The wireless card included on your system is average on it's best days. If you want it to connect to the latest N or AC protocol on 5GHz I suggest you upgrade the thing. 

 

I ordered the Intel 7260 to pair with my Asus router, but you might only eed an N card.

Hey Dan,

 

I will look into upgrading, is the intel 7260 good currently? as the prices dont look that bad. 

 

Another question, are you using the y400, if so was it pretty easy to remove the chip to replace?

I'm using the Intel Dual Band Wireless-N 7260, and I can get the internet speed on my university Wi-Fi, 300Mbps, 5 GHz connection.

hi jay_rab,

 

In addition to what cbautis2 have suggest, if you have the  Intel® Centrino® Wireless-N 2230, this device won't connect to a 5Ghz network as the card itself is only capable of 2.4Ghz. (see this product brief).

 

Also, upgrading the WLAN card is a good step to improve wifi speed but take note that some motherboard BIOS has a whitelist that restricts the usage of non-lenovo approved cards. Although there are modifications floating around to bypass this, in return, you may not be able to get warranty support if something goes wrong with the card.

 

 

Regards

You can find the whitelist for your Y400 on page 83 of 103 of the manual here: http://support.lenovo.com/en_FI/detail.page?DocID=UM016512

 

You'll see that the Intel Centrino Ultimate-N 6300 is on the approved list, but you have to buy the FRU version of that card.

From the Y400 manual, the FRU no. says 2002323, but note that that is not the actual FRU P/N stamped on the Wi-Fi adapter itself. The actual FRU P/N that is stamped on the Intel 6300 is 60Y3233.

 

This is true because when I looked at my Y470/Y570 manual, the FRU no. for Intel Centrino Wireless-N 1000 is

20002329. However, opening the bottom of my laptop and taking pictures of the Wi-Fi adapter clearly shows that the FRU no. stamped on the card is 60Y3241.see the image below: 

Capture.JPG

 

 

When you purchase the Intel Centrino Ultimate-N 6300, make sure on the pictures, there's the FRU P/N: 60Y3233 stamped on the Wi-Fi card.

 

 

Hope this helps.

All that's been said is good information. Switching the card is pretty straight forward.

However I must reiterate that the Intel AC card will only really excel if you pair it with an AC router.
