Download speed very slow on the wired Ethernet connection

I am currently getting 200 Mbps down and 0.3 MB/s on my desk wired Ethernet connection. I should get 200 down and 20 upwards.

  • On my wireless adapter on the same router, I have ~ 18 Mbit/s to the top and about 15 Mbit/s down, which seems that the wireless adapter works fine.
  • I plugged in another computer with the same cable on the same router port and got the full speed (200/20), then the problem lies within my computer.
  • I made a transfer of files to and from my computer to another computer connected to the same router and I got the full speed Gigabit times come and go.

I searched high and wide on the internet and forums, and that many people have had the same problem I have, nothing of the multitude of solutions worked for me.

That's what I tried without success:

  • Uninstalled the Ethernet card, deleted the drivers, forcing the new drivers to install again. No change of speed.
  • Carefully checked for Virus and malware programs (crossed the registry as well), but found nothing, and nothing has been installed recently other than windows updates.
  • The only antivirus I have is Windows Defender. I turned off and turned off the Windows Firewall, but speed did not improve.
  • I tried with IE, Chrome and Firefox, speed with different services and all tests show similar speeds. I also used FTP to a server I have, and the speeds were the same.
  • There is no other traffic devours bandwidth.

So what I have gathered so far, it's that my Ethernet card works very slow only when downloading from the internet. Within my network, it works fine.

What is a service that does not work well? If so who? I am not knowledgeable on the use of all services. I checked IPv4 and IPv6 and they both seem to be configured correctly, but I can't say that I am certain of what "correctly configured" is.

These are my specs:

HP Desktop H9 - 1215t

Windows 7 Ultimate SP1

32 GB OF RAM

64 bit

Chip Intel i7-3770

Controller Atheros AR8161/8165 PCI - E Gigabit Ethernet (NDIS 6.20)

I would really appreciate some help here because this problem I'm paralyzed.

Thank you for your time,

Tom

By George, you got it!

For someone who thinks he's good at Googling, I could sure use some improvements!

The key has been the link to explanation. While I had been close to my tests, this for shows that even when you sort-of-one little-peut-be-think you know what you're doing to keep your legs unless you know EXACTLY what you are doing.

The answer was definitely Large Send Offload, but it was a little more complicated, at least to understand what really happened. Neutralization of him gave the tour, but now I work with an active v2 and it works like a charm.

I will detail what, in my opinion, happened here for those who may have similar problems so that they (you) may be able to figure out, as all cards are different and may require slightly different settings.

I live in an area where so far the download speed over fast, I was able to get is 2 Mbps, on a good day, it's usually on average 1 ~ 1.5 Mbps. download speed is between 5 ~ 20 Mbit/s.

I do a lot of video work and I constantly have to download large files on my servers. I got the computer described above about 8 months ago, and my Age (2 years) one remained on my home network.

For a week or two, I was cursing my ISP because the internet was slower than usual and very glitch. I tested my speed and got 20 down and 0.2, repeatedly. So I went through the long and technology-challenged call representative to 'help' me, I was paying for 20/2. Only option was to wait a week for a technician to come out of my house, he stressed have shot my injurybut not before you ask me, that there are faster speeds to internet available in my place. 200/20 which is 10 times what I had, so of course I went with her. In doing so the representative asked me to Exchange my modem/router for a new handle faster speeds.

When I replaced the modem/router, I found that the download speed went from 50/0.2 (after the new request speed but still with the old router) to 200/0.3~0.5 with the new router. I also had a Cisco E2000 router that I turned into a switch, which was also bogged down internet high speed (now that they have been much faster). But still the download speed has not really improved.

This long and winding history is so that you (read this with a similar problem) might find the answer to your particular problem.

Looking back when I said that the issue was in my computer because that became high speed was not quite accurate. The 'problem' was beyond my router, if the solution was in my settings with the LSO parameter. The 'problem' was not really a problem since what I see (guess) that's happened is that my ISP has been updated with equipment, and the settings on my new pc has become a problem while paradoxically not so in my old pc.

My old pc equipped with a "Realtek PCIe GBE Family Controller" and the IPv4 LSO parameter turned on, that she was no problem under the new set of circumstances ISP. 200 / 20 Mbit/s.

