New problem , power light and radio lights on constant

[jerry6]

no lan lines are recognized , none of the lan lines light up , no light for internet either . When router is powered on power light comes on , 75 seconds later 2.4 radio light comes on , 20 seconds later 5.0 radio light comes on and that's all . Cannot log into router either , nothing changes this , have tried all recovery methods . What can be wronG now ? AC 66
