Why network parameters do not meet the requirements and the computer does not connect via Wi-Fi
Most often, this situation meets after you just configured the router. In particular, after put a wi-fi password in the router. The fact is that if you connected to the wireless network even before you have been set up, i.e., for example, connected to the standard ASUS RT, TP-LINK, D-Link or ZyXEL router, not protected by password , Windows saves the settings of this network so that in the future it is automatically connected to it. If you change the WPA2 / PSK authentication type when setting up the router, and put the Wi-Fi password, then immediately after that, Windows, using those parameters that have already saved, cannot connect to the wireless network, and as a result You see a message that the parameters saved on this computer do not meet the requirements of the wireless network with new parameters.If you are confident that all of the above is not about you, then it is possible and one more, a rare option: the router settings were reset (including at voltage jumps) or, even more rare: someone outsider has changed the router settings. In the first case, you can do, as described below, and in the second - only reset the Wi-Fi router to the factory settings and setting the router re-on.
