This is an Intel AX210 NGW WiFi card. It is a bulk product, with simple packaging. Accessories include a screw and a Phillips screwdriver. Made by Intel, there are generally no defects, but on HP, Lenovo, and IBM computers, there may be cases where the system prevents booting if parts other than the manufacturer's genuine parts are installed. This is a low-cost version for advanced users, so returns are not accepted. If the motherboard has an onboard WiFi function, it seems that the added WiFi may not be recognized unless it is turned OFF in the BIOS settings. Please contact the motherboard manufacturer's support for details. 【About the Bluetooth function】 Bluetooth uses the same frequency band as 2.4GHz WiFi and switches frequencies frequently in very short intervals through frequency hopping. In environments where 2.4GHz WiFi is congested, it may become unstable. This is a problem with the operating environment and not a problem with the product. As a countermeasure, you can switch WiFi to the 5GHz band and turn OFF the 2.4GHz band on the WiFi router, or limit the 2.4GHz WiFi by setting the bandwidth to a narrow setting of 40MHz or 20MHz to use Bluetooth. To link at speeds exceeding 866Mbps with an Intel WiFi card, you need to set the channel width to 160MHz in the WiFi router settings. Please note that many WiFi routers that can link at 1733Mbps or 2400Mbps do not have the option to set the channel width to 160MHz.
