When I search the Internet for any parts to add to my computer, I often find parts on sale at steeply discounted prices. If I buy from a discount seller, I might not be getting a retail part, or worse, I might be getting a counterfeit. Buying from an authorized retailer is a good strategy for avoiding counterfeit parts.
Counterfeit products are a problem in many industries. You might think of counterfeit products as something sold on a street table or in a flea market, but plenty of these knock offs are sold online.
Sometimes you might encounter counterfeit Ethernet adapters labeled as Intel adapters. Counterfeit Ethernet adapters tend to be manufactured as cheaply as possible. The counterfeiters are not worried if the adapter will fail to work when you install it, perform poorly, or break after a short time. You might not find out that your adapter is a counterfeit until after the adapter fails, and you try to return it for a replacement.
If you have a counterfeit, there is no one to turn to when you encounter problems. The bargain can turn out to cost you more than a genuine adapter when you take into account the cost of buying a replacement, suffering from poor performance, or being without a working network connection.
Fortunately, finding a source for genuine parts is not difficult. Retail versions of genuine Intel® Ethernet adapters are sold through authorized retailers and supported by Intel Customer Support. If something goes wrong with the Ethernet adapter because of a manufacturing defect, buyers are covered by Intel’s limited lifetime hardware warranty. Software and driver updates are regularly available from Intel Download Center.
In short, if you want to have the peace of mind from knowing the adapter will work as expected, along with the limited lifetime hardware warranty and access to Intel Customer Support, then your best bet is to buy from an authorized retailer.
