Will only lenovo branded intel WiFi link 5100 work with x100e?
I searched " intel wifi link 5100" on ebay, came out about 100 results with around $10.
I wonder if these item will work with my x100e, or I need to look for lenovo branded specifically.
Can you post a little bit more detail information about how to wrap up the antenna with 5100?
please advise. thanks

I tried installing both a generic OEM Intel WiFi Link 5100 half-height mini-PCIe WLAN card and the Lenovo-branded version (P/N 43Y6517) in my ThinkPad X100e. The generic card reported a BIOS error, while the card with the Lenovo part number works flawlessly.
The antenna connectors used on both the Realtek and the Intel card are the same and can be easily removed by gently pulling up on them while rocking them back and forth a little or by sliding a jeweler's flat blade screwdriver beneath the cable where the metal antenna connector is crimped on and using the blade as a lever to pop the connector off.
Once the antennas are removed, you can use a 0 (or perhaps even a 00) sized Phillips screwdriver to remove the single small screw which locks the mini-PCIe card in its slot on the X100e's system board. The same screwdriver tip used to remove the X100e's bottom access plate should work just fine.
Reconnecting the antenna is done by placing the lining up the antenna connectors and lightly applying pressure with a fingertip.

So in the main half-height slot a Lenovo-branded 5100 (43Y6517) will work without any sort of pin covering?
Did anyone try using a generic 5100 card in the WWAN slot with pin 20 covered? According to ThinkWiki that is supposed to work in the WWAN slot, and generic Intel 5100s are dirt cheap.
I know goretsky you said that you tested out a half-height generic Intel 5100 but it sounds like you tested it out in the main Wi-Fi card slot where the RealTek card normally is rather than in the WWAN slot.
I am also somewhat curious as to whether something like this: http://www.newegg.com/Product/Product.aspx?Item=N82E16820183252
would work with pin20 covered in that WWAN slot since I have it empty anyway.

In the half-height MiniPCIe expansion card slot I was able to use a Lenovo-branded Intel WiFi Link 5100 (FRU 43Y6517) without having to tape over any of the pins.
I tried using a regular OEM full-height Intel WiFi Link 5300 MiniPCIe expansion card (533AN-MMW, I think?) in the full-height MiniPCIe expansion card slot normally used for the WWAN card and it did not work. I tried taping pin 20 over, but was not very succesful in doing so, I guess.
Unfortunately, I have no idea what would happen if you placed a PATA or a SATA SSD in the full-height MiniPCIE expansion slot with pin 20 taped over. Perhaps you could try it and let us know the results?

Thanks for the info. Where did you guys get the Lenovo 5100 [43Y6517] from? I tried ordering one off eBay but that silly Chinese seller sent me a completely different item and now I have to deal with filing a claim.

I purchased mine from a seller on eBay. It was shipped from Shenzen or Hong Kong, I think.

I finally got the Lenovo/Intel 5100 [43Y6517] I ordered today and just installed it. It was an extremely easy install that only took a couple of minutes. All you really need is a basic screwdriver and maybe some tweezers or something to pop out the antenna leads.
I'm glad to report that this has more or less solved any problems I ever had with my x100e - though...I wish I didn't have to go to such efforts to make it work...
I ordered the 5100 from: http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=250685473475
My item arrived professionally packaged and shipped quickly via registered mail. I highly recommend that anyone with an x100e replace their wireless card with FRU#43Y6517 from that seller.

Oh man, this is wonderful! I'm excited to get this sorted out, going to ask my local computer shop if they can possibly get one in for cheap, too, before I order one on eBay. Wireless on this thing has been an absolute NIGHTMARE, and it's comforting to know that it's not just drivers or me going insane, but that the wireless chip itself just blows.
Question: why isn't something done to improve the card, and is Lenovo possibly going to do something with respect to warranty? Given the number of problems people seem to be having, this is seemingly a rather widespread issue... while I understand that it does work, it's the point that it doesn't work that well at all, even in Windows, frequently turning off, dropping connections, and generally glitching the heck out. This is a bit of a frustration on a device billed as a "business entry ultraportable," by Lenovo, where the whole purpose is to be able to use wireless and not be tethered to a desk.
With that said it's been a wonderful system, and I'm glad I got it, it's more just what I consider a rather valid gripe =)
