Win7 slow network file transfer

The reason was because of packet signing for SMB traffic. It seems when you enable packet signing it significantly reduces the file sharing speed. If you really want to drill down, then you need to give more details in comparison to the machines running the 2 OSes :. If you're running broadcom nics, try disabling VMQ on the physical nic you're using. You mention you're using the manufacturer drivers, are they the latest build?

I do not have any virtual switch attached to a physical network adapter. So nothing to do with VMQ I assume. To continue this discussion, please ask a new question.

You can have a look to microsoft reference as well. Good luck. The NAS box must be working ok as the wife and I can both be watching different shows from it at the same time with no issues we have 2 network media players. I'm using the standard built in Windows Firewall. Is there something there that can be set to say anything in an IP range of This is very frustrating.

As mentioned in my post, sometimes the high transfer speed will come back of it's own accord, either after restarting or even being left alone without a restart, but I've now got TV shows from the 15th Feb that I still haven't been able to transfer given the fact I try at least once or twice a day and it still wouldn't transfer up to the 21st Feb.

So I then grabbed the 10 or so other TV shows that I haven't been able to transfer since the 15th Feb and dragged them to the mapped drive and within a couple of hours, they had all transferred.

Mind you, this is how it goes. That's why I suspect it might be some service that needs to be running for good network transfer speeds or perhaps not running, if the service is putting too much overhead on the system. That's why I'm hoping there's some logging that I can examine and compare a good transfer speed to when I have lousy speed.

I have the same question 7. Report abuse. Details required :. Cancel Submit. Debleena S. Step 2 Also disable the flow control of the network adapter by following these steps: 1. Hope the information helps. Please post back and let us know. How satisfied are you with this reply? Thanks for your feedback, it helps us improve the site. In reply to Debleena S's post on February 27, Because I've had random times after a re-boot where transfer speed has been good, I won't be convinced until I've checked it over a few days.

If I try to transfere a file either copy and paste into a shared folder or ftp from one pc to the other I get Kbps not eve Mbps. Why is this both running windows I tried all of the ideas on this website and nothing fixed it. I started thinkig either Bit-Defender or something?

I had the same issue and I wasn't able to get anything faster than 1. After reading other posts and seeing the 1. And it's the limitation of the chipset itself Broadcom has the same issue with their IC's. Now, i'm pretty much limited by the throughput of the Drive. No matter if the drive is connected directly or I'm copying to it over the network, the speed is the same.

Good luck everyone. Please let everyone know if that worked for you. Thank you. I remembered that the 5ghz radio was disabled and paused the transfer I don't like the high speed radio, so I disabled it and then it turned out to be something I kinda regretted Mate, it worked like a charm for me also without a restart so thank you very much.

Just makes me wonder why this setting has caused me this problem when it never has before? Oh well, it's working now and I don't have time to ponder that. Do you have any other idea? I have 2 pc with win 7 home.

Try booting from "Safe Mode with Networking" to see if some third party software is not the cause of the problem. But it is set to 'disabled' already. What else could be the problem here? We have a mix of xp and 7, with our server being SP2. Iam also facing similar issues , between 8. Thank you! Your last suggestion worked in the midst of a Windows Easy Transfer. Network utilization was less than 1percent on two Windows 7 bit machines.

After, it jumped past 60 percent and stayed there on both machines. Thank you so much for sharing this info. I have been battling this for along time. Thank You Thank You. You just made my day! Thanks so much. I still do not know what caused the problem but it appeared immediately after installing a new Internet Security Software on all Workstations. Thank you again. This worked wonders. It at first said 19 hours, but after this fix it's down to 8 hours.

I still think that's too slow, but it dropped to half so thanks for that. I just sent 35 in 10 minutes from my laptop to my PC I did the settings on both, pc and laptop Wait, your comment is from 5 years ago..

Had the same problem. My network server is XP machine. My new used laptop is Win7. The "Jumbo Packet" setting did not solve the problem. It had been set on "Force " My speed went from about kB to 10Mbyte.

So wrong on so many levels.. Your not getting MB, changing the duplex to full negotiation would only help if you have a high speed than MB 1, Off the hook! Thanks a million! It must have taken you hours and hours and hours to find a solution.

First i realy want to thank you for this. Man I have had this issue for a long time. I thought that I have tried everything to pickup my LAN file transfer speed and nothing worked.

