In my company I have wi-fi configured on mikrotik router. Each device in LAN can connect to wi-fi without problem and this connection persists except one notebook, which regularly loses connection only to this one wi-fi. Other wireless networks can be connected without any problem. Only helps issue two commands (when connection is broken after maybe 15-20 mins I have to first disconnect from this specific wifi and then execute two below): Code: ipconfig /release ipconfig /renew I tried update drivers, set static ip configuration. Nothing helped. Do you know maybe what can produce this problem? What things should I put here to help you help me?
