My tech guy says use a hub,but I always get message that says IP addresses are conflicting with each other.He also says he can detect if I use router,I disagree.I,ve used wireless routers in the past with no problem.Now I,m trying to use wired router and I cannot get it to work.Any help would save my day.My tech also tells me I cannot use router because it just wont work.I also disagree.Please help!!!
