Keeping 4g active when connected to wifi with no internet

[RPW]

K0ua pretty much summed it up. Problem is phones don't have routing accessable to the user. In your case I believe that you also have devices such as laptops on your home network and you use your router to allow them to access the internet. If that is correct and your using the router to connect to internet via a USB cell radio such as the Verizon one then let the phone connect. It uses the same data plan.

If your printer is a modern printer with wifi direct capability, you might be able to set up your phone to talk directly to printer over wifi direct and not use your home network.

If your printer is a modern printer with wifi direct capability, you might be able to set up your phone to talk directly to printer over wifi direct and not use your home network.

The printer is still going to be on the home network subnet, and so is the phone. The IP addresses still have to come from a DHCP server for both the printer and the wifi portion of the cell phone. The printer could have a static address, but how would you set a static IP address in your cellphones wifi section? These phones are just not set up for routing.

And the basis of the problem is he cannot specify where port 80 traffic will go out. It will always choose the wifi network as its first choice, and will receive its IP address and default gateway from the DHCP server in your home network, Usually your router unless the wifi network is down.

The idea of setting up a Data "modem" on the same 4g network as the phone uses, and shove that into the WAN port of the router is a viable idea and would work. So in effect the 4g carrier network becomes your WAN for the home network.

This problem is going to be resolved by another 4G network. I bought the ZTE Mobley from AT&T, and I will attach that once I get a different router with usb connections, that will put a home network back in place.

It is a shame though that I couldn't make the phone use it's own 4G when hooked to wifi. It seems, at least to me, that is a deficit design that wasn't a problem until the carriers have came out with all this unlimited 4G plans.

Yep, things change. We all think nothing about making "long distance" calls (what ever those are) every day all day. When I was a boy, my parent would have taken me out to the woodshed if I had placed a "long distance" call on our home phone. It just wasn't done. Too darn expensive. Of course a long distance call was a call to my buddy who lived on the other end of our 80 acre field. I could see his house. but a 3 minute call was probably 3 or 4 dollars as he was on a different exchange with a completely different company. A call to any of our relatives in California was reserved until someone died. Now we just pickup and dial away and it doesn't "cost" anything. Just pay that huge monthly bill. :laughing:

Using Voip, my total phone costs from April 1/2017 - June 22/2017 Premium | Calls: 202 | Duration: 10:50:11 | Total: $6.117

All calls North America same charge, overseas slightly higher.

You can even get an App for your phone that lets you connect to your voip account, out going calls are made via call back which then gives you a dial tone.
