What should I do if my wifi data is abnormal and I can't get online?

The subject wants to get a solution to the abnormal problem of hotel wifi data, go to the internet cafe! My answer may disappoint you. I suggest not to use wifi in public places, which is inherently unsafe and the data is not normal now. If it's nothing important, bear it! If there is something important and there is no professional to solve it on the spot, even if it can be used, you still have a great risk of revealing your important information! In the end, it's up to you to weigh it!
