Hey, we installed a TP Link Wifi extender that connects from the router into the power lines a while ago. The extension has taken over as the sole wifi output of the house and the router is no longer a wifi source. I have tried disconnecting the TP link and have confirmed that the extension is now the only wifi source, despite the router still functioning through ethernet. Even when the extension is removed I am not able to connect to the router through wifi. Is there any way I am able to re-enable the wifi on the router and if so do I need to access the router as an admin because the user/pass was changed and I don't have the details.
