bought this adapter from amazon for my windows 8.1 laptop to connect to a public hotspot available at a bar across the street from my place. the cd that comes with it wouldn't let me install the wifi utility, but the windows wifi utility recognized it (after downloading window 7 drivers manually). however... the connection speeds we unreliable and inconsistent. i couldnt stream youtube vids or load pages reliably.
i've been searching for drivers (for win 8.1 (64bit) for it for the last 2 days, without luck.
i was about to admit defeat and accept that this adapter wouldn't work "correctly" for win 8.1, but as a last ditch attempt, i searched for drivers for "realtek rt8187 wireless 802.11 b/g" instead of "alfa wireless" drivers.
