raysl,   The Intel® Centrino® Wireless-N 2230 adapter works ONLY n the 2.4GHz band and has Bluetooth.     Rick
Hi I have a new laptop, Inspiron 15R 5520, which comes with Intel Centrino Advanced-N 2230 network card. It can only detect my wireless-G netowrk at home, but not wireless-N. I have another computer that can connect to my wireless-N, so the network is working fine. I have updated the driver to the greatess and latest. Is this a common problem? Any help is appreciated?   Thanks Raysl
