I guess my message posted after yours. Somehow yours just showed up.
No Internet Connection After Boot UP or Wake Up
This link is not how my problem occurred but it seems to be the same problem I have now. From uninstalling and reinstalling my wireless adapter I seem to have gotten rid of the virtual mini adapter mentioned in the above link. This could very well have been my problem from the beginning. The difference being that my wireless connection does not work at all.
To your question about the router I have a Linksys WRT54G V8. However the homegroup issue existed on other, more recent routers.
