1PCS ASM1064 M.2 WiFi to 4 3.0 adapter extension cables connector Be sure to confirm the A key or E key M.2 NGFF WiFi slot interface protocol, which only supports PCIe protocol WIFI network card interface use! Not supporting CNVI protocol M.2 WiFi network card interface! The 3G/4G/5G network card interface is also not working (the KEY bit of this interface is different, it is a Bkey, be sure to figure it out)! It's not something that can be used just by inserting this card into your machine interface! Thereis one version of flexible cable: 10cm cable . The longer the cable, the greater the signal attenuation, so the longer the cable, the greater the impact on speed. Try to choose the appropriate length! Product features: 1. This adapter card uses ASM1064 bridge chip and only supports insertion into PCIe protocol A key or E key M.2 NGFF WiFi slot interfaces. It does not support any CNVI protocol interfaces or 4G/5G network card interfaces! 2. system is drive free. For other systems, please refer to other similar controller boards. If the chip model is the same, other boards can use this one!
