Hi guys and gals :)
Sorry for coming up with such a probably weird and quirky issue again and also I really tried my hardest with the title here, so please have some lenience with me here... 

I startup the drone with an LTE module (v2) attached and a camera connected to the VOXL-Flight's USB port.
Scanning wifi-IP's this VOXL doesn't show up anymore and I can't connect to it through a GS nor SSH.
Now the thing is, **as soon as I pull the camera from the VOXL's USB** the wifi on the VOXL starts up and it will connect to a GS and I can SSH in normally.

I tried plugging the camera back in and the wifi (wlan) on the VOXL actually ceases to work again.

Are there possibly any resource conflicts going on here?
Should I try connecting the camera to the LTE module instead? (As I understand this doubles as a USB-hub?)

thanks for any insights.
cheers

@m4v3r Could you post a picture of your setup so we can get a good idea of what you're working with?

@tom yes, will try and do so tomorrow.

actually it might not be feasible for me to snap actual photos I just made an image showing the basic concept

One more thing to add I can think of is
that on another drone the same setup but without the LTE module is working normally.
Please tell me if it would make a big difference to have actual photos and I'll see what I can do... ;)

@m4v3r  The LTE module shouldn't affect it, unless it is a power issue. I'll ping the team on this one.

@m4v3r @tom Have you looked at this thread? Seems similar

Hey,
just wanted to give an update it looks like the problem was a hardware fault.
The behavior stayed the same after detaching the LTE and the setup works on a different VOXL Flight, so yeah...^^
cheers
