Very Slow Network Transfers

[turquato]

Hi

 

I have a brand new TP-Link TL-SG1016DE 16-port Smart Switch (10/100/1000) which I connected to an old Cisco Linksys E1200 N300 (10/100) Router I had lying around.

 

I hooked the switch to the router using CAT6 cables, made sure my computers were in the same work group and tried to copy files from one another.

I am well aware that the router I am using will limit my transfer speed to 10/100 and that's fine.
My problem is this, I tried to transfer a 2.9GB file and the transfer speed is very very very......painfully slow.

 

How slow you might ask? Well I was staring at a 355kb/s with an estimated 3hours+ and counting.

I've also observed that while copying files, the transfer speed gets stuck at about 155kb/s and sometime at 355kb/s at random

 

I have a windows 10 PC which I am pulling files from and a windows 7 PC to which I am transferring the files to and vice versa.
 

What could've gone wrong? What have I missed?

Can someone please shed some light.

Getting limited from the router. 100Mbps isn't fast. You're likely getting bottlenecked by the hardware of one of the PCs. Are you using your Windows 10 PC while copying files?

Can you elaborate a little more?

 

Is one PC connected to the switch (physically) and the other to the router over WiFi?

Are you transferring many smaller files or one large file?

yes, I am using windows 10 on 1 PC and a windows 7 on another. both are connected to the network via the switch

Both of the PCs are connected physically via the switch using CAT6 cables. I am transferring a folder with multiple files (some large and some rather small in sizes) with the accumulated size of 2.9GB

ah thats a big info right there, i though you transfer ONE file 2.9GB so i had no it would be so slow.

 

it looks like you are limited to 10mbit right now for whatever reason and that would mean max 1.25mb/s with the overhead of trying to transfer multiple small files it could be normal to have that speeds.

 

if your computer detecting 100mbit or 10 mbit on the network interface?

my Switch detects 1000mbit link for both win10 and win7.

Can you test another switch?

Zip the file and transfer it that wat?

Test it in safe mode with networking?

that should not be happening, if you go through the 100mbit router one side should not be detecting gigabit speeds.

No I don't have another switch to test.
I am now transferring a zipped file but I'm stuck on 355kb/s, nothing seems to be moving.
Will try to test with safe mode

Edit: about 5minutes past and it only moved about 2% of the file size

well...my computers support gigabit connections. both are connected to a gigabit switch so both should register on the TP-Link Switch as gigabit compatible and the gigabit indicator LED lights up.

The ones connected to my router are the modem and switch.

Can you show us what your PC shows about the connection? I'll leave an example of my 1Gbps connection.

Can you also show us a schematic of your layout?

ah that makes more sense so both are directly connected to the gigabit switch and you transfer directly from one PC to the other correct?

 

do you use SMB to transfer this files?

I can confirm that I too have the same Speed 1.0Gbps both on my Windows 10 (PC 1) and Windows 7 (PC 2). I'm currently at work so I can't post the same image.

 

But anyways, here's my home network diagram

Yes, I am transferring a file from a Windows 10 PC to a Windows 7 PC.

 

SMB you mean Server Message Block? I'm not sure if it is being used. I just did the file sharing function of windows. But if that is SMB, then I am using it.

My computers are on the same work group. Folders have already been shared and are visible to one another while using the Network View. I can copy the files to and from. The only problem is, the file transfer is very slow

Try to test your actual speed with iPerf (JPerf for a GUI). If that is fast, the problem is Windows file sharing and not your network.

I was just about to try the iPerf and the problem went away. I was prompted by windows update to restart my computer to install updates.

 

After that everything worked.

I'd like to thank you all for your time and effort. Will take note of your advise for future references.

 

Apparently a windows update just fixed my problem.

It could have been Windows Update limiting the speed while downloading, not seen it myself but have heard it can do that.

How many files?  Is it SSD or HDD?  A slew of smaller files will transfer around that rate, validate by transferring one large file and observe the difference.

I never thought of that until windows prompted me with a restart to update some components. It could've been that or it could've been the Killer e2500 network drivers.

It was a lot of files, contained in a folder, with very small to large files (15kb - 400MB+)
I've tried transferring both just the folder & sub-folders and a zipped file & a single .iso file but the problem still persisted.

After a prompted reboot from windows, everything went smoothly. transfer speeds are normal but still limited by my old 54Mbps router. It's no that big of a deal though 54Mbps is plenty for my needs but will upgrade later when I see gigabit routers that are cheap (brand new or used)
