Why is my LAN so slow in transferring files?

[Police State]

I have 2 PC’s running Win 10 64 Pro, both linked directly into the back of a Draytek Vigor 2700 router using Cat 5 cable

I’m only seeing a network transfer rate of 11MB/s (via the file copy window) when I go to Task Manager of the send machine, it tells me it is sending at approx. 97MBps, and the receiving machine reports a receive rate of 99MB/s

Can someone shed some light on why I seem to have a low transfer rate somewhere between the two machines?

Slow RAM or slow HDD?

Your running as fast as you can at the moment.

11 MB/s is as fast as your router port is capable of :-

97MBps is roughly 11 MB/s.

Try running iperf3 between the two computers to verify the actual speed you are getting between them.

I using drives rated at SATA 6Gb/s

The Ram should be fast enough as its on a CAD workstation.

As above. The ports on that router are 10/100. If you want to go faster you can either upgrade to a router with gigabit (10/100/1000) ports or add a gigabit switch into your setup to speed up wired transfers.

Benefits of a switch is that it has more ports and will be cheaper.

Benefits of upgrading the router would, typically, be improved wireless performance and not having to add a second box.

Ok, maybe that will just confirm that I have a 'slow LAN' but whill it tell me why, or give me a clue as to why?

At the moment I'm copying 400Gb of data and the copy window is telling me 10 Hours!... it's been a long day, not sure i can cope with a long night too...

Also, if you are really running cat5 cable (rather than cat5e) then you need to upgrade that to cat5e or better when your get a new switch/router.

Thanks for confirming this for me. Can you recommend a decent router and/or switch. medium cost £

You'd be better off physically removing one of the HDDs and plugging it into the other PC, then copying the data...

I was actually just pondering that... I think i'll call it a day, and do that tomorrow.

Thanks for that advice, I'll get some Cat5e when i sort out a new router

If your happy with Draytek, this is a reasonable option.

£20 for an 8 port switch:

slightly less for a 5 port one from the same page. Plug your 2 PCs and one of the router ports in to that and you should see roughly a factor of 10 improvement.

Check all the cables you plan to use have all 8 wires present. 4 wire cables will only ever do 100 mbit or as the ~10MB/sec you have at present.

Guys, a humble and embarrassed apology, it's not a Draytek 2700,,, it's a WD MyNet750...
It's been a long day and my mind went down the wrong rabbit hole...


is The MyNet 750 just as limited as my old Draytek?

Dougie, please see my It's not a Draytek apology...

I don't have a brand preference... but I will need a router with at least 2 USB ports (for attached non-networkable printers)

You don't need to upgrade your router! Any cheap gigabit switch will do, I use TPlink ones they cost buttons.

https://www.amazon.co.uk/TP-Link-LS1005G-Wallmount...

Just plug everything into the switch.

Your internet will be <100Mbps so it's fine to use your existing router with its 10/100 port.

The PCs need to have gigabit ethernet ports as well as the switch.

Ok Ash, bear with me.

So i have a virgin router coming into the house.
I have a WD MyNet 750 connected to the Virgin router.
I have two pc's connected to the MyNet750
Everything else is wireless (TV/Tablets, etc) talking to the MyNet.

Do I plug the switch into the MyNet and then plug the two pc's into the Switch?


Also... how can i determine if my NC's are gigabit or not?

Google says that has gigabit ports, so your problem is elsewhere.

Cat5 cables...

We did the same, changed from 10/100 to 100/1000 (I think) and it was like.....a switch! Much faster.

And check your cables, as mentioned.

you mean, upgrade to Cat5e ?
