I brought and installed a twin pack Telstra WIFI booster set 3 weeks ago and everything has been working perfectly up until yesterday, when the slave booster started to blink blue the swapped over to solid purple... I rebooted everything 3 times including the NBN router and the main Booster... All to no effect... I also pulled the power out of the slave booster for 4 hours and held the rest button on for 60 seconds... All to no effect... it is still off line and purple.
Is there another step? Everything in the house is working well and it is not near any other routers eg it has good full signal and was working well for 3 weeks.
