Hi, I am not having full speed in an attached USB 3.0 external hard drive using this release in a Linksys wrt3200acm, here is a measure:
root@OpenWrt:/mnt/sda4# time dd if=/dev/zero of=tempfile bs=1M count=1024
1024+0 records in
1024+0 records out
real 0m 26.26s
user 0m 0.00s
sys 0m 4.01s
Which is more or less 39MBps and according to this link my hardware is capable of 100MBps write speed on USB 3.0.
Maybe drivers are buggy?
P.D. this same external HDD on my desktop PC have 100MBps write speeds normally.
Since I reset the WiFi country code settings to default US a month ago my ZyXEL NBG6817 has been running uninterrupted without any major issues. The 5GHz radio module has rebooted once and switched from channel 48, for which it had been configured, to channel 100. I also found this in the kernel log afterwards:
