My understanding is that 802.11 NAT, etc., connectivity from SL 7 to VirtualBox to MS Win does not work because the kernel releases for SL 7 no longer support this possibility. I know it functions in SL 6 because my spouse still has SL 6 on her laptop (her machine is underprovisioned effectively to run a 64 bit OS and it is not cost effective to re-provision the machine, although the CPU is an X86-64) and this works. This is necessary to run an application that must connect to the Internet and is not available for native Linux, only MS Win and Mac OS X. (For those who are curious, the application is an USA income tax preparation/paying program of which we have used an annual edition for many years under MS Win under VirtualBox under SL.) I have migrated my machines to SL 7. Given this, if I instead connect using 802.3 to a 802.3 port and do not use 802.11, will the standard NAT I mention above work? My understanding from previous responses/posts to this list is that the SL7 kernel series still does provide this necessary support for 802.3 but not 802.11. I have attempted to use a USB port 802.11 WNIC that is supported under Linux and purportedly under MS Win 7; VirtualBox does redirect the USB device to MS Win and MS Win "sees" it. However, the MS Win driver is lacking, and unless I have Internet MS Win connectivity, I do not know how to get the MS Win driver. Under MS Win, the driver seems to be gotten automagically from some MS Win repository, possibly one from Microsoft. If at all possible, I do not want to do any non-automagic systems work on MS Win, particularly as in most cases this seems to involve regedit (editing the MS Win 'registry", a poorly constructed and documented structure). Any information will be appreciated; otherwise, I will need to use my wife's SL 6 machine. Yasha Karant
