I installed the tether app on my Android mobile device and the archer c2300 router comes up. When I press on the router I received the following message: "Login failed. You may be connected to a guest network, limited by Parental Controls or your network may be unstable." I believe the issue may be the app will not allow connectivity to a mobile device that is connected to a wireless network that is password protected. I connected a free wireless network (no password protection) and the tether app connected to the archer c2300 successfully. Can there be an update pushed through the tether app to allow device connectivity with password protected wireless networks?
