I looked into the manual after seeing the posting here and it's how I discovered it. It was never checked until today. >From the manual: "AP Mode. You can make the WNDR3400v2 function as an access point."

Channel selection isn't done by me, it is set to "auto" mode at the router settings which explains that it will choose the best channel. I appreciate you pointing that out because now it will give me more options to play around with. I have seen the ips posting else where and will test this once I configure the channel. Thank you.
