[Solved] Two laptops - one download 20Mb/s - the other only 8Mb/s

Hi all,
Just puzzled that one laptop with Windows 7 can download the max 20Mb/s no problem via ethernet and the other, Arch Linux only getting average 7 - 8Mb/s.
Both laptops similar specs and are there settings that I'm not aware of to improve network speed?

MrRoberts,
Consider the question as you posed it to us, and look at it from your reader's point of view.  What have you given us into which we can sink our teeth?  Without specifics, we will soon be arguing how many Angels can dance on the head of a pin.
For example,
Are you talking about a Wireless network, or a Wired network?
What are the chip sets used by the NICs?
Are they communicating through the same router?
100 Base T?  10 Base T?  1000 Base T?
802.11g ?  802.11n ?
Open, WEP, WPA1? WPA2?
TKIP? AES?
What are the make and model of the router?
Are both cards configured to use IPv4?  IPv6?
Is there any chance the two systems are presenting the metrics differently? MB/s vs Mb/s ?
Are the machines trying to download from the same site with different results? Or from different sites?
Same time of Day?
How fast do you think your internet connection should be?
What are the data rates when talking to other computers on the LAN? 
Are they configured to use the same DNS server?
Are there any "Interesting" messages in the logs?
Have you looked at any of the diagnostic information that details lost packets. retries, etc?

  • HT1386 How do I switch users on wifi sync for example my Mac has two users one apples MacBook pro the other is my name I want to switch from apples MacBook pro to my name how is this done?

    How do I switch users on wifi sync for example my Mac has two users one apples MacBook pro the other is my name I want to switch from apples MacBook pro to my name how is this done?

    Try connecting the iPad to the computer that you do not want to WiFi sync with and uncheck the WiFi sync option in iTunes. Then click on Apply. Reboot the iPad and see if that does the trick.
    Reboot the iPad by holding down on the sleep and home buttons at the same time for about 10-15 seconds until the Apple Logo appears - ignore the red slider - let go of the buttons.

  • Two laptops - one will connect to the internet and the other one will not

    I have two home laptops.  Both show as connected to my network with full signal.  However, when you attempt to open the internet, one laptop will not open and the other one will.  I have tried connecting with just the cord from the router to the laptop and it doesn't work; I have tried looking up the IP address and one laptop address is different from the other - I don't know if this should be this way or not; I have tried doing the start, run, cmd, ipconfig, and I got 4 replies, but when I typed in ping space yahoo.com, I did not get the replies on the computer that will not go on the internet, but did get the replies on the other laptop.  I don't know what else to do - please give me some ideas.

    Make sure the IP address is set to DHCP, and browser is not configured for any proxy server.

  • Hi I am hoping to add my 2 TB time capsule to my existing wireless network using cisco dpq 3925 modem. I have two mbp one running Yosemite and the other os 10.7.5

    I have a time capsule 2TB model 1409. I would like to connect it to my existing wireless network (using a cisco DPQ 3925 modem). I have two mac book pro one running Yosemite and the other OS 10.7.5. The best I can do is to connect the TC to the Modem via ethernet. Have one of my MBP connect to the time capsule using a ethernet cable and have the TB set to bridge mode. In this configuration, both mbp and the iPad can detect the TC but when I try to connect it to the wireless network, using the same network name and password, the light flashes amber and I cannot detect the time capsule again.

    Correct..
    The best I can do is to connect the TC to the Modem via ethernet.
    The TC does not connect to non-apple routers by wireless.. well. It is possible but so poor a method that Apple seem to have eliminated it in the setup wizard.. I would take that as a good thing..
    If you cannot use ethernet you have two choices..
    Use another apple router that is plugged into the Cable modem.. eg a second hand Extreme Gen5 or the latest Express.. the Extreme is both cheaper and better.
    Or you can use a set of EOP (homeplug) adapters.. but they cannot be guaranteed to work so you should buy from a place that allows returns.

  • Can you link two iPhones, one on pay monthly the other on pay as you go, to the same iTunes account? As once sync'd the pay as you go looses its service provider??

    Can you link two iphones to iTunes account, one is pay as you go the other is pay monthly on different service providers, the pay as you go when sync'd can't find it's service provider ??

    The iTunes account has nothing to do with the cellular service provider. So you should be able to have both phones on the same account. What problem do you have with it?

  • Trying to connect two WRT54GS one has gateway and the other as router... HELP!

    Long story short i have 2 WRE54G v2 and still dont get the signal i want. My last ditch effort is picking up a WRT54GS v6 last friday with high gain dB antena to act as an extender. My current WRT54GS is v1 with high gain dB antena. Can i get these routers to talk to one another wirelessly?
    Help!!!
    Idleloud

    Mort is right.  They can not connect together with the linksys firmware.  Some third party firmware does allow that but third party firmware will void any warranty and you will not get any support from linksys.  I recommend adding a access point to increase the range from your WRT54GS.

  • I have two apple accounts on one computer. How do i delete one account without deleting the other?

    I have two questions!!   
    I need to know how to delete one account without deleting the other account on the computer?
    I am deleting the account because i have a new laptop that now has the my account... will deleting the account on one computer affect the account on the other laptop?

    What do you mean by deleting the account? One can't delete an Apple ID/iTunes account. One just stops using it.
    Since yo can only have five computer authorized for one iTunes account you might want to deauthorize the computer for that account

  • Two laptops - one mouse - one screen

    i have two laptops, one is a powerbook, g4, the another one a mac book pro. i need to know how can i connect both laptops to the point that it will view just one screen and use just one mouse.

    Take a look at buying a KVM switch. It's actually meant to control two computers with one set of keyboard monitor and mouse. However, this should allow you to connect your monitor to two computers. Look to buy one with a physical switch rather than a keyboard shortcut.

    You can use the same Apple ID for both phones, you would then be able to use the purchased Apps/Content on both phones without having to pay again.

  • Two Ni4472's in system, one swings to 10V, the other 6V, Bad Card?

    I have two NI 4472 Cards in my system, one swings 10V signal from a transducer in all channels, and the other only 6V, the problem follows the card.
    Do I have a bad Card or Am I missing something, I am using Lab View. Run-time 6.1, 7.0 and 7.1.
    Thanks for the help.

    Hi Rafael,
    The NI 4472 has an input signal range of +-10Vpk. If you have two NI 4472s in your system, and the same input connected to both, it is likely you have a malfunctioning DSA device. A good method to test the device is to open the Measurement and Automation Explorer (MAX) and reset the device, self-test the device, and verify a sine wave input is the same on both 4472s.
    Hope this helps,
