No link light while connecting to network
I got a new laptop to work with and noticed that if I plugged a network cable into it to connect to certain networks sometimes it worked sometimes it didn’t – I couldn’t even see a link light at the socket.
I thought this would be a driver issue of the laptop so I was ready to find a new driver for this network card.
So I opened Control Panel and System Properties. Then I clicked the Hardware tab and opened Device Manager.
At Device Manager I expanded Network Adapters tab and selected the ethernet controller of my laptop. I right clicked it and opened the properties window. My initial purpose was to find the driver version but I started looking at the settings.
So I selected the Advanced tab and eventually Speed & Duplex. Wait.. why is it set to 100 Mb Full? Hummm…. let me change that to Auto. Bingo… After applying the change I got a 1.0Gbs connection…
