&
urtwn0: at uhub3, port 3, addr 4 (disconnected)
(BTW there's no external hub, uhub3 must be inside laptop,
& there's no loose connection, laptop was not touched, all work was remote)
PS a typical sample comparison of scanned signal strengths
of one of the ~15 nets localy:
54M -49:-86 100 EP RSN WPA WME run0 big stick,
54M -69:-95 100 EP RSN WPA WME urtwn0 nano edimax EW-7811Un
so the edimax is typically down about 20 on left column on all ~15 local nets.
The aerial must be a minute fraction of the wavelength.
I suppose wavelengths are is approx:
3 x 10^8 metre/second / 2.4 GHz = 3/2.4 x 10^(8-9) m = 12.5 cm
& ~6cm for 5GHz band.
Cheers,
Julian
