I installed W8 on my Dell Studio 1735 computer. Wireless Internet access is very very slow. I have not this problem with W7 on the same computer. I tried it with an external Network cable. Very fast, 50mbps. I also tried it with an external USB Belkin wifi adaptor. It works fine. Computer has a Dell Wireless 1500 N WLAN Mini Card. Driver version:5.100.245.20 Date 2012-03-13. I cannot find any better driver.   I have one more problem that I don't have with W7.  I cannot rate the computer. The Windows experience index cannot go past the test of Direct3D 10 Texture Load Assesment.   Can anyone help? Thanks.
Is DELL 1510 N WLAN Mini card compatible with W8?
