some evenings I can operate for hours without problems, other times the wifi drops out every ten minutes. last night was really bad, so I caved in and spent a little under £10 (US$16 equivalent) on a 6235anhmw off ebay, that included delivery. Even if I only valued my time at £1 per hour, far less than legal minimum, this card has cost me far more than a replacement.
I'm a fairly persistent person, I can work round most problems and get stuff working that others fail to do, but there's a time to admit defeat. Intel, you beat me. I shall never look at Intel products again and have faith they will work reliably and to specification, I shall always hold back and wait for other suckers to be early adopters and wait for reviews.
