Between my laptop and my server there is a WiFi modem and an ADSL
router and I think the comms is too slow. The device speed for each is:
Server: Intel 82567LF Gigabit: 10/100/1000 Mb/s
Belkin Wireless F5D7230-4v7: 10/100 Mb/s
Belkin ModemRouter F1PI241ENau: 10/100 Mb/s
Asus Zenbook UX31: ath9k: 54 Mb/s
RJ45 via USB: 10/100 Mb/s
and Cat5 cables.
On an unloaded network I can get about 6.5 Mb/s when I use the cable
connection to the laptop but nothing better than about 1.5 Mb/s for the
wireless connection - and even that is when the laptop and the wireless
router are only about 1.5m apart (the XFCE network icon shows connection
quality is then at about 90%).
Anyone know why the wireless performance is not better than this?
You could be hitting a a Atheros driver problem.
On my laptop I had to use the workaround below to correct horrible
wireless performance.
I am not familiar with what can be done your system so YMMV.
03:00.0 Network controller: Atheros Communications Inc. AR9285 Wireless
Network Adapter (PCI-Express) (rev 01)
Subsystem: AzureWave Device 2c37
Kernel driver in use: ath9k
Kernel modules: ath9k
WORKAROUND:
rmmod ath9k
modprobe ath9k nohwcrypt=1
echo "options ath9k nohwcrypt=1" > /etc/modprobe.d/ath9k.conf
