I'm looking to buy an Airport Extreme, but then saw some new models from Linksys (WRT350N) and Netgear (WRT350N). They have similar specs to the Airport (Gigabit switch, Wifi N etc.) Can anyone recommend one over the other ? Does the Airport have as many settings and features as the Linksys / Netgear with regards to Firewall / Port Forwarding etc. ? Thanks in advance !
