X220 wifi slow problem

I just bought a x220 4286CTO , it is a good machine but the wifi connection is really annonying .

It becomes  very slow after 10 seconds or so after I turn on the wifi connection even the link status shows "300Mbps". 

The chip set is "intel wifi link 1000" in windows 7 64bit. 

I do see packet drops in ping command to web sites such as "".

I have upgraded to latest version of driver, v14.1.1.3 , but still no luck. I am using WPA2  PSK plus AES, other devices (iphone, ipad, T400 and etc) work well in my house.

Any idea ?

Re: X220 wifi slow problem

hey atlantisnj,

uninstall the Access Connection. Try connecting using Windows built-in connection system. Does it work and are you able to maintain a good speed?

If it does not, try uninstalling the current wifi driver that you have installed. let windows install its generic drivers and try again.
