That is a very logical & informative explanation about the dual-band units which everyone locally is saying is a viable solution but I am now doubting based on your good information.
So my question is then, how far can ethernet cable be run. I have a big roll I bought 12 years ago I was going to run in a new building about the time I discovered usable wireless. It is a Category 5e Data Communications Cable UL Type CMR (Gray)-Riser Rated, says "gigabit speed-1,000MBits/Sec, 4 Pair/24 Gauge"
What do you think, can I run it 100 feet & have it work better than the N Router? .....and yes, I will bury it inside something as you suggest that is designed to be buried. I appreciate the help!
