i have a wrt54g that links to toshiba laptops with built in g wifi--it works ok, tho a bit low in some ends of the office. is it worthwhile to upgrade to an s or x router without adding the s or x pc cards to the laptops? i don't want to add a card to the slot on the laptops--past experiences with pc wifi cards have been disappointing and its more junk to deal with. would it be better to just wait for the new N router (what's time estimate for new standard) and gets a new laptop then w/ N built in. the linksys webiste offers the following vague comments: "Even your standard Wireless-G and -B equipment will work better when communicating with SRX-enabled devices." what do some of you knowledgable persons think? thanks.
