RN104 Slow Read Speeds
Hi, I have a RN104 with the latest current version of OS. If I transfer files from a Windows 10 PC (connected via 100mb, NAS is connected to router via gigabit) I can write to the readynas at fu...

Anything I can check to get better read speeds? 4MBps is really not very good.
Do you have jumbo frames enabled on the NAS? If you are mixing gigabit with fast ethernet you shouldn't turn them on.
Also if you have both NICs connected on the RN104, try disconnecting one.
Can you test speeds with NASTester (http://www.808.dk/?code-csharp-nas-performance)? SMB performance depends on file size, so it is sometimes good to measure performance with a tool.
A direct connect test (as BrianL suggests) is also a good idea. You need to temporarily assign static addresses to the NAS and the PC. Then run ethernet directly between the NAS and the PC- bypassing routers/switches. (no crossover is needed).
This NAS also refuses to be accessed when using NTLMv2, but I can get around that by editing the registry to 'Send LM & NTLM responses, use NTLMv2 session security if negotiated'. Which while it works, is annoying that any new windows 8 or 10 machine I set up to use this has to be maually edited just to access a simple network share.
I didn't need to make any registry changes when I upgraded to Windows 10 (NAS firmware is 6.2.5). There is an SMBPlus app that Netgear provides that will give you more setting controls on the NAS side. Try installing the app, and reversing the registry changes.
Brian's article is for Vista, so I don't think it's relevant here. Clearly Windows 10 has no problems with current SMB.
Thanks for the replies.
The NTLM issue - it has been happening with windows 8 machines and now windows 10. I can't find any settings to manage that on the nas. The SMB plus app only allows me to select which version of smb it uses. That kb article is the setting I need to change but I fail to see why I need to modify every windows 8 or 10 machine in order for it to access the shares. I also have the shares set to anonymous access but it still also prompts me for username and password the first time I try and access the shares...
With regards to the slow read performance, I have narrowed it down to this machine, and only for read operaitons from the nas. For example, I can download from the NAS using a laptop on wifi ac at 50MBps. On the machine with issues, I can download from the internet and from other local machines at full 100mbps, and I can upload TO the nas at the same speed, I simply cannot download from the nas at anything near full speed.
What can I check that could be affecting just downloads from the one nas device to this one machine and nothing else? All other transfers are at full speed?
Edit just to add a little network info. Router is a Netgear R7000. Nas connected to R7000 gigabit port. PC connected to 500mbps TP Link powerline plug (synced at ~350mb, has 100mb ethernet ports). As mentioned above I can achieve full 100mbps speed downloading from the internet or from another local machine on this network, and can upload to nas at that speed. Just not download from it, which goes at 3 - 4 MBps.
Jumbo frames not enabled, MTU is 1500. I will try a direct connection from NAS to pc later but anything I can try in the mean time appreciated.

-----------------------------Hi randomnut1,
Thanks for doing such tests that may help us fully isolate this issue. If it's okay, can you share a folder (with some files) from one of your PCs to your network and test the Read/Write speed in accessing the files using this Windows 10 PC.
Kind regards,
BrianL
