Rand McNally cant get browser to open to sign into wifi

I have a TND 740, Im trying to update it via WiFi at both loves and Pilots who both require you to sign in via the webpage log in. The problem is when I connect to the WiFi, the browser window pops up but it's blank, just a white page..

How can I force it to open the log in page? I've tried at multiple truck stops and it simply goes to a white page and never lets me log in. I know the WiFi locations are fine as I use them on my laptop and tablet..

It used to work fine but just opens a white screen.. Any ideas how to get it to let me open the log in page?

 

I can't even get the webpage login to load. It loaded previously.. Happens at both loves and P/fj.

It's not the wifi I know that. It connects just fine to the wifi but the actual lig in screen won't load. It pops up and the little load bar starts loading then just a blank page.

Well the problem is, it's not really a tablet. It runs on Android OS but you don't have access to the web browser or anything like that. It only gives you very limited access to the web browser via a pop up when it connects to WiFi. You dont however have the ability to type in a browser bar or anything like that to go to a random webpage.

Basically they gimped the Android or to stop you from having acess like a tablet would. That way they can sell the other "tablet" model..
