I do experience problem when some devices do not see 5Gz network at all: samsung laptop NP 700Z, Philips TV. 2.4 network is recognized and both devices are connected currently to. 5Gz in router is on auto and 40 Mhz (switch to 20 and 20-40 does not help). Unfortunately only few canals choices available from 36 to 48 or similar with no result (because EU location probably). Inssider also does not detect 5Gz and the only device which see it son's Dell studio XPS. Will investigate network card properties there... I have read on one forum that 5Gz properties were changing from Firmware to Firmware. 5GZ network from Linksys e3000 was perfectly seen by TV before. Anybody can advice?
