ReadyNAS 102: network link is 100 mbit instead of 1000 mbit (gbit)
Hello!
ReadyNAS 102, Firmware: 6.9.5
Today I had found that large data from my nas ReadyNAS 102 is copied with the speed about 8-9 Mb/s, so it is exactly equal to the LAN = 100 Mbit (Mbps) instead of 1000 Mbit (Mbps) (1gbit). I can't say exactly when this had occured, because mostly I had worked with a small files and rarely, so if it was about 8-9 Mb/s (instead of 60-80 Mb/s) - it was enough.
On the rear panel of my ReadyNAS 102 I see two LEDs. The left one (green) is off, and the right one (yellow, amber) is blinking. As I see in documentation of ReadyNAS 102 it means, here is a quote:
Two LED status indicators are built into this port, one green and one amber. They
indicate port speed and activity as follows:• Green on, amber off. 1000 Mbps connection speed, no activity.• Green blinking, amber off. 1000 Mbps connection speed, activity.
• Green off, amber on. 10 Mbps or 100 Mbps connection speed, no activity.
• Green off, amber blinking. 10 Mbps or 100 Mbps connection speed, activity.
• Green off, amber off. No connection.
So, it is actually means that I have a connection for a 100 Mbps instead of 1000 Mbps. But... why?
In the admin panel of the ReadyNAS 102 I see:
Name: eth0 Bandwidth (Mbps): 1000 MTU: 1500
Here is a some log after ReadyNAS 102 restart:
Feb 24 00:33:10 NASHOST kernel: md: md127 stopped.

I think words "ethernet eth0: Link is Up - 1Gbps/Full - flow control rx/tx" means 1 gbit.
So... why?
I had connected my ReadyNAS 102 as experiment directly to my notebook with another one cable (just to be sure, that there are no issues with the switch and/or with the cable). What I see? In the Windows "Network Connections", adapter status (connection status) it is written as "1 Gbit". On the notebook network card I see left green LED is on, and right yellow (amber) LED is blinkg - that is mean really 1 Gbit connection. But ReadyNAS 102 rear panel network card's LEDs are the same: left green LED is off, right yellow (amber) LED is blinking, what is mean the 10/100 Mbit connection. And, of course, copying files from ReadyNAS 102 to my notebook (.avis and other large files, etc) - 8-9 Mb/s as 100 Mbit connection.
Here is some other log from NAS:

Any ideas what to do?
What is may be?
Is network card in NAS partially damaged/corrupted, so it works only as 100 Mbit instead 1000 Mbit?
Please help me to understand the issue and fix it if possible.

It's odd that the LED status is out-of-sync with the logs.
I'd begin by rebooting the NAS, and then try a different ethernet cable.
The NIC in the ReadyNAS can't be repaired - so you might also want to check your warranty status. The hardware warranty is 3 years for the original purchaser (and is not transferable).

Yep, it is strange.

I had wrote that I done all of this. I had shutted down the NAS, removed AC cable to be sure that it is really powred off, and then booted it again. The same. :(
I had used another ethernet cable and connected NAS directly to the notebook (more details are written in my first post) - the same behavior :(

That's very strange, because it just a common NIC, as I understand. Or it is totally embedded to the NAS motherboard?
Warranty is expired, because I bought that NAS at 2015 or something. :(
Thank you.
The NIC is embedded. There are no replacement parts available for ReadyNAS products. Even if you have the soldering skills and equipment, the part is not readily available in single quantities from any source.
It does sound to me like your NIC is faulty, though just a bad connector is also a possibility. I have a Duo V2 that does the same thing that was damaged by a power surge.
