Trying to find the Broadcom 2x2 WLAN adapter for X120e

Not understanding the difference between the 1x1 and 2x2 designations of 802.11n, I ordered my X120e with the default 1x1 option. While the speed is OK when I'm close enough to my wireless router, the range is not nearly as good. (Not nearly as good as the 802.11g adapter in my T61.)

 

Now I know better, so I'm on a mission to buy the Broadcom card. According to the hardware maintenance manual, the FRU # is 60Y3251. If you Google this number, there's only one store selling the part: sparepartswarehouse.com. Has anyone ordered Lenovo parts from them before?

 

I understand from another thread on this forum that the BIOS has a whitelist of approved mini PCI Express cards, otherwise, I'd just order a Dell part that has the same Broadcom chip and costs less.

I wouldn't mind that either. So far the 1x1 has been OK, but it does not connect higher than 72mbps according to my router, but I havent really put it thru its paces.

 

I was also unable to choose the 2x2 when ordering my configuration, Win7 Home config only had 1x1 available, but the WIn7 Pro option had 2x2 as an option. This was on the Canadian Lenovo store. I would have gladly paid the difference.

 

I also thought of trying to get one on ebay, but the BIOS whitelist worries me... But I wonder about the second mini-pci-e slot, used for the WWAN. I'm never gonna use that, could a generic card work in the second slot? There is antenna hookups there as well, though I wonder if they are tuned for cellular use, not WiFi?

Well, I thought I'd try the experiment with the WWAN slot, I remembered I had a card from an old HP, so I put it in that slot.

 

There is no BIOS restriction message, but the old HP adapter is also not detected in WIndows. I have another one at work I will test tomorrow.

I don't think the card from Dell or HP will work, as far as I can tell lenovo approved cards have a firmware installed from lenovo which the BIOS detects on boot. FYI, 60Y3251 costs $53.50 from IBM maintenance.

Re: Trying to find the Broadcom 2x2 WLAN adapter for X120e

Thanks for the tip, Maliha! I will call them tomorrow to check on availability.

 

Another option I'm considering is replacing my D-Link DIR-655 router with an ASUS RT-N56U. It's about $130, so obviously a more expensive route. However, it got a great review at smallnetbuilder.com, and one of the users on their forum mentioned that they had an X120e with the 1x1 Realtek card and got great wireless signal all over their house with it.

Re: Trying to find the Broadcom 2x2 WLAN adapter for X120e

What is this IBM exchange thing? Can I "trade in" my 1x1 card for the 2x2 card and get ad iscount?

Re: Trying to find the Broadcom 2x2 WLAN adapter for X120e

I created the post on SNB about the ASUS RT-N56U.  I've not had time to update it, but, have more info on the set-up. 

 

1. I took Tim's advice and bought LAN Speed Test software.

2. I updated the drivers from the Realtek site: 1005.15.223.2011.  This is newer than what Lenovo is pushing down from their site.

3. Bios is updated and everything else Lenovo pushes down except for the Realtek driver.

 

Running the LAN Speed Test, with the X120e cord powered, is showing: 70 Mbps Writing, 61 Mbps Reading.  What I'm not sure about: Does this mean a throughput of 131 Mbps?  If it does, then my understanding is the 1x1 card is maxed out at 150 Mbps, which is pretty good.  I hope someone more knowledgeable can confirm.

 

One thing about the 1x1 card is, unless I'm missing something, it only works in the 2.4 Ghz mode.  The ASUS does both 2.4 & 5.0 Ghz.

 

I'm under the impression the advantage with the 2x2 is higher rating at 300 Mbps and could do 5.0 Ghz.  I have not found a spec that confirms this though.  From what I read, 5.0 Ghz has a lesser range, so, not really sure if this is a negative.

 

I was thinking of doing the same as you and buying the 2x2 card and upgrading.  But, based on what I'm seeing, you're money would be better spent on a new router.

 

Highly recommend buying LAN Speed Test.  It confirmed how bad by powerline network adapters really are.

1x1 (aka 1T1R) means you have a single antenna available for transmitting and receiving. 2x2 (aka 2T2R) means that you have two antennas available for transmitting and receiving.

 

In general more antennas is a good thing with WiFi connectivity.

 

BTW, as much as I respect Small Net Builder reviewing in general, their WiFi kit reviews have been showing results for quite a while now which vary VARY CONSIDERABLY with real world experiences reported by users.  This suggest to me that their WiFi testing approach is not capturing all the variables that actually impact WIFi performance, so you probably need to be careful with their WiFi kit recommendations.


For instance the Linksys e4200 is capable of 3T3R operation, but have rated the AUS  RT-N56U router (which only does 2T3R) higher than the e4200.  Userreports are suggesting that the e4200 significantly outperforms the RT-N56U router in actual field use!.

 

Cheers,

But the 1x1 Realtek card has two antenna leads connected to it.

Hello,

 

You may want to consider using an external USB adapter, ZacMatic.

 

I just received my X120e (MT: 0569-CTO) a couple of days ago with the 2x2 11a/b/g/n Wireless LAN PCI Express Half Mini Card Adapter in it, and when connecting to my home WLAN I receive a 104Mbps connection about two feet away from my access point (Netgear WNDR3700).  Using a Linksys WUSB6000N Wireless-N USB Adapter with Dual-Band ver. 2 with the X120e in the same location gives a 300Mbps connection.

 

So far, I have not done much other than get Microsoft Windows and the various ThinkVantage programs updated, but it appears an external USB adapter provides (or at least reports) a faster connection than the internal card.

 

For most uses, I suspect this is not going to make too much of a difference, but if you are doing something that requires a more robust connection, like downloading large files, than using an external adapter may be a better solution for you.

 

Regards,
