voxl-wifi and voxl-modem running concurrently

[[[global:former-user]]]

Hello,
I am using system image 3.8.0 on my VOXLCAM. I am using VOXL LTE Modem v2 for remote connectivity with my QGC via OpenVPN which works perfect. I have system startup service enabled for Openvpn as well. I have been noticing issue with my LTE modem being very inconsistent w.r.t connecting to my 4G network. My system has wifi always enabled either in station/AP mode along with voxl-modem which gives me wwan0 interface. Sometimes VOXLCAM fails to connect to my 4G network and whenever I check voxl-inspect-services I see voxl-modem is not running.
My queries :

• Is there any concurrency issue with wifi and LTE running together?
• My 4G network is quiet strong so VOXLCAM on each bootup should be having good singal strength. So how to make LTE connectivity consistent so as to operate my drone reliably for BVLOS missions?

@Aks If you're running WiFi in station mode and LTE, linux can get confused on how to route the traffic. Are you actively using both WiFi and LTE?

@tom I am actively using both wifi and LTE. When I use my VOXL in wifi station mode I have problem of voxl-modem not providing me wwan interface on boot up sometimes due to which I was unable to connect to remote GCS.
I am seeking for information regarding two interface handling by VOXLCAM module. Is it fair to use wifi in station/AP mode while LTE is also active or I need to disable voxl-wifi completely to get reliable results?

@Aks The wwan0 interface enumerating should be unaffected by having WiFi enabled / connected. Are you saying that when you run an ifconfig that you see no wwan0 network interface listed? Or that the interface is there but is not getting an IP address / not getting a network connection, e.g can't ping www.google.com

@tom I don't see wwan0 interface after doing ifconfig so couldn't ping google.com as well.
