What do you mean "reset": Did you just unplug it from the wall then plug it back in, reboot it from the web interface, or did you hold in reset button in the back?
Hopefully, you didn't do the latter, which can reset a lot more than just your wifi.
Thank you for the info. Are you able to connect to one of the wi-fi SSIDs or plug a computer directly into the modem? I will need you to try and access http://systemcontrolcenter.com if you can at least connect to the wi-fi. If you can connect to the wi-fi but can't get to that link, please try accessing http://192.168.42.1
Glad to hear we're a step closer to getting the issue resolved. Please let me know if the modem change does not resolve the issue.
I see that the modem was delivered a couple of days ago and just wanted to check in and see if you've managed to get back online?
Amanda or another HN employee will likely respond to you today, but sometimes they're not available right away, so it might take a bit.
