I attempted to install an alfa wifi signal booster dongle yesterday. My laptop shut off suddenly and then would not boot up. I finally got it to boot up, but noe it is very slow.

I did a quick search & it appears the Alpha Wi-Fi Signal Booster is supposed to connect to the wireless router, not the laptop. How are you connecting it & what are you connecting it to??

Once you connect it correctly & it is still slow, do a Repair install.
