I have had hn service for a couple years. 2-3 days ago I couldn’t access the internet. When I attempt to go online the browser displays a message that I must go to systemcontrolcenter.com to activate. When I go there, of course, there is nothing to activate. It does display the code 21.2.4 and says I am in walled garden mode. I have no phone and very spotty cell service at my house. I tried twice to resolve this through the support chat function. Both times my cell service cut off. I tried again today when I got into town and was told I need to call in to re register. I cannot place a call from my house/near the modem. I am hoping someone here has a solution!!
