The Airlink Super G Series was given to me because my friend had an extra one. I can say that it has been a very reliable wireless source that I use to this day for my home. This router provides support for four LAN port connections and can connect up to five wireless connections at one time. The system was relatively easy to set up with a setup CD and when plugged in, it finds the internet connection quickly and is up and running. Every once in a while it will hiccup and you will disconnect for a second, but within a minute it will be up and running again (this is rare and happens to any router). The router features security settings, and I use the WEP password to keep my wireless connection from other users. It does not come with a firewall I believe. The Super G modes dont' really seem to make a difference in speed from what I could tell. All in all, it is a reliable router that I would recommend.
