All the drivers are available from Gateway if you dig around for a compatable laptop that has the same chipset (there are several). Otherwise, go to Gateway and go the the MX8734 page, select components, select motherboard and specifications. The sheet will detail all the parts on the board, and you will get 99% from intel.com. The ethernet controller is a little hard, as it is listed under Networking at the Intel site, but you can then dig down and find it, the link for it is:http://downloadcenter.intel.com/Deta...ition&lang=eng
Try the above. As far as the wireless goes, this particular wireless setup seemed very crappy from the beginning. I tested it once and only once, as my father (whom I did this grand adventure for) uses DSL with an ethernet hookup only, and refuses to think anything wireless. I did pull an equally great stunt with another Gateway, but I specifically got one with a T7200 C2C and windows Media Center, so I never had to go through this mess with jury rigging what I should have gotten from them (Gateway). However, I do love the machine, and I have dragged it all over the country with no issues and it was 849.00 with a 17" screen 9 months ago when a C2D was running 1500.
The Intel chipset InF should work, even now, but you need to make sure you have the right InF for the right chipset. They had 943 and 945 chipsets mixed in, so that may be the problem, but I did get it working with it. I do think it has a poor directional antenna, or else the driver itself was not efficient. If you cannot get it from the Intel web site, post back and I will see if we can link it somewhere's.
