every tech has their own opinion.. whats that old saying.. opinions are like azzholes everyone has one Im sure he will figure it out. I have done firmware upgrades with no problem myself as well.. but i have seen numerous people grab the wrong firmware and trash a router because they didnt know what they were doin thats why i simply suggested buy a new one if it works great if not return it.. better than getting frustrated over a firmware upgrade. Alot of the older routers dont have the nice fancy wizard to do it for you. Gotta load it the hard way. Another reason for why i said what i said
