Input:
What can I say about this router other than it is the worst equipment that I have ever purchased. I bought it new from a national store in my area on Friday. Saturday I noticed intermittent problems such as the Access Point could not be found, then it came back up in 20 seconds. I was using it 2 days later (on Sunday) when all of a sudden it stopped working entirely. The Power LED flashes repeatedly signaling that there is a problem with the router itself. I tried resetting the router, disconnecting power, leaving it off for hours and trying again just to rule out that it was a temporary problem. No luck. I am taking it back to the store today after work and replacing it entirely with a different brand. I own my own business doing network & computer consulting and I am going to make sure that if my clients are looking for wireless, they are going to stay far far away from Linksys.
On a side note, their documentation leaves a LOT to be desired. In the users manual, they keep referring to a DIAG LED that does not exist on this router. It would be nice to actually have a users manual for the exact product instead of one that roughly mixes all of their wireless routers together.
