I have a ReadyNAS 102, R8000 Router and Windows Surface PC - all running the latest OS versions.
I have had my itunes library on my NAS drive for years without any issues until the last few weeks.
Performance dropped to where itunes would freeze regularly and I am now getting problems copying any data/files over to the NAS and where I now get the 0x8007003B An Unexpected Network Error Occurred error.
I only get this issue when using wifi. When I am cabeled in to the NAS, it all works perfectly. Outside of the NAS issue my PC wifi is totally normal and runs things like general internet without any speed or connection issues.
My wifi is the 'ac' standard and Im connected to the 5GHz band.
Ive reinstalled the latest firmware on the router but that made no difference.
Online searching didnt really provide any answers - I have tried turning both the firewall and antivirus off but that made no difference.
All the indicators on the NAS admin pages show 'healthy' or are green
Unfortunately that doesn't mean that much. I suggest downloading the log zip file, as the mods would need that anyway. You can look at disk health in disk_info.log and you can also see network statistics in network_settings.log.
If you are running 6.9.4 firmware on the RN102, then I suggest upgrading it to 6.9.5. There were some bugs in 6.9.4 that resulted in connection timeouts.
Im running 6.9.5 on the 102 already. Ive extracted the full logs but it I dont know enough to know what I am looking for.
There was an interesting development though. I happened to have got a ReadyNAS 212 yesterday and set that up. I got some different behaviours depending on where the NAS's were plugged into.
I took the 102 off being plugged into the main router (an R8000 running the latest firmware) and onto a Range Extender (an AC1200 running the latest firmware) and the file issue stopped. The brand new 212, plugged into the main router, then started having the same file sharing issue. I then swapped the NAS around. The 212 that was plugged into the Range Extender then worked normally, while the 102 then went back to having the same issue.
So there is a wi-fi issue only when the NAS is plugged directly into the main router and accessed directly, but not a wi-fi issue when the exact same information is going through the same main router, to the same NAS, but via a secondary wi-fi device. That seems an unusual problem, but maybe more router related.

Was your WiFi Client connected to the extender, or was it connected to the router WiFi?
Either way, is the problem symmetric? That is, if the problem occurs when the WiFi client is connected to the extender and the NAS is connected to the router, does it also fail if the NAS is connected to the extender and the client is connected to the router?
My PC was connected via wifi to the router > router was connected via wifi to the extender > and the NAS was cabled into extender - in that configuration it works with no issue
PC was connected via cable to the router > NAS was cabled into router - this has no issue as well
PC was connected via wifi to the router > NAS was cabled into router - this is the config that has the issue
I get the unexpected network errors and/or very slow transfer speeds to the NAS (only fractionally better if I put a cable between the PC and extender)
I have ipv6
I dont have jumbo frames (ive only just found out what that means) but then this wasnt an issue previously - but there's no one thing (change, update, etc) I can recall that triggered this.
