Network error after firmware update

English Networking
1

Hello to everyone, I’ve a TS-251D, and a few days ago I updated the firmware to the following release : 5.2.8.3332.

I didn’t notice any errors during the update, and then I leave the office till today, where I notice that the NAS was not reacheble from my PC. I checked all the usual errors (network cable, firewall, antivirus) but all was exactly as I leave the NAS after the update.

The strange things is that if I unplug the cable for few second, and I connect again the same cable, Qfinder Pro, find the device, but any action after that give an error because is like the NAS was disconnected, in fact if I run again the search, it didn’t find the NAS, until I unplug again the network cable.

I changed different network cable, but the resul was the same.

Question:

  1. is it possible to connect the NAS without network?

  2. Is it possible to do a factory reset without lost the data in the driver?

Any suggestion/idea is appreciate

The first thing to check in Qfinder Pro is if the IP address of the NAS is in the same subnet range as the IP address range of your network.

Double check that first please.

Yes, you can connect directly, if you set a manual IP address.

Yes, you can do a reset without losing data (but you should always have a backup)

The IP address is correct (PC - 192.168.XXX.AAA; NAS - 192.168.XXX.BBB) while the Subnet I know the PC one, but I don’t know the NAS one, because I don’t have access.

I tried to connect directly the network cable to the PC, as explained in the report linked, but the Qfindpro it doesn’t find any

OK. So you can do a 3 second reset and that should reset the admin password and your network settings. The NAS will then get an IP address from your DHCP server and then it should show up in Qfinder.

Hi NA9D, I’ve an update; I tried to connect the NAS through the internet (MYQNAPCloud) and is reachable and usable (I download a file)so the network card works correctly; I suppose the problem is the PC, now I’ll try to install Qfinder pro on another PC and make some tests with it.

I keep you updated

You should not even need to use QFinder Pro. Just try accessing the NAS at it’s IP address and port 8080:

http://192.168.0.1:8080

I’ve seen issues where Qfinder never finds a NAS!

It could also be the default firewall (on the NAS) setting (and/or whitelist) that got installed/updated during the firmware update.

FIXED! Yes, it was the NAS Firewall that blocked all the inbound connections. Thanks for the desktop connection through MyQNAPcloud, I was able to update the firewall app, and find that all the connections from my network were blocked (I don’t know why). I need to put more attention when I update/change the configuration.

Many thanks to NA9D and dosborre for yours support :grinning_face:

May I ask why you are evening running QuFirewall? Unless your NAS is exposed to the internet (why? It should not be…), there is no need for it.

…you are right, it was my mistake; after the firmware update, I checked if everything was good, and I noticed the firewall was not active, so I activated it without thinking too much…

BTW, it was good to check all the rest and test the recovery plan (thanks all the other backups I put in place).

Thanks again for your support
