I bought this router specifically for RADIUS authentication as mentioned on the datasheet provided on the NETGEAR website. Once arrived I was in for nasty surprise that no such feature exists. A quick search revealed posts like this [...] saying they were all mislead. I am waiting for an official response from NETGEAR on this. It appears that at somepoint they updated the firmware to version 2.0.1 and REMOVED RADIUS without updating the manual or the datasheet. Now I have to waste time dealing with this issue.
