Why does the laptop not connect to wi-fi (writes the network is limited)?

Question

Domain Name System

Hello! There is a netbook Asus 1215n in which the driver for wi-fi Broadcom 802.11n Network Adapter is installed. I connect to any networks normally, except for one where the dir-620 modem is used in 802.11 B / G / N mixed c 2.4GHz mode - it writes limited access and the gateway does not ping.
Moreover, all other laptops and phones are connected without problems, regardless of the number (even when 1 netbook is connected, the picture is identical). Restarting the netbook and modem does not help. Every time you have to create a WiFi point on your phone and connect through it.
When I reinstalled the OS on windows 10, somehow I managed to connect (accidentally?), but because The laptop was very buggy, I had to reinstall it on 8.1 and again this problem.

What could be the reason and how can it be fixed?

Answer 1

Forced installation of the latest version of the wi-fi driver from the official site helped! The most interesting thing is that through the device manager, the driver was not highlighted in yellow and wrote that it did not need updates - like this :)
