5Ghz sometimes not getting detected within same room. 5Ghz band signal very weak no range outside the room where router is kept. Used my old n class router as repeater for 802.11 N band to improve signal in other rooms for 2.4Ghz band. Probably should have gone for good models/brands.update-: Only band now works at a time. to get other band to work router must be restarted. bad quality router. seems like a waste of money. should have gone for a better expensive dual band router.
