@Canuck_Lad Here's the algorithm which your mobile is using for roaming - shifting Wi-Fi network association: https://docs.samsungknox.com/admin/knox-platform-for-enterprise/kbas/kba-115013403768.htm...

@Jdhn On the main router (WR940n) replace the internal port 443 with 8090 and save the settings: Here I assume that you're using port 80 for TL-WA801ND WebGUI access (when you're connected to it)....

@serbian_user With AX10 you can use the AP mode only to expand your network.

@kowei Your Internet connection type is Bridge, that's why you can't configure port-forwarding: In bridge mode everything is passed through, so no point to port-forward.

@Deezla Connect your laptop directly to your main router and test the speed. That way you can determine where the problem is, with C80, your main router or even your ISP.
