A small problem with my Wi-Fi connection

Hello everyone. Occasionally, when I turn on my laptop, the system is taking too much time to connect itself to the internet. The trick is to disable and then enable Wi-Fi again to have it connected. The strange thing is that it isn’t happening all the time - there are times when it is connected normally. What can I do to prevent this from happening? Thanks in advance.

Same problem here. Anyone have an answer?
