X220 wifi very poor performance

My new X220 comes with an Intel Wifi 1000 bgn. The wifi would only work if the computer sits few feet away from the router. It would not be able to connect to the wireless router if I'm sitting one floor above the router, while my other laptops do not have any connectivity trouble. 

 

When it connects, the speed could drop to very low even with "excellent" signal quality as reported by Windows. Any hints?

Re: X220 wifi very poor performance

Make sure your router has the latest firmware for it.  Seen this a lot with router with original firmware.  The router gets updated and most problems disappear.

Make sure the wifi adapter has the latest drivers too.

Re: X220 wifi very poor performance

Have you tried it on other access points to give you a hint of whether it's the wifi card or your access point?

Re: X220 wifi very poor performance

Hi

 

I have the same problem too. Extremely poor performance on my Link 1000 BGN wifi. Compared to my old Asus UL30 the connection range and speed is really bad. I have tested it with routers at two friends of mine too. Their laptops easily connects between rooms and across floors - my NEW X220 needs to be in the same room to get good connection. VERY disapointing!!!

Re: X220 wifi very poor performance

Could one of your antennae be loose?

Re: X220 wifi very poor performance

In Control Panel -> Hardware and Sound -> Power Options

 

Click on change plan settings for the profile you are using, then click change advance power settings -> wireless adapter settings -> power saving mode and make sure this is set to Maximum Performance.

Re: X220 wifi very poor performance

I have tried to play around with the wifi settings - does not help.

 

Have a look at this video: http://www.youtube.com/watch?v=7y0DdEXgHN4

 

I gues next step is to repair it?
