I have two Lenovo N586 laptops. Both of them will reconnect to our home wifi on their own. I have disconnected. It reconnects. I have disconnected and changed the tick to connect automatically. It reconnects. Did those things plus turned off wifi antenna. The wifi turned itself back own and reconnected. I did the latter plus turned on airplane mode. The machines turn on the wifi antenna and reconnect anyway. When looking at the airplane mode tick it is still on but the machine is online.
I restarted the router and changed the login code. That allowed me to "forget" the network. However, when it was still looking to get online. If I entered the new credentials the same trouble starts.
These machines share the same wlan with data sharing. They also use the same login for Google Chrome so that we both have access to the same bookmarks, etc.
Any ideas? Thanks in advance for the help. I used Bleeping Computer about 3 1/2 years ago to fix a problem. Now I'm back.
