The router we provide to our Fiber/DSL customers is per-configured by NorthWind prior to delivery. Resetting the router will also reset the the NorthWind configuration. You should NEVER press the 'RESET' button on your Wi-Fi router unless you know ALL the settings that are required to make it right.
MANY troubleshooting wizards/FAQ's online will instruct the customer to press the RESET BUTTON on the Router.
Do NOT do this!
You WILL lose Internet connectivity, as well as clearing your Wi-Fi encryption. Instead, you should Power Cycle your router off for 2 minutes and then back on to clear suspected problems.
