0x8007003b unexpected network error when transfering large files.
can send/recieve small files
can recieve large files
cannot send large files
Network setup is a bridged wireless connection. Router A (WRT3200acm) is connected to modem and RN314 via cable, Router B (WRT1900acs) is connected to pc via cable. They are wirelessly bridged togather, in this configuration I am unable to transfer large files to RN314. If i disable the wireless bridge, and enable the nic card I can transfer files fine.
I have tried the AVG on/off, firewall on/off, and file search on/off.
Any input would be appreciated.

I think it's pretty clear that this is a network issue (the bridged connection has to be dropping), since moving to wired ethernet resolves it.
So there's nothing you can do in the NAS to fix it Options include
fixing the bridged uplink somehow (move the extender closer to the router, try a different extender, switch to 2.4 ghz, ...).
switching to a different technology (for instance powerline or a mesh router. Or run ethernet and use router B as an AP).
moving the NAS to router B. Then there will still be issues when accessing large files from router A, but not when you are accessing the NAS from router B.
I don't believe its dropping really, as stated I can move files from RN314 to PC just not the other way around. Also the NIC card I am referring to is wireless.
Then please clarify the network path that works (what PC NIC you are using, what router it is connecting to, etc), and also the network path that fails.
For instance something like PC (ethernet) -> Router B (wireless) -> Router A (ethernet) -> RN314 fails.

It HAS to be the network connection path, since changing to a different path resolves the problem.
PC (wireless) <=> Router A (wired) <=> RN314 /=/ Works Small and Large Files in both directions
RN314(wired) => Router A (wireless) => Router B(wired) => PC /=/ Works Small and Large Files
PC(wired) => Router B (wireless) => Router A(wired) => RN314 /=/ Works Small Fliles, Does Not Work Large Files
This combination suggests that you are getting connection drops when router B transmits a lot of data to router A. Likely shorter file transfers will also fail sometimes, just not as often as longer the longer files transfers do.
Note the connection performance isn't symmetric, because Router A and Router B aren't the same (and router A is higher end).
One test would be to move router B fairly close to router A (perhaps 6-10 feet away in the same room), and try PC(wired) => Router B (wireless) => Router A(wired) => RN314 again. If it passes at closer range, then that confirms that the wifi bridge link is the problem.
Another useful test is to try PC (wired) <=> Router A (wired) <=> RN314 in both directions, using the same cable you use to connect the PC to router B. If that passes, then it rules out the PC NIC and the ethernet cable.
Router A and Router B are approximatly 40 inches away currently. I have a project (unrelated to RN) that requires real time data streams. I switched to the bridged connection because of its reliablity compared to the wireless card which would drop several times an hour. I chose the bridge over a cables due to the fact of needing a switch anyways and not wanting to run cable or put holes in the wall, plus the router was laying around from a previous project. I can plug another computer into Router A and pump 1TB of data into it from PC at router B at 100+ MBPS.
Im not saying that it is specifically a RN problem but its seems to be the only thing giving me problems currently.
Additionally i can confirm:
PC(wired) <=> Router A(wired) <=> RN314(wired) /=/ Small and Large files
PC(wired) <=> Router B(wired) <=> RN314(wired) /=/ Small and Large files
So all paths exceptPC(wired) => Router B (wireless) => Router A(wired) => RN314 work with both large and small files.
And PC(wired) => Router B (wireless) => Router A(wired) =>PC2 works for sustained transfers, which complicates the wifi link theory. You say you are getting sustained throughput on this test of 100+ megabytes per second? Or did you mean 100+ megabits per second? I am guessing the latter, given the normal 5 Ghz performance of the WRT1900AC
Can you try reversing the topology? That is, RN314 (wired) <=> Router B (wireless) <=> Router A(wired) <=> PC
Correct, its only the 1 specific path that will not function in 1 direction with large files.
Also Correct when targeting a 2nd PC I have very reliable transfers, 100+Mbps, can do ~60MBps max if im targeting flash or ssd drives on the network if there is low traffic, most spinning disks on an OS do ~35MBps when transfering. Additionally I have targeted both linux and windows machines.
I have an end of cylce in about 10 hours, i will switch the routers then and see if that works any differently and report back.

Based on review performance measurements (here: https://www.pcmag.com/article2/0,2817,2457039,00.asp ), the WRT1900AC is capable of about 110 megabits per second over wifi (which would apply to your bridge link). That's about 13 MB/s. 35-60 MB/s is consistent with wired gigabit (though slow for an SSD).
Very interesting, im not sure how this exactly effects the particular situations seeing as even 1kbps should eventually allow me to transfer files from PC to RN314. However if it is numbers you are interested in, it would help to look up the correct router, and an article that is not running almost 4 year old firmwares.

Sigh.... Yes, I accidently left the s off the router name. But your router B still can't do 100+ megabytes per second on its wifi link, it's about half that (500 mbits at best). So if you are measuring 100+ megabytes/s sustained performance on the path through the wifi bridge, then something is wrong with the test.
I've been taking a fresh look at your scenarios to try to understand them. Some of the info you are sharing might not be relevant, but still I'm trying to make sure I understand everything you are telling me.
No go on the switch, same results regardless of router position.
Minor update, when transfering files now to RN314 the file appears on RN314 but it is not actually there. For instance if i transfer a video it appears, all of its information appears, however it is unable to stream unlike videos already on the RN314.

Which means that the PC -> NAS transfers fail with both topologies, correct? And NAS -> PC transfers work with both topologies?.
That makes me wonder about ethernet flow control. Check the PC ethernet NIC driver settings, and see if there is a setting for flow control (sometimes known as 802.3x, or ethernet pause frames) in the NIC driver settings. Make sure it's enabled in both directions (though tx might be the more critical one).

Already been though most of the nic driver settings, additionally been though the last few driver revisions. Stream with VLC to PCs, DLNA to some media devices.
Seems to be working now, transfers speeds are down approximatly 30% to RN314 but at least it is working.
Solution was shutting down entire system and restarting Router A > Router B > RN 314 > PC, then all other devices connected to the system. Any other order would for some unkown reason to me would cause the failure.
