I couldn't find a darn thing on their website, even if searching "reset wifi password" - "wifi" doesnt even come up! worst website ever. This is what they sent me via email:
Note that you can only do this with a device currently connected through HughesNet Internet either through WiFi or directly connected through a cable:
1. Go to the website: systemcontrolcenter.com or 192.168.0.1 (this is often down and unaccessible - **bleep**? there's also supposed to be a link under My Account???)
2. From the System Control Center page, click on Wifi Settings at the left side.
3. Enter the Administrator username and password. The default is admin for both username and password.
4. Once logged in, you will see the password for your Wifi in the middle of the page. Note that this is also the screen where you can change the password.
If in any case that you have forgotten your administrator password, you may press the Reset button at the back of the modem once then while rebooting press the WPS button at the front and hold it for at least 30 seconds to have the modem boot in default mode. Everything will change to default and the password for the WiFi will be the one at the back of the modem.
