I've just changed ISP recently to 20/20 mbit and bought a Linksys WRT610N router to hook up my laptops wireless.

Everything is up and running now and I tested that the speed was as promised. Now, my first laptop runs smoothly, but my second laptop is dropping from 54mbps to 1mbps after about 5 - 10 minutes of regular surfing.

I've tried the following:

  • Change the channel (tried all of them) on the router
  • Cloning the MAC addresses on both laptops
  • DHCP reserved the IP addresses for both laptops
  • Changing security from WPA-2 to WPA
  • I'm not the most experienced when it comes to setting up network, so please bear with me ;)

    Any input on this problem will be greatly appreciated!

    Thanks in advance,



    It might be worth checking that you have the latest drivers for that laptop's wireless adaptor. It could be a bug in the firmware that causes it not to be able to retrain up to a higher speed after it has dipped down due to temporary interference, which updated drivers/firmware may resolve.
