Connectivity TS451+

[dbits]

Hi,
on Sunday I recognized that there is a new firmwareupdate - 5.2.0.2860 - available, actual 5.1.8.2823 is running.
I notice that the TS451+ made a restart without ending the services. After 15 minutes looking at the running wheel I turned it off, after a few minutes I switched it on again.
I was unable to get a connection to the Qnap either web nor win explorer.
I found out that NIC1 is dead, connecting to NIC2 is possible router gives a new IP, QfinderProshows my TS451+ shows an entry - but no chance to access my data.
The router shows a different MAC (NIC2) as Qfinder (NIC1).
TS451+ is EOL - do I have a chance to repair the device? Or just throw away?
thx
Dieter

I'd say that repairing on-board ethernet ports isn't worth the effort on an old TS-451+ but you should be able to recover and access your data over the working ethernet port.

Are you using the admin account? If so, did you notice this in the release notes when reading them prior to updating. "To enhance the security of your device, the default password for the system administrator account "admin" has been changed to your device's Cloud Key. For details, see this FAQ: https://www.qnap.com/go/how-to/faq/con_show.php?cid=2288".

If you have tried admin login with an older password, your client system may have been locked out due to failed attempts. Then change the IP address of the client to bypass the lockout.
