I ended up getting the NETGEAR N600 WIFI Range Extender from AMAZON...
This model sits in my house window looking out over the back yard, patio area, and where I park my RV's...
Went with the WIFI repeater mode first just to see how well it worked with streaming videos and all is good so will not have to use Ethernet cables for now... Already watched a couple of last weeks GOLD RUSH TV shows from DISCOVERY CHANNEL for past two weeks sitting out in my lawn chair by the fire... Also had my POLICE SCANNERs all going at the same time with no problems with drop outs...
Used the simple method for coping my Router Unit name with an added '_2EXT' to it and used the same password for my router...
All setup just fine and all is SECURED... I get a full set of bars all over my back yard now where before it was maybe 2-4 bars and did do some drop-outs for me...
Good $50 spent here -
Thanks to all for the inputs...
