Many thanks and apologies for the typo (did a minor edit above 

 )
I get the feeling that you suggest that between the G and the GS, probably the former would do.  Re:the 3rd party firmware, do I understand correctly that I need either an old model or Linux (which I dont use)?
Also, does the "54" in the model number suggest 54 Mbps?  Does Linksys do "108" models? (would an "108" be better or just a waste of money?).
Thank you!
