I can push range up by turning off the 802.11n mode so it appears that settings can alter range. Also, most folk don't like what happens as you get on the outer edges of the range.
For this round you should select based on reviews.
To the doubts which router to choose between these below
which has greater range Stand-Alone the rest?
* 1 - DLINK DIR-905L
* 2 - GTS TELECOM 81.0254ARB - BOX
3 * - TPLINK WDR-3600
