I fixed in my network, but the problem was in router security settings. Maybe the issue is in the security settings from the router, according to this link: [https://www.tp-link.com/us/support/faq/1533/][1]
In the router page, I discovered that the MAC address from my laptop was in a "Blocked DoS Host List", then I cleaned this list. Additionally, I increased the threshold values to 500.
