The wireless/Internet card failed on my computer failed. Rather than spending a large amount on a new card, I purchased this product as a stop gap.
It arrived within 2 days of ordering. I simply plugged it into a USB 3.0 socket and plugged the Ethernet cable in the other end and switched on the computer. My Internet was restored instantly. I cant discern any difference in speed between using this and using the original card.
If you have lost your Internet due to a faulty Wireless/Ethernet card than I highly recommend this product. The cost of it compared to replacement cards is ridiculously low.
