My father just bought a new imac for the office. Currently, we have a 4 port router netgear router with wireless. We have four computers hooked up directly to the router, and his computer is right next to the router, but we have no more ports to plug it in, therefore we have his new imac running on wireless. The problem is, the router we have for some reason stops working ever few days, and we need to unplug it in order for it to work again. If we got a new router, my dad would prefer to have his computer hard wired. Are there any wireless n routers with more than four ports built in? If not, will i run into problems if i get a four port wireless router, and then get a regular four port router and piggy back into that? Will there be any issues as far as firewall or anything? Any suggestions?
