No longer sees 5.0ghz wifi
I recently got a new router with dual antenas, that has concurrent 2.4 and 5.0 ghz wifi running.
When i got it, i connected my xperia z1, nexus 7 fhd, and my 3 gf's gadgets (notebook, ipad 3 and galaxy s4) to the 5.0 ghz wifi (that one is running in N only mode).
A chromecast and a wd live tv box to 2.4ghz.
Yesterday, i came back home, and my Nexus 7 was not connected to wifi.
It no longer sees it, even if i set it to 5.0 ghz only in the advanced settings.
I am kinda lost :P
No amount of router or tablet reboots fixed it, and other devices connect fine... the tablet just says it is out of range.
