I have a WNDA3100v3. I am running Windows 10 and have a Hitron CGNVM-2559 cable modem/router. My wifi adapter will connect but only in 2.4 GHz and not 5. I have gone into the adapter settings and tried to force it to 5GHz and it will not connect to the router. I get no error message when I do this it just will not connect. There is about 10 ft between the router and adapter and it has a clear line of sight and shows full signal strength. All other devices will connect at 5 GHz and give me the appropriate speeds.

These posts are from almost a month ago and Netgear doesn't care.

Can the adapter see the 5GHz SSID? Any chance that the modem/router is blocking it? I'd check the router and Windows for possible issues.

Thank you for the reply. The adapter is showing both the 2.4 and 5 Ghz connections are available on the router. When I try to connect to the 5G it connects to the 2.4 instead. If i go into the adapter settings and force it to 5G it shows just the 5G connection in the Genie. When I try to connect to that connection the computer acts like it is trying to connect then just stop and isn't connected. There is no error message showing up when I do this. The router has been ran through basic diagnostics by the ISP (Mediacom) and every other device we have is connecting properly and at the correct speed. I have looked through windows 10 settings and don't see anything out of place but I'll admit I am FAR from and expert.

Hi, i have the same problem, my girlfriend has the adapter 30 cm from my laptop that can receive the 5Ghz Wifi but she can't, her adapter is connecting to Wifi 2,4Ghz only : (Windows 10 / Version 1.0.0.10 des logiciels
