I tried it on 802.11a and all works fine. I measured bandwidth with various threshold. On 802.11a speed was smaller with smaller threshold, but with 802.11n nothing happened. Speed was still the same even with threshold set to 256 bytes. Configuration was same as when I measured bandwith on 802.11a.
I'm using RB411 with R52n cards.
Thanks for the help. (Sorry for my english
)
