This is my first post on HWZ. Bought the Wind U100 after Comex promotion so only got a 6-cell battery instead of 3+6 cell batteries.
Checked for latest U100 WLAN drivers at msi.com when I was trying to fix machine's erratic wifi connection & discovered they had several driver files posted there. Downloaded all 3 driver files provided & found on opening the RTL file that it was the wrong driver (Read Me file says to identify which WLAN card is installed on Wind before selecting appropriate driver). Anyway, my Wind is installed with the Ralink Tech b/g/n card so I needed the RT2700 driver. Pleased to report that after driver upgrade, it is connecting flawlessly with my N-router at home, even from the kitchen downstairs, which I can never do with my full-size notebook installed with Realtek b/g card. Shall go test out Wireless@SG hotspots this weekend.
Another problem I had was that the touchpad was not listed under Mouse in Control Panel and only ps/2 mouse was listed. Nonetheless, I assumed I had a Sentelic pad based on discussions in msiwind.net and went ahead to install the driver for Sentelic touchpad (finally found it after great difficulty in the U100 FAQ page in msimobile.com). Update has enabled me to scroll vertically using the 'hot' corners of the touchpad, but still can't configure other tap zones unlike the Synaptic touchpad.
