I have an Acer Aspi9re 7741Z-4643 laptop with Windows 7 installed. I test with Knoppix 6.7.1 from a USB boot drive and now with 7.0.2 from a USB drive and from the DVD. I am able to connect to my wireless Linksys router and I'd be happy to try to duplicate your situation or help test - me on my PC and network and you on yours