Till now. Even large files transfer in seconds. Thank you very much for sharing this info. I'm sorry, I've tried all the solutions, unfortunately, my problem continues.. I have 3 PCs. PC1 is our server PC with a practice management program. I have mapped the drivers of the 2 workstation PCs to the server PC for full access of the program read and write. I have turned off LSO and network speed has improved but only when one workstation is on at a time, when both workstations are on, network speed is slow.

Does anyone know what else could be the issue? Have I mapped the drivers wrong? Do I need to reset my modem? Wow, changed settings in the middle of a copying files. Estimated time started at over a day and dropped to mater of about 20 minutes.

Worked great make sure not to forget the reboot. Tried looking for this option on my windows 8 machine, and don't see the options listed under the advanced tab when I double click on my network adapter, could it be stashed somewhere else? Called something else? Any ideas? Thank you sooooo much. Now I just need that fast speed out of my wifi. Is there a trick to that too? It worked for me although in my case the v2 options were already set to disabled and the non-v2 option "large send offload IPv4 " was enabled.

I don't see Large Send Offload. HELP my speed is only a few kbps. I have something different - "Task Offload" in my Atheros L1 Gigabit card, Should this be done on both computers or just the sending one? Assumed both. Thank you so very much.

Its working as if my network is on Steroids. I have a NAS connected to my network and only the top folder would connect and the rest of the folders would take up to 15 seconds to give me the log-in window, now, it doesn't even take a second. I appreciate you writing this up! It appears to be the answer to my problems as well. The only question is, I have workstation Is there any way for a Group Policy to be made for this so that I don't have to visit workstations?

The Offload setting fixed my Windows copy speed! Funny though, if you use a different copy manager like TeraCopy, speed was pretty good. This worked "like a charm Quote from "Santoxthanksyou" above "! Thank you I followed your steps exactly for both computers the third suggestion, the one that worked, the "LOS" option -- didn't even have to re-boot but will do it anyway before this put the transfer speed "on Steroids Quote from "Brian" above.

Thanks for posting this. I had to both disable LSO and enable jumbo frames to get the performance improvement, but importing a CD now only takes a couple of minutes. I get to step 5 and instead there is no list of options under the advanced tab Just a button "nvidia Ethernet configuration" which when I open it lists some options but not the LSO option I can't seem to fix my problem.

I tried all 3 options but the speed just around k. I tried to get into the network adapter setting and find the "Link Speed" is set to "mb Full Duplex", so I set to "1. Some time ago I experienced a slow connection when transferring large files.

After I disabled large send offload on my networkcard killer e gigabit ethernet controller ndis 6. Since yesterday I have a slow connection again. I didn't install something new and LSO is still disabled. Any ideas how I can fix this? Thanks in advance,. Thank you for the info. I really helped was struggling with slow lan for 4 days nothing helped but these changes made wonders..

Can't believe this. Saved the day for me. Thanks a lot for sharing the solution. I was transferring data over LAN between 2 laptops one of which is Windows 7 and another is Windows 8. I tried ll your suggestions to increase speed. I just wanted to chime in and express my gratitude for this solution.

Ah finally i found a solution! Starts of at or so. I tried these without much luck. Turned on autonegotiation and bingo. I think I might owe you something huge for this, but have nothing to offer. This brings about the end of a very long-term frustration. Many thanks for this post. You deserve an award or something. Thank you very much. It was one older computer on our network that was slowing down other resources.

After disabling LSO on that station it has helped all around. I did the opposite. I enabled Jumbo Packets, the largest size. That fixed the problem. However, my case is special. I am downloading over a university campus LAN. If you have that service running, check this article on how to remove it.

Thank you, thank you and thank you. Any ideas how to fix slow speed transfer over VPN? I know to some degree the speed is reliant on the VPN provider. Waiting anywhere between 12hours and 18 hours is way to slow for a 20gig file. I am getting speeds of kb or less. Very slow. Check this article. It has quite a few suggestions on how to fix slow VPN speed.

For years I struggled with slow speeds thinking that it supposed to be like that. Thank's heaps. It might help you steer into right direction. For example, the answer has the following information about "Jumbo Frame" :. If users enable both of them, the driver automatically chooses Jumbo Packet.

Now both directions work. What a stupid feature.
