Inspiron 3543 WiFi Lockup
This new Inspiron 3543 had the hard drive replaced right off the bat. (About six weeks ago) Reinstalled Windows 10 and Windows 10 drivers from the Dell support website as listed for this laptop. This worked great for about one month, but after a difficult Windows Update session I started to see problems. I'll be online and the WiFi connection will be lost. When I attempt to reconnect to the WiFi network Windows freezes. Waiting does not help. I have to do a hard shutdown and restart the computer. Everything comes up fine, but it will do the same thing after a few hours online again. This has been going on for two weeks now.
