> I too am seeing > urtwn0: timeout waiting for checksum report & 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.
