I have a WRT1900AC
I have an issue where I cannot get the application to work on any computer or cellphone outside of my home. If I disconnect my cellphone from wifi, I get a "router is offline" error. Clearly it is online. If I reconnect the cellphone to wifi, I have full access with the app.
At work, I get the same message after logging in on the website.
I did a live chat with a rep, and she said it might be a problem on their end. The couldn't access my router either.
Anyone else having this issue? OR has anyone had the issue and found the fix?
