Hi all,

I'm running into a weird issue with my AirPort Extreme. Tonight, I transferred a 6GB file from my file server (with scp) to my 2010 i7 MBP over 802.11n, and got only ~15MB/sec:

1691_20100625003000.mpg 100% 6350MB 14.8MB/s 07:09

When I tried to transfer a file from my MBP to the server, I get almost 22MB/sec:

test.bin 100% 500MB 21.7MB/s 00:23

(on wired, I seem to get ~45-50MB/sec in both directions)

The other weird thing I noticed is that when I flood ping from the server to the MBP over WiFi, I get packet loss, while I get 0 packet loss from the MBP to the server:

Code:
--- 10.0.1.5 ping statistics ---
1273 packets transmitted, 1000 received, 21% packet loss, time 4169ms
rtt min/avg/max/mdev = 0.571/0.877/6.687/0.556 ms, ipg/ewma 3.277/0.633 ms

--- 10.0.1.253 ping statistics ---
4516 packets transmitted, 4515 packets received, 0.0% packet loss
round-trip min/avg/max/stddev = 0.520/0.718/5.999/0.327 ms

Transmit speed according to my MBP is 300mbps. Does this look reasonable at all? I'd think that there'd be no packet loss in both directions when flood pinging, at least. Thanks!
