I bought this router like 5 days a go and start having some connectivity issues with some devices, currently handle like 25 wireless devices so i try couple configurations with no luck so decide to try the firmware upgrade to 150122, but after installing the firmware router only run for under 1 minute and freeze with all led's on, I already did a hard reset, power off power on and does the same thing only works for under 1 minute... I am afraid the firmware affect the device... or is causing some sort of conflict... now is useless is there a manual roll-back to factory firmware?
