There is just so many links, releases, errors etc that can mess things up if i do somthin wrong..but maby if i had some recomandations frome someone that where in the same shoes im in, maby then things will go along smoother. So what firmware do you recomend for my wireless router? One thing im wondering about is if my wrt54gs v.4.0 has any Firewall buildt in? if not will a 3rd party software fix that? And how will it be handled? onboard or via some windows program?
