I'm running Ubuntu Hardy Heron on an Acer aspire 5570Z. I've been having alot of trouble getting my wireless working and then I came upon the following Ubuntu Linux on the Acer Aspire 5570Z (5570-2977)

It looks like a very possible fix, however, When I go to system/admin/Hardware Drivers it does not open. I am not sure as to why this is, as synaptic won't open either. Can someone please help? Help getting Synaptic working would be great but I am mostly concerned with the Hardware Drivers menu because I am dying to get my wireless working again
