Why have to turn off WIFI when start LabVIEW ?

[BigDrum]

Installed Labview 2016 (64bit) and start ok in Company using company wifi. But after back to home, connected to home wifi, when start Labview, it stuck at the starting page. As soon as I turn off Wifi, Labview started. Looks like Labview need connect to NI to validate something (license?) But somehow my home network block it. What I can do to (in Wifi setting or?) ? Please help, thank you !

I've never seen that problem myself.  And I have rarely heard anyone one complain of it.

Is it truly wifi?  Or is it your home network?  If you hard-wired in an ethernet connection to your home network, does it cause a problem?

But I do feel like I have heard of a similar situation one time before that was related to the news feeds that show up in the getting started window.

If you go to Tools >> Options >> Environment, try unchecking "Disable ni.com updates in Getting Started Window" and see if that helps.

My Home network. And I have other laptop (PC and Mac) never have this problem at home.

Tools >> Options >> Environment, try unchecking "Disable ni.com updates in Getting Started Window"   it is already unchecked. But "Lock automatic tool selection" is checked. I will uncheck it and test.

One other option could be printer drivers in the past. LabVIEW does a printer enumeration during startup and some printer drivers can actually take a long time to respond when they can’t talk to the device they think should be there. There might be some code that fails early in the printer driver when there is no network but will simply wait for minutes to get a response from the non existing device otherwise!

uncheck "Lock automatic tool selection" did not help. Also I found it only have this problem when I connect my home wifi which is AT&T high speed DSL. If I connect personal hotspot through my iPhone at home, I do not have this problem. Looks like it is related to the setting of my AT&T wifi, it works for other web site, but somehow when Labview startup trying to connect (to ni.com?) the connection was blocked and Labview wait for ever, cannot start. But if I enable WIFI, Labview startup trying to reach some URL and only my AT&T account at home block it.

If I disabled WIFI (not connect to internet), Labview startup without problem ( but I need connect to network to run).

Now if I want to work at home, I have to

     1. Disable WIFI

     2. Start Labview

     3. Enable WIFI

     4. Run the program writing in Labview

So if there is a way to disable Labview from trying to connect to network when there is WIFI, it should be able to resolve my problem. And idea ?

Probably you are correct. Today I wait longer enough (one minute) Labview started. Thank you !

After I switch from AT&T DSL to Comcast, the problem is gone.

I guess it is related to the wifi speed. Since AT&T DSL is slow, LabVIEW verification is timeout/hang.
