I upgraded from FreeNAS 9.10.2-U6 to 11.1-U4 just under a month ago. After that, I started experiencing bandwidth issues when streaming from a PLEX media server, and file transfers started taking an unusually long time.
I did a speed test with iperf, and found that I was only getting around 94 Mbps.
I then checked the configuration with ifconfig, and it showed that the interface was only at 100baseTX:
igb0: flags=8943<UP,BROADCAST,RUNNING,PROMISC,SIMPLEX,MULTICAST> metric 0 mtu 1500
options=2400b9<RXCSUM,VLAN_MTU,VLAN_HWTAGGING,JUMBO_MTU,VLAN_HWCSUM,VLAN_HWTSO,RXCSUM_IPV6>
ether 0c:c4:7a:78:56:16
hwaddr 0c:c4:7a:78:56:16
inet 192.168.1.10 netmask 0xffffff00 broadcast 192.168.1.255
nd6 options=9<PERFORMNUD,IFDISABLED>
media: Ethernet 100baseTX <full-duplex>
status: active
When I manually tried forcing a gigabit connection using "ifconfig igb0 media 1000baseTX," ifconfig would show that the "media" entry changed to 1000baseTX, but it would no longer connect - the lights next to the jack went dark. As soon as I set it back to 100baseTX with anouth ifconfig command, the lights would turn on, and the network connection would restart.
I'm using a Supermicro X10SLL+-F. From the output of "pciconf -lv" it seems that the driver is okay since the system is recognizing a gigabit connection.
igb0@pci0:3:0:0: class=0x020000 card=0x153315d9 chip=0x15338086 rev=0x03 hdr=0x00
vendor = 'Intel Corporation'
device = 'I210 Gigabit Network Connection'
class = network
subclass = ethernet
igb1@pci0:4:0:0: class=0x020000 card=0x153315d9 chip=0x15338086 rev=0x03 hdr=0x00
vendor = 'Intel Corporation'
device = 'I210 Gigabit Network Connection'
class = network
subclass = ethernet
Any ideas on how I can get this system back to a gigabit connection?

I have now.... How embarrassing. It didn't occur to me that the cable could go bad for no particular reason, so I ended up wasting my time writing the question instead of swapping out the cable. At least I have my transfer speed back. Thanks for your help!
