readynas mapped drive keeps disconnecting
Hi everyone, I have a readynas 312 running os 6 and I have an issue where mapped network drives to the readynas constantly disconnect. Even while using a file I'll go to save it and it won't allow i...
yes gigabit ethernet connection from Nas to switch and then from switch to computers. I will try later today switching the ethernet wire and port with the one from the server it replaced to see if there is any difference

Sounds like a good next step. If that doesn't help the packet loss problem, then try a direct connect between the PC and the NAS. You'll need to set up a suitable static IP address on the PC (if you use dhcp, the NAS will fail over to 192.168.168.168 ).
switched the ethernet cable and port and still getting dropped connections. Haven't been able to test it directly to one computer only as others in the office need to use the files. Is there a setting or reason that may cause dropped packets? There was never a dropped packet issue before when using the windows server.
Thank you
would switching to or adding a second ethernet connection to the nas help?

If packets are queuing up in the switch, they eventually get dropped. Turning on ethernet flow control in the PC clients can help (also if the switch is managed, there is a flow control setting there too). Usually this would only show up as an issue if there are some fast ethernet connections on the path. But if you have multiple users writing to the NAS, then you could overrun the switch buffers.
If the MTU is set too high, then oversize packets either are discarded or fragmented. For instance, if the NAS is set to use jumbo frames and the PC clients use a smaller MTU.
If the NAS thinks the connection is full-duplex, and the switch thinks it is half-duplex (or vice-versa) you will see packet loss also. That's fairly rare now, but was more common ~10 years ago.
There are of course physical causes too (wrong grade cable, a marginal connector, a failing NIC card).

Simply adding the second ethernet probably won't help (and you'd need to set up NIC bonding).
Moving the cable to the other NAS ethernet port is worth a try - similar idea to trying a different port on the switch.
I think I've ruled out the cable since it still is having connection issues after replacing with another cable. I haven't messed with MTU settings they're still at 1500 and when I tried pinging I had no packet loss. We have a few users using the NAS at a time but they're not all writing at the same time always, and it's usually only small word documents being used.
Any ideas on solving this? We're using the same switch as with the windows server and never had any connection issues on that. Trying not to return the product, but can't keep operating with all these disconnects.
Thank you
