BEST ROUTER EXTENDER TO USE

I have the ASUS RT N66U Router here in my North Room of the house and although the house is covered well with this router the outside area along the East wall of the house a little centered more to the south as well as my Camper setup which is due East of the house around 60-70 feet or so does not get real good coverage especially for steaming video..

There are too many on-line to look at and they all say they will work hehe...

My ASUS 66U has three antennas on it and also wired ports which I am currently using three of the wired ports.

I guess the extenders are really repeaters and will use one antenna to pick up the router signal and then re-transmit it out the second antenna...

I have had some cheap ones in the past but they never last very long... I used them in the kitchen window looking out over the back yard to the east...

I have 120VAC power at the trailer location and of course on the back patio area.

The dollar ranges are from $50 to $100 I guess and would like to order them from AMAZON... Of course I want one with all of the pass word protect modes...

Would like to hear from anyone that has used the extenders...

I have an overhang up under the house roof and would even like to mount something there out of the weather. Can run an simple extension almost anywhere out-of-site... Don't know if mounting one in the attic might not be a bad idea???

Perhaps it might be better to run a CAT5 Cable to the extender/repeater and not depend on it picking up WIFI mode from the router???? Have run such cables for up to 100s of feet in my work days with good results for office setups...