Then when I compared the setting on my new computer, it never crossed my mind that the neutralization of him would solve the problem.

My new pc has a Atheros AR8161/8165 controller PCI-E Gigabit Ethernet (NDIS 6.20). This adapter has a setting "IPv4 LSO" more setting "IPv4 LSO v2" and "IPv6 LSO v2" décor. I don't think that my ISP uses IPv6.

In my quest to solve the problem, I placed all of the above settings to "Enabled", without success and in my fog don't reverse these settings.

With the 3 off, it worked fine, but I got a 5 ~ 10% improvement on the download speed with the LSO IPv4 v2 enabled and the other disabled.

There is no way representing the service provider on the phone could know this, so calling them would not / has not solved the problem. Even waiting a week for the technician most likely would not have solved the problem as it would be measured using a laptop full download and the download speeds.

I'm sure this will become a problem most current internet speeds that House are starting to soar (thanks Google!), so I hope this helps those who have similar problems.

To summarize:

Click on start->Control Panel->Device Manager->network adapters-> your adapter name (mine is Atheros AR8152/8158 PCI - E Fast Ethernet Controller (NDIS 6.20), right click and select Properties. On the advance tab, find good Large Send Offload (IPv4) and change its value to disabled , and then click on OK.

If you have a Large Send Offload (IPv4) v2 try to set that to enable (with either a handicapped of course).

I hope this helps!

And thank you George.

    PROBLEM * PROBABLY * SOLVED!

    Well, I tried something I should have done immediately: download the latest driver wireless.

    After you have installed the latest driver for my G62-340US laptop wireless, I'm finally reaching internet download speeds similar to my office (which is connected directly to the router).

    I will edit this post once I have do some testing LAN speed, but it looks very promising so far...

    EDIT:

    Yep, LAN speeds are where they should be with my current wireless router.

    Anyone else having a problem with slow download speeds should update their driver.

  • Download speed very slow wireless on Qosmio x 500-10T

    Hi all

    Just upgraded to a Tosh Satelite to a Qosmio X 500-10T - thought this would solve problems of speed, I got with the old machine using XP and a Belkin (g) wireless network adapter for the (n) on the Qosmio. Everything worked OK with the old Tosh but the new Qosmio is a disaster.

    I went through all installation steps, read all the forums, the updated drivers, but still, I get 50-80 Kbps when using the wireless. When I connect using cable, I can get all that Virgin can send me (app 2 MB, up to what I've upgraded, [when I can get 2 MB])!

    I tried the setting on my router (linksys WRT300N), it was capable of serving a Vista PC (wired) and two laptops, a Vista the other my XP, two laptops on wireless.

    I was wondering if Windows 7 has nothing to do with the problem but I don't see what parameters can be wrong or is it just not compatible with my router. Someone has an idea of the required parameters, or is there a digitization program I can run that will tell me? (I don't want to have to drag a cable around the House!

    Hi Gallan,

    If your WLAN speed is slow, you should try the following instructions but first of all make sure that your WLAN driver is up to date and it can be downloaded directly from Toshiba:

    -Updated the BIOS to the latest version
    -Disable management feature in Windows to energy WLAN power management
    -Put the router and the laptop N project only
    -Try with other encryption, e. g. WPA2
    -Update the firmware on your router
    -Disable the MAC address filtering and other security features

    I hope that helps!

  • New installation of Windows 7 translates speeds very slow of the internet. Works in safe mode.

    3 weeks ago, I installed windows 7.

    For some reason, internet is super slow. I noticed right away because the download of the updates took forever. I thought it was because I need to install the NIC drivers, so I only have the first. It didn't fix it. Then, I searched and tried everything I could find online. The only thing that did work was that if I boot mode safe mode with network speed is very well .

    When I discovered that, in safe mode, everything was fine, that I started to disable any service that relates to networking. (As the Base and support Ip filtering engine, etc) This does not solve it so I decided to try the oppisite I started in safe mode with network and then loaded to the top of msconfig and any service that was not running in safe mode, I turned off. Thinking that I start one by one and find out what service was slowing downloads. When I booted in normal mode, the download speeds were still broken.

