So here is my question and please excuse me for being a network tard. I have an old handy dandy Linksys WRT54GS that I have used for many many many years... Will I see any benefit if upgrading to something newer? Also keep in mind that I am hardwired and the only thing that uses its' wireless is my iphone or tablet. Also, I'm not too worried out hackers or any serious online threats. Should I upgrade, or is this giving me plenty of everything I would get from say a newer $100.00 model? Thanks!
