X220 Antenna question

2011-08-06, 5:12 AM

I recently ordered an x220 i7 with HD Premium display (3x3) and the Intel 6300 Ultimate Wi-Fi card. My understanding is that there are 3 antennas in the screen bezel for wifi and another 2 for WWAN (I did not buy the WWAN card). 

 

I received my laptop a week ago and took the keyboard out to look at installing a msata drive and noticed the wifi card only has two antennas attached, Black and grey. It also has a red and blue antenna wires which are not plugged in (for the WWAN card).  According to the ThinkPad X220 and X220i Hardware Maintenance Manual there should also be a white antenna wire for the third wifi antenna. They call it the MIMO antenna.

 

I called Lenovo tech support and they told me to call sales because the system what not broken just built wrong. So I called sale and they told me to call tech support but they don’t have a clue what I was talking about.  

 

Has anyone run into this before?  Does anyone know the part number for the MIMO antenna? 

 

Lenovo wants me to send it in for repair but no one I have talked to has a clue what I’m asking so I’m not confident the repair depot will know anything about it either. Tech support can not even find the part number for the MIMO antenna.

 

I’ll probably just plug one of the free WWAN antennas in but I’m bothered I didn’t get what I paid for, or at least what they are advertising.

What does your system say is installed? Open the Device Manager (look in Network adapters) or Lenovo ThinkVantage Tools (open System Heath and Diagnostics, and look in System Information).

It says i have the Ultimate-N 6300 installed. I can also see 3 physical antenna ports on the wifi card but only 2 are connected.

I have the Ultimate-N 6300 (also a WWAN card) and mine has the white wire. It looks like your X220 was misconfigured.

Thanks for the pic RichardW That helps a lot. I dont have the white wire.

I also did not get the WWAN card but I see you did. i wonder if that has something to do with it. 

 

I found another thread on the same issue.

http://forums.lenovo.com/t5/X-Series-Tablet-ThinkPad-Laptops/X220-Tablet-Antenna-and-mSATA-SSD/td-p/473745

 

If i can get the part number for it I'll just order it. I would rather not send it back for repair. Maybe I'll just add a webcam. Looks like anothre call to support is in order.

The white antenna lead is the 802.11n MIMO antenna.  If you didn't order the PC originally with 802.11n, then I believe this white antenna lead is not present in the system.  I recently replaced my  Centrino 1000 with a Centrino Ultimate-N 6300 and I do not have the white antenna.  Yet, I wanted 5 GHz compatibility with normal Wi-Fi.  5 GHz works fine without this white lead.

While the card will function without the third antenna, it won't perform as it should.  Since you paid for a 6300 card, you should get the extra performance you paid for.

I would strongly suggest sending the system into service rather than doing yourself.  The cable routing is easy to get wrong and you have to disassemble the LCD. Also, unless you are a servicer, you are going to violate the warranty by trying this yourself.  You paid for the warranty as part of the system, so I suggest letting the warranty fix it.

Just tell tech support that your system should have come with three WLAN antennas and only has two and they will setup a service call and send you a box to ship the system into the depot for repair.
