How come when I connected my new computer to my network everything seemed to get really slow?

by on August 3, 2011

Q: i just got a new computer, there are 2 other computers on my home network, as well as 2 ipod touch devices. one computer is receiving wifi as are the ipods, and the 2 desktops are connected directly to the router…everything was peachy until this new computer ( a replacement for a fried one) now whenever i download anything of significant size (but as seemingly insignificant as 40MB) that download will slooooooow down ,and pages or apps will load on the houses other comps (or this comp) or this computer bogs the heck out of everything or blocks stuff, or..i dont even know..but its horribly annoying. and this computer, supposedly – performance wise is an UPGRADE from my i really dont get it.

    First thing, try a different Ethernet cable with the computer to see if it makes a difference.


      mmm k..replaced it.. no obvious change. :o(


    The usual problem here is that the computer is having a hard time either sending or receiving data packets so it keeps retrying to send/receive the same data. The trick is figuring out what part or software is causing the problem.

    Next steps:
    1. Go to the Dell website and make sure you update all drivers for this troublesome computer.
    2. Go to the website for the router manufacturer, grab the latest firmware updates for that too.

    Try running & on the troublesome computer and one of the ones that works fine normally and note any big differences.

    Also consider trying a different Ethernet card in the PC if you have one handy, try a different port on the router, try hooking the cranky PC directly to your cable modem.

    I’m assuming you’ve run a full anti-virus/anti-spyware scan on the pc too right?
