My laptop won't connect to my home wifi but connects to any other wifi Answered

I am able to connect just fine to any other wifi network I've tried (including wifi networks around my college campus, and even my dad's home network). No one else has an issue connecting to the network, and I'm able to connect my phone just fine. Our bluray seems to have an issue connecting as well, but I'm not sure if it's related. The wifi symbol on the taskbar of my computer will sometimes indicate it can't connect, but will mostly show full bars but either way no pages will load. I've tried multiple browsers. What's even weirder is occasionally (though rarely, and lately never) it will work just fine for about half an hour and then stop working again. Where I am in the house has no effect. I have Windows 10 and an ASUS laptop, with Kaspersky. We have a "wireless gateway" for wifi. It's been going on for a while, and it started when we got the new modem but I had also just gotten the computer so I'm not sure what's going on.
