Subject: DeskMini 110: M.2 WiFi + antennas - what to buy?

Hello,

as the DeskMini 110W isn't available here I bought a DeskMini 110B. The exact model name is DeskMini 110/B/BB/EU.
I'd like to expand it with an M.2 WiFi/Bluetooth card. 

I'd like to have WLan 802.11ac (2.4GHz + 5GHz) and Bluetooth 4.0. Getting an M.2 card that fits to these requirements is no problem but I don't know which antennas to use.

Does anybody know which antennas will fit into the housing of the DeskMini?
It would be interesting to know which combination of M.2 card and antennas is working fine.

Thanks for info.

The antennas themselves are pretty much standard. It's the pigtail cables that you have to worry about.
These are the 2 I'm considering:

I'm not sure what the cable length is that comes with the 110W, but I saw somebody mention that he had a hard time getting the included cables to reach the connectors when the cpu cooler was in place.
So I'm guessing a foot in length should provide enough leeway.

Thanks for posting this, I have a DeskMini 110W, and I can tell you the parts you linked to are correct. I meant to reply to that post, but it got lost in the forest. Embarrassed

Another antenna kit, that I stole from a page in your first link above, looks perfect and seems to include both parts:

https://www.amazon.com/Wi-fi-Antenna-RP-SMA-Antennas-Cables/dp/B00A4I3AGE/ref=pd_sim_147_2%3F_encoding=UTF8&psc=1&refRID=RFB8406YAA759V2JTJT6" rel="nofollow - https://www.amazon.com/Wi-fi-Antenna-RP-SMA-Antennas-Cables/dp/B00A4I3AGE/ref=pd_sim_147_2%3F_encoding=UTF8&psc=1&refRID=RFB8406YAA759V2JTJT6

Regarding the length of the cables from the antenna mounts provided with the DeskMini 110W, they are about eight inches in length. Same as the kit in the link above.

Routing the cables is not that difficult, just route the cable between the CPU cooler and the board's IO ports. I don't use an Intel stock cooler with my DeskMini, and I was able to connect the cables fine. Not much slack but it was a perfect length IMO. I even have an M.2 SSD in the M.2 slot, right above the WiFi module.

12 inch cables would make it easier for anyone to connect the cables, but then some users would complain about the cables being too long. Cable length is subjective, everyone has a different "perfect" length.

The specs don't actually mention which frequencies those antennas are designed for. It only says "works with Wi-fi and Bluetooth signals", which could mean it's only designed for 2.4GHz and not 5GHz. In fact, it doesn't even say dual-band anywhere in the description.

Good catch, the description farther down on the page mentions use with, "... Intel Centrino Wireless N series cards". Those are only single band, 2.4GHz WiFi cards. So not for use with dual band WiFi adapters, unless they failed to include that in the specs. Normally that means the support is NOT there.

Care also must be taken with the connectors on the cables, there are different types depending upon the WiFi adapter being used.

Sorry, not really a WiFi person. My home is wired with Cat 6 cable, so I'm spoiled, no WiFi for me. I tried it on the DeskMini 110W, and it works, but WiFi can't be matched with wired connections. Even in the USA, where are Internet connections are not the best in the world.

For me, the search for the right  cabel was an odyssey, i buy 3 times the "right" cable and non of them has the right connector.
I have an Intel Ac8265 in my Deskmini H110.  The only cable with the correct connector was an  http://www.delock.de/produkte/F_702_Antennenkabel_88815/merkmale.html" rel="nofollow - http://www.delock.de/produkte/F_702_Antennenkabel_88815/merkmale.html
This set has the MHF4 connector that is needed for m.2 Wifi cards. The MHF4 connector was smaller then the normal IPX on PCIe Wifi cards.
And the other problem i have with wrong cables, was the lenght. When use the orig. holes in the Deskmini, the cable lenght must be not shorter then 20cm. Most of the MHF4 cables only 15cm and thats to short.

" rel="nofollow - Hi guys,

I am building a deskmini with a i7 6700 (hope it won't run too hot) and I need advices.

For the wifi card, is the "INTEL Dual Band Wireless AC 7265 2x2 AC + BT M.2", compatible ?

https://www.amazon.de/gp/product/B00U8IUTNM/ref=ox_sc_act_title_1?ie=UTF8&psc=1&smid=A3JWKAKR8XB7XF

or is it simpler to go with a USB wifi card ?

Thanks for your help

" rel="nofollow - I am also interested in getting a wifi card, can anyone point us to which model?
Does it really need to have external antennas or will it work without them?

I'm still trying to figure this out myself.  Apparently some Intel M.2 WiFi/BT adapters use a smaller connector than other PCIe WiFi/BT adapters.  So while the antennas that stick out of your case are interchangeable (as long as they support both 2.4 GHz and 5 GHZ, that is) the leads that connect them need to have the smaller connector to properly snap onto some Intel cards.  Other adapters (like Broadcom chipsets) use the standard snap connectors, larger than the Intel ones.

That seems to be the problem folks are having -- getting the wrong size snap connectors for their M.2 WiFi card, and not ensuring that the antennas that stick out the back will work or support both 2.4 GHz AND 5 GHz.  Apparently some of the ones advertised as 5 GHz are just for 2.4 GHz so your performance will suffer.

And yes, you absolutely need to have the antennas sticking out the back.  Just leaving the antenna leads sitting in the case will drastically reduce your throughput and WiFi range.

That Intel card looks like it should work.  Just make sure you get the leads with the smaller clips on them, not the standard ones that work with most other M.2 WiFI cards.

I believe the larger snap connectors (that don't generally work with Intel WiFi cards) are IPEX or MHF, and the smaller snap connectors that work with many Intel M.2 cards are MHF4.

The Intel WiFi card supplied with the DeskMini 110W, is the Dual Band Wireless AC 3160:

http://www.intel.com/content/www/us/en/wireless-products/dual-band-wireless-ac-3160-bluetooth-brief.html" rel="nofollow - http://www.intel.com/content/www/us/en/wireless-products/dual-band-wireless-ac-3160-bluetooth-brief.html

It is important to know there are multiple form factor models of this WiFi card, and the DeskMini 110's mother board is designed to work with only one of them.

That is the M.2 2226 version, the smaller one whose picture is on the right in the document above.

Any WiFi card that is purchased separately must be the same form factor as the M.2 2226 version of the 3160, or it will not fit correctly in the M.2 slot provided for the WiFi module.

The antenna connections on other WiFi cards may be different as well, and matching the cables and antennas to those cards, if none are supplied with the cards, must be done carefully. The antenna mounts themselves may not fit in the holes provided on the DeskMini 110 case, as their are multiple antenna connection types.
