Lenovo Y50-70 WiGig upgrade

2017-02-22, 22:44 PM

As the title says, I'm trying to upgrade my laptop with WiGig support, and so far I have encountered only obstacles.

 

I have bought a Dell wireless docking station WLD15 (which uses an Intel 13100), a 60 GHz antenna module from a replacement LCD cover for a laptop model with WiGig support (Dell E5440), and of course, an Intel 17265.

 

The first problem is that Intel 17265 uses an M.2 key A (only) connector, but the Y50-70 has an M.2 key E (only).

Before I go any further let's take a look at the differences between M.2 key A and E.

The Intel 17265 needs only PCIe0 for WiFi (n/ac) + PCIe1 for WiGig + USB for Bluetooth ( + DisplayPort channels for ???). 

Third problem could be BIOS blacklist of unrecognized adapters, which I heard is a common problem ... 

 

Anyway, I'll keep you posted on any progress. While adapters are on their way from China, feel free to share your thoughts.

Success.

 

After a lot of waiting, I have eventually found an M.2 to mPCIe adapter on ebay. Coupled with 2 x Dell wireless docking stations WLD15 (also bought on ebay), I now have the complete setup to attempt the upgrade.

 

First we'll connect the M.2 to mPCIe adapter to the mPCIe to M.2 adapter, to interconnect host PCIe0 to the PCIe1 (WiGig) of the M.2 connecter, and then Intel 17265 adapter on top, only with USB (bluetooth) and PCIe1 (WiGig) connected. No PCIe0, so no normal WiFi (802.11n/ac).

Don't make the same mistake I did. You can't improvize the antenna. You need the Intel® Wireless Gigabit Antenna-M 10041R module, which is an active module (i.e. over the coax, both power and control signals are sent to the module).

 

To install the assembly in the laptop I had to remove the subwoofer, and I have placed the WiGig antenna under the edge of the palm rest, next to the SSD, facing the array up. Seems to be a good spot, getting a strong signal from the dock placed in the corner of the room, 3 meters away, up on a tall furniture.

I have converted 17265 from M.2 key A to key A + E, and it worked, it was dedected by the system, however, it won't boot up because it is not white listed in BIOS, giving an "unauthorized WLAN card" warning.

When I powered it up, the system did boot up without any "unauthorized WLAN card" warnings like before, and the WiGig adapter did not show in Device Manager. This means the second PCIe lane is not connected to the M.2 connector in Y50-70. Great job Lenovo.

The Intel adapter is fine. I have connected it to another PC with mPCIe to M.2 adapter and it worked.

 

And since bad news don't come alone, I can't find the M.2 to mPCIe adapter anywhere. They are all sold out.

The only think left to do, is fiddle with wires and get PCIe0 (the only one availabe) in the system M.2 connecter connected to the PCIe1 of the Intel 17265 (the WiGig chip). I'm really not looking forward doing this, since there are very slim chances that I'll be successful.

 

I have reached a dead end.

@Chris_DB so you basically sacrificed WiFi, right? I am considering putting a 18260 in a different machine, yet also with E-key m.2 slot. Is there some way to know whether both PCIe lanes are wired to the m.2 slot via software (before purchase)?

Yeah, I sacrificed Wi-Fi. I'm still debating what low profile USB Wi-Fi to use.

I don't think there is way to tell if the PCIe1 is connected via software, unless there is something connected to it, in which case you could use HWiNFO64 to check.

Try take a look under the hood and see if there are any visible traces leading to PCIe1 pins of M.2.

Also, try ask the manufacturer.

Edit: Oh, by the way, I ended up buying 2 WLD15 docks, because the WiGig antenna in Dell E5440 is not compatible with the Intel adapter. The antenna has to be an Intel® Wireless Gigabit Antenna-M 10041R, which can be found in WLD15.

@Chris_DB thank you very much for your answer!

 

I tried HWInfo64, and it indeed doesn't show unconnected PCIe devices. Looking at available photos, it is impossible to tell whether second PCIe lane is wired to the slot or not, and schematics are obviously unavailable.

 

I also use WLD15, btw. For my Thinkpad, I pulled the 10041R antenna and cable from newer Dell LCD cover.

 

How's your WiGiG reception in laptop body, btw? How far are you able to use it before it reports poor connection?

I doubt all PCIe lanes are used in your laptop, but who knows.

 

The signal is pretty bad. You'll be able to use it only in the same room with clear line of sight between antennas.

Just by walking in front of the laptop, I get a low signal warning.

I have placed the antenna array facing upwards in the right side of the chassis, like shown in the pictures. If I hold my hand on top of where the antenna is, I get disconnected, so do not place it under the palmrest.

I haven't experimented a whole lot with signal reception, but it seems to be passing through a thin sheet of aluminium, because my laptop has a metal chassis.

@Chris_DB thank you for sharing.

 

The behavior you describe is normal, even installed in manufacturer-specified location in the display lid, WiGiG behaves absolutely the same. It is not supposed to pass through walls, human body, liquids, etc. I also had some weird problems with LTE & WiGiG coexistence - which were resolved by switching WWAN main & aux cables.

hi can i speak to Chris_DB

I have just signed up (i never use forums)
 
i see you said you buy 2 WLD15, to take the M10041R antenna because the wigig antenna in the dell was no good?
 
I found this on ebay -which is a unresponsive seller (never answers mail) https://www.ebay.co.uk/itm/Intel-Wireless-Gigabit-Antenna-M10041R-Module-Specifications/232472021357?hash=item362069896d:g:SxoAAOSwfi9ZqKMb 

so I think also i may buy a second WLD15
 
I must ask you, when you opened you WLD15, was there one or two antennas... I ask as my one has one antnna, but it certainly looks like a second (dual) antenna can be fitted, perhaps to inprove location, direction?
 
I wanted to ask you, in your experience, why did the antenna out the dell laptop not work
 
 
I have a M4800 which origianlly had wigi, using a dw1601 card, but I noticed that looking at the dw1601 card, it had 3 pins/sockets,  one for wigig (a tiny tiny tiny thin blue wire) and two pins/socks for wifi/bluetooth (aux and main)
 
the pins/sockets for the wigi was incredibly smaller than the aux/main
 
I had to buy a 1 inch wire from chnia ebay, that was male to female and changed the sizes, but i had problem (repeat orders and massive time waiting delivery china to uk) - as i did not know the specifiic official names of the pins/sockets or sizes
 
now i myself found the dw1601 antenna (i dunno the original dell antennas name) - but i noticed the tiny pin wire doesnt fit in my intel 17260 wigig card (ps the 17260 tri band m.2 wigig card has 3 pins/sockets, which are all three very small)
 
so i suspect i will need to purchase another adapter wire but to which size or name i dont know
 
i am also waiting on production of m2mp3-a cars in a few weeks, as my m4800 is mpcie style / msata
