Wi-fi impression:
I've just done a quick test on its 'G' performance, comparing it with my favourite wi-fi device, a WGR614. Sorry, no 'N' devices.
With either router in the front right hand corner of the house, downstairs, and a laptop in the rear left hand corner of the house, upstairs..........so max indoor distance:
Running wavemon to each in turn......
8800NL Signal Quality (at its best alignment) 93% Signal Strength around -70db
WGR614 SQ 92% and SS around -68db
Signal Quality is remarkably steady for both
Signal Strength varies by +/- 5db (approx)
So very little difference observed.
