Wireless performance/speed increase?

Hello!

Are there any ways of improving wireless performance/speed? Now I get 3MB/s from my router/NAS box working on FreeBSD 8.0. Could someone give my advice in which direction to look for?

Thank you!

802.11g.


Wireless card is:

I have tried dturbo mode, but interface wont go up with this option in rc.conf.
 
802.11g has a theoretical max throughput of 56 Mbits/sec, or about 7 MBytes/sec. Actual throughput depends on several factors: distance from access point, strength of the signal, radio interference, number of clients connected to access point, etc.

If you are getting a solid, consistent 3 MBytes/sec, then you have a good, clean connection to the access point, and I wouldn't be complaining. :)

There's really only 1 way to get faster throughput on wireless: buy a faster access point (Atheros SuperG 108 Mbps 802.11g or 802.11n) and a matching wireless adapter. SuperG bonds multiple 802.11g channels together to achieve a theoretical max of 108 Mbites/sec, but requires SuperG-capable radios on both ends. 802.11n has a theoretical max throughput of ~480 Mbits/sec.
 
I have Atheros SuperG card on my router box, but I use at home only laptops so it means that I have to change all wireless cards on them. It is really painful! I'm thinking about switching all adapters to 802.11n, but little bit later. So that's why I am asking advice for any software based tweaks to improve wireless performance. I thought maybe someone done something like that.
