So I'm currently home from college and started having this problem with the wifi. It will disconnect from both my phone and laptop overnight and will not reconnect until we reboot the router, but it does not do this on my brother's phone or desktop (I assume the desktop is find because it has a wired connection though, but that doen't explain his phone being fine). It not really a big deal, but It's been happening for several days now and my brother is getting annoyed that I have to keep turning off the router. I have looked this issue up online and the only solution I've found is that its an issue with the router and that we should get a new one, but our router is pretty new, we upgraded our internet maybe a little over a year ago. So I'm hesitant to believe its a problem with that. Any other ideas on what could be causing this, or is it definitely the router?

So it's the other way around, your phone and laptop are attaching on 2.4Ghz and his phone is attaching at 5Ghz and the 2.4Ghz band is probably saturated in your house with the neighbors around and causing this.

Try changing the channel either to 1, 6 or 11 (depending on what it is now) for 2.4Ghz on the router and make sure the bandwidth is set to 20Mhz (not 40).

I'm not sure exactly what router, its the standard AT&T one. My phone is a Galaxy Core Prime, and I have a dell laptop (Nothing particularly special, 1.80 GHz Processor), I have no idea what his computer is, but he has the New Google Pixel 2.

We had a similar problem with one computer [of the household's three].

IIRC we had to download a different driver with an *earlier* date than our laptop arrived with. :\

laptop is "Asus Vivo Book Flagship High Performance 15.6 inch (1366 x 768) HD Laptop PC"
Intel Pentium N3700 Quad-Core | 1.60 GHz | 4GB RAM | 500GB HDD | DVDRW | WIFI | Webcam | Windows 10 | Silver

Mark's suggestion of wireless interference on saturated 2.4 band is much much more likely.
Driver only explains the windows PC disconnecting, not the phone as well.
People are so quick to suggest to try 100 offbeat things instead of doing any sort of systematic troubleshooting (flowchart) to much more efficiently diagnose/fix the issue.
