I don't know why this is happening, but whenever I have even a small file transfer from this machine to the wired computer (only other machine on the network), my RX rate drops to 7mbps and constantly fluctuates between that speed and normal (240-300). It's also drops to 7mbps once in a while (once in 20sec) even without any data movement. The TX rate is always stable. Why is this happening? I've switched from N to G because of this, but will need full throughput again soon.
