Hi,
Im running FreeBSD nereid 11.0-CURRENT FreeBSD 11.0-CURRENT #0 r268622 on my laptop.
I am not able to get a decent network throughput when doing scp or ftp. Strange is no matter
what I use for transfer I get same speed: around 400KB/sec. Even scp or ftp ...
I tried to disable bgscan on the wlan0 interface, no success. See below, my settings:
1. device:
iwn0@pci0:3:0:0: class=0x028000 card=0x40608086 chip=0x088e8086 rev=0x24 hdr=0x00
vendor = 'Intel Corporation'
device = 'Centrino Advanced-N 6235'
class = network
2. interface

Any ideas if this chip is well supported or are there current issues with the driver for this device ?
Running Debian 7 on this machine let me to get 7-9MB/sec easily.
Thanks,
