Labview2017 will disable my wifi connection
Hi, after strictly NIDAQmx only installation (no LabVIEW or anything else) there are 8 NI services (see attached picture). You can easily count number of combinations I need to proceed (disable one service, turn laptop off, turn it on, go to sleep mode, wake-up it, check wifi). I am really sorry, but NOOO, this has to be done by NI guys.
This issue costs me several days already and is better for me to downgrade to LabVIEW 2016 and to old DAQ from 2016 where are no such troubles. Pitty nobody at NI takes care about this since it is complained so many months already by many people in this thread and also here (they claim it is solved HA!): https://forums.ni.com/t5/LabVIEW/Labview2017-will-disable-my-wifi-connection/m-p/3956515/highlight/f....
After very detailed description this week NI support asked me how much it bothers me. Sad. Are you serious NI support? Am I alone who is struggling with this?

Hope nobody feel I do spamm the thread. I have been working constructively with the support people again and again. You better don't ask me about total number of hours already spent on this issue with the support people and mostly on myself... No I don't like the idea to have 2 laptops for my everyday job: one for NI SW with no chance to use WiFi after sleep mode and another lapotop for the rest of SW. Too expensive, too uncomfortable.
What I investigated today can be seen on the attached figure. Could other people suffering with the same issue try to disable following services and report here the status with WiFi?
-NI PXI Chassis Management Service
-NI PXI Resource Manager
Please note: there is strictly NI DAQmx only (really nothing else from NI) installed on my laptop to isolate as much as possible the source of troubles, what is by my opinion NI DAQmx.

Not sure but I would think that the Chassis Management Service is probably not the problem (you don't show a column where this was enabled and the PXI Resource Manager was not and it may not be possible to have it enabled without the PXI Resource Manager) but I definitely would expect the PXI Resource Manager to be the primary suspect.
PXI is for the most part a different mechanical implementation of the PCI bus specification with additional hardware. The NI PXI Resource Manager has to interface on a very low level to the Windows device management in order to perform its services and despite its name it is also used by NI for the management of PCI hardware resources for their PCI and PCIe cards. It's a feasible assumption that the problem lays in here. It could be a power management event that is not correctly forwarded through the driver stack or it could be a specific issue in one of the chipset drivers that makes itself apparent when the NI PXI Resource Manager is hooking itself into the driver stack.
This kind of feedback is definitely the productive kind as it pinpoints the problem to a specific software component. Now NI will need to reproduce this with a hardware setup that is the same as your computer so they will need to have a very specific hardware report for your system. The computer model alone won't be enough as the chipset and according peripheral chips often are changed even within the same model line due to different CPU models used, bug fixes or also because of redesigns of the hardware to mitigate EOL (end of life) notifications from component manufacturers, or also simply to safe a few cents on a specific chip.
If support hasn't asked you yet for it, I would go into NI Max and generate a detailed system report for your system that hopefully contains all the relevant information about your system hardware and send it to NI with your service request number.
Ni support asked me to install by pressing Deselect all button, and then checking NI-DAQmx only, no additional items. Everything installed, WiFi issue is here, but no MAX.EXE installed as you can see in MAX directory content. No chance run NI Max and generate a detailed system report.
Anyway I can provide service tag of my Dell Latitude E6230 (old, heavy, not sexy design, but absolute reliable, durable and fully functional) I offered to lend my laptop to support guys in Europe (no idea in which city they are sitting now as responsibilities and structure are changing each few month recently at NI Europe now) but they dont want it and informed me they will forward all information to US guys.

Never used the NIPM so far but there should be somewhere the option to also install NI-MAX. It's usually needed anyhow on machines that use DAQmx as you will want to discover NI hardware and optionally pre configure it. Writing DAQ application that can discover all the hardware on their own on a freshly installed system and properly configure it is pretty time consuming and error prone.
After that there should be an option in NI-MAX to generate a full system report for support requests.
The support centers in Europe can not do much with your computer except send it to NI corporate for debugging. Except possibly in India they do not have low level system software development outside of NI corporate. Debugging kernel drivers is however something that can only be done on specially instrumented hardware with access to the full development sources for those drivers.
So your computer would have to be send to NI corporate (or maybe India) completely wiped and reinstalled with a special debug build of Windows and then a software developer could start debugging the issue. This would most likely mean that you will have to live without your computer for many weeks to months. In addition there could be accidents during this that may damage your computer or it may get lost on the way and that is something NI does definitely not want to risk.
