The first thing I always try when my wifi is playing up is to completely forget the network on my device and reconnect from scratch. Go to wifi settings, tap the network name, select "Forget", then reconnect with the password. Simple but surprisingly effective.
For laptops specifically, outdated network drivers are a very common cause. On Windows right-click the Start menu, open Device Manager, expand Network Adapters, right-click your wifi adapter and select Update driver. Restart after.
Another thing worth checking: is your device's date and time correct? Some routers will reject connections from devices with wildly incorrect timestamps due to security certificate issues. Sounds odd but it happens.
Finally check if your ISP is having an outage in your area. Visit their website from mobile data and look for service status updates. Sometimes the problem has nothing to do with your device at all.

The reason windows confuses people is that most explanations describe the mechanics without establishing why those mechanics exist.
What you need to understand first: windows works the way it does because of constraints that aren't obvious until you look closely.
When you internalise that, the concept starts making more sense. In practice this means: the setup phase matters more than most guides acknowledge.
Version control (Git) is essential here — commit early and often.
Applied to practice: exceptions exist but they follow their own consistent rules.
Satch out for breaking changes between major versions.
One thing worth emphasising: with windows, the gap between knowing the theory and applying it in practice is wider than most people expect. Budget time for that learning curve and don't be discouraged when real-world conditions differ from examples.
