I ended up having to reset my WiFi extender, and I also reseted my modem twice more, and then factory reseted my WiFi extender. My modem and extended ate dual banded, its possible the 2.4ghz wasn't working but the 5.8ghz was. My laptop is the one connected to the 2.4ghz. Not everything make sense but I'm just going to accept that it works now. Thanks for all the suggestions and help you've given me, I appreciate it.
