Tiny little thing. Impressive.
>This uses the Realtek RT5370 chipset.
>Signal strength was excellent but quality was almost zero.
I think you mean signal strength was lousy while link quality
was high. The way it works is that link quality is really
a measure of the bit error rate. If there's little data moving,
the link quality tends to be a rather high number.
Also, some drivers and chipsets seem to have problems reporting the
signal strength and quality. I'm not sure of the issue, but I have a
USB dongle (chipset unknown) which reports zero signal strength at all
times. However, it works just fine.
>I double checked the connection. It's using "G" as I don't have an "N" router.
Good. That makes troublshooting less complicated. However, if your
driver allows you to turn OFF the "N" features, I would try that just
to see if it helps.
Tell me about the corner reflector. How is the antenna positioned?
What is the antenna orientation relative to the reflector?
What OS are you using?
What program are you using to display the signal strength and quality?
Duz it work normally without the corner reflector?
Want me to recycle my previous rant on why using an omni to illuminate
a dish (or corner reflector) results in plenty of receive gain, and
miserable transmit gain?
>Is this some sort of modulation issue ?
>Any idea Why the huge drop in performance ?
Nope, not enough info. (Hint: Numbers please).
>Ps here's the unit, which at $5 AU is amazing value. Quite well made too.
I'm tempted to buy one just to play with it. Looks nice on paper.
