My MacBook Air (2017, 13.3 Inch model) repeatedly disconnects and reconnects (but says "No IP address") to WiFi after around 11pm. The issue stops at around 8am the next day, and everything works fine again. I can't explain it here, but I have uploaded a video of the problem on Youtube.
MacBook Air 13″, macOS 12.7
Can you confirm, what version of macOS is this >> My MacBook Air (2017, 13.3 Inch model) << running ?
I ask because your question is appearing in macOS 14 Sonoma which by all rights, this computer does not qualify to run.
I know, sometimes posting get placed in the wrong forum - it does occur though
macOS Sonoma is compatible with these computers

Open System Settings and search for 'downtime' and make sure it's not turned on and schedule to run between 11pm - 8am.
Check with whoever manages the wifi because it's possible to schedule when WiFi is turned on and off at the router / access point. For example, I use UniFi and I can do the following to prevent my kids from using WiFi when they should be sleeping:
I don't think it's any of that because other people can use the internet while I can't. My iPad can also use the internet fine at the times. It's also seemingly random and the hours where it doesn't work vary.

It could be interference, from other networks or from appliances. That would be very dependent on the specific physical location or room. Do you experience this, say when your laptop is in very different locations? A really good test would to be in a different building, or see if it happens when you are traveling outside your normal network.
It seems odd that it happens at night as that is when most other networks' and appliances' activity is reduced.
