Thank you for the prompt response, I really appreciate it. And I would like
to apologize ahead of time in case I mess up the format.

Unfortunately my router has a check box under Advanced > Advanced Setup >
Wireless Settings that switches the router to AP Mode. I looked into the
manual after seeing the posting here and it's how I discovered it. It was
never checked until today.

"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.
