My Wireless adapter (a usb plug in) and my LAN disconnect from time to time and have to be reset using the troubleshooter. I have tried absolutely everything that I have found on the internet to try and fix the problem to include update/rollback/disable/unintall/reinstall drivers. I have deleted bonjour as that was a suspected culprit. I even put the IP Gateway in manually. As well as others that I can't even remember since I tried them so long ago. None of these seemed to help. I had no idea what was wrong but today and somewhat yesterday I noticed that in the "Network Connection Details" it said that the IPv4 and the IPv6 had a "Lease" date and an "Expiration" date. It just so happenes that the expiration date is the exact hour, minute, and second that the connection disconnects. It has taken me a year to find this and now I'm here to see if anyone has a solution for this ongoing problem.
