Thinkpad X121e upload speed issues Ethernet Connection

I am not at all IT minded but ever since I received my Thinkpad it has always had a dire upload connection speed which is causing me a big headache.

 

I work in a serviced office and my download speed using speedtest.net is 30.77mbps and my upload is 0.77mbps.

 

If I go onto my wifi network I just got 32.25mbps download and 10.05 mbps upload.

 

The problem is that I need the wired connection for my copier to be able to talk to my laptop.

 

Lenovo have just left after fitting a new motherboard and they suggest its a software problem...I am using Windows 7 Prof.

 

Any advice would be gratefully welcomed !

Hi Dan41275,

 

 After reading a bit about the issue your having it would see your not alone in having upload speed issues windows 7 prof. I was hoping if your ok with it could you give me a little bit more info about type of router your using and the type of network card you have.

 

Alot of the post I read on the issue have started by going to device manager and updating your network driver. Heres the link http://www.techsupportforum.com/forums/f31/super-slow-upload-speed-616997.html

 

I hope this helps you!

Dan,

 

I think you are telling us that you are getting better performance via wifi than your wired ethernet?   If so, then I think Hiro's suggestion is a good first step to ensure your ethernet drivers are at the latest level.

 

If possible, try to move the ThinkPad to another location in your office and try a different Ethernet port and cable.  It is possible that either the patch cable at your desk is damaged or the internal wiring from that port to the router, or the port on the router.   You might also plug another PC in at your desk and run speed test to see if you are getting different results.

 

Please let us know the results of your futher tests so the community can continue to help.

 

Best regards,

 

Mark

Hi,

 

The network adapter is an Atheros AR8151 PCI-E Gigabit Ethernet Controller (NDIS 6.20)

 

I know the driver is the latest and hasnt changed anything,

 

Regards,

 

Daniel

Thanks for your post.

 

The Thinkpad remains exactly the same regardless of where it is plugged in either at home or work. Plugging in my old laptop gets upload speeds of 7mbps in the same port.

Re: Thinkpad X121e upload speed issues Ethernet Connection

Hey dan41275,

 

Thanks for sending me your network card specs and for trying another computer to help us troubleshoot your issue. The suggestions from Mark_Lenovo were great and I hope you found them helpful. From what I can tell you have said your drivers are updated and that when you try another computer with the same ethernet cord which is connected to same router, your upload speeds are higher.

 

I would suggest running any anti-virus software you have and double check your firewall settings on your computer to make sure everything is clean and all the correct ports are open.

 

On a side note can you run trace progroms? If you have admin rights try running this ( copy paste this into your command prompt window and when notepad pops up paste the results.

    

tracert google.com>c:\tracert.txt&notepad c:\tracert.txt&exit 

 

Thank you again,

 

Hiro

Re: Thinkpad X121e upload speed issues Ethernet Connection

Hello,

 

Perhaps there is a problem with network speed and duplex detection?  See if you can find out what speed the Ethernet port at your desk is provisioned for (10, 100, 1000Mbps, full or half duplex) and manually set the network connection on the X121e to the same settings.  Let us know what difference, if any, that makes.

 

Regards,

Hi dan41275, Yes the command given by Hiro creates a text file. If you haven't created the file before, you need to let it create a new one.

I don't work for Lenovo. I'm a crazy volunteer!
