Hello, I have some laptops and servers in my WLAN/LAN, all connected to the same router and same subnet 192.168.2.x; they all run the same 12.0-CURRENT r314251 amd64: The following NICs are involved: Acer C720: WLAN ath0: AR9460 mac 640.2 RF5110 phy 2456.12 Dell e6330: WLAN rtwn0: MAC/BB RTL8188CUS, RF 6052 1T1R Dell r210: LAN bce0: <QLogic NetXtreme II BCM5716 1000Base-T The transfer rate between them for a gzip'ed file transfer with scp are: r210 --> C720 1.7MB/s e6330 --> r210 1.8MB/s but: e6330 --> C720 120KB/s, ... 30KB/s What can I check to resolve the poor rate from the e6330 to the C720? The other direction i.e. from C720 to e6330 is fine. Thanks matthias -- Matthias Apitz, ✉ guru@unixarea.de, ⌂ http://www.unixarea.de/ ☎ +49-176-38902045
