (since laptop-router connection is proven sufficient to stream at least 720p as tested with stand-alone streamer Sony SMP-N200 which was also connected via wifi to router).

Did 2 tests for Pi-router connection,
1st via wifi connection to router using dongle Edimax EW-7811Un (150Mbps):

Terminal

[216] local 192.168.0.2 port 51391 connected with 192.168.0.4 port 5001
Waiting for server threads to complete. Interrupt again to force quit.
[ ID] Interval Transfer Bandwidth
[216] 0.0-50.0 sec 42.8 MBytes 7.17 Mbits/sec
[180] 0.0-50.2 sec 9.63 MBytes 1.61 Mbits/sec

2nd via ethernet connection to router:

Terminal

[212] local 192.168.0.2 port 51472 connected with 192.168.0.4 port 5001
Waiting for server threads to complete. Interrupt again to force quit.
[ ID] Interval Transfer Bandwidth
[212] 0.0-60.0 sec 105 MBytes 14.6 Mbits/sec
[176] 0.0-60.2 sec 20.6 MBytes 2.88 Mbits/sec

Are these sufficient to stream 720p or even 1080p?
If so, why isn't the XBMC client able to stream them smoothly and keeps buffering?
If not, what can I do to speed this up?

Thanks.
