Just got my new Quadzilla installed today, should have done it some time ago.

 

Just one thing I did not see mentioned in the instructions for the IQuad or anywhere else.

On the IPhone you should change the wifi settings for the IQuad.

   It should be set to manual instead of automatic in the Configure IP setting

Set the IP Address to (in my case) 1.2.3.14

the Subnet Mask to 255.255.255.0

and leave the router blank

 

This will allow the Iphone to connect to the Quadzilla and maintain LTE connection for interrnet.

That ... That's great. Thats fantastic. I will have to get that published as quick as possible if it works for everyone. 

-Thanks again, 

Done here too...

 

Even changed the topic title so people can find this. Thank you @J_Harms

Tell your wife thanks!

Was there any kind of follow up with this. 

It does work! Just did mine today. iPhone 11. iOS 15.6.  Links backup automatically when you open the app.
