Poor quality product - unstable connection

The product is simple and easy to implement but the connection is unstable.
The WIFI connection quality drops (the witness turns orange then red) over periods of several seconds to several minutes, and nothing justifies this change (the WN2000RPT is 3 meters from my Freebox).

For use with low sensitivity to rate products: no problem (eg network printer).
For use where the flow or quality is important (eg network play): the product is strongly discouraged !!

By testing with an Apple Airport Express terminal, the problem does not arise.

Reading the forum NetGear the problem is known, but listed no solution was found.
So NetGear should stop marketing it !!!
