Hello, Good News...
My Time Warner Cable modem is(was) bridged, but as I mentioned the wireless was on; I had Time Warner turn off their 2.4 wireless, and my problems with the Dlink 880L 2.4 wireless as I mentioned previously went away; I have the 802.11n auto 20/40 setting on and it works as I think it should now with no drops and at fast speed.
However, the QOS still doesn't save changes after the first initial setup day, and Time functions under management still seems off as I have it set to Eastern DST and the correct time shows for Central (where I am) below it (when using the Dlink time server) . These to me seem minor issues to me at this time.
Thanks for your help!
