Someone else's devices connected to my router, now my connection is unstable
Two days ago I woke up to notifications that an LG TV and a Magicjack device had connected to my wifi network.
I paused the devices and changed the wifi password. This caused every one of my devices to disconnect and be unable to connect until I was able to reboot the router/modem through xfi assistant.
After the reboot, I could reconnect my devices but now my Playstation 4 continuously loses the connection to online games when it never had before making them unplayable. It's also connected directly via an ethernet cable. I tried using both the cable and wifi but had the same problem.
I logged into my router via my PC browser and it is showing someone else's wifi SSID and password but it's showing my devices connected to the network.
All the xfi assistant will do is let me reboot but I haven't been able to reach a support rep. It seems like there's no mixup with someone else's service starting two days ago.
Does anyone have a fix for this situation?
