I recently got this wireless router to replace a Linksys cable/dsl router. The power supply was starting to get noisy after a year or two's use and it was bugging me. So I got the Netgear and I'm extremely satisfied.
I was up and running in 5 minutes and that includes the time I spent setting up the security. (I'm very familiar with these type of devices so your results may vary.)
The security is very high with this device. You can specify which MAC addresses (and thus network cards) you want to be able to access the wireless network and you can also turn on WEP encryption. Furthermore, you can also turn off the SSID broadcasting which makes your access point act in stealth mode where people would have to know the name (SSID) you configured it with in order to connect. When you combine these three levels of security, you get a great system.
Besides security, it also has a much better web interface than the Linksys Cable/dsl router. There are more options for content filtering, logging, firewalls, etc. Besides that, I haven't had to reset it yet while I used to reset my Linksys about once every two weeks or so. This device is just more stable. Previously, when I would try to ftp to the public IP address of my FTP server from inside my LAN, it would hang my Linksys. This works perfectly with the Netgear.
To all the geeks out there, this is a great device. Check it out!
