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.

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.

I believe (had a similar wndr device) that it has something to do with
the way the device bridges wifi to the lan/wan. On mine, with it
checked, I was able to use the device as a stand alone AP rather than an
AP/Router. Trying to do that without it checked enabled some additional
firewalling on the lan/wifi bridge.

I also have a WNDR3400V2, which has been functional as a 2.4/5 GHz AP for the
two years that I have owned it, and that box has never been checked. I have no
idea what might be its effect, but it certainly was an AP before you checked
that box.

I never select the auto channel selection. You never know what strong sources in
your neighborhood might be off when it makes the choice.
