Hi All ;
It's been just 4 days since I bought it. First three days I've experienced a few lost connections and a reset worked, though I wasn't happy that a high-end router does this. 
However yesterday, suddenly all wifi SSID's disappeared , although less on the unit are all blue. Also GUI shows them as enabled. I tried disabling smart connect, changing SSID's, enabling/disabling, rebooting and finally a factory reset; none worked. 
I updated the FW to 1.13b and suddenly wifi came back, however when I enabled smart connect it once back died. 
My region is MEA , HW revision is A2
I upgraded to 1.13 the first date and wifi worked for 3 days afterwards
Everything else seems to work OK. 
Any help appreciated
