Really slow transfer from Admin PC to Laptop

[bishop101]

I have 2 desktop computers and one laptop on a network, all three are also part of a Homegroup.

When I try to copy files from the main Admin PC to the laptop it slows down to less than 15KB/s. I thought perhaps it was the wifi reception but even when connected with Ethernet it's still terribly slow to the point that a 300MB folder takes 2 hours (estimated time). I end up cancelling the transfer sand sometimes windows explorer ends up crashing.

However when I copy files from the second desktop to laptop it is normal speed. No lag, no glitch.

All the files I tried to copy where share, available to Everyone. Everything else works fine, streaming video and music from the main admin PC is flawless, I just can't seem too transfer files from the main Admin PC to the laptop.

so you have 3 pc's (or even more)

admin pc->laptop:slow
second pc->laptop:fast

correct?

admin pc->second pc : fast or slow?

 

[Kaktussoft]

try to copy files:

admin pc->laptop: done from laptop
admin pc->laptop: done from admin pc

laptop->main pc: done from laptop
laptop->main pc: done from admin pc

Which are fast and which are slow?

For large files you are probably faster to copy to a stick or external disk and then from there to the other PC

yes, thats correct.

admin pc->second pc : fast or slow?

normal speed, but only if I'm on the admin PC. If I'm on the second PC trying to copy from the admin PC it doesn't work.

I should clarify that it's not going slow, it's stuck on Copying as if it's on queue, doing calculations and all that stuff. If I leave it for 10 min then it starts transferring files at around 7 kB/s, other times windows explorer just crashes.

admin pc->laptop: done from laptop
admin pc->laptop: done from admin pc

Does not work, stuck on copying as if it's on a queue, does not matter if I'm on the admin PC or laptop.

laptop->main pc: done from laptop
laptop->main pc: done from admin pc

Transfer only work if I'm on admin PC copying from laptop.
Does not work if I'm on laptop trying to copy to admin PC.

As for the laptop and second PC I can transfer files fast between both, it doesn't matter which computer I'm on.

For large files you are probably faster to copy to a stick or external disk and then from there to the other PC

500mb isn't large at all. I've been copying 20+ GB files from the second PC to the main admin PC frequently, takes about 15 min.

Could it have to do with Read and Write. I only have it on Read for the main PC because I don't want other users deleting folders.

 

[whs]

That is unlikely.

Try to do this:

copy a file from second pc to laptop. Once done from laptop, once donce from second pc.
copy a file from laptop to second pc. Once done from laptop, once donce from second pc.

Both actions mormal speed?

all average the same speed.

On admin pc in http://www.sevenforums.com/tutorials/783-elevated-command-prompt.html

netsh int tcp set heuristics disabled
netsh int tcp set global autotuninglevel=disabled

Reboot and try to copy again. To put settings back as they were:

netsh int tcp set heuristics enabled
netsh int tcp set global autotuninglevel=normal

perhaps i should get a new router.

 

[Kaktussoft]

on admin pc open "device manager". Now open "network adapters". Right click on your network adapter (not the wireless!) and click properties. Click on tab "Advanced". What is value of "Speed & Duplex"? What possible values do you have? Do it on admin pc and laptop.

It depends on the Network card (driver) how it's named. Maybe an extra tab called SPEED for example.

Does router support 1Gb/s, or is 100Mb/s the maximum speed?

So you did test laptop wireless and Admin PC wired?
Definitely a problem with Admin PC. Focus on Admin PC

Click on tab "Advanced". What is value of "Speed & Duplex"? What possible values do you have? Do it on admin pc and laptop.

Value = Auto Negotiation

Does router support 1Gb/s, or is 100Mb/s the maximum speed?

Data transfer rate is 54Mbps.

Not 54Mbps! that's wireless. I mean max speed of switch ports in router. Go again to "Speed & Duplex" setting. On admin pc set it's value to "100Mb Full duplex". Save it and reboot. Problem solved? If not... do the same on laptop and reboot laptop as well. If it doesn't solve the issue put the settings back to what they were