    So I continued then to disable services, I disabled all services which have to do with networking, and to enable windows.  (Things like the service that launches programs. Yes, any program that has not been opened I could not open.) Accordingly, I have concluded that it was not all services.

    This is a new installation, so I only installed firefox and flash. (no flash for the speed test) no anti-virus, etc.

    Here are a few screens of speed trials. These are actually kind of funny because the download is so fast that downloads.

    It is in safe mode with network speed. http://imgur.com/7VJvt

    It's the speedtest in normal mode, http://imgur.com/dDp5B

    So here's what I tried.

    • disabled auto-tuning
    • disabled IPv6
    • turned off homegroup
    • reinstalled drivers
    • drivers uninstalled (for default windows drivers)
    • Install different drivers (installed a game on the asus site) and the other on the nvidia site
    • disabled many services to many-on-list really out.
    • disabled Windows defender and windows firewall.
    • I bought new RAM with the win7 update so I tested to see if the RAM was bad. I ran Memtest86 + and it failed. So I took the new RAM and he run and all past. Still doesn't solve it.
    • I reinstalled.
    • I installed another network card.
    • I installed another version of Win 7. (Installed Win7 professional first and after Win7 Ultimate)
    • reinstalled the drivers again.
    • Disable all of the services.
    • A run anti-virus programs. To make sure that there are no viruses. There are not.
    • I connected directly to my router.
    • All the latest windows updates installed.
    • Checked online to see if my hardware is compatible with Win7 http://www.microsoft.com/windows/compatibility/windows-7/en-us/Details.aspx?type=Hardware&p=ASUS%20P5N-D%20ATX%20-%20nForce%20750i%20SLI%20Motherboard&v=ASUS&uid=P5N-D%20BULK&l=en-US&pf=0&pi=0&s=P5N-D&os=64-bit

    FIXED!

    So I gave up and gave my computer to my friend at home and take a look. He brought me.

    What did do? He went out and bought a new network card. I guess that despite the windows NETWORK card drivers 7 I installed windows for some reason any dislikes the network card. (NVidia nForce 10/100/1000 Mbit / s) It is built in the nice for the card mother P5N - D.

    The funny thing is that 3 1/2 weeks, when I had the problem. I asked him what he thought and he said to go out and buy a new network card. When I hesitated to do so, he said he would buy the NIC if it did not work.

    In any case, I hope this helps someone maybe who has the same problem, I did.

  • Download speed very slow on connection ca 5 GHz

    Hi all!

    I recently Airport Extreme with 802.11 ac.

    My ISP gives me 100/100 Mbit ethernet cable access.

    When it is connected through Ethernet, the speed is ok.

    When I go wireless on my MacMini using the download speed for the network 5 GHz is 100 Mbps, but upload is of 30-35 Mbps max.

    All,

    I have this SAME problem.  I just bought my m6 Pavilion three days previously and immediately noticed that the download speed is very slow.  In addition, a lot of things people recommend this site do take into account that the laptops are brand new, the parameters are already factory installation and things are not running in the background whenever we try to download.  And just like the original - poster I have my old laptop awkward, almost dead here and it's the things download 5 times faster than my new laptop.

    Also, I found another post online from a user in HP Pavilion, who bought a new laptop and this is the slow download.

    So taking all this into account, a PERSON LOGIC CAN CONSLUDE THAT THE PROBLEM IS WITH the computer PORTABLE PAVILION.  Yes, is there an employee HP mans this site who can lift this problem and come back with the official HP answer to why this problem occurs?  I will definiately go online and noted the low ratings sites flag if I don't get an adequate response.

    Myron

    If you take the time to register to your original with Adobe installation (which most people do not), you can log in to your Adobe account and get the serial number. If you use a Windows computer and still have access to the old computer where Lightroom is installed, you can do the following:

    1. in the window folder options, make sure that you are able to see hidden folders.

    2. go to the C:\ProgramData\Adobe\Lightroom folder.

    3. use Notepad to open the file, Lightroom 5.0 Registration.lrreg

    You will be able to retrieve your serial number of this file.
