for a variety of reasons. Pre-N and the soon to be ratified N standard will be the norm in the not too distant future.
As far as your existing problem, the first thing I would do is update the firmware for the router. This cures many out-of-the-box issues.
I have 2 relatively new computers running XP that I have networked with an ethernet router. they share cable internet, a printer and files. my problem is at least twice a week I can't connect to the internet on the primary computer. when I go searching for the problem, it is always unable to "see" the second computer and I have to run a network setup on windows. after I do that all is good, but it is getting beyond annoying. what could the problem be?
also, I have been looking lately at getting a wireless setup, instead of what I have now...so that I can hook up other components to the network (DVR now, laptop and other in the future). will that solve this dropping problem...and how good do those wireless routers really work between walls? I have one computer upstairs, one downstairs (about 15 ft away, underneath), and one network compatible DVR in the room over from upstairs computer. I've done all kinds of research online and I would have to get the "a" type to prevent interference from my phones but the reviews are mixed and confusing about going through walls and floors.
TIA very much for any help!!
