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?
