WRT1900AC integration with Linksys Hosted Router Management?

Question

I recently purchased a new WRT1900AC.  When I first started it up, I was prompted to set things up with a preconfigured Router Name and network Names, did so, and then quickly realized that I had made a mistake since everything on the wired portion of my network was already configured and working with the router that had just died and was being sent to router hell for its' sins.  I got everything working the way I wanted it, including working wireless access via the Android support app that lets me administer the router from my Samsung Galaxy IV smart phone.   The one limitation I face now is that the Linksys hosted web site that took my setup information initially, no longer knows about my router, so I can't log in to it from the network at my local community college where I'm working out at the fitness center and connected to the internet via their wireless network, or when I'm using Verizon's 4g network in my car.  I have some security concerns about giving the Linksys hosting site access to my router that were raised initially when I tried logging into their site via my 64bit Internet Explorer 11 with Norton Internet Security running which told me that the site certificate was being hosted somewhere other than where I was trying to log in, or was an invalid certificate and blocked me.
I relly don't know how to most quickly and securely resolve this problem since I do not want to mess with my current router configuration, I just need to get the smart phone app which works fine within my local wireless network to be able to contact the router over the internet without having to set up my own VPN service or something like that so that I can come in to the network first, and then access the router.  I believe that everything is set up except that the MAC address information registered on the administration site is associated with the default network names, and my attempt to set up the software there after I had congigured the network the way I wanted it got blocked by my own network security during the attempt.  At any rate, I'm stuck, and do not know quite how to best go about correcting my difficulties without starting over from scratch by resetting the router, which is a real **bleep**.
I'm also not completely sure that the out of the box software and procedure for using it has not been compromised or open to some kind of compromise that would open up my network to unauthorized snooping or worse via the standard site.  if you understand the issues, please advise.  should I just be content with using my cell phone within range of my own router to administer things?  If I'm not, since the administration site knows me but does not seem to know my router unless I'm in my own network, how do I go about reconnecting to the linksys smart wifi administration site to my router?

All you need to do is to create a Linksys Smart Wi-Fi account and associate the router so you may access it wherever you are.

With regards to the browser, I sometimes have a challenge with IE11 so I use Chrome which works all the time. Hope that helps!
