As my early post on 2/1/2014 pointed out, ever since first assembling this NUC with a Intel Wireless-AC 7260HMW, its connection range at 2.4GHz has been very short, so much so, unable to connect to either of the medium distance 2.4GHz APs (4m away thru 1 floor, 1 or 2 walls of a flat block) at either of the 2 locations I live at, yet my Nexus 5 smartphone next to the NUC, connects solid to either AP, as did a Toshiba L850 1D5 laptop with Atheros WiFi card, connects without problem. In 2014 my then 7 year old laptop with old Intel 3945 Wifi-G slightly better than NUC. As a result, I have NEVER been able to use my NUC WiFi for direct internet connection.
The IMEX connections to the 2 antenna fit well. Intel Proset in the NUC still shows TX power 100% 32mW.
Heard others experienced same problem on NUCs. Can you advise the Rx sensitivity of the 7260HMW and what gain (dBi) the D54250WYK internal antenna have ?
I had wondered if the range would be improved by fitting external antenna ? I see external antenna advertised upto 15dBi. Is there any recommended max dBi gain for the external antenna ?.
I find it mystifying a Nexus 5 smartphone with far smaller antenna than NUC, has far better range. Why should that be ?
If after testing, external antenna found to have surplus gain, If its feasable, I want to fix the RP-SMA bulkhead connectors in a good location on the NUC case. Have others found a good location ? If SMA too big, what about fitting a pair of IMEX bulkhead sockets ? ..of course that will add more signal loss.
I wondered if a new driver may fix issue or the mentions of revised 7260 card, but did not find other posts on this forum specifically addressing this issue.
Thank you.
