Hello DesmoPedro, first of all, we have to keep in mind this adapter is single band, meaning 2.4 GHz only, but it connects to 802.11n. Secondly, are you able to detect any wireless networks at all?
I may suggest checking the wireless radio is on and running the manual diagnostics tool from Intel® Proset.
Please note the available options for wireless mode are the combinations of 802.11 b/g. However, 802.11n can be enabled or disabled separately in its own setting “802.11n Mode”.
